Placer County, CA Accessory Structures: Carport Rules (2026)

In unincorporated Placer County, a carport is a roofed structure used to shelter vehicles and is regulated as a detached accessory structure under the Placer County Zoning Ordinance (Chapter 17). Unlike a small tool or storage shed - which is permit-exempt up to 120 square feet - a carport is a roofed structure that typically requires a building permit from Placer County Building Services because of its structural and roof loads. The carport must comply with the setback and height standards for accessory structures established by the Zoning Ordinance for the parcel's specific zone district; the Planning Division determines allowable setbacks from property lines. Carports attached to a dwelling are reviewed as part of the dwelling's footprint and must meet the dwelling's setbacks. Because a carport is open on one or more sides, design and fire-rating requirements differ from an enclosed garage, but it still must satisfy building code and, where applicable, defensible-space and fire-resistive requirements in State Responsibility Area and high-fire-severity zones. In the Tahoe Basin, the Tahoe Regional Planning Agency (TRPA) reviews land coverage, so a carport may count toward coverage limits and requires a second permit. Placer County advises owners to confirm setbacks, height and permit requirements with CDRA Planning and Building Services (Auburn 530-745-3000; Tahoe 530-581-6200) before construction.
