King County, WA Building Safety: Elevator Maintenance (2026)

Elevator safety in King County is regulated at the state level by the Washington Department of Labor and Industries (L&I) Elevator Section under RCW 70.87 (Elevators, Lifting Devices, and Moving Walks) and WAC 296-96. All elevators, escalators, dumbwaiters, wheelchair lifts, and moving walks in Washington require a state operating permit from L&I, which must be renewed annually. L&I inspectors perform annual safety inspections. Owners are responsible for maintenance performed by L&I-licensed elevator contractors and mechanics. The American Society of Mechanical Engineers (ASME) A17.1 Safety Code for Elevators and Escalators is adopted by reference. Annual inspection items include car enclosures, doors and interlocks, brakes, ropes and cables, limit switches, emergency communication devices, fire service operation, and machine room conditions. Deficiencies must be corrected within a specified timeframe. Private residence elevators (single-family homes) are exempt from state operating permit requirements but must still be installed according to code. Condominium and apartment elevators are not exempt. Installation of new elevators requires a King County building permit in addition to the L&I elevator permit. Seattle and other incorporated King County cities may have additional permitting but follow the same L&I state inspection program. Major repairs and alterations also require L&I approval. Modernizations bringing elevators to current code are not typically required unless triggered by specific conditions.
