Oakley FAQ
Does my neighbor have to pay half of a new fence?
Under CA Civil Code 841, yes — but only if you provide the required 30-day written notice and the project is reasonable. They can rebut the presumption.
How do I find my actual property line?
Hire a licensed land surveyor. City records, title documents, and subdivision maps provide starting points but a survey produces defensible line markers.
What is a spite fence?
A fence over 10 feet tall built primarily to annoy a neighbor, prohibited by CA Civil Code 841.4. Affected neighbors can sue for abatement and damages.
Walnut Creek FAQ
How tall can I let my hedge grow between me and my neighbor?
Up to six feet in side or rear yards. In a front-yard setback the hedge is limited to about 3.5 feet, and within a corner sight triangle no more than 30 inches. Enforcement is complaint-based.
My neighbor's bamboo is invading my yard — what are my rights?
Under California law, bamboo is the responsibility of the property where it is rooted. You can trim any portion that crosses the property line at the line itself, and you can require the neighbor to install a root barrier or remove spreading plants as a nuisance.
