Why Kennewick Has Some of the Strictest Swimming Pools & Spas in the State

Kennewick maintains 100 local ordinances across all categories, and 3 of those deal specifically with swimming pools & spas. Here is a breakdown of what the city actually requires, what is prohibited, and where Kennewick falls on the strict-to-permissive spectrum compared to other cities.

Fencing Requirements

Residential pool fencing in Kennewick must meet IBC Appendix G and ISPSC Section 305 as adopted into the Washington State Building Code at WAC 51-50, and enforced locally through KMC Chapter 15.44. A 48-inch minimum barrier, self-closing/self-latching gates opening away from the pool, no climbable horizontal members on the outside, and house-wall openings protected by an alarm or self-closing device are all required.

Key details: Barrier Height: 48 inches minimum. Bottom Clearance: 2 inches grade / 4 inches pool side. Sphere Test: No 4-inch sphere through openings. Gate: Self-closing, self-latching, outward swing. House Doors: Alarm (UL 2017) or self-closing latch.

Pool-barrier violations are State Building Code violations under RCW 19.27 enforced by Kennewick Code Enforcement. Penalties include stop-use/drain-down orders, daily Class 1 civil infraction fines under KMC 1.04, denial of the final inspection, and personal civil liability for any drowning under Washington premises-liability law. For public pools, the Benton-Franklin Health District may suspend the permit-to-operate under WAC 246-260.

This is one of the stricter rules in Kennewick's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Pool Permits

All swimming pools in Kennewick - in-ground, above-ground, and storable pools capable of holding water 24 inches or deeper - require a building permit under Kennewick Municipal Code Chapter 15.44 and the Washington State Building Code (WAC 51-50). The permit covers electrical bonding under NEC Article 680, barrier compliance under IBC Appendix G, setbacks under KMC Chapter 18.27, and final inspection.

Key details: Permit Trigger: Any pool 24+ inches deep. Issuer: Kennewick Building Division. Standards: WAC 51-50 + KMC 15.44 + NEC 680. Setbacks: Per KMC 18.27 accessory rules. Public Pools: Add: WAC 246-260 health permit.

Installing or filling a pool without a permit is a State Building Code violation under RCW 19.27 and KMC Chapter 15.44. Penalties include stop-work orders, daily Class 1 civil infraction fines, mandatory drain-down until inspections pass, and refusal of any future Certificate of Occupancy for the property. Operating an unpermitted public pool exposes the owner to Benton-Franklin Health District closure under WAC 246-260.

Compared to other cities, Kennewick takes a harder line on pool permits. The enforcement and penalty structure reflects that.

Safety Rules

Pool safety in Kennewick is governed by a layered set of standards: the federal Virginia Graeme Baker Pool and Spa Safety Act (15 USC 8003) for anti-entrapment drain covers on public pools and spas; Washington's water recreation facility rules at WAC 246-260 under RCW 70.90 for public/semi-public pools; NEC Article 680 and WAC 296-46B-680 for electrical bonding and GFCI; and IBC Appendix G / ISPSC via WAC 51-50 for residential barriers and door alarms.

Key details: Federal Drain Covers: VGB Act 15 USC 8003 (public pools). State Pool Rule: WAC 246-260 + RCW 70.90. Electrical: NEC Art. 680 / WAC 296-46B-680. Residential Barriers: WAC 51-50 / IBC App. G / ISPSC. Public-Pool Permit: Benton-Franklin Health District.

VGB Act violations are subject to CPSC civil penalties (up to over $100,000 per violation under 15 USC 2069 as adjusted for inflation). Washington water recreation facility violations on public pools are enforced by the Benton-Franklin Health District with fines and immediate closure orders under WAC 246-260. Residential State Building Code violations are enforced by Kennewick under RCW 19.27 and KMC Title 15 with daily Class 1 civil infraction fines plus civil liability to any injured party.

Compared to other cities, Kennewick takes a harder line on safety rules. The enforcement and penalty structure reflects that.
