    FERREN, Senior Judge: Petitioners Sheridan Kalorama Historical Association
    and Sheridan-Kalorama Neighborhood Council (collectively “petitioners”) seek
    review of an order of the Board of Zoning Adjustment (“BZA”) granting the
    application of the Federation of State Medical Boards (“FSMB”) for a “special
    exception” to use its existing residential building (the “Property”), located at 2118
    Leroy Place, N.W., as an “Advocacy” (lobbying) office. The petition for review
    challenges the BZA’s findings and conclusions that: (1) FSMB is qualified for a
    special exception as a “nonprofit organization” under the zoning regulations; (2)
    FSMB’s use of the Property will not “tend to adversely affect the use of the
    neighboring properties,” nor create “adverse impacts on parking and traffic”; and (3)
    FSMB is not required to seek a “variance” because the Property has a gross floor
    area (“GFA”) greater than 10,000 square feet. We reject petitioners’ first and third
    challenges but remand the case for the BZA to afford the required “great weight” to
    the recommendations by the District of Columbia Office of Planning (“OP”) on
    petitioners’ second challenge as to the effects of the special exception on “the use of
    the neighboring properties.”
    I. Facts and Proceedings
    3
    A.     The Property and Leroy Place, N.W.
    The Property is a three-story building situated within an R-3 zone 1 in the
    Sheridan-Kalorama Historic District. It was built in 1902 and has been used mostly
    by foreign governments (including Hungary and Colombia) as a chancery until the
    Colombian government sold the Property to FSMB on July 18, 2017. The Property
    sits on a large rectangular-shaped lot measuring 5,124 square feet in land area, facing
    Leroy Place, N.W. (a narrow one-way street) on the north and abutting a public alley
    on the south. Single-family dwellings occupy the east and west sides of the Property.
    Roughly seventy-five percent of the neighborhood on Leroy Place, N.W. is
    residential; the remaining twenty-five percent is non-residential, principally
    embassies, the Russian Cultural Center, and a hotel. According to the District of
    Columbia Department of Transportation (“DOT”), the Property is “located less than
    250 feet from Connecticut Avenue, N.W.,” about “500 feet from Connecticut

    An R-3 zone is a zoning classification which allows row dwellings as a
    matter of right. 11 DCMR § 105.1(a)(3). The “Future Land Use Map,” as part of
    the Comprehensive Plan, designates an R-3 zone as “moderate density residential.”
    10-A DCMR § 225.4. This designation is used to define the District’s row house
    neighborhoods, as well as its low-rise garden apartment complexes.              Id.
    Furthermore, the “General Policy Map” of the Comprehensive Plan designates
    Leroy Place, N.W. as part of a neighborhood conservation area, “a category used for
    primarily residential areas in which development is [l]imited . . . [and] small in
    scale.” 10-A DCMR § 223.5 (2014).

    and the DuPont Circle Metro. Moreover, two parking garages are within one- and
    two-tenths of a mile from the Property.
    B.     FSMB’s Application for a Special Exception
    FSMB is a Nebraska nonprofit corporation, with headquarters in Euless,
    Texas, composed of seventy state and territorial medical “licensing” and “discipline
    boards” in the United States. It has 168 full-time employees, eight of whom are
    stationed in the District of Columbia. According to its articles of incorporation,
    FSMB is “organized exclusively for scientific and educational purposes.”2 For its
    operations in the District, FSMB explained that it annually spends about $400,000,
    or roughly one percent of its budget, on “advocacy” (which means “lobbying” under
    2
    FSMB’s more specific purposes include: (1) “keep[ing] itself and its
    members informed concerning the medical and other healing arts practice acts of the
    District of Columbia, the several states of the United States . . . , ” (2) “study[ing],
    determin[ing], and/or advanc[ing] the adoption and maintenance . . . of adequate and
    uniform standards for licensure in medicine . . . ,” (3) “develop[ing] and improv[ing]
    the quality of licensing examinations given to members of the medical profession,
    and . . . assist[ing] by means of research and study the member medical boards to
    improve the quality of their examinations,” and (4) “obtain[ing] and disseminat[ing]
    information regarding proposed legislation and administrative actions affecting the
    healing arts and licensure.”

    a Senate Disclosure rule) and is exempt from federal income tax under 
    26 U.S.C. § 501
    (c)(6).3
    FSMB bought the Property as a permanent location for its “Advocacy office.”
    On October 23, 2017, it filed an application under the zoning regulations for a
    “special exception,”4 entitling it, as a “nonprofit organization,”5 to use its “existing
    residential building[]” for a nonprofit purpose. 6 To enhance its prospects for
    obtaining favorable consideration, FSMB proffered various restrictions on its use of
    the Property, such as limiting the number of employees in the office to twenty-five
    and agreeing to notify neighbors in advance of each quarterly reception there,
    hosting no more than fifty guests.

    A § 501(c)(6) organization includes “[b]usiness leagues, chambers of
    commerce, real-estate boards, boards of trade, or professional football leagues
    (whether or not administering a pension fund for football players), not organized for
    profit and no part of the net earnings of which inures to the benefit of any private
    shareholder or individual.”

    11 DCMR U § 203.1(n). The zoning regulations define a “nonprofit
    organization as: An organization organized, registered with the appropriate
    authority of government, and operated exclusively for religious, charitable, literary,
    scientific, community, or educational purposes, or for the prevention of cruelty to
    children or animals; provided that no part of its net income inures to the benefit of
    any private shareholder or individual.” 11 B DCMR § 100.2.

    To obtain a special exception, FSMB had to satisfy a two-part “general”
    requirement: that its nonprofit use of the Property as an office [1] “[w]ill be in
    harmony with the general purpose and intent of the Zoning Regulations and Zoning
    Maps” and [2] “[w]ill not tend to affect adversely the use of neighboring
    property. . . .”7 Only the second general requirement is at issue here.
    In addition, FSMB had to comply with eight “specific” requirements, the first
    two of which are in the subsection heading, the last six of which are numbered. 8
    That heading provides that the building must be an “existing residential building[],”
    used by a “nonprofit organization” for nonprofit purposes. As to the other specifics,
    (1) the building must either be “listed in the District of Columbia’s inventory of
    Historic Sites” or “located within a district, site, area, or place listed on the District
    of Columbia’s Inventory of Historic sites”; (2) “the gross floor area of the building
    in question, not including other buildings on the lot, [must be] 10,000 square feet
    (10,000 sq. ft.) or greater”; (3) the use of the building and land “shall not adversely
    affect the use of the neighboring properties” (reflecting the second general

    11 DCMR X § 901.2. (c) (“such special conditions as may be specified in
    this title”); see 11 DCMR U § 203.1(n) (1)-(6); Decision and Order at 9.

    requirement quoted above); (4) “the amount and arrangement of parking spaces shall
    be adequate and located to minimize traffic impact on the adjacent neighborhood”;
    (5) “no goods, chattel, wares, or merchandise shall be commercially created,
    exchanged or sold” on the Property, except for items “related to the purposes of the
    nonprofit organization”; and (6) the BZA, “after review and recommendation by the
    Historic Preservation Review Board,” must approve “[a]ny additions to the building
    or any major modifications to the exterior of the building or to the site.” 9
    Prior to the BZA’s public hearings on FSMB’s application, multiple parties
    weighed in, expressing their approval or disapproval. First, a multitude of Leroy
    Place, N.W. residents submitted letters opposing FSMB’s application, expressing
    concerns about increased density, traffic, pollution, noise, and erosion of the
    residential nature of the neighborhood. Second, on November 20, 2017, Advisory
    Neighborhood Commission 2D (“ANC-2D”) convened a public meeting and
    resolved to oppose FSMB’s application, without stating its reasons. Third, DOT
    filed two reports, concluding that FSMB’s application “will have no adverse impacts
    on the travel conditions” of the District’s transportation network, while
    acknowledging “a minor increase in vehicular, transit, pedestrian, and bicycle trips.”

