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

A carport in unincorporated Tuolumne County is treated as an accessory structure under the County's Title 17 (Zoning) standards. Like other accessory structures, a carport's height is dictated by Tuolumne County Ordinance Code Chapter 17.22 (with building-height limitations also under Chapter 15.20.010), and it must meet the spacing and setback regulations of the zoning district in which it is located. Because a carport provides covered off-street parking, the County's parking standards in Chapter 17.30 of the Ordinance Code are relevant; that chapter sets out on-site, off-street parking requirements for residential and mixed-use development and gives the Director authority under Chapter 17.30.110 to approve a reduction, modification, or elimination of parking spaces upon a determination that conditions or use justify the change. A permanent, structurally attached or freestanding carport generally requires a building permit so that footings, post connections, and roof loads (including snow loads in higher-elevation parts of the County) are reviewed. Setbacks vary by zoning district, so a carport that encroaches into a required side or rear yard, or that exceeds the district height limit, would not comply. Parcels within combining districts (such as Airport Combining Districts under Chapter 17.20.050) may carry additional siting constraints. Confirm the specific district setbacks and permit requirements with the Community Development Department before building.
