Quick answer
Pima County requires a building permit for custom in-ground residential pools, processed through the Development Services Administrative Review submittal process (construction drawings, sealed structural calculations, and possible review by Regional Flood Control District, Regional Wastewater Reclamation, or the Department of Environmental Quality). The county's "Do I Need a Permit?" list separately confirms a permit is required for pre-fabricated above-ground pools once they exceed 18 inches of depth and 5,000 gallons. Any pool, spa, or contained body of water must also have a compliant safety barrier under Pima County's adopted 2018 International Swimming Pool and Spa Code (minimum 48-inch barrier height, self-closing/self-latching gate); Arizona's statewide pool-barrier statute, A.R.S. Section 36-1681, sets an equivalent baseline barrier requirement.
Typical threshold: Pre-fabricated residential pools installed entirely above ground require a building permit once they exceed 18 inches in depth and 5,000 gallons; any in-ground or custom-built residential pool or spa requires a building permit through Administrative Review regardless of size.

What your pool permit must meet in Arizona
Arizona has a statewide law requiring a compliant physical barrier around residential swimming pools and spas, independent of whichever local building code applies to the rest of a project.
- The barrier requirement applies to any pool or contained body of water at least 18 inches deep and wider than 8 feet, under A.R.S. 36-1681.
- The pool must be entirely enclosed by at least a 5 foot wall, fence, or other barrier measured on its exterior side, under A.R.S. 36-1681.
- The barrier cannot have openings large enough for a 4 inch diameter sphere to pass through, under A.R.S. 36-1681.
- Pool gates must be self-closing and self-latching, with the latch mounted at least 54 inches above the ground, under A.R.S. 36-1681.
Based on A.R.S. 36-1681 (Pool enclosures; requirements; exceptions; enforcement). Read the code. Local amendments can be stricter; confirm the current requirement with your office before you build.

How to apply in Pima County
A residential pool permit application covers both construction and safety: a scaled site plan, structural plans for the pool, a barrier plan showing how the pool will be enclosed, and an electrical plan covering bonding and the equipment disconnect.
What most pool permit applications include:
- Pool and spa design and construction fall under the residential code chapter that folds in the swimming pool and spa code, and permit review checks plans against that chapter (IRC R326).
- The site plan must show pool equipment such as pumps, filters, and heaters set back at least 36 inches from the outside of the required barrier (ISPSC 305.2.9).
- For an in-ground pool, engineered structural plans covering the shell and reinforcing steel, with the responsible structural engineer's license information, are a standard part of the submittal (per official pool submittal checklists).
- A barrier plan identifying the fence, pool structure, or dwelling wall that will enclose the pool must be submitted and must comply with the code's barrier chapter (ISPSC 305).
- Electrical plans must show the pool's equipotential bonding design, since the shell, perimeter surfaces, and metal fittings within 5 feet of the water must all tie into a common bonding grid (NEC 680.26).
- The electrical plan must also show a disconnecting means for the pool equipment that is readily accessible and within sight of the equipment (NEC 680.13).

Inspections and closing out your permit
Pool inspections track the concrete pour: the steel and bonding grid are checked before gunite or shotcrete goes in, bonding is checked again before decking is poured, and the permanent barrier and remaining electrical work are checked at final before the pool can be filled and used.
- Before gunite or shotcrete is sprayed, the inspector checks the rebar against the engineered plans and confirms the equipotential bonding wire is stubbed out and tied into the steel, since it will be buried in concrete afterward (NEC 680.26).
- A bonding inspection separately confirms coping, decking, ladders, handrail cups, and any other metal within 5 feet of the water are tied to the bonding grid, and it must pass before coping is installed (NEC 680.26).
- A temporary barrier at least 4 feet high must enclose the site from the moment excavation starts until the permanent barrier is finished, and inspectors check for it throughout construction (ISPSC 305.1.1).
- A pre-plaster inspection confirms the circulation equipment's electrical work is installed and all bonding is complete before the pool's interior finish goes on (NEC 680.26).
- At final inspection the permanent barrier is checked against the code's requirements and the equipment and cover-mechanism bonding must be complete before the pool can be filled and used (ISPSC 305, NEC 680.26).
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.
