The regulations set forth in this article or elsewhere in this chapter are the regulations in the R-SF Single-Family Residential District. The purpose of this district is to provide for single-family residential development of spacious character, together with such public buildings, schools, churches, public recreational facilities and accessory uses as may be necessary or are normally compatible with residential surroundings. This district is located to protect existing development of high character and contains vacant land considered appropriate for such development in the future.
No building or premises shall be erected, structurally altered, enlarged or maintained nor shall any land be used, except for the following purposes:
Single-family dwellings, detached.
Temporary buildings, the uses of which are incidental to construction operations or sales of lots during development being conducted on the same or an adjoining tract or subdivision and which shall be removed upon completion or abandonment of such construction or upon the expiration of a period of two years from the time of erection of such temporary buildings, whichever is the sooner.
Accessory buildings and uses, provided that such accessory buildings are not used for housekeeping purposes.
Religious institutions, including churches, parish halls, temples, convents and monasteries.
The following uses of land and buildings within the R-SF District shall be allowed only by special exception to this chapter, granted only by the Board of Zoning Appeals. Standards and procedures for special exceptions are contained in Article XVII.

Any pumps and filters which are located above ground shall be at least 50 feet from abutting properties.
All lights shall be shielded to reflect or direct light away from adjoining property.
The required off-street parking space shall be computed on the basis of one space for each 5,000 square feet of park area.

No cooking facilities shall be allowed in the guestrooms.
