In unincorporated Stanislaus County, fences in required side and rear yards may reach eight feet, but fences in a required front yard (or the street-side yard of a corner lot) are limited to three feet so visibility is preserved. Fences over seven feet need a building permit.
Stanislaus County does not require a building permit for ordinary residential fences up to seven feet. The Planning FAQ states fences over seven feet require a building permit plus engineering, and the fence must still meet the Title 21 yard height limits regardless of whether a permit is needed.
Stanislaus County's Title 21 governs fence height and placement, but cost-sharing for a boundary fence between neighbors is set by California's statewide Good Neighbor Fence Act (Civil Code §841), which presumes adjoining owners share equally in reasonable construction and maintenance costs after 30 days' written notice.
Stanislaus County's Title 21 zoning ordinance sets fence heights but contains no separate retaining-wall height section, so retaining walls are governed mainly by the California Building Code. A building permit is generally required once a retaining wall exceeds the state exemption height or supports a surcharge.
Beyond height limits, Stanislaus County's Title 21 requires fences in front and corner-side yards to preserve street visibility. Heights are measured from the ultimate (planned) property line, and corner lots get extra setbacks at vehicle openings. The County also requires screening fences/walls in certain non-residential situations.
Stanislaus County's Title 21 zoning ordinance regulates fences by height and visibility, not by a list of approved or prohibited materials for ordinary residential fences. Masonry and concrete fence walls, and any fence over seven feet, are subject to structural review and building permits.
Stanislaus County allows broad choice of fence materials for residential properties. Title 21 controls fence height and visibility rather than material type, so wood, vinyl, chain link, and masonry are all generally permitted, with masonry walls and fences over seven feet requiring a building permit and engineering.
