Before You Build in Rohnert Park, CA: Permit & Rule Checklist (2026)

Rohnert Park does not require a building permit for residential fences, but fences must comply with Chapter 17.14 (Fence, Wall, and Landscape Standards) of the Zoning Code. Fences, walls, hedges, and vegetation cannot exceed 3 feet within the clear vision triangle at corners and driveways per § 17.14.040, and standard residential height limits apply outside that triangle. The Planning Department at 130 Avram Avenue handles questions.

Rohnert Park zoning permits standard residential fence materials (wood, vinyl, masonry, ornamental metal, chain link). Barbed wire, razor wire and electric fencing are generally restricted in residential zones.

Shared boundary fences in California are governed by the Good Neighbor Fence Act (CA Civil Code §841), presuming adjoining owners share the cost of a boundary fence equally after 30 days' notice. Spite fences over 10 feet are a private nuisance (§841.4).

Rohnert Park zoning typically allows fences up to 6 feet in side and rear yards and 3–4 feet in front yards, with corner-lot sight-visibility limits. Taller fences require a permit or variance.
