Green Valley FAQ
Do I need a permit for a 6-foot block wall?
In most residential zones a 6-foot side or rear wall does not require a permit, but masonry walls over 6 feet need a building permit and possibly engineered plans from Pima County Development Services.
Can I install barbed wire on my property?
Barbed wire is allowed on parcels zoned GR-1 (1 acre minimum) or larger rural parcels for agricultural purposes. It is generally prohibited in standard residential subdivisions.
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.
