The lot, setback and height requirements shall comply with Paragraphs 4.3 through 4.8 for the applicable zoning district unless modified by special provision, exceptions and conditions contained elsewhere in this ordinance.

Building height refers to the vertical distance between the base flood elevation and: (1) the average height level between the eaves and ridge line of a gable, hip or gambrel roof; (2) the highest point of a mansard roof; or (3) the highest point of the coping of a flat roof.

1. Fences or Walls: In the case of fences or walls, height shall be measured from ground level on the higher side of the fence or wall.
2. Exceptions to Height Limits: Unless otherwise expressly stated, the height limitations of this Ordinance shall not apply to any of the following:
   1. Farm buildings in any Agricultural zoning (A) district or the RC district;
   2. Electrical power transmission lines;
   3. Belfries, cupolas, spires, domes, monuments, flagpoles, chimneys, radio/television receiving antennas or chimney flues; or
   4. Bulkhead, elevator, water tank, or any other similar structure or necessary mechanical appurtenance extending above the roof of any building, if such structure does not occupy more than 33 1/3 percent of the area of the roof.

In the absence of public water or public sewer, no building permit shall be issued until the lot meets all the requirements of the Subdivision Regulations and the South Carolina Department of Health and Environmental Control.

No lot shall be so reduced in size as to result in the violation of any requirement of this ordinance or of the Subdivision Regulations.

A lot may be subdivided provided that all resulting lots and structures comply with the provisions of this ordinance and the Subdivision Regulations. If a lot is occupied by a nonconforming structure, it may be subdivided provided that subdividing does not create a new nonconformity or increase the degree of nonconformance of the structure.

Open eaves, cornices, window sills and belt courses may project into any required setback a distance not to exceed 36 inches. Open uncovered porches, uncovered steps, or open fire escapes may project into a front or rear setback a distance not to exceed 8 feet. Fences, walls and hedges may be erected in any required setback or along the edge of lot, provided that in the RC, AG, and AR districts, no fence, wall or hedge located in a front setback shall exceed 4 feet in height, and additionally, in the AR district, no fence, wall or hedge shall exceed 7 feet in height, along any other setback.

Building coverage refers to the area of a lot covered by buildings (principal and accessory) or roofed areas, as measured along the outside wall at ground level, and including all projections, other than open porches, fire escapes, canopies and the first two feet of a roof overhang.