    8
    Fourth, OP filed a report on January 25, 2018, recommending approval of FSMB’s
    application, subject to conditions (among others) limiting the number of employees
    stationed at the Property to fifteen, prohibiting FSMB’s employees and visitors from
    parking on Leroy Place, N.W., and requiring annual meetings and events to be held
    off-site. OP further conditioned its recommended approval on FSMB’s providing
    documentation: (1) that “record[s] information regarding expected deliveries and
    visitors to the site,” and (2) that the Property satisfied the GFA requirement.10
    C.      BZA’s Public Hearings
    On January 31, 2018, the BZA held its first public hearing on FSMB’s
    application. Petitioners launched their opposition through the testimony of two
    expert witnesses, one opining on the definition of “nonprofit organization” 11 in the
    applicable zoning regulations, the other testifying on land use policy. The first to
    10
    In addressing the approval process, FSMB asserted, and the BZA agreed,
    that the GFA requirement is “something that the zoning administrator would
    determine.” They also agreed that the District of Columbia Department of
    Consumer and Regulatory Affairs (“DCRA”) “would have to verify” the GFA of the
    Property when FSMB applied for a building permit. However, petitioners noted
    wariness that given DCRA’s heavy workload, it would give only cursory review to
    the submission by FSMB’s architect.
    11
    See supra note 5.
    9
    speak, Nancy Kuhn, a tax law expert, testified that the definition of a “nonprofit
    organization” under the zoning regulations reflects the requirements of the tax
    exemption for charitable organizations under 
    26 U.S.C. § 501
    (c)(3), 12 and that
    FSMB failed the “operational test” under that provision.            She added more
    specifically that, rather than operate “exclusively for charitable purposes” – that is,
    “for the benefit of the public,” as required of a § 501(c)(3) organization – “they
    operate for the benefit of their members to promote the medical profession[,] which
    is appropriate for a 501(c)(6)” (FSMB’s exempt status)13 but not for a 501(c)(3). She
    explained that FSMB’s activities promote the “business interests of the physicians”
    in operating “a program of testing” the qualifications of physicians who seek
    certification as “specialists.”
    12
    
    26 U.S.C. § 501
    (c)(3) provides: “Corporations, and any community chest,
    fund, or foundation, organized and operated exclusively for religious, charitable,
    scientific, testing for public safety, literary, or educational purposes, or to foster
    national or international amateur sports competition (but only if no part of its
    activities involve the provision of athletic facilities or equipment), or for the
    prevention of cruelty to children or animals, no part of the net earnings of which
    inures to the benefit of any private shareholder or individual, no substantial part of
    the activities of which is carrying on propaganda, or otherwise attempting, to
    influence legislation (except as otherwise provided in subsection (h)), and which
    does not participate in, or intervene in (including the publishing or distributing of
    statements), any political campaign on behalf of (or in opposition to) any candidate
    for public office.” (Emphasis added).
    13
    See supra note 3.
    10
    A member of the Zoning Commission who was sitting on the BZA for this
    case expressed considerable skepticism about Ms. Kuhn’s testimony.           As the
    commissioner put it, “educating their members, making sure that they are providing
    excellent medical service, isn’t that a, I mean ultimately that’s a benefit to the
    public.”14 He continued, “I’m not even seeing for the benefit of the public in the
    definition.”
    Ms. Kuhn replied with a new theme: that the last sentence in the zoning
    regulation’s definition of “nonprofit organization” precludes inurement of any net
    income “to the benefit of any private shareholder or individual.”15 That sentence
    (which also appears in FSMB’s § 501(c)(6) exemption)16 precludes such benefit to
    an FSMB “member,” she said, apparently referring to the benefits (professional
    certifications) physicians receive from the fees they pay for “testing services” that
    allegedly generate “$40 million worth of revenue” for FSMB. The commissioner
    observed that her argument “might be relevant” if “this were a tax case,” but he
    14
    As a 501(c)(6) organization, FSMB must operate to improve some common
    business conditions of its members, including the District of Columbia Board of
    Medicine, whose mission is to “protect and enhance the health, safety, and well-
    being of District of Columbia residents.”
    15
    See supra note 5.
    16
    See supra note 14.
    11
    stressed (not entirely to the point) that the zoning definition “is not the IRS
    definition.”
    The next to testify, petitioners’ land use expert, Ellen McCarthy, opined that
    “the major adverse impact” on the neighborhood of a special exception for FSMB
    would be “the destabilizing of the residential real estate market.” She summarized
    that granting FSMB’s application would “put a quick stop” to the recent trend in the
    Sheridan-Kalorama Historic District toward restoring “formerly non-residential”
    buildings “back into homes.”
    Toward the end of the hearing, BZA members raised several issues requiring
    further input from the parties about the building’s “floor area” and “rear loading
    dock”; FSMB’s “plan or idea behind having 5 temporary employees beyond the 15
    full-time” (raised after its application for special exception had been filed),17 and
    FSMB’s “articles of incorporation,” “frequency of meetings,” “smoking policy,”
    plans for “after hours and weekends,” and “overnight guests.” The BZA therefore
    kept the record open and scheduled a second hearing for February 21, 2018.
    17
    A representative from OP had reaffirmed the agency’s approval of FSMB’s
    application by emphasizing that OP’s recommended conditions would limit the
    number of employees to fifteen and “the visitors and staff to foot traffic.”
    12
    During the second public hearing, petitioners presented testimony from two
    neighbors living next to the Property, both of whom expressed concerns about
    “substantial adverse impact in regards to traffic,” blocked driveways, and smoking.
    Petitioners also reemphasized their earlier arguments at the second hearing, stressing
    that FSMB does not “operate exclusively for charitable purposes,” as allegedly
    required for nonprofit status under the zoning regulations governing special
    exceptions. They further insisted that the BZA should not rely exclusively on the
    engineering and architectural report of FSMB’s expert, which calculated the
    Property’s GFA to be 10,825 square feet and thus obviated the need for a variance.
    Petitioners instead urged the BZA to consider their architectural expert, whose
    calculation purportedly proved the GFA was below 10,000 square feet. They
    stressed that concern because FSMB’s claimed exemption from an area variance
    “goes to the heart of whether [FSMB’s] use is in harmony with the zoning
    requirements.”18 Petitioners’ expert was made available for questions, but none was
    asked by the BZA.
    18
    FSMB’s initial application requested both a special exception to use the
    Property as an office for a nonprofit organization and an area variance from the GFA
    requirement of ten thousand square feet “or greater” under 11 DCMR U
    § 203.1(n)(2). However, according to FSMB, it engaged an engineering firm to
    provide a topographic survey, and the result showed that the Property has GFA
    greater than ten thousand square feet, prompting FSMB to amend its requests for
    zoning relief to eliminate an area variance.
    13
    At the close of the second hearing, the parties were requested to submit
    proposed findings of fact, conclusions of law, and “whatever conditions you do or
    don’t agree on, after talking with the opposition.” 19
    On April 18, 2018, after reviewing the requested submissions, the BZA
    granted FSMB’s application “for a period of five years,” subject to the following
    conditions (in addition to those imposed by the zoning regulations): 20 (1) A
    “maximum of eighteen people may work on site”; (2) FSMB may hold “a maximum
    of three committee meetings per quarter during business hours” limited to 25
    invitees; (3) it may hold “an annual meeting or reception” with 50 invitees that must
    end by 8 p.m.; (4) “Staff and visitor parking will be in nearby garages only and on-
    street parking will not be allowed”; and (5) there cannot be “expansion of the
    existing building footprint[,] and other extrinsic alterations are subject to approval
    19
    After the second hearing, OP submitted a supplemental report, on March
    21, 2018, modifying earlier recommendations to say: (1) there must be no more than
    fifteen “people,” rather than “employees,” working at the Property; (2) FSMB may
    hold up to three committee meetings per quarter, hosting no more than fifteen
    invitees per meeting; and (3) FSMB may hold a “reception” for fifteen invitees every
    quarter, ending no later than 8 p.m.

