(A)   The R-2 Residential District is established as a district in which the principal use of land is for multi-family dwellings.
      (1)   A dwelling is a residence where people live for domestic purposes. Domestic use is defined as devoted to home duties and activities, nothing in this section shall preclude one-, two- and multi-family homes from being used as a vacation rental home consisting of a minimum of two overnight stays.
      (2)   Transient occupancy not consisting of at least two overnight stays shall be considered to be inconsistent with domestic residential usage and is not allowed. This would include persistent usage for group gatherings for the purpose of short-term social or recreational activities. This would include use as a clubhouse, lodge, public or private clubs, cabana clubs and property owner association facilities except when contiguous, owned by and within the borders of an on-island residential subdivision.
   (B)   Permitted uses are set forth in the Table of Permitted Uses, § 157.054.
   (C)    The following uses are special uses and may be permitted subject to a finding by the Board of Adjustment that the additional conditions listed herein and any conditions that are set out in § 157.055(B)(2)(b) are met. Home professional office and home occupations, provided the use is conducted entirely within a dwelling and carried on by the occupants, the use is clearly incidental and secondary to the use of the dwelling for living purposes and the use does not change the character thereof. Furthermore, there is no display, no stock-in-trade nor commodity sold upon the premises and employment is in connection with the home occupation. Such occupation shall be carried on solely within the main dwelling and shall not occupy more than 25% of the floor area of the dwelling. Beauty parlors and barber shops shall not be construed as home occupations and are excluded from the definition of HOME OCCUPATION.
   (D)   Dimensional requirements for R-2.
      (1)   Lot area. Minimum required:
         (a)   For a one-family dwelling, 5,000 square feet.

All impervious structures outside of main structure shall not exceed 30% of buildable land less area of the main structure. All Health Department and CAMA requirements must also be met. Open decks are not considered in the 30% lot coverage of the main structure, but they must meet all setback requirements. Gravel, sand and grassed areas are considered pervious. An approved pervious product shall be allowed to cover 30% of the platted lot in addition to the allowable impervious area. (See definition of APPROVED PERVIOUS PRODUCT.)

      (7)   Off-street parking. Off-street parking shall be provided as required in §§ 157.075 through 157.077 of this chapter.
      (8)   Corner visibility. On a corner lot, nothing shall be erected, platted, or allowed to grow in such a manner as to impede vision over a height of three feet above the centerline grades of the intersecting streets within the triangular area bounded on two sides by the two street centerlines and on the third side by a straight line connecting points on the street centerlines located one-half the street right-of-way width plus 40 feet measured from the intersection of the centerlines.

   (E)   Erosion threatened ocean front lots.
      (1)   In the event that it becomes necessary to relocate a structure that has become threatened by erosion, per below, a Special Use Permit may be authorized to establish the front yard building setback at a distance no less than ten feet from the property line. However if the structure to be relocated can meet CAMA ocean side setback rules (per CAMA guidelines for new construction) and remain within the 25 foot street side setback then no further relief can be given. Each case will be reviewed on its own merits. The conditions specified by the Town Planning and Zoning Board in the granting of this Special Use Permit shall be recorded at the County Register of Deeds Office prior to the execution of this permit.

         (i)   This section shall not limit nor repeal any and all applicable local, state and federal statutes.
