Article 4.2 Measurements, Computations, and Exceptions


 

§4.2.1 DENSITY

Density refers to the number of dwelling units per unit of land area. Density is calculated by dividing the number of dwelling units on a site by the gross area (in acres) of highland (including freshwater wetlands) of the site on which the dwelling units are located. The number of dwelling units allowed on a site is based on the presumption that all other applicable standards of this Ordinance shall be met. The maximum density established for a district is not a guarantee that such densities may be obtained, nor shall the inability of a development to achieve the stated maximum density be considered sufficient justification for varying or otherwise adjusting other density, intensity or dimensional standards of this Ordinance.

§4.2.2 LOTAREA

A. MEASUREMENT

Lot area refers to the horizontal land area within lot lines, including freshwater wetlands.

B. EXCEPTIONS

No zoning permit, building permit or development approval may be issued for a lot that does not meet the minimum lot area requirements of this Ordinance except in the following cases:

  1. Nonconforming lots may be used in accordance with the provisions contained in Chapter 10 of this Ordinance.
  2. Utilities using land or an unoccupied building covering less than 1,000 square feet of site area shall be exempt from minimum lot area standards.

C. ABSENCE OF SEWER OR WATER

In the absence of public water or public sewer, no zoning permit or building permit shall be issued until the lot meets all applicable requirements of this Ordinance and the South Carolina Department of Health and Environmental Control (DHEC).

§4.2.3 SETBACKS

Setbacks refer to the unobstructed, unoccupied open area between the furthermost projection of a structure and the property line of the lot on which the structure is located, except as modified by the standards of this section.

A. EXCEPTIONS TO SETBACKS

Every part of a required setback must be open and unobstructed from the ground to the sky except as set out in this subsection.

  1. Trees, shrubbery or other landscape features may be located within any required setback.
  2. Fences and walls may be located within any required setback, provided that in residential, office and commercial districts no fence, wall or hedge shall exceed:

a.

4 feet in height when located within any front or street side setback;

b.

8 feet in height when located in an interior side or rear setback.

  1. Driveways may be located in front and street side setbacks.
  2. Sidewalks may be located within any required setback.
  3. Utility lines, wires and associated structures, such as power poles, may be located within any required setback.
  4. Uncovered porches, uncovered steps to building entrances, uncovered patio decks and uncovered balconies may extend up to 5 feet into any required front, rear or street side setback.
  5. Openwork fire balconies and fire escapes may extend up to 5 feet into any required side setback.
  6. Sills, belt courses, cornices, buttresses, eaves and other architectural features may extend up to 2 feet into any required setback.
  7. Chimneys and flues may extend up to 2 feet into any required setback.
  8. Satellite dish antennas may be placed in required rear setbacks.
  9. Mechanical equipment, including Heating Ventilation and Air Conditioning (HVAC) equipment, may be extended up to 5 feet into required side or rear setbacks in all zoning districts.

B. CONTEXTUAL SETBACKS

Notwithstanding the front setback requirements of the underlying zoning district, the front building line of any structure or addition to a structure may be as close to the street as the front building line of a structure located on any lot that is immediately adjacent to the subject lot. If the subject lot is located between 2 developed lots, the front building line of the structure that is set back further from the street shall apply to the subject lot.

C. SETBACK REDUCTIONS

Where the front, interior side and rear setbacks of the underlying zoning district reduces the buildable width of a lot to less than 40 feet, the Planning Director shall be authorized to reduce the required setbacks as much as necessary. However, no setback reduction granted by the Planning Department shall be for more than 15 feet.

D. FRONT SETBACKS ON NARROW STREETS

Where a lot abuts a dedicated street (that has been accepted for street maintenance) with a right-of-way width of less than 50 feet, the required front setback shall be measured from a line measured 25 feet from the center of such right-of-way.

E. SETBACKS ON CORNER AND DOUBLE-FRONTAGE LOTS

On corner and double-frontage lots, front setback standards will apply to each lot line that borders a street. The remaining lot lines will be subject to side setback standards. There is no rear lot line.

F. REDUCTION FOR PUBLIC PURPOSE

When an existing setback is reduced because of conveyance to a federal, state or local government for a public purpose and the remaining setback is at least 50 percent of the required minimum setback for the district in which it is located, then that remaining setback will be deemed to satisfy the minimum setback standards of this Ordinance.

§4.2.4BUILDINGHEIGHTBuilding Height

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.

A. 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.

B. EXCEPTIONS TO HEIGHT LIMITS

  1. Farm buildings in any Agricultural zoning (A) 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 33a percent of the area of the roof.

§4.2.5 BUILDING COVERAGE

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 2 feet of a roof overhang.
