Oro Valley FAQ
Can I put barbed wire on my fence in Oro Valley?
No. Barbed wire, razor wire, and concertina wire are prohibited in residential zoning districts. These materials are restricted to agricultural, rural-density, and approved commercial or industrial zones.
Does my fence need to allow drainage to pass through?
Yes. Fences may not obstruct drainage paths, floodways, or recorded drainage easements. This is especially important in the Catalina foothills where monsoon runoff follows natural desert washes.
Tucson FAQ
How deep do fence posts need to be in Tucson?
At least 24 inches set in concrete for wood fences up to 6 feet. Taller or more exposed fences need deeper and wider footings to handle monsoon wind gusts up to 115 mph.
Can my fence sit on the property line?
Yes in most Tucson residential zones, though prudent practice is to build a few inches inside your surveyed line. Corner visibility triangles still apply and may force a shorter fence near intersections.
