Summary
Carports are treated as accessory structures in unincorporated Charleston County, but unlike sheds they are exempt from the rule requiring accessory structures to sit wholly behind the house. They still must meet interior-lot-line and district setbacks.
A detached Accessory Structure shall be located: 1. Wholly to the rear of the Principal Structure, provided that this limitation shall not apply to carports or Garages; 2. At least six feet from any other Dwelling, including those under construction; 3. At least three feet from any interior Lot line in a Residential Zoning District.
Full Breakdown
Under ZLDR Sec. 6.5.8.B.1 a detached accessory structure must be located wholly to the rear of the principal structure, but this limitation does not apply to carports or garages, so a carport may be placed beside or in front of the main house within the district's setbacks. A detached carport must still keep at least six feet from any other dwelling and at least three feet from any interior lot line in a residential district, and meet the district's front-setback requirement. On corner lots it cannot project in front of the adjacent lot's building line. Non-agricultural accessory structures must stay subordinate to the principal structure in height and floor area. Cities within the county set their own carport standards.
Violations & Fines
Carports built over setback lines or without required permits are zoning violations subject to correction and penalties under ZLDR Chapter 11.
