Walnut Creek allows 3 feet in the front setback and 7 feet in side and rear setbacks. Under Walnut Creek Municipal Code Section 10-2.3.104, a fence or gate may not exceed 3 feet within the required front setback and may reach 7 feet in interior side and rear setbacks. At those heights no fence permit is required; anything taller needs a Minor Use Permit. The city also regulates materials: fences should be wood, iron, or steel, and chain link is not allowed where it is visible from the street, which makes a fabricated iron or steel gate the code-friendly choice. Corner lots have extra front-height limits.Because an automatic gate adds an operator and wiring, the electrical work typically needs its own permit. Rules change and every lot is different, so we confirm the current requirements with the city and pull the permits the gate and automation need.
