Petition for Review of a Decision of the District of Columbia Board of Zoning Adjustment
On April 15, 1998, the Board of Zoning Adjustment (BZA) held a public hearing and granted the application of intervenor Richard T. Ross for a special exception to operate Swann House Bed and Breakfast as a home occupation with nine guest rooms and two full-time non-resident employees. The application was supported by Advisory Neighborhood Commission 1C and a large number of neighborhood residents, including the abutting neighbors of Swann House. The application was opposed, however, by several neighborhood residents, including petitioner Israel Stollman. It was also opposed by petitioner Dupont Circle Citizens Association (DCCA), a civic association some of whose members reside within the vicinity of Swann House. Their petition for review in this court principally challenges the BZA's interpretation of the Zoning Regulations to permit a bed and breakfast to host a limited number of guest-sponsored social events as a so-called "accessory use." We uphold the BZA's interpretation and accordingly affirm its order granting the application for a special exception.
Swann House is a large "Romanesque Revival" mansion constructed between 1883 and 1910. The house is located at 1808 New Hampshire Avenue, N.W., between Swann and S Streets, and has been certified by the State Historic Preservation Officer of the District of Columbia as a historic building which contributes to the character of the Dupont Circle Historic District. The neighborhood surrounding Swann House is zoned D/R-5-B, a moderate density designation permitting the widest range of urban residential development and compatible institutional and semi-public buildings, as well as diplomatic chanceries. See 11 DCMR §§ 350, 1001 (1995). The uses in the immediate vicinity include an embassy, fraternities and sororities, apartment buildings, hotels, private clubs and non-profit organizations, and rowhouses with either single- or multi-family occupancies.
Ross and his wife Mary L. Ross occupy Swann House as their principal residence. The house formerly was used as a rental apartment building. In 1996, the Department of Consumer and Regulatory Affairs (DCRA) issued Ross a home occupation permit to operate a bed and breakfast at Swann House. Questions arose, however, as to whether the DCRA had issued the permit in error, and Ross applied for a new permit in early 1998. This time the Acting Zoning Administrator of DCRA denied the application on the ground that certain requirements of the regulations governing home occupations were not met, and Ross therefore would have to apply to the BZA for a special exception pursuant to 11 DCMR §§ 3108.1 *fn1 and 203.10. *fn2 The Rosses applied for such a special exception on February 17, 1998.
The Zoning Regulations set forth the requirements for home occupations in 11 DCMR § 203, and for home-based bed and breakfast operations specifically in subsection 203.8. Ross requested relief from only two of those requirements, a limitation on the maximum number of guest bedrooms *fn3 and a limitation on the number of non-resident employees. *fn4 The BZA found that this relief would be appropriate in view of the character of Swann House and the surrounding district and the needs of the bed and breakfast business, that it would not compromise the general purpose and intent of the Zoning Regulations, and that it could be granted without adverse impact on the neighborhood.
The heart of the controversy before the BZA concerned the Rosses' stated intention to permit registered guests to hold "small private social gatherings," such as weddings and other family celebrations, as part of the operation of the bed and breakfast. The Zoning Regulations do not address expressly the propriety of social events held at bed and breakfasts or, for that matter, at other uses permitted in residential districts (such as, for example, embassies, boarding houses, fraternities and sororities, private clubs, museums, churches and schools). The Rosses presented testimonial and documentary evidence that it is customary for bed and breakfasts to host social functions arranged by their guests as an incident of the business, and they offered to limit the number of such events to twenty-four a year and no more than five in any one month. They argued, and the BZA agreed, that this number of such guest-sponsored activities would be "customarily incidental and subordinate to" the bed and breakfast use, and thus permitted as an "accessory use." The term "use, accessory" is defined in 11 DCMR § 199.1 to mean "a use customarily incidental and subordinate to the principal use, and located on the same lot with the principal use." As discussed infra, accessory uses not otherwise expressly authorized by the Zoning Regulations are permitted in residentially zoned districts, in accordance with 11 DCMR § 202.10.
