Boise's Swimming Pools & Spas: The Rules That Matter
Every city handles swimming pools & spas a little differently. In Boise, Idaho, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.
Fencing Requirements
Boise pools require a barrier at least 48 inches tall completely surrounding the pool, with self-closing and self-latching gates. The standard applies to any pool or spa deeper than 24 inches per the Idaho Building Code.
Key details: Minimum Height: 48 inches. Gates: Self-closing and self-latching. Latch Height: 54 inches minimum. Applies To: Pools over 24 inches deep. Code: Idaho IRC Appendix G.
Non-compliant barrier: stop-use notice and correction required. Continued violation: civil penalty and potential drainage order.
This is not one of those rules that cities tend to ignore. Boise actively enforces its fencing requirements requirements.
Above-Ground Pools
Above-ground pools in Boise deeper than 24 inches require a building permit and must meet the 48-inch barrier rule. The pool wall itself can serve as the barrier if the ladder is removable, lockable, or enclosed.
Key details: Permit Threshold: Over 24 inches deep. Setback: Typically 5 ft from property line. Ladder: Removable or lockable. Deck Barrier: 48-inch with gate. Exemption: Under 24 inches and 5,000 gal.
Contact your local code enforcement office for specific penalty information.
Safety Rules
Boise pools must have anti-entrapment drain covers meeting VGB standards, GFCI-protected electrical circuits, and audible door alarms on any house door opening directly to the pool area unless a compliant power safety cover is installed.
Key details: Drain Covers: VGB-compliant required. Electrical: GFCI on all pool circuits. Door Alarms: Required on pool-facing doors. Power Cover: ASTM F1346 alternative. Public Pools: IDAPA 24.39.70.
Contact your local code enforcement office for specific penalty information.
Compared to other cities, Boise takes a harder line on safety rules. The enforcement and penalty structure reflects that.
Pool Permits
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.
Key details: Permit Application: 426 Residential Swimming Pool. Code Basis: IRC + ISPSC. Disturbance Trigger: >500 sq ft or >10 cu yd. Barrier Height: 48 in minimum. Gate Standard: Self-close, self-latch.
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.
The Bottom Line
Boise is tougher than many cities when it comes to swimming pools & spas. Out of the 4 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Boise, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
