How to apply in Pima County
In Pima County, most residential fences fall under the model code's 7-foot building-permit exemption, so the real approval step is a lightweight zoning or land-use permit built around a simple site plan showing the fence's location, height, and material, checked against setbacks and any corner-lot sight-triangle rule. A fence that will serve as a required swimming-pool barrier is the exception, since barrier fences carry life-safety requirements of their own.
What most fence permit applications include:
- For Pima County, a fence 7 feet or under is exempt from the model code's building permit, the same threshold the IRC uses for other small projects (IRC 2021 R105.2).
- That exemption only removes the building-code permit. It does not authorize skipping a jurisdiction's own zoning approval, which is why an exempt fence can still need its own land-use or zoning permit rather than a building permit (IRC 2021 R105.2).
- Whatever your jurisdiction calls that approval, the application centers on a basic site plan: a drawing of the property showing the fence's location, height, and material, and how it relates to the property lines (common local zoning practice).
- For Pima County, the same plan is checked against required setbacks and, on corner lots or near intersections, a sight-triangle rule that caps fence height so it does not block sightlines for drivers (common local zoning practice).
- For Pima County, a fence that will serve as a required swimming-pool barrier is handled as life-safety work rather than the light zoning process, and at least one state's adopted residential code requires a building permit for barrier fences regardless of the general fence exemption (Oregon Residential Specialty Code 2021, R101.2.2).

Inspections and closing out your permit
In Pima County, inspection follows the permit: a fence that never needed one gets no inspection at all under the model code, and a permitted fence typically gets a single final check rather than the staged inspections used for a house. The exception is a fence serving as a swimming-pool barrier, which gets its own dedicated barrier inspection covering height, gaps, and gate hardware.
- In Pima County: inspection duty attaches only to work for which a permit is required, so a fence that qualified for the permit exemption carries no inspection obligation under the model code (IRC 2021 R109.1).
- In Pima County: where a fence permit was issued, the process skips the staged foundation, frame, and rough-in inspections used for buildings and goes straight to one final inspection once the fence is finished (IRC 2021 R109.1.6).
- In Pima County: that single check is typically a zoning compliance inspection rather than a structural review, confirming the fence matches the approved height and site plan (common local practice).
- A fence built as a swimming-pool barrier breaks that light-touch pattern in Pima County: it is separately inspected for barrier compliance, commonly required before the pool itself can be signed off (ISPSC 305; local pool-barrier inspection programs).
- In Pima County: that barrier inspection checks dimensional rules from the swimming pool and spa code rather than ordinary fence rules, including the minimum 48 inch barrier height and limits on openings and gaps a young child could pass through (ISPSC 305).
- Gate hardware is inspected too in Pima County: a self-closing, self-latching gate is part of the barrier requirement, since an unlatched gate defeats the fence's purpose as a barrier (ISPSC 305).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Pima County permit portal or by phone at 520-724-9000.

- You can apply through the Pima County permit portal or contact the Pima County Development Services Department directly. The links are listed on this page.
- Can a homeowner pull a fence permit themselves in Pima County?
- Under Arizona law (A.R.S. 32-1121(A)(5), (A)(9), (A)(14)(a); 32-1164(A)(2), (B)): Arizona addresses owner-builders through its contractor licensing law rather than through the building code itself. A.R.S. 32-1121(A)(5) exempts property owners who build or improve structures on their own land and do the work themselves, with their own employees, or with duly licensed contractors, as long as the finished structure is for the owner's own occupancy and is not intended for sale or rent. Selling or renting within one year of completion or of the certificate of occupancy is prima facie evidence the project was really undertaken for sale or rent, which defeats the exemption, a rule that functions much like Florida's one-year restriction. The exemption does not waive the underlying permit requirement: several of the chapter's small-job licensing exemptions, including the $1,000 casual-work exemption in A.R.S. 32-1121(A)(14), expressly do not apply whenever the work requires a local building permit, so once a job needs a permit, anyone doing that work for someone else generally must hold an Arizona contractor's license regardless of dollar amount. Acting as a contractor without a license, on permit-required work or otherwise, is a class 1 misdemeanor under A.R.S. 32-1164, carrying a mandatory minimum fine of $1,000 for a first offense and $2,000 for a repeat offense.