    followed.
    II. Standard of Review
    A.     General Rules
    In reviewing a zoning action, we do not reassess the merits of a decision by
    the zoning authorities.22 But we must “consider whether the findings made by the
    BZA are sufficiently detailed and comprehensive to permit meaningful judicial
    21
    Other conditions (most of which were recommended by OP) require
    restriction of all deliveries to weekday office hours; loading is restricted to the alley;
    the premises will not be rented or otherwise used for an event by a third party;
    fundraisers are prohibited; and FSMB and ANC-2D will “establish a neighborhood
    liaison to provide a forum for concerns and provide information about [FSMB]
    activities to property owners within 200 feet of the [Property].” There also shall be
    “security lighting,” a “24-hour emergency response service,” “a dedicated space for
    at least three bicycles” in the building’s basement or garage; there shall be no
    smoking on the premises; and FSMB shall “give notice and a copy of plans to the
    liaison, ANC, [the petitioners], the neighbors whose properties abut the site, and to
    Mr. Guinee” (a former petitioner).

    review of its decision.” 23 If they are, “[w]e will not reverse [the BZA’s decision]
    unless its findings and conclusions are ‘[a]rbitrary, capricious, an abuse of
    discretion, or otherwise not in accordance with law;’ in excess of its jurisdiction or
    authority; or ‘[u]nsupported by substantial evidence in the record of the proceedings
    before the Court.’”   24
    Moreover, we accord “great weight” to the BZA’s
    interpretation of the regulations that it is charged with enforcing, and that
    interpretation must be upheld “unless it is plainly erroneous or inconsistent with the
    regulations.”25
    B.     Heightened Level of Scrutiny?
    Petitioners invite us to apply higher scrutiny to the BZA’s Decision and Order
    than we do in usual zoning cases because, they say, the BZA’s findings and
    conclusions “largely mirror” the proposed order submitted by FSMB. We decline

    the invitation. Although we have cautioned against verbatim adoption of findings
    and conclusions proposed by one of the parties before an agency, 26 we do not
    “prohibit the practice.”27 That said, more heightened scrutiny may apply to a BZA
    (or any other agency) decision when our review of the record shows that the decision,
    relying substantially on the language of a proposed order, “on its face, fails to
    consider relevant evidence and fails to adequately explain its findings.” 28 Here,
    however, unlike our zoning decisions in Durant and Metropole, respectively, the
    BZA Decision and Order does not present “approximately 99.9% verbatim adoption
    of [FSMB’s] proposed order” without addressing petitioners’ objection; 29 nor does

    minor typographical changes.”30
    We do agree with petitioners that overreliance on verbatim submissions by a
    party for inclusion in a dispositive agency order may require heightened scrutiny of
    the agency decisional process, including its language. But, that concern must be
    folded into recognition that, in civil and agency proceedings, it is common – indeed,
    virtually routine – for the court or agency to require the parties to propose findings
    of fact and conclusions of law. These submissions usually offer significant help
    toward sharpening the decider’s focus and expediting achievement of a sound result
    within a time frame that otherwise would likely be intolerable, given the caseloads
    in judicial and administrative proceedings. The case law supports our deferential,
    not “heightened,” review here.
    In Watergate E. Comm. Against Hotel Conversion to Co-Op Apts. v. District
    of Columbia Zoning Comm’n, 31 for example, we applied our usual, deferential
    standard of review to affirm the Zoning Commission’s approval of a planned unit
    development, even though “the majority of the paragraphs” in the Commission’s

    findings and decision “were adopted verbatim from the applicant’s proposals.” 32 We
    observed that the Zoning Commission had “added sentences and phrases, changed
    sentence structure, referenced the applicable regulations, changed the grammar, and,
    in some places, added entirely new paragraphs.”33 Thus, we saw “no reason to doubt
    that the Commission’s findings and decision represent[ed] its own considered
    conclusions.”34
    Similarly, here, in scrutinizing FSMB’s proposed findings and conclusions,
    the BZA elucidated the issue of self-certification by citing a previous BZA decision
    on certification of the GFA requirement; added a reference to the letter from the new
    Colombian        Ambassador;   corrected   the   conditions   to   acknowledge   OP
    recommendations; and added a new section to address petitioners’ concern that the
    BZA had not accorded OP’s report “great weight.” We conclude, accordingly, that

    III. Special Exception
    A.      FSMB As a Nonprofit Organization
    The zoning regulations permit non-residential use of existing residential
    property by a “nonprofit organization” 35 in an R-3 zone, provided the user is granted
    a “special exception.” 36 Petitioners contend that FSMB, while concededly a
    § 501(c)(6) organization, is nonetheless a “lobbying” organization, not a “nonprofit
    organization” as defined in the zoning regulations,37 and thus it is not eligible for a
    special exception. They say, more specifically, that as a § 501(c)(6) “business
    league” – “organized” and “operated” for “the benefit of [its] members to promote
    the medical profession” – FSMB does not devote itself “exclusively” to benefiting
    35
    11 U DCMR § 203.1(n) (“Use of existing residential buildings and the land
    on which they are located by a nonprofit organization for the purposes of the
    nonprofit organization”).

