El Cerrito FAQ
Can I grow a 15-foot hedge along my property line?
In principle yes — hedges are not capped at fence heights — but a tall hedge built maliciously to block a neighbor could be challenged as a spite fence under Civil Code §841.4.
Can I trim my neighbor's hedge overhanging my yard?
You can trim back to the property line at your own expense without damaging the plant's health. You cannot enter their property without permission.
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.
