Edmond, OK Accessory Structures: Carport Rules (2026)

Oklahoma County carport regulation stricter than some accessory structures due to wind load concerns. Oklahoma City §155-40 and the Building Code require a permit for all carport construction regardless of square footage, unlike sheds which have a 120-square-foot exemption. Carports classify as accessory structures under the zoning code with specific setback requirements: typically 25 feet from the front property line (matching the primary dwelling front setback), 5 feet from side property lines, and 5 feet from rear property line in R-1 and R-2 zones. Maximum height 15 feet in most residential zones. Attached carports follow the primary dwelling's setbacks and height limits. Lot coverage including the carport cannot exceed zone maximums (typically 30-40% residential). Structural requirements include 90 mph design wind speed (Oklahoma City is in a significant tornado/severe wind zone) with proper anchoring — surface-set prefabricated carports must be bolted to concrete pads or piers. Materials must be non-combustible within 3 feet of property lines (metal roofing preferred). Prefabricated metal carport kits sold at home improvement stores still require full permits — many homeowners mistakenly believe otherwise. HOAs frequently restrict or prohibit carports in favor of garages in newer neighborhoods. Edmond Code §22-73 mirrors OKC. Structures supporting only solar panels may follow different rules.