    11 DCMR X § 901.2.
    37
    See supra note 5.
    20
    the public by pursuing a purpose specified in the zoning regulations that define a
    “nonprofit organization,” namely:
    An organization organized, registered with the appropriate
    authority of government, and operated exclusively for
    religious, charitable, literary, scientific, community, or
    educational purposes, or for the prevention of cruelty to
    children or animals; provided that no part of its net income
    inures to the benefit of any private shareholder or
    individual.[38]
    Petitioners made this argument at the first BZA hearing, as noted earlier,
    through their expert, Nancy Kuhn.        She testified that the zoning regulations’
    definition of a nonprofit organization is akin to, indeed manifestly drawn from, the
    exemption for purposes specified in § 501(c)(3),39 not from § 501(c)(6)40 exemption
    granted to FSMB. From this distinction, Ms. Kuhn drew two conclusions: (1) by
    promoting the “business interests of the physicians,” FSMB lacked a qualifying
    purpose based on the language defining “nonprofit organization”; and, in any event,
    (2) by promoting these business interests and receiving $40 million in revenue for
    38
    11 B DCMR § 100.2. (emphasis added); see text
    accompanying supra notes 3-5.
    39
    See supra note 12.
    40
    See supra note 14.
    21
    its “testing services,” FSMB violated the last clause of that definitional language
    precluding inurement of any net income “to the benefit of any private shareholder or
    individual.”41
    1.      FSMB’s “Purpose”
    We address, first, FSMB’s “purpose.” No evidence has been presented
    indicating that, given the similarities, the zoning regulation defining “nonprofit
    organization” was actually premised on, and thus limited by, § 501(c)(3).
    Furthermore, perhaps recognizing that FSMB was “organized exclusively for
    scientific and educational purposes,”42 Ms. Kuhn did not dispute that FSMB was
    “organized” for such tax-exempt purposes. She testified, however, that FSMB’s
    function as a “lobbying” organization (when coupled with its revenue from testing
    services and examination fees), revealed that it is not “operated exclusively” for its
    announced “scientific and educational purposes,” thus failing to qualify as a
    “nonprofit organization.” 43
    41
    See text accompanying supra note 38.
    42
    See supra note 2.
    43
    See text accompanying supra note 38.
    22
    FSMB disputes that analysis. In addition to citing the specific purposes stated
    in its articles of incorporation,44 FSMB called two witnesses at the first hearing to
    explain its activities in furtherance of those purposes. Its CEO, Dr. Humayun
    Chaudhry, and Senior Vice President for Legal Services, Eric Fish, both testified
    that: (1) FSMB is a federation of state governmental agencies;45 (2) the mission is
    educational; 46 (3) public health is a major focus; 47 and (4) FSMB operates an
    “Advocacy Office” in the District of Columbia to further its mission.48
    44
    See supra note 2.
    45
    “Our members are the 70 state medical and osteopathic boards that carry
    out the duties of state government in the regulation of medicine. Our members
    therefore are members of government” (Fish); “Typically, board members of each
    state and territory are appointed by the governor.” (Chaudhry).
    46
    “[W]e develop licensing exams that are related to medical education and
    the ability of medical students to be licensed for full unrestricted practice of
    medicine,” and FSMB hosts educational meetings for Board attorneys, as well as
    “webinars and round tables . . . open to the public in many cases” (Fish); “We have
    a work group looking at best practices to make sure that the state boards are
    streamlining their services,” and “[w]e are also educating medical students,
    residents, and physicians as well as the public about medical regulation” (Chaudhry).
    47
    FSMB helps the state boards “promote quality health care and protect the
    public” (Chaudhry); it “work[s] with our partners at the CDC, and the FDA” on
    “prescription drug monitoring programs” (Chaudhry); it partners “with the DEA to
    host multiple live conferences . . . to educate individual practitioners about opioid
    abuse” (Fish).
    48
    The office was established “to allow for regular meetings with members of
    Congress and the administration” about “state-based regulation, licensure,” or for
    creation of a “work group on regenerative and stem-cell therapies” at the request of
    a senator (Chaudhry).
    23
    Dr. Chaudhry and Mr. Fish both acknowledged that FSMB’s “Advocacy
    Office” on the Property could be characterized as a lobbying operation, and thus was
    registered as such under a Senate disclosure rule. Contrary, however, to petitioners’
    tax expert, Ms. Kuhn, Mr. Fish pointed out that FSMB’s “advocacy” – its lobbying
    – was but one percent of FSMB’s total budget, and thus was not substantial enough
    to threaten its tax exemption even if it were a § 501(c)(3) organization.
    Finally, Mr. Fish testified that, although FSMB was chartered as a scientific
    and educational nonprofit corporation, it also “carr[ies] out a charitable purpose,”
    namely, to “help our members fulfill [the] goal” of assisting “the functions of
    government” and “lessening of the burdens of government,” each of which
    “constitutes [a] charitable function under 501(c)(3) as well.”
    In sum, FSMB’s witnesses maintained that, as a § 501(c)(6) organization,
    FSMB satisfied the criteria for a “nonprofit organization,” entitled to apply for a
    special exception for the Property. But, they added, even if § 501(c)(3) criteria were
    24
    used to interpret the meaning of “nonprofit organization” 49 under the zoning
    regulations, FSMB would be eligible to apply for a special exception.50
    2. Inurement of Net Income to Benefit Private Members
    Petitioners further contend, based on Ms. Kuhn’s testimony, that FSMB
    cannot qualify as a “nonprofit organization” because, contrary to the zoning
    regulation defining a “nonprofit organization,”51 a substantial portion of net revenue
    – derived from grossing $40 million from its “testing services” – inures to the benefit
    of every “member,” the equivalent, she said, of profit to “a private shareholder or
    individual.” She illustrated her point by arguing that, if FSMB were to “spend
    49
    11 B DCMR § 100.2.
    50
    The BZA found that FSMB’s annual lobbying budget for activities on
    Leroy Place, N.W. is around $400,000 of approximately a $40 million budget
    nationally, or only one percent of its total activity – a de minimis use of its budget
    overall. Thus, argues FSMB, even if it were limited to the constraints imposed on a
    § 501(c)(3) exempt organization, it does not believe that FSMB’s advocacy would
    be “substantial in nature,” destroying its tax-exempt status. See Airlie Found. v.
    I.R.S., 
    283 F. Supp. 2d 58
    , 62-63 (D.D.C. 2003) (“operational test [of § 501(c)(3)]
    requires both that an organization engage ‘primarily’ in activities that accomplish its
    exempt purpose and that not more than an ‘insubstantial part of its activities’ further
    a non-exempt purpose” (citing Treas. Reg. (26 C.F.R.) § 1.501(c)(3)-1(c)(1)). We
    need not – and do not – opine on FSMB’s alleged qualification under § 501(c)(3).
    51
    See text accompanying supra note 35.
    25
    $400,000 on lobbying” (from its Advocacy Office on the Property), “that would
    actually dwarf the $170,000 of membership fees,” thereby suggesting that, if the
    special exception were granted, the members would personally reap $230,000, in
    violation of the applicable zoning regulation.
    Petitioners’ premise here is fallacious. Ms. Kuhn based her testimony on the
    assumption that an FSMB “member is a private shareholder or individual.” She later
    acknowledged, however, during the first hearing, that every FSMB “member” is a
    state medical board – a governmental entity – not a private individual. Her testimony
    therefore confused the actual benefits from FSMB membership – enhanced
    education and functioning of state medical boards – with the intangible reward an
    individual physician receives from test results generated by FSMB for a fee. That
    latter kind of benefit, akin to a medical school diploma, is far removed from a direct
    financial payback or “inurement” to a test-taker (or student) who pays for a service
    (or an education).
    3. BZA Ruling
    Based on the testimony and other evidence, the BZA was not impressed with
    petitioners’ argument that, because FSMB is a lobbying organization, it is
    26
    disqualified from the requested special exception. Rather, the BZA concluded that
    FSMB not only is “organized for educational and scientific purposes”52 but also is
    actually operated with two “primary missions” – “educational” and “charitable.”53
    In so concluding, the BZA specified that FSMB’s “regulation and improvement of
    the medical practice is undoubtedly a benefit to the public, as it lessens the burdens
    of government and certainly meets the definition of a charitable organization.” 54
    Therefore, the BZA rejected petitioners’ fundamental premise that, to operate with
    a charitable purpose, “an applicant for relief under Subtitle U § 203.1(n) does not
    have to be exclusively organized and operated as a 501(c)(3).” 55 The BZA ruled
    accordingly that, based on its dual purposes, “educational and charitable,” FSMB
    “qualifies as a nonprofit organization, as such term is defined under the Zoning
    Regulations.”56
    We must accord “great weight” to the BZA’s interpretation of the zoning
    regulations, and uphold its interpretation unless “plainly erroneous or inconsistent

