Summary
Renton requires private residential pools, spas and hot tubs to comply with the International Swimming Pool and Spa Code, adopted by reference at RMC 4-5-060(A)(6)(m). Public and semi-public pool barriers instead follow the State Board of Health's own rule, WAC 246-260-031(4), which the local code points to directly.
m. 101.5.12 International Swimming Pool and Spa Code – Scope. The provisions of this code shall apply to the construction, alteration, movement, renovation, replacement, repair and maintenance of aquatic recreation facilities, pools and spas. ... Swimming pools, spas and other aquatic recreation facilities shall comply with the International Swimming Pool and Spa Code, where the facility is one of the following: i. For the sole use of residents and invited guests at a single-family dwelling; ii. For the sole use of residents and invited guests of a duplex owned by the residents; or iii. Operated exclusively for physical therapy or rehabilitation and under the supervision of a licensed medical practitioner. Public swimming pool barriers shall be regulated by WAC 246-260-031(4). All other "water recreation facilities" as defined in RCW 70.90.110 are regulated under chapters 246-260 and 246-262 WAC.

Full Breakdown
RMC 4-5-060(A)(6)(m) adopts the International Swimming Pool and Spa Code (ISPSC) by reference as part of Renton's Construction Administrative Code, and defines which pools it covers: those for the sole use of residents and invited guests at a single-family dwelling, those for the sole use of residents and guests at a duplex owned by the residents, and those operated exclusively for physical therapy or rehabilitation under a licensed medical practitioner's supervision. Those private facilities must meet the ISPSC's construction, alteration, movement, renovation, replacement, repair and maintenance standards, including the barrier, self-latching gate and alarm provisions that pool builders and installers must satisfy before the Building Official signs off on a permit.
110 are regulated under chapters 246-260 and 246-262 WAC. That means hotel pools, apartment-complex pools, and other public or semi-public facilities are inspected and licensed under the Washington State Department of Health's water recreation facility rules rather than under Renton's building code, even though the same permit process in RMC 4-5-060 governs the surrounding structure.
Violations & Fines
Building or altering a residential pool without ISPSC-compliant barriers and inspections is enforced the same as any Construction Code violation: RMC 4-5-060 lets the Building Official halt work, refuse inspection sign-off, and withhold final approval until the barrier and gate meet code. Public pools that fail to meet WAC 246-260-031(4) barrier standards face separate enforcement and licensing action from the Washington State Department of Health, not the City.
