Antioch FAQ
Do I need a permit for a 6-foot backyard fence?
Generally no. Fences 6 feet or under in rear or interior side yards typically do not require a building permit in Antioch, but must still comply with setback and property line requirements.
Why is my front yard fence limited to 4 feet?
Lower front yard fence heights maintain neighborhood sight lines, pedestrian safety, and open character. Antioch's zoning code limits front fences to 3.5–4 feet unless a special exception is granted.

Not for most 6-foot fences in Richmond side/rear yards. Permits are required for fences over 6 feet and for any fence in the front yard exceeding 4 feet.
