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

3(A) of the Land Development Ordinance governs where residential accessory structures, including fences, may sit on a lot. The default rule ties every accessory use, building, structure, and fence to the same lot as the home it serves and requires a minimum five-foot separation from any other structure, or whatever greater distance the building or fire code demands. The subsection then creates a narrow, opt-in exception for boundary fencing: fencing used to separate properties in a subdivision may straddle the common property line. Table 106-10b, the accessory-structure dimensional table attached to the same section, repeats the same allowance in note 5, confirming it applies specifically to fences dividing adjoining subdivision lots rather than to fences on a single owner's property.

The straddle exception does not excuse the fence from Surprise's separate screening and fence standards; a fence still needs a wall plan or building permit under Chapter 105 before it goes up, and the community development department reviews fence materials, colors and height as part of that process. Nothing in Sec. 3 assigns cost-sharing or maintenance duties between the two property owners: the section addresses only where the structure may physically sit, not who pays for it or keeps it in repair. Homeowners who want a jointly built fence still need to agree on that arrangement between themselves, because the ordinance's role stops at authorizing the fence's location.

Outside of subdivisions, or for any accessory structure other than a dividing fence, the standard five-foot setback continues to apply, and a fence placed on the line without qualifying for the subdivision exception can be cited as a setback violation.
