Navajo County, AZ Fence Regulations: Height Limits (2026)

5 feet in the front yard and 7 feet along the side and rear yards, for both the larger 43,000-square-foot R1-43 lots and the smaller 10,000-square-foot R1-10 lots. 5-foot front and 7-foot side/rear figures repeat in Section 603 for the R Multi-Family Districts, so the front-yard limit is consistently the tighter number across the county's residential zones. A separate, stricter rule takes over on corner lots. Section 1907 limits the height of fences, walls, gateways, ornamental structures, hedges, shrubbery, and other fixtures at street intersections in every zoning district where a front yard is required: within 25 feet of the intersecting corner along each adjoining lot line, nothing may exceed 2 feet above the elevation of the nearest street, preserving the sight triangle drivers need to see cross traffic.

That 2-foot corner limit controls even where the general Section 503 table would otherwise allow a taller front-yard fence, because Section 1907 is written as an additional limitation layered onto the district standards rather than a replacement for them.