    See supra note 2.

    27
    with the regulations.” 57 We perceive no such error or inconsistency here and
    therefore must sustain the BZA’s ruling that FSMB is a “nonprofit organization”
    qualified to apply for the special exception it seeks.
    B.      Effects on Use of Neighboring Properties
    We turn to the merits. Petitioners claim BZA error regarding two “specific
    special exception requirements”58 in finding that: (1) FSMB’s use of the Property
    will not “adversely affect the use of the neighboring properties,” 59 and further
    finding that (2) the “amount and arrangement of parking spaces” will “be adequate
    and located to minimize traffic impact on the adjacent neighborhood.” 60 Cutting
    across these specific requirements are issues of “undue adverse impact” 61 and

    58
    Decision and Order at 9. As the BZA acknowledges, id. at 17, 21, the first
    “specific special exception” requirement quoted above is virtually the same as the
    second “general special exception” requirement, 11 DCMR X § 901.2. (b). See text
    accompanying supra notes 7 and 8.

    insufficient mitigation “to protect adjacent or nearby property.” 62 We consider first
    the anticipated effects on the “use of the neighboring properties.”
    1. Adverse Effects
    As to the alleged adverse “effects” or “impact” on neighboring properties, the
    BZA concluded that petitioners’ evidence did not “support the claim” that FSMB’s
    use of the Property “would be more adverse” – “more intense” – than its previous
    use “as a chancery,”63 which the Colombian government had operated until October
    2015.64 Petitioners offered sworn testimony claiming such intensified impact, based
    on “observations by neighbors” that a “large exodus” of chancery personnel had
    begun in 2007, leaving a “skeleton staff” in 2014. 65 To the contrary, FSMB
    “provided evidence of events held [by the Colombian Government] at the Property,
    including visits from senior government officials and press conferences, as recently
    as 2014.”66 Furthermore, a letter from the Colombian Ambassador stated that the

    29
    “Government of Colombia used the property as a functional Embassy with
    approximately 25-40 full time diplomats, administrative assistants and military
    personnel” until 2015. Significantly, added the BZA, the Colombian government
    did so without “any conditions or limits placed on its use.”67 Petitioners objected to
    any reliance on the Ambassador’s letter because he was not appointed until 2017 and
    therefore “had no personal knowledge of the number of employees at the Chancery
    in October 2015.” It is not obvious, however, that an Ambassador, submitting a
    letter for an official proceeding, would not have access to such information for that
    letter about his former chancery, and petitioners proffered no contrary evidence. We
    therefore must agree, as FSMB puts it, that the BZA could accord the Ambassador’s
    letter “a modicum of deference, especially as it relates to prior government use.”
    Importantly as well, although the BZA “believ[ed] the testimony and
    observations from neighbors were genuine” – meaning, we think, were offered in
    good faith – the BZA ultimately rejected the neighbors’ observations that the
    chancery had been “vacant for over a decade.”68 It concluded, based on all the
    evidence – the Ambassador’s letter showing 25-40 employees until 2015 and the
    67
    Id. at 24.
    68
    Id.
    30
    chancery events through 2014, as well as the neighbors’ observations to the contrary
    – that it was “possible” the chancery had “operated with moderate-heavy office use
    without much impact on the community.”69
    Ultimately, therefore, the BZA concluded that the record did not “support the
    claim that use by the FSMB would be more adverse” to neighboring properties “than
    the use of the property as a chancellery.”70
    2. Mitigating Conditions
    The BZA reached the foregoing conclusion, in part, by elaborating conditions
    that mitigated the adverse impact on the neighborhood. It observed that FSMB, with
    “only 70 members” nationally, is proposing an “extremely limited,” not “intense”
    office use.71 Unlike the chancery use, moreover, the BZA found that FSMB will be
    reducing adverse impact on the neighborhood through compliance with numerous
    conditions that limit the number of people working on site, the number of committee
    meetings and participants there per quarter, and the number of invitees to an annual
    69

    31
    reception on the Property (ending no later than 8 p.m.). Also, employee and visitor
    parking on Leroy Place, N.W. will be forbidden, and sundry other limitations will
    be imposed governing visitors, weekend guests, and deliveries; adding security
    lighting; and establishing a liaison with Advisory Neighborhood Commission
    (“ANC”) 2-D.72
    Petitioners nonetheless argue for reversal by alleging that, as to the mitigating
    conditions, the BZA failed to give the required “great weight” to OP’s
    recommendations,73 and erred in particular by failing to explain why it “increased
    [the] number of people permitted on site and at events” over the numbers OP had
    proposed.
    We therefore turn to the facts (which challenge easy reading). In its report,
    OP recommended that the BZA grant the special exception, subject to “adequate
    operational controls and mitigation measures” 74 to reduce adverse effects on the
    neighborhood from activities on the Property. To that end, OP recommended
    72
    See supra note 19 and accompanying text.
    73
    
    D.C. Code § 6-623.04
     (2018 Repl.) (requiring the BZA to give “great
    weight to the recommendation of the Office of Planning”).

