Brentwood FAQ
Can I have a chain-link fence in front?
Chain link is legal citywide, but many Brentwood HOAs (Brentwood Hills, Trilogy, Shadow Lakes) prohibit chain link in front or side yards visible from the street. Check your CC&Rs before installing.
Is electric fencing allowed for dogs?
Underground "invisible" pet-containment systems are allowed as they are not structural fences. Above-ground electrified fencing is prohibited in residential zones.
El Cerrito FAQ
Can I install a chain-link front-yard fence in Alamo?
Technically permitted by county code, but Alamo's Municipal Advisory Council design expectations often discourage front-yard chain-link in favor of wood or open-rail. Neighbors can object during any design-review process.
Is electric fencing allowed for my horses in Byron?
Yes in agricultural zones for livestock containment, with proper warning signs and current limits per state livestock-fencing standards.
