Swimming Pools & Spas in Kirkland, WA: What Residents Actually Need to Know
If you live in Kirkland or are thinking about moving there, swimming pools & spas are one of those things you probably won't think about until they affect you directly. Kirkland has 2 specific rules on the books covering different aspects of swimming pools & spas, and some of them might surprise you.
Pool Permits
Kirkland requires a building permit under KMC 21.06.205 to construct an in-ground or deep residential pool, and the pool must meet the International Swimming Pool and Spa Code per KMC 21.06.078. Only a prefabricated, above-ground pool less than 24 inches deep is exempt from the permit under KMC 21.06.215(1)(K).
Key details: Permit-exempt pools: Prefab, above-ground, under 24 inches deep. Permit-required pools: In-ground or 24+ inches deep. Applicable code: International Swimming Pool and Spa Code. Permitting authority: Kirkland Planning and Building Department. Governing sections: KMC 21.06.078, .205, .215(1)(K).
Building or installing an in-ground or 24-inch-plus pool without the required permit is an unlawful act under KMC 21.06.590 and enforceable under Chapter 1.12 KMC. The building official can issue a stop work order under KMC 21.06.610 requiring work to cease immediately, plus a special investigation fee under 21.06.620, and can withhold approval until the pool is brought into ISPSC compliance and inspected.
Fencing & Safety Requirements
Kirkland requires a fence or barrier at least forty-eight inches tall around any private pool, hot tub or spa deeper than twenty-four inches, under KMC 21.41.303(b). Gates must be self-closing and self-latching, and openings can't pass a four-inch sphere. A spa with an ASTM F1346 safety cover is exempt from the fencing rule.
Key details: Trigger depth: Water over 24 inches deep. Barrier height: At least 48 inches. Opening size: No 4-inch sphere passage. Gate hardware: Self-closing and self-latching. Exemption: ASTM F1346 safety cover.
A missing, undersized or non-self-latching pool barrier is a Property Maintenance Code violation the code official can cite under KMC 1.12: a notice and order of civil violation, then civil fines of $100 per day for the first fifteen days, rising to $250 and then $500 per day the longer it goes uncorrected, capped at $50,000. Removing or weakening an existing enclosure is itself a violation, and owners get 21 days to appeal to the hearing examiner.
The Bottom Line
Kirkland's swimming pools & spas rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Kirkland is broadly strict or permissive.