    32
    (among other conditions): permitting a “maximum of 15 people” to “work on site”;
    limiting FSMB to “three (3) committee meetings per quarter during business hours,”
    attended by not more than “15 invitees per meeting” (one of which per quarter “may
    include a reception . . . that will end by 8 p.m.”); and requiring “[a]nnual meeting[s]
    and events” to be “held off site.”75
    The BZA “carefully considered the OP report” and found “its
    recommendation to grant the application persuasive.” 76 That said, with a decision
    falling in between the FSMB and OP proposals, 77 the BZA did not accept in full the
    specific conditions limiting OP’s approval. Rather, the BZA approved: (1)] a
    “maximum of 18 [not OP’s 15] people [to] work on site”; 78 and (2) a “maximum of
    three committee meetings per quarter,” limited to “25 [not OP’s 15] invitees per
    75
    In its Pre-Hearing Statement in Support of Special Exception Relief, FSMB
    proposed to limit: (1) its staff on the Property to 15 to 25, and (2) its on-site
    receptions to “once a quarter,” not to exceed 50 guests, ending “by 8:00 p.m.” At
    the first public hearing, FSMB added a request for “two to three meetings a quarter,”
    with average attendance of “8 to 15.” At the second hearing, FSMB upped the likely
    average number of attendees for those committee meetings to “about 15 to 20.” By
    the time of proposing its findings of facts and conclusions of law, however, FSMB
    had asked to add more attendees to those meetings: “a maximum of three (3)
    committee meetings per quarter, not to exceed more than 25 invitees per meeting.”

    33
    meeting”; then added (3) a “maximum of one reception per year”79 (not one per
    quarter), to be “held the night before a committee meeting,” restricted to 50 guests
    and ending “by 8:00 p.m.” (not the 15-guest limitation recommended by OP for a
    quarterly reception). 80 BZA also (4) required (as FSMB and OP agreed) that
    “[a]nnual meeting[s] and events shall be held off site” 81 (presumably, though not
    definitively, excluding the annual reception on the night before a committee
    meeting).
    In sum, after considering the reduced on-site activity recommended by OP,
    the BZA did not go that far. To OP’s proposed limitations, the BZA: [1] added
    three potential staff members, [2] added ten more attendees at each committee
    meeting (three per quarter), and [3] added 35 more guests (totaling 50) for an annual
    reception, in contrast with the 15-maximum number of guests that OP had
    recommended for quarterly receptions (which the BZA altogether rejected).

    correction we assume the BZA will make.

    3.    “Great Weight”
    In response to the BZA’s modifications of OP’s recommendations, petitioners
    argue that the BZA was required to make “a finding of fact on each material
    contested issue of fact”; 82 that the permissible levels of people and events on the
    Property if a special exception was granted are a material contested issue; that OP’s
    recommendations in this regard must be accorded “great weight”;83 and that the BZA
    failed to make the findings necessary to justify its departures from OP’s
    recommendations. We agree with petitioners that, on this record, the contested
    levels of people and events on the Property collectively present a material issue that
    requires sufficient findings supported by substantial evidence. That brings us to the
    “great weight” statute.84
    The BZA ultimately found (essentially a conclusion of law) that, “with
    adequate controls and conditions, the limited office use proposed – of up to 20
    [reduced to 18] employees who walk to the office, and a handful of meetings – would

    35
    not adversely affect the use of neighboring properties.”85 The issue, then, is whether,
    in reaching that quite general conclusion, the BZA gave the required “great weight”
    to OP’s three specific recommendations at issue here.
    Petitioners do not dispute that the BZA accepted OP’s recommendations that
    the number of people working on site and attending committee meetings must be
    reduced below the levels requested by FSMB. 86 Nor do they dispute that the BZA
    moved considerably toward OP in capping the number of people on site during
    business hours: 18 rather than the 25 sought by FSMB (though three higher than the
    15 daily level recommended by OP).          Nonetheless, [1] the staffing level was
    vigorously contested, as were [2] BZA’s approvals of 25 attendees at committee
    meetings during business hours (compared to OP’s suggested 15), and [3] BZA’s
    approvals of 50 attendees at an annual reception (rather than OP’s recommended
    quarterly receptions limited to 15 guests). 87 Therefore, in addressing the “great
    weight” issue, we will determine whether the BZA must reappraise those three
    differences and, if so, the extent to which the BZA must document its reasoning.

    FSMB withdrew its initial request for quarterly receptions, approved by
    OP, perhaps (though we do not know) in the hope of gaining BZA permission for
    the annual 50-guest reception, which it received.
    36
    This court first reviewed a “great weight” requirement to determine the level
    – and required articulation – of the deference owed to an ANC recommendation in
    an Alcohol Beverage Control Board proceeding. 88 Since then, this court has
    routinely applied the “great weight” analysis to ANC “issues and concerns” in BZA
    proceedings as well.89 Eventually, a “great weight” requirement was added to the
    Office of Zoning Independence Act of 1990, requiring the BZA “to give great weight
    to OP recommendations.”90 In fact, even before the “great weight” requirement was
    incorporated into the zoning legislation, this court had said that the BZA “is required
    to demonstrate in its findings that it considered OP’s views, and must provide a
    reasoned basis for any disagreement with them.” 91 In coming to that conclusion, we

    drew upon Kopff     92
    (addressing ANC concerns) for interpretation of the BZA’s
    obligation to “give great weight” to OP recommendations.93
    Here, we conclude that, in its Decision and Order, “[t]he BZA should have
    explicitly acknowledged and addressed OP’s reservations.”94 In other words, we
    agree with petitioners’ contention that, in making the three material changes from
    OP’s positions, the BZA’s Decision and Order did not articulate a “reasoned basis”
    for the disagreements, 95 let alone “elaborate, with precision, its responses to the
    [OP’s] issues and concerns” 96 that nonetheless led to the BZA’s higher numbers.
    More specifically, the BZA Decision and Order itself did not address the disparity
    between its permitted “18 people” working in the Property and OP’s recommended

