In unincorporated Solano County, fences not over 6 feet in height do not require a building permit. Fences over 6 feet must be permitted through Solano County Building & Safety Services. Zoning standards in Chapter 28 of the County Code may impose additional setback, sight-distance, and screening requirements. California Civil Code Section 841 (Good Neighbor Fence Act) governs cost-sharing between adjoining residential owners.
Solano County Building & Safety Services confirms that fences not over 6 feet high do not require a building permit; fences taller than 6 feet require a building permit, consistent with the California Building Code. Chapter 28 of the Solano County Code (Zoning Regulations) sets the underlying yard, setback, and screening standards that apply to fences in residential, agricultural, and commercial zones. Specific provisions in Chapter 28 require solid fences or masonry walls (commonly 6 feet) where commercial or non-residential uses abut residential properties. Sight-distance rules at intersections and driveways limit obstructions in the visibility triangle. California Civil Code Section 841 (Good Neighbor Fence Act) governs cost allocation between adjoining residential owners; Civil Code Section 841.4 addresses spite fences. Cities (Vallejo, Fairfield, Vacaville, Benicia, Dixon, Rio Vista, Suisun City) enforce their own fence height rules within incorporated limits.
Building or maintaining a fence over 6 feet without a building permit can result in a stop-work order and citation by Solano County Building & Safety Services. Fences placed within required setbacks, sight-distance triangles, or in violation of Chapter 28 zoning standards can be cited by Resource Management Code Compliance. Civil disputes between neighbors over a shared fence are handled in civil court under California Civil Code Section 841.
