Martinez allows fences up to 6 feet high in side and rear yards and up to 3.5 feet in front yards or within street-facing setback areas. Corner lot visibility triangles have additional height restrictions to preserve traffic sight lines. Fences over 6 feet or in historic downtown areas require a building permit and Design Review Committee approval.
Martinez Municipal Code Title 22 (Zoning) regulates residential fence heights based on yard location. In side and rear yards on single-family residential lots, fences may be up to 6 feet in height without a permit. In front yards and within the front setback area (typically 20 feet from the front property line), fences are limited to 3.5 feet in height to preserve streetscape visibility and neighborhood character. On corner lots, a visibility triangle at the intersection limits fence height to 3 feet within 25 feet of the corner to ensure traffic sight lines. Fences over 6 feet in height (including combined fence-plus-retaining-wall configurations) require a building permit from the Community Development Department. In the downtown historic district and near the John Muir National Historic Site, fence design is subject to additional Design Review Committee or Historic Preservation Commission review to ensure compatibility with the historic character. Materials are generally not prescribed, but barbed wire and electric fences are prohibited in residential zones. Pool fences must comply with California Health & Safety Code Β§115920 (minimum 60 inches / 5 feet). Hillside parcels may have additional fence restrictions to preserve views. Permits for fences over 6 feet typically cost $150-$300 with structural review required.