    limitation of the number to 15.97 Nor did that final ruling discuss BZA’s permission
    for FSMB to hold an annual reception with 50 guests, as compared with OP’s
    willingness to approve three quarterly receptions if limited to 15 guests98 (implying
    that OP’s principal concern was the number of attendees at any reception).99 Finally,
    97
    At the final public meeting on April 18, 2018, BZA members observed that,
    initially, FSMB had proposed a staffing level on the property limited to 15 but, over
    time, had come to request 25 employees. See supra note 75. The Chairperson
    initially favored 15 employees because FSMB had “once said 15 was appropriate.”
    Another member, saying that the “difference between 15 and 20 isn’t that
    significant,” was “quite comfortable” with a “limit of 20,” acknowledging that it
    would be too “challenging” to limit five of the employees to “temporary” ones, as
    FSMB apparently had proposed in an effort to reach at least 20. Another member,
    who “could go either way because the building is so large,” further observed that
    “OP also weighed in and recommended the 15 number. So I was kind of stuck on
    15[,] but I’ll see what my other fellow Board members have to say about it.” Still
    another member, without “a strong feeling on 15 or 20,” picked 20. The Chairperson
    replied, “[W]e’re splitting hairs”; acknowledged his belief that FSMB would “live
    with 15” and “do the project”; then added, “I don’t mind 18” – after which, with
    apparent agreement on 18, the discussion moved on.
    98
    The Decision and Order, at 27, actually approved one reception per quarter
    with up to 50 guests, which the parties agree was a mistake that would be “mended”
    to authorize only one, annual, 50-guest reception. See supra note 79.
    99
    Also at the final public meeting on April 18, 2018, BZA members paid
    considerable attention to “the receptions and the meetings,” eventually appearing to
    settle for an annual FSMB reception on the Property with 50 guests as less adverse
    in its impact on the neighborhood than the quarterly receptions limited to 15 guests
    recommended by OP – a choice described by one BZA member as a “splitting hair
    type of situation.” Of particular concern as well were “traffic impacts” along a
    “narrow one-way street with the valet parking and all that.” Then, once the BZA
    members rejected OP’s proposed quarterly receptions limited to 15 guests, they
    moved on to consider the number attending committee meetings and expressly
    jumped, without explanation, to change “the OP condition” from “15 to 25.” Also
    39
    BZA’s Decision and Order omitted discussion of its condition limiting committee
    meetings to 25 participants rather than OP’s recommended 15.
    The BZA concluded, overall, that petitioners had “provided no evidence” that
    FSMB’s proposed use “would be more adverse than the [previous] use of the
    property as a chancellery,”100 the fundamental comparison critical to approval of the
    special exception. The BZA reached that conclusion (as noted earlier) because of
    the “adequate controls and conditions” imposed:        “up to 20 [reduced to 18]
    employees who walk to the office, and a handful of meetings.” 101 In reaching that
    generalized conclusion, the BZA gave no “reasoned basis” 102 for rejecting OP’s
    recommendations, directed at assuring that FSMB’s use of the Property would “not
    adversely affect the use of the neighboring properties.”103 In failing to “elaborate,
    with precision, its response to the [OP’s] issues and concerns” 104 about the number
    without explanation, they accepted FSMB’s proposal for an annual reception on site
    “with 50 people.”

    of employees and the sizes of meetings and receptions on the Property, the BZA
    failed to accord OP’s recommendations the “great weight” required by statute.
    4.     Harmless Error?
    There remains, however, the question whether the BZA’s erroneous failure to
    “give great weight” in its decisional analysis to OP’s recommendations is harmless,
    in light of (1) the members’ discussions at the end of the public hearings and to (2)
    all the other express conditions imposed on the special exception beyond those
    limiting staff, hours of operation, meetings, and receptions on the Property. 105 We
    believe not.
    As to the first, BZA discussion-based argument, it is clear that the BZA
    addressed in detail petitioners’ issues and concerns about the effects on the
    neighborhood of various levels proposed for staffing the Property, committee
    meetings, and receptions. 106 Moreover, the BZA members were aware of OP’s
    recommendation as to each. On the other hand, aside from the special concern for
    not burdening the neighborhood with many, bothersome receptions, the BZA
    105
    See text accompanying supra notes 9 and 21.
    106
    See supra notes 97 and 99.
    41
    discussions of these matters appeared to perceive immaterial – “splitting hair” –
    differences between OP and the BZA. We do not say that the BZA abused its
    discretion in choosing the options it selected. We do say, however, that even – or
    perhaps especially – when the decision becomes a virtual coin flip, the members’
    reasoning that culminates in the final, written decision must reflect “great weight”
    given to OP’s issues and concerns. The BZA’s final discussions reflected the
    members’ thinking – their reasoning back and forth – from which one might distill
    various levels of attention to OP recommendations. But, until the decision is written,
    we cannot be sure that the required “great weight” has been figured in.
    Second, it is true that several other conditions imposed by the BZA’s Decision
    and Order offer a level of protection to the neighborhood comparable in importance
    to those that concerned OP – for example, the conditions prohibiting staff and visitor
    parking on LeRoy Place, N.W. during business hours, or on evenings, 107 as well as
    those preventing rentals and fundraisers on the Property. 108 These other significant
    107
    See text accompanying supra note 21.
    108
    See supra note 21.
    42
    conditions, however, when combined with the other, lesser conditions imposed,109
    do not significantly dilute the impacts from allegedly excessive activity on the
    Property. Thus, the differences between OP’s recommendations and the BZA’s
    conditions are not inconsequential; the BZA’s failure to “give great weight” to OP’s
    recommendations cannot be called harmless error. 110
    5.    Remand
    We therefore must remand the case for the BZA to address these matters with
    the required specificity. In remanding, however, we are not reversing the grant of a
    special exception for the Property. The BZA’s Decision and Order was based, in
    part, on personnel and attendance levels greater than OP would have allowed; thus,
    109
    We refer here to conditions governing loading, deliveries, security
    lighting, bicycles, liaison with ANC 2-D, and smoking. See supra note 21 and
    accompanying text.
    110
    On one occasion we held harmless the BZA’s failure to give great weight
    to OP’s “expressed reservations regarding the placement of the new law school” at
    American University. See Glenbrook Rd. Ass’n, 
    605 A.2d at 34, 36
    . We did so,
    however, not because OP’s reservations were insignificant but, rather, because the
    BZA “sufficiently addressed ANC 3-E’s concerns, [which] largely adopted OP’s
    objections.” 
    Id. at 36
    .
    43
    there is no reason to believe that adoption of OP’s lesser levels would necessarily
    change the present outcome, absent some other reason for reversal. 111
    C. Adequacy of Amount and Arrangement of
    Parking Spaces
    Petitioners challenge the BZA’s finding that the “amount and arrangement of
    parking spaces is adequate and located to minimize traffic impact on the adjacent
    111
    Petitioners also claim BZA error “in concluding no adverse impacts in
    residential home prices and removal of the [P]roperty from residential use.” As to
    neighborhood home prices, the BZA found that the testimony was conflicting, and
    thus inconclusive, between witnesses who anticipated increased tax assessments and
    those who foresaw decreasing residential values attributable to a special exception
    for FSMB. Decision and Order at 25. As to the alleged adverse impact on the
    residential nature of the neighborhood, petitioners rely primarily on testimony from
    their land use expert, Ellen McCarthy, who testified rather speculatively that “the
    major adverse impact” on the neighborhood from FSMB’s special exception would
    be “destabilizing of the residential real estate market,” putting a “quick stop” to a
    recent trend in the area toward restoring “formerly non-residential” buildings “back
    into homes.” The BZA found, however, that other evidence proffered by petitioners
    themselves showed that the Property “can be easily converted back to residential”
    use – indeed, that “at least a dozen properties that were previously non-residential
    were converted back to residential use.” 
    Id.
     Accordingly, the BZA found that “there
    is no evidence to prove” (meaning the evidence was insufficient to prove) that this
    Property “will be permanently removed from residential use.” 
    Id.
     In sum, the BZA
    ultimately concluded that the “alleged concerns related to property values and the
    residential market are general and do not adversely affect the use of neighboring
    properties as residential properties.” 
    Id.
     These findings and conclusions are
    supported by substantial evidence and the law.
    44
    neighborhood,” 112 in satisfaction of the fourth enumerated “specific special
    exception” requirement. 113 We cannot agree with petitioners; substantial evidence
    supports that ultimate finding (a conclusion of law),114 which is far from arbitrary,
    capricious, an abuse of discretion, or otherwise unlawful. As noted above in part
    I(C), a condition on the proposed special exception bars anyone associated with
    FSMB, staff or visitor, from parking on Leroy Street, N.W. Moreover, the BZA
    found that the Property is located “about 500 feet from Connecticut Avenue bus
    stops, .4 miles from Massachusetts Avenue bus stops, and .4 miles from the DuPont
    Circle Metro entrance.” 115 There is also “a public parking garage about .2 miles
    from the Property,” and “the Washington Hilton garage is .1 miles” away. 116
    Petitioners downplay those conveniences, expressing concern about “traffic back-
    ups” from delivery trucks, taxis, and other ride-sharing vehicles on narrow, one-way
    Leroy Place, N.W. and its alley – concerns anticipating “larger meetings” and
    “nighttime events” on the Property. These concerns, however, overlook the express