In addition to the limit on the number of guest-sponsored social events held at Swann House, the Rosses offered to agree to other conditions to meet neighbors' concerns about noise, parking and traffic problems that might be caused by social events at Swann House. With these limitations and conditions, the BZA found that the Rosses had satisfied their burden of proof and granted the Rosses a special exception to operate a bed and breakfast at Swann House. *fn5
Petitioners challenge the BZA's predicate finding that hosting a limited number of guest-sponsored social events a year is permitted as an accessory use to the bed and breakfast use. Quoting the definition of an "accessory use" in 11 DCMR § 199.1, petitioners argue that a permissible accessory use must be customarily incidental and subordinate to the "principal use." Under the Zoning Regulations, however, home occupations such as bed and breakfasts are considered accessory uses; the principal use is deemed to be the residential use. See 11 DCMR § 203.1. Indeed, it was conceded, and the BZA found, that Swann House is "principally" used as the Rosses' residence and that the bed and breakfast use is "secondary." Therefore, petitioners reason, since the bed and breakfast use is only an accessory use and not the principal use, hosting guest-sponsored social events cannot be permitted as an accessory use to that use. Rather, petitioners contend, offering such "hospitality services" (as petitioners characterize them) constitutes in reality a second "home occupation." Petitioners argue that this second home occupation is impermissible because it is neither permitted expressly by the Zoning Regulations (as the bed and breakfast use is) nor "customarily incidental" to the principal, residential use of Swann House. Additionally, petitioners argue that, viewed as subject to the home occupation regulations rather than as a permitted accessory use, hosting social functions for guests would contravene several specific zoning provisions from which the Rosses have not been granted a waiver. *fn6 Moreover, petitioners add, to procure such a waiver the Rosses would have to apply for a variance, which is more difficult to obtain than a special exception. *fn7
The crux of the matter is thus whether the BZA reasonably interpreted the Zoning Regulations as permitting accessory uses to other accessory uses. "When the BZA's decision turns on its interpretation of a regulation that agency is charged with implementing, that interpretation must be upheld unless it is `plainly erroneous or inconsistent with the regulation.'" Levy v. District of Columbia Bd. of Zoning Adjustment, 570 A.2d 739, 746 (D.C. 1990) (quoting George Washington Univ. v. District of Columbia Bd. of Zoning Adjustment, 429 A.2d 1342, 1348 (D.C. 1981)). Petitioners' argument, predicated on a narrow reading of the definition of an accessory use contained in 11 DCMR § 199.1, is at first blush plausible. However the argument is undercut by the way that the term "accessory use" is actually employed in the Zoning Regulations. As the term is actually used, it supports the reasonableness of the BZA's interpretation.
Chapter 2 of Title 11 of the DCMR contains the regulations governing R-1 Residence District Use. Uses permitted as a matter of right, which include residential uses, are enumerated principally in 11 DCMR § 201. Section 202, entitled "Accessory Uses (R-1)," then lists in subsections 202.2 through 202.9 a series of specific uses which "shall be permitted as accessory uses in an R-1 district incidental to the uses permitted in this chapter." *fn8 Included in this listing are home occupations "as provided in and subject to § 203" (which includes bed and breakfasts, see § 203.8). *fn9 11 DCMR § 202.8. Notably, after listing these specifically identified, permitted accessory uses, § 202 states:
202.10 Other accessory uses customarily incidental to the uses permitted in R-1 Districts under the provisions of this section, including mechanical amusement machines that are accessory to uses specified in § 210, shall be permitted, subject to the provisions of § 2501. (emphasis added). *fn10
Since the uses permitted "under the provisions of this section," i.e., under § 202, are exclusively accessory uses, the natural reading of § 202.10 is that accessory uses customarily incidental to the specifically permitted accessory uses (including bed and breakfasts) shall be permitted. This conclusion holds even if the word "section" is construed broadly to encompass not only § 202 but also other sections in Chapter 2 of 11 DCMR. On the other hand, it is difficult to read the words "this section" in § 202.10 so as to exclude § 202, which is how they ...
