3 rules for unincorporated Greenville County, South Carolina.
Verified from official government sources
In single-family districts (e.g. R-6), Greenville County requires front setbacks of 20 ft on residential streets, 30 ft on collectors, and 50 ft on arterials, with a 5 ft side and 25 ft rear setback. Corner-lot side yards along a street match front setbacks.
Greenville County Zoning Ordinance Sec. 7:3.3
The minimum depth of the front yard measured from the street right-of-way line shall be 20 feet on a residential service street, 30 feet on a collector street, and 50 feet on an arterial street.
Table 7.3 of the Greenville County Zoning Ordinance sets a 45-foot maximum height in residential districts. Buildings may exceed the limit only if side and rear yards are widened 1 foot for each 3 feet of extra height.
Greenville County Zoning Ordinance Sec. 7:3.7
All buildings may exceed the height limitations of the district if the minimum depth of rear yards and the minimum width of side yards required in the district regulations are increased 1 foot for each 3 feet by which the height of such building exceeds the prescribed height limit.
Greenville County's residential Table 7.3 controls development through lot width, setbacks, and height rather than a single-family lot-coverage percentage. Some special districts do cap coverage (e.g. 50% building coverage in manufactured-home parks); accessory buildings may not occupy over 20% of the rear yard.
Greenville County Zoning Ordinance Sec. 7:3.4
Accessory buildings may be located in the rear yard or side yard provided that they are set back not less than five feet from any lot line and occupy not more than 20 percent of the rear yard.
