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.
Walnut Creek FAQ
Can I build a chain-link fence in my front yard?
Chain link is discouraged in front yards and often requires woven slats or landscape screening to improve appearance. Confirm with Planning whether your specific zone or neighborhood allows it before installing.
Is a stucco wall allowed as a side fence?
Yes, stucco-over-frame walls are allowed up to the standard six-foot side/rear yard height limit. Anything taller requires a building permit and possibly a variance.
