Under the California Building Code as adopted by Oakley, fences up to 6 feet (7 feet in some configurations) in height do not require a building permit, though they must still comply with Oakley zoning standards for height, setbacks, sight triangles, and materials. Fences over 6 feet in height β whether freestanding or on top of a retaining wall β require a building permit from Oakley Community Development, typically costing $100β$300 plus plan check fees. Retaining walls over 4 feet in height (measured from bottom of footing to top of wall) require permits regardless of fence placement, and structural engineering is typically required for retaining walls supporting slopes or structures. Swimming pool enclosure fences are separately regulated under California Health & Safety Code 115920β115929 and require proof of compliance at building permit final. Permit applications typically require a site plan showing property lines, proposed fence location, setbacks, and adjacent structures. Homeowner-built fences are allowed for owner-occupied residences; contractor-built fences require a licensed California contractor (C-13 Fencing license typical). Inspections verify setback, height, structural adequacy, and β for pool fences β self-closing/self-latching gates and no-climb design.
