Gilbert, AZ Fence Regulations: Neighbor Fence Rules (2026)

9(A)(3), an existing substandard opaque wall or fence on a property line that no longer meets current height requirements for new development may simply be left in its existing condition as long as it is well maintained. It only has to be brought up to current standards if all of the abutting parties agree, in writing, that it should be extended or rebuilt to current standards. 9(C). 9(C)(3)(a) requires the applicant to obtain a notarized owner's signature from a majority of the property owners of all real, contiguous/abutting property affected by the change, submitted with a site plan and detail of the proposed wall or fence.

9(C)(3)(b) allows a request to relocate the wall internal to the site or waive the requirement, but two walls or fences moved this way can never sit closer than 10 feet apart, and two solid walls cannot be arranged to create a corridor that isn't clearly visible from a public or private street. No notarized signature is needed if the modification isn't to a perimeter/separation wall and sits more than 10 feet from the property line, or if it abuts a public right-of-way. The Planning Commission decides modification requests and can later revoke one after a public hearing if the approved conditions aren't met.
