Fence Permit Requirements
In the City of Flagstaff, installing any fence or wall requires a minor improvement permit from Community Development before construction begins. The Flagstaff Zoning Code's fencing division makes the permit mandatory for every wall and fence it regulates, tying approval to the same minor improvement permit process used for sheds, decks and garden walls, so a homeowner cannot legally build a new fence, or replace an existing one, without first filing for and receiving that permit.
