Summary
A carport is an accessory structure in Greenville County. It follows the same accessory-building rule: in the rear or side yard it must be set back at least five feet from any lot line, and it may not cover more than 20% of the rear yard.
Accessory Building – An incidental subordinate building customarily incidental to and located on the same lot occupied by the main use or building, such as a detached garage.
Full Breakdown
The Greenville County Zoning Ordinance defines an accessory building as an incidental, subordinate building such as a detached garage, and carports are regulated as accessory structures. Like sheds and detached garages, a carport in the rear or side yard must be set back at least five feet from any lot line and may not occupy more than 20% of the rear yard. Any carport attached to the principal dwelling is treated as part of that structure and must meet the district's principal-building setbacks. In the rural R-R1, R-R3, AG, and (on 1+ acre) R-S districts, detached accessory structures may sit in the front yard only if kept 30 feet from any right-of-way. Cities set their own carport rules.
Violations & Fines
A carport within five feet of a lot line, or covering more than 20% of the rear yard, is a zoning violation subject to correction or removal by Greenville County Code Compliance.
