Costa Mesa Driveway Rules Rules (2026): What You Need to Know

The Costa Mesa Municipal Code (CMMC) Title 13 (Planning and Zoning) and the city's property maintenance code establish the framework for vehicle parking on private residential property. The fundamental requirement is that all vehicles parked on residential lots must be on an approved hard surface — concrete, asphalt, brick pavers, or permeable pavers that meet city engineering standards. Parking on front lawns, bare dirt, gravel, or landscaped areas is a code violation and subject to enforcement. This requirement applies citywide to all residential zones, from the older single-family neighborhoods on the Westside and Eastside to newer planned communities in South Coast Metro area.

Vehicles parked in driveways may not overhang or encroach upon the public sidewalk. In Costa Mesa's older neighborhoods, many homes from the 1950s and 1960s have relatively short driveways, which can make it difficult to park larger vehicles without overhanging the sidewalk. Sidewalk obstruction is both a CMMC violation and a potential ADA accessibility issue, and Costa Mesa Code Enforcement actively responds to complaints. The driveway apron — the paved transition between the private driveway and the public street — must remain clear and unobstructed for traffic flow and emergency access. Expanding an existing driveway or creating additional paved parking areas requires a building permit and must comply with lot coverage limits, setback requirements, and the city's stormwater management regulations.

Inoperable, dismantled, or unregistered vehicles may not be stored in open view on residential property. Such vehicles must be kept inside an enclosed garage or behind a solid fence or wall that completely screens them from public view from any adjacent street or neighboring property. Covering an inoperable vehicle with a tarp in an open driveway does not satisfy the screening requirement. Garage spaces that were designated as required parking in the original building permit or zoning approval must continue to function as vehicle parking; converting a garage to a bedroom, recreation room, workshop, or storage space without proper permits and provision of replacement parking spaces is a zoning violation. Costa Mesa Code Enforcement handles complaints about driveway and on-property vehicle storage violations, reachable at (714) 754-5623.
