|---|---|---|---|---|---|
city | Depends on scope | The City of Bellevue issues electrical permits. Like-in-kind replacement in the same location needs none: devices, plugs, motors and appliances rated 50 A or less, and breakers or switch parts at any rating; nor do low-voltage, phone and data wiring in the house. New circuits, a panel, a new hard-wired fixture or appliance, or replacing a whole unit such as an electric furnace or heat pump, does. A permit is required for adding or moving electrical circuits and for changes to the service panel. Bellevue issues its own electrical permits (not WA L&I); permits without plan review can issue same day but still require inspection. | — | — | Cite verified 2026-05-29 |
city | Depends on scope | Electrical work needs a permit from the City of Federal Way, not L&I, except the state's minor like-in-kind list (and temporary decorative lighting). Federal Way issues its own electrical permits — through the City's Building Division, not WA L&I. Electrical work requires a permit except minor work — replacement of branch-circuit overcurrent devices and minor electrical repair (replacing lamps, connecting approved portable equipment) are exempt. Federal Way adopts NEC 2023. The city of Federal Way electrical code (FWRC 13.38) adopts the NEC, chapter 19.28 RCW and chapter 296-46B WAC, and beyond the state's exempt list (WAC 296-46B-901(7)(b)) also exempts temporary decorative lighting, temporary wiring in experimental laboratories and temporary stage-set wiring (FWRC 13.38.040(2)). | — | — | Cite verified 2026-09-25 |
city | Always | Electrical work needs a permit, issued by WA L&I rather than the City. Electrical work requires a permit, but in Issaquah electrical permits are reviewed and issued by the Washington State Department of Labor & Industries, not the City. | — | — | Cite verified 2026-05-29 |
city | Depends on scope | Essentially all electrical work needs a permit. The only exemption is like-in-kind replacement on the L&I minor list — and an exempt job still needs an inspection request. Altering an electrical system requires a permit, but Kent does not issue residential electrical permits — those are issued and inspected by Washington State Labor & Industries. | — | — | Cite verified 2026-05-29 |
city | Depends on scope | Electrical work needs a permit from the City of Kirkland, not L&I. Like-in-kind replacement of breakers, fuses, switches, dimmers, receptacles, luminaires, thermostats, heating elements, household appliances, control components or a motor of 10 hp or less is exempt at any rating; other fixed equipment and receptacles replaced like in kind are exempt at 50 A or less; removing wiring is exempt. None of it is exempt in a flood hazard area, a critical area or its buffer, or a wildland-urban interface (WUI) location. Kirkland issues its own electrical permits — from the City's building official, not WA L&I. KMC 21.06.205 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 KMC 21.06.210 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." Kirkland adopts the Washington Cities Electrical Code as the Kirkland Electrical Code (KMC 21.70.010). Exempt under KMC 21.06.215(2) include portable cord-and-plug equipment, temporary decorative lighting for up to 90 days, and 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. Those exemptions do not apply in areas of flood hazard, in city land use critical areas and their required buffers, or where the International Wildland-Urban Interface Code applies (KMC 21.06.215). | — | — | Cite verified 2026-09-25 |
city | Always | The City of Mercer Island, not L&I, issues electrical permits, and its code exempts no electrical work: any installation, repair, replacement or maintenance of wiring or electrical equipment needs one. Mercer Island issues its own electrical permits — from the City's building official, not WA L&I. MICC 17.14.010 §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 §105.1.2 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." Mercer Island adopts the Washington Cities Electrical Code, Parts 1 and 3 (MICC 17.13.020), and its list of work exempt from permit (MICC 17.14.010 §105.2) has building, mechanical and plumbing items but no electrical ones. | — | — | Cite verified 2026-09-25 |
