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.
Oakley FAQ
Can I install a chain-link fence in my backyard?
Yes, in rear and side yards not visible from a public street. HOA rules may be stricter, so check your CC&Rs.
Is an electric fence legal for my dog?
Buried invisible-fence systems are allowed, but above-ground electrified fences are limited to agricultural zones. A physical fence is still required for most containment.
Can I use barbed wire if I keep horses?
Only if your parcel is zoned agricultural or agricultural-residential. Standard residential zones prohibit barbed wire regardless of animals kept.
