Which materials are not allowed?
The city lists barbed wire, electrified fences, plain exposed concrete block, plastic, chain link and grape stakes as prohibited. Ask the city how that list applies to your property type before you pick a product.
What about a backyard media or living wall?
In a rear setback it is held to 7 feet as well.
And the HOA?
Your association can be stricter than the city. See HOA approval for fences.
