Renton hot tubs require NEC 680 electrical permits. Unless a lockable ASTM F1346 safety cover is used, an IRC Appendix G 48-inch barrier is required. Setbacks follow accessory structure rules.
Residential hot tubs and spas are regulated in Renton through RMC 4-5-060 (IRC adoption) and RMC 4-5-070 (IFC). A building permit is required for permanently installed spas that are not listed as portable, and an electrical permit is always required for the 240V circuit and GFCI per NEC Article 680. A safety cover meeting ASTM F1346 (250 lb load rating, lockable) can substitute for a full barrier under IRC Appendix G, which is the most common compliance path for single-family hot tubs. If no compliant cover is used, a 48-inch barrier meeting the same standards as pool fencing must enclose the spa. Setbacks typically follow accessory structure rules in the applicable zone (commonly 5 feet from side and rear property lines). Wiring must be bonded per NEC 680.26 with an equipotential grid and all metal parts within 5 feet bonded. Noise from pumps and blowers must comply with WAC 173-60 limits as adopted in RMC Chapter 8-7.
Hot tub without electrical permit: stop-use, double-fee permit-after-the-fact. No cover and no barrier: RMC 1-10 civil penalty.
