Summary
Building a swimming pool, spa, or pool barrier in Phoenix requires a building permit from the Planning & Development Department, with two mandatory inspections (pre-gunite and pre-plaster). Only small above-grade prefabricated pools (≤ 5,000 gallons) are exempt from the structure permit, and even those still require a separate permit for the pool barrier.
10. Prefabricated swimming pools accessory to a Group R-3 Occupancy, in which the pool walls are entirely above adjacent grade and if the capacity does not exceed 5,000 gallons (18 925L). Barriers shall be installed in accordance with Appendix G, Section AG105 of the International Residential Code (IRC).
Commentary: A permit is required for the installation of a pool barrier for a prefabricated swimming pool to assure compliance with Section AG105.
Full Breakdown
Pool construction in Phoenix is governed by the Phoenix Building Construction Code (PBCC) and the 2024 ISPSC as amended by Ordinance G-7397. 2 (Work Exempt from Permit), the only pool exempt from a structure permit is a prefabricated above-grade pool accessory to a Group R-3 (residential) occupancy that holds no more than 5,000 gallons, and the City's published commentary confirms that even for that exempt prefab pool, a permit is still required for the pool barrier. For all other in-ground and on-ground pools, spas, and hot tubs, a building permit is required, and the pool is checked at two inspections: a pre-gunite inspection of the structural shell and a pre-plaster inspection that verifies the life-safety barrier provisions before the pool may be plastered or filled.
A new permit is also required to enlarge, alter, repair, remove, convert, or replace an existing approved pool barrier. Permit applications are handled by the Planning & Development Department (Development Services), reachable at (602) 262-7811. S. Section 36-1681, which sets the minimum enclosure standards a permitted pool must satisfy.
Violations & Fines
Constructing a pool, spa, or barrier without the required permit, or filling/plastering a pool before barrier inspection approval, is a code violation that can trigger stop-work orders and after-the-fact permitting through Planning & Development. Barrier non-compliance can additionally be charged as a petty offense under A.R.S. Section 36-1681.
