Mohave County zones its vast unincorporated desert, so the county zoning ordinance—not a blank slate—sets fence heights. Arizona caps nothing statewide; block and masonry walls dominate here for wind, dust, and privacy.
Mohave County requires building permits for masonry and block walls, which carry structural and wind loads. Short wood or wire fences are often exempt. Call Arizona 811 before digging; cities permit separately.
Arizona has no shared boundary-fence statute like California's. Each owner is responsible for the fence on their own land. A wall straddling the property line is settled by agreement or the courts.
Mohave County enforces adopted building codes on unincorporated land, so a retaining wall above the code threshold—generally four feet—needs a permit and engineering. Desert flash-flood drainage must be handled or you face civil liability.

A.R.S. §36-1681(B)
Be entirely enclosed by at least a five foot wall, fence or other barrier as measured on the exterior side of the wall, fence or barrier.
