Brentwood permits a wide range of fence materials including wood, vinyl, wrought iron, masonry, and chain link, subject to zoning and HOA restrictions. Barbed wire, razor wire, and electrified fencing are prohibited in residential zones. Many HOAs in master-planned communities like Brentwood Hills and Trilogy impose material-specific requirements.
Brentwood's fence material regulations under BMC Title 17 are generally permissive. Wood (including redwood, cedar, and pressure-treated), vinyl, composite, wrought iron, ornamental metal, masonry (brick, block, stucco), and standard chain link are all permitted in residential zones. Barbed wire, razor wire, concertina wire, and electrified fencing are prohibited in residential and most commercial zones; they are allowed only on parcels zoned A (Agricultural) or I (Industrial) for legitimate security or livestock-containment purposes. Fences must be maintained in good repair; leaning, broken, or deteriorated fences can be cited as a nuisance. Many Brentwood master-planned communities (Brentwood Hills, Trilogy, Shadow Lakes, Deer Ridge) have HOA CC&Rs requiring specific materials, colors, and styles—HOA standards may be stricter than city code, and both apply. Corner lots and fences visible from arterials may have additional aesthetic standards under design guidelines.
