Union City treats detached carports as accessory structures under UCMC Chapter 18.32. Carports must sit on the rear half of the lot, meet four-foot side and rear setbacks, and stay within the 12-foot height limit, with permits required above small sizes.
Detached carports are regulated as accessory structures under Chapter 18.32 (Residential Districts). They must be on the rear half of the lot and never forward of the main structure, kept at least four feet from side and rear property lines and five feet from other structures. Height is capped at one story and 12 feet, up to 14 feet to match the main roof pitch if the roof midpoint stays at 12 feet. Detached structures under 120 square feet with no utilities need no permit; larger ones require a building permit, and those over 450 square feet require planning approval too. Carports count toward the 30 percent rear-yard coverage cap. Attached carports follow the main building's setbacks.
Erecting a carport in a front yard, within required setbacks, or above height or coverage limits can trigger code-enforcement notices and orders to relocate or remove the structure.
