Berkeley FAQ
Can I regrade my backyard without a permit?
Only if under 50 cubic yards, cuts less than 3 feet, and not in hillside or fault zone; otherwise permit required.
Can drainage go onto my neighbor property?
No, runoff must be directed to approved disposal; state Civil Code prohibits altering natural drainage to harm neighbors.
Oakland FAQ
