The use of land structures shall be limited to only the primary and accessory uses permitted in each zoning district, unless specifically permitted, exempted, or otherwise modified by this or other sections of this chapter. In addition to the regulations stipulated for each use elsewhere in this chapter, the following use regulations shall apply:
A. Primary uses. In the Conservation/Agricultural and Residential Districts, no more than one primary use shall be permitted on any single lot of record. In all other zoning districts, there may be more than one primary use, but each additional primary use must conform to the lot, yard setback, maximum height and all other regulations contained herein.
B. Accessory uses. All accessory structures, except where otherwise permitted by this chapter, shall comply with the lot, yard setback, and maximum height requirements for the primary use to which it is necessary. Accessory uses and structures may include, but are not limited to, the following:
(1) All single-family detached dwellings may include one one-bedroom apartment, provided that:
(a) Such is part of the dwelling;
(b) The total floor area of the apartment does not exceed 500 square feet;
(c) One additional off-street parking space is provided; and
(d) No more than two persons occupy the apartment.
(2) All commercial buildings permitted in the C-1 District may include one dwelling unit.
(3) Industrial uses may include a retail factory outlet for the sale of those products produced on the premises, provided that the floor area of such outlet does not exceed 25% of the total floor area of the primary structure, or, if there is more than one use in the primary structure, 25% of the particular use. Wholesale distribution use may include retail sales to the general public as an accessory use only if the total accessory uses do not exceed 25% of the total floor area of the use. Any such retail outlet must comply with the parking requirements.
(4) Outdoor pools, including swimming pools, hot tubs, water gardens and spas, are permitted as accessory structures in any district, provided that outdoor pools capable of containing water 18 inches or more in depth shall meet the following requirements:
(a) No outdoor pools may be located in any front or side yard setback area, but may be located in the rear yard setback area, provided that no part of the pool, excluding paved areas, accessory structures and fencing, shall be located within 20 feet of rear property line, nor from the side lot line of a distance equivalent to the side yard setback for an accessory structure within the applicable district.
(b) All outdoor swimming pools below ground level shall be completely surrounded by a permanently anchored fence or wall not less than four feet in height, which shall be so constructed as not to have openings, holes, or gaps larger than four inches in either height or width. Should the wall of the pool be above ground, the required fence or wall may be securely affixed to the top of the pool wall so that the total height of the wall of the pool and the fence or wall shall be not less than four feet.
(c) All gates or doors opening through such required fence or wall shall be equipped with a self-closing and self-latching device capable of being locked for keeping the gate or door securely closed at all times when not in use.
(d) Lights used to illuminate any swimming pool shall be so arranged and shaded so as to reflect light away from adjoining premises; and not become a nuisance or annoyance to adjacent property owners.
(5) Small accessory buildings of not more than 144 square feet in ground floor area and not more than 10 feet in height are permitted in the side and rear yard setback areas, provided they are not placed closer than five feet from any lot line. Two abutting property owners may erect a common accessory structure across or abutting upon a common lot line in the rear yard setback area, provided that such property owners supply the Zoning Officer with a copy of a written agreement for the erection and use of the structure, which agreement has been approved by the municipal solicitor as to form and content, and which is suitable to be recorded in the Office of the Recorder of Deeds.
