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

Sierra County has no carport-specific ordinance, but carports are addressed within the zoning district regulations. In the RR-1 rural residential district (SCC 15.12.190), permitted uses expressly include a private automobile garage and/or carport and accessory structures customarily appurtenant to residential use. The same section requires each parcel to maintain one garage, carport, or off-street automobile parking space per single-family dwelling unit. A carport, as an accessory structure, must comply with the district's development standards: height may not exceed two stories or 35 feet, the side yard setback is 15 feet, and the rear yard setback is 30 feet (30 feet on all sides for corner lots); the front yard is the greater of 60 feet from the road centerline or 35 feet from the front property line. Setback and height standards differ in other zoning districts (for example RR-1.5, RR-2, OS-20), so owners should confirm their parcel's zone. Whether a carport needs a building permit is governed by the California Building/Residential Code as adopted in SCC Title 12; the county's permit-exemption list (SCC 12.04.030) does not list carports among the exempt structures, so most carports require a building permit and must meet wildfire-exposure construction standards (CBC Chapter 7A). For ADU purposes, a carport that is demolished or converted does not require replacement parking under SCC 15.10.030.
