Kirkland, WA Swimming Pools & Spas: Above-Ground Pools (2026)

Kirkland treats above-ground pools the same as in-ground pools once water depth exceeds 24 inches. A building permit is required through the Kirkland Building Division, along with an electrical permit for pump and heater connections. Plans must show the location of the pool on the lot, distances from property lines and structures, and details of the barrier. Above-ground pools may use the pool wall as the required barrier when the wall itself is at least 48 inches high and meets the non-climbable standards in the International Swimming Pool and Spa Code. Any access ladder must be removable when not in use or permanently enclosed by a self-closing, self-latching gate that raises the ladder to an inaccessible position. The deck or platform around an above-ground pool must have a separate 48-inch barrier if the deck is at or below the top of the pool wall. Setback and stormwater rules in Kirkland Zoning Code Chapter 115 still apply, and pools on sloped lots or near critical areas may need geotechnical review. Backwash and pool drainage water must be discharged to the sanitary sewer with a utility approval, not to the storm drain, to comply with Kirkland Surface Water Utility rules. Many pre-packaged above-ground pool kits include installation guides that conflict with Washington code, so owners should have a licensed contractor or the Building Division review the plan before ordering.