    p.m. There is no evidence of sustained, large-scale arrivals and departures at the
    Property. Furthermore, reports from OP and DOT support the BZA’s finding that
    “the amount and arrangement of parking will have minimal traffic impact on the
    adjacent neighborhood,” as the “proposed nonprofit office use is a use that is
    inherently quiet and generates little traffic.”117 That finding is buttressed by the
    further finding that “many office employees currently utilize public transportation”
    and, if driving, “will be directed to park in [the nearby] parking garages.”118 It is
    true, as petitioners point out, that in supporting its finding that FSMB generates
    “little traffic,” the BZA mentioned, among the other reasons, that FSMB has “only
    eight full-time employees” 119 whereas the condition limiting the number of
    employees permits up to eighteen. That potential increase, however, is insufficient

    to undermine the BZA’s reliance on substantial evidence that, given the
    aforementioned safeguards, “specific special exception” number 4 is satisfied. 120
    D.      Variance re Gross Floor Area
    To satisfy “specific special exception” requirement number 2, the “gross floor
    area of the building in question, not including other buildings on the lot, [must be]
    ten thousand square feet (10,000 sq. ft.) or greater.”121 FSMB’s initial application
    requested not only a special exception but also an area variance from the GFA
    requirement. FSMB later discovered, however, that it had omitted, partially, the
    GFA of the lower level from its calculation. It submitted the revised calculation to
    the BZA, “certifying”122 the GFA at 10,825 square feet, supported by a letter and
    topographic survey from an engineering firm.          At the first public hearing, a

    121
    11 DCMR U § 203.1(n) (2).
    122
    In its Decision and Order at 9, the BZA observed that “[c]ontrary to
    FSMB’s contention, proof that . . . the minimum GFA exists cannot be self-certified.
    Self-certification is only that the relief is needed, not that the Applicant and the
    property fall within the requirements for the relief to be granted.” See 11 DCMR Y
    § 300.6(b)(3) (a certified architect certifies that “the relief requested is required in
    order for the proposed structure to be erected or the proposed use to be established.”).
    47
    representative from OP testified that the GFA requirement for a special exception
    had been met, obviating any need for an area variance.
    Petitioners challenged that testimony by submitting, prior to the second public
    hearing, its own expert’s architectural report which concluded that the building has
    only 9,002 GFA. They also noted that, in light of the conflicting analyses, an expert
    of their choosing should have been permitted to measure the house – particularly the
    lower level area contested by petitioners’ expert. The BZA rebuffed petitioners’
    challenge on three grounds: First, the BZA gave credence to the OP assessment that
    the Property satisfied the GFA requirement. Second, the BZA relied on evidence
    submitted by petitioners themselves. In order to show how many residences in the
    Sheridan-Kalorama Historic District could apply for special exceptions for non-
    residential use if FSMB’s application were granted – triggering a trend that could
    further affect the area adversely – petitioners proffered a list of residential properties
    exceeding 10,000 square feet, compiled by searching the so-called “PIVS system.”
    The BZA found 2118 Leroy Place, N.W. among those properties, reinforcing
    FSMB’s claim to a variance exception. 123 Finally, the BZA observed – without
    123
    Decision and Order at 16.
    48
    contradiction – that the Zoning Administrator (“ZA”), an officer of DCRA,124 would
    have the final say on the GFA issue (including the related building permit), subject
    to petitioners’ right “to challenge the eventual GFA determination.” 125 Concluded
    the BZA: “[I]t is certainly plausible that the Zoning Administrator would find that
    the Building has a Gross Floor Area in excess of the 10,000 square foot GFA
    requirement,” and thus “it is appropriate for [BZA] to accept the Applicant’s self-
    certification.”126
    Absent any legal challenge by petitioners at the agency level contending that
    the ZA had to definitively validate the Property’s 10,000 square foot (or greater)

    Id. The BZA’s statement here – that it was “appropriate . . . to accept
    [FSMB’s] self-certification” – appears at odds with its earlier statement on page 9
    of the Decision and Order that self-certification means only that relief from a
    variance “is needed.” Nonetheless, given everyone’s agreement that the ZA must
    be satisfied before the BZA can definitively approve a special exception without a
    variance, we perceive no meaningful inconsistency in the BZA’s granting
    conditional, rather than definitive, approval of FSMB’s application for special
    exception – as occurred here, when the BZA clearly stated that, in “accepting
    Applicant’s self-certification” it was “defer[ring] to the eventual determination of
    the Zoning Administrator on this point.” Id. at 16.
    49
    GFA before ruling on the application for special exception, 127 the BZA accepted
    FSMB’s proffered compliance as prima facie evidence of compliance (“it is certainly
    plausible”), subject to the ZA’s confirmation as a condition subsequent. 128
    IV. Conclusion
    Based on a thorough review of the record, including the BZA’s 27-page
    Decision and Order, the parties’ briefs, and the entire transcripts and record,
    including exhibits, from the two public hearings before the BZA, and after applying
    the standards for reviewing a BZA proceeding, we remand the case for further
    proceedings for the BZA to give “great weight,” consistent with this opinion, to the
    recommendations of the Office of Planning with respect to FSMB’s staffing,
    meetings, and receptions.
