When does electrical work need a permit in Renton?
Renton issues its own electrical permits — from the City's Building Official, not WA L&I. RMC 4-5-060 §105.1 requires anyone who intends to install, alter, repair, remove, convert or replace any electrical system to "first make application to the Building Official and obtain the required permit", and §105.1.3 requires an electrical permit, in accordance with chapter 19.28 RCW, for "The installation, alteration, repair, replacement, modification or maintenance of all electrical systems, wire and electrical equipment regardless of voltage." Renton adopts the Washington Cities Electrical Code as the Renton Electrical Code (RMC 4-5-040). Exempt under RMC 4-5-060 §105.2 (Electrical): like-in-kind repair or replacement in the same location of fixed motors, transformers, appliances and devices rated 50 amps or less, of current-carrying parts of switches and control devices, of plugs and receptacles rated 50 amps or less, and of overcurrent devices; like-in-kind replacement of a circuit breaker, fuse, residential luminaire, lamp, snap switch, dimmer, receptacle outlet, thermostat, heating element or household appliance; portable cord-and-plug equipment; temporary decorative lighting for up to 90 days; and removal of electrical wiring.
