Newport Beach, CA Accessory Structures: Carport Rules (2026)

Carports in Newport Beach are classified as accessory structures under NBMC Title 20 and require a building permit. Carports must meet the setback requirements for the applicable zoning district, typically 5 feet from side property lines and 5 feet from the rear property line in single-family zones. Carport height is limited to one story and must not exceed the maximum accessory structure height for the zone, generally 14 feet. Carport square footage counts toward the lot's maximum floor area ratio and lot coverage limits. Open carports with at least two open sides may receive favorable treatment under coverage calculations compared to enclosed garages. Materials and design must be compatible with the primary dwelling and neighborhood character per NBMC design standards. Carports in the Coastal Zone require additional review and may need a Coastal Development Permit if they increase the building footprint. Properties with existing non-conforming conditions should consult with the Planning Division before adding carports. The Community Development Department reviews all carport applications at (949) 644-3200.
