Corona, CA Accessory Structures: Carport Rules (2026)

A carport is a roofed open structure used to shelter vehicles and is regulated by Corona under CMC Title 17 (Zoning) and Title 15 (Building). A building permit is required for any carport regardless of size because of the roof structural system; the only exception is a true 'shade structure' under 120 sq ft with no fixed roof. Detached carports must meet accessory structure standards: 5 ft side and rear setbacks, located behind the front building line, and limited to 12 feet in height. Attached carports (extending from the dwelling) follow the main building setbacks for the underlying zone, typically 5 ft side and 20 ft front. Carports cannot be used as enclosed storage; that converts them to a garage requiring full enclosure walls and a different permit class. Front-yard carports (between the front of the dwelling and the street) are prohibited in most R-1 zones to preserve neighborhood character, though some older neighborhoods grandfathered front-yard carports. Carports may count as required covered parking if they are permanent, structurally sound, and at least 10 ft x 20 ft (single) or 20 ft x 20 ft (double). Materials must complement the main dwelling. HOAs may impose stricter color/material rules.
