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.
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.
