Walnut Creek's Fence Regulations: The Rules That Matter
Every city handles fence regulations a little differently. In Walnut Creek, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

If you are coming from a city with tighter rules, you will find Walnut Creek gives residents more flexibility on material restrictions.

Key details: Permit-exempt max: 4 feet (no surcharge). Permit trigger: Over 4 ft or any surcharge. Engineer stamp: Required for permitted walls. Fence on top: Measured from high-side grade. Drainage: Must not runoff to neighbor.
