Oakley limits front yard fences to 3.5 feet in height and rear/side yard fences to 6 feet, with corner lot sight-triangle restrictions near intersections. Fences over 6 feet require a building permit, and agricultural-zoned parcels may allow taller fences for livestock.
Oakley Municipal Code Title 9 (Zoning) establishes fence height limits that vary by yard location. In residential zones, front yard fences are limited to 3.5 feet (42 inches) in height to preserve visibility and neighborhood character β a limit applied from the front property line back to the front building line. Rear and side yard fences may be up to 6 feet tall without a building permit. Fences exceeding 6 feet require a building permit from Oakley Community Development, and typically require evidence of structural engineering for wind and seismic loads given Oakley's Delta breezes. Corner lot "sight triangle" restrictions apply at the intersection of two streets or at driveways β within the triangle (typically 25 feet along each property line from the corner), fences cannot exceed 2.5β3 feet to preserve traffic visibility. Agricultural and agricultural-residential zones may allow taller perimeter fencing (up to 8 feet) for livestock containment. Pool enclosures have specific rules under California Health & Safety Code 115920β115929 requiring a minimum 60-inch barrier. HOAs in newer Oakley subdivisions frequently impose additional fence material and color restrictions, and often prohibit chain-link in front yards.
