Phoenix does not require a building permit for a residential fence 3 feet or lower; a fence over 3 feet through 6 feet requires a permit for zoning and site-drainage compliance, and a fence over 6 feet requires full building-code review.
Zoning location, sight triangles, historic properties, retaining walls, drainage, easements, pool barriers, and right-of-way work remain separate.
