Swimming pool permit rules in Boise, ID — also covering above-ground pools, in-ground pools, and spa installations — set fencing, barrier, alarm, and inspection requirements.
Boise requires a Residential Swimming Pool Permit (Application 426) for any in-ground or above-ground residential pool, plus pool barriers that meet the IRC and International Swimming Pool and Spa Code (ISPSC) adopted by the city. Any residential project disturbing more than 500 square feet or excavating more than 10 cubic yards (which includes pools) triggers a building permit.
Permits are issued by Boise Planning & Development Services (PDS) Building Division through Application 426 - Residential Swimming Pool, available online at permits.cityofboise.org or in person at 150 N Capitol Blvd. Idaho has adopted the International Residential Code (IRC) and International Swimming Pool and Spa Code (ISPSC), and Boise enforces them under Title 4 of the city code. Residential additions or improvements that disturb more than 500 square feet or involve more than 10 cubic yards of excavation, including swimming pools, require a building permit. Pool barriers must comply with IRC Appendix AG (Section AG105) and ISPSC: a minimum 48-inch-tall barrier with no openings that allow a 4-inch sphere to pass through, and self-closing, self-latching gates opening outward from the pool. The Building Division inspects barriers as part of the pool permit. Submit a site plan showing pool location and setbacks, structural details, equipment locations, and the barrier plan. Confirm current fees and required inspections with PDS at (208) 608-7070 before construction.
Constructing or installing a residential swimming pool without Application 426 approval, or filling/operating a pool before barrier inspection passes, violates Boise's adopted building code and can result in stop-work orders, removal, and code-enforcement penalties through Planning & Development Services.