city | Depends on scope | Electrical work needs a permit from the City of Redmond, not L&I. Class A basic electrical work, like-in-kind replacement on the state's list, needs none. Redmond issues its own electrical permits — through the City's permit center, not WA L&I. The City's Electrical/Mechanical/Plumbing Permit page lists "New or altered electrical circuit, panel, or service" among the projects that need a permit and takes residential electrical applications online through the Redmond ePermitting Service (REPS). Redmond's electrical code applies the City's building-code administrative provisions to electrical work (RMC 15.12.050, NEC 90.4(A)) and makes electrical work "for which an Electrical Permit is required by this Code … subject to inspection by the Building Official" (NEC 90.4(C)). No permit is required for Class A basic electrical work as defined in RCW 19.28.006 (RMC 15.08.060) — the state's list of like-in-kind replacements. | — | — | Cite verified 2026-09-25 |
city | Depends on scope | Electrical work needs a permit from the City of Renton, not L&I. Like-in-kind replacement in the same location is exempt for devices, fixtures and appliances rated 50 A or less, and at any rating for breakers, fuses, switch parts and the items on the 105.2(d)(xiv) list (household appliances, luminaires, receptacles, thermostats, motors of 10 hp or less and the like); so are removing wiring and telecommunication outlets in a dwelling unit. None of it is exempt in a flood hazard area or a critical area. 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. | — | — | Cite verified 2026-09-25 |
city | Depends on scope | The City of Sammamish, not L&I, issues electrical permits. Like-in-kind repairs and replacements in the same location need none when rated 50 A or less, and neither do like-in-kind breakers, lamps, luminaires and the other items on the City's list; new circuits, a panel, a new hard-wired fixture or appliance, or other wiring work does. Sammamish issues its own electrical permits — through the City's permit center and Building Division, not WA L&I. SMC 16.20.197 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."

city | Depends on scope | Electrical work needs an SDCI electrical permit, except like-in-kind replacement of up to five light fixtures, switches, dimmers, receptacles or lamps, branch-circuit breakers and similar controls, a household appliance on its existing circuit, or one motor of 10 hp or less; a listed heat mat set in tile grout; and communication wiring in a house. A sixth fixture or a new circuit needs one. Electrical permit required for ALL electrical work in residential. Seattle runs its own electrical program: SDCI issues AND inspects electrical permits inside city limits (NOT L&I — L&I only handles contractor licensing). Most residential work is issued over the counter, same day, online through the Seattle Services Portal; OTC eligible under 5,000 sf or under 400 A. Plan review only per Seattle Electrical Code Art. 80 §80.50/80.51. | — | — | Cite verified 2026-07-27 |

city | Depends on scope | Electrical work needs a permit — from Tacoma Power where it serves the property, from L&I elsewhere; the City issues neither. Like-in-kind replacement on the issuer's exempt list is exempt. Who issues an electrical permit in Lakewood depends on the property's electric utility: Tacoma Power where Tacoma Power serves it, WA L&I elsewhere. The City of Lakewood issues neither. Lakewood adopts the NEC as adopted in chapter 296-46B WAC and chapter 19.28 RCW, "except that “Department” shall mean either the State Department of Labor and Industries or Tacoma Public Utilities, depending on geographic service area located within Lakewood’s City limits" (LMC 15.05.020(I)). The City's permit page: "Sewer, water, electrical, and fire safety permits, reviews, and inspections are done by outside agencies." Lakewood's electric utilities are Tacoma Power, Lakeview Light & Power and Puget Sound Energy (City of Lakewood, Local Utilities). Both issuers exempt only like-in-kind replacement of the items on their own lists (Tacoma Power under TMC 12.06A.210; L&I under WAC 296-46B), and where L&I issues, an exempt job still needs an inspection request. | — | — | Cite verified 2026-09-25 |
city | Depends on scope | Essentially all electrical work needs a permit; only like-in-kind replacement on the L&I minor list is exempt. WAC 296-46B (WA-adopted 2020 NEC) requires an electrical permit for essentially all electrical work. L&I issues them in most jurisdictions; some cities run their own program. L&I publishes the exemption list, and it is narrower and more specific than "ordinary repairs": travel trailers; plug-in household appliances; and the LIKE-IN-KIND replacement of lamps, a single set of fuses, a single battery under 150 amp-hour, control components such as contactors, relays, timers, starters and circuit boards, one household appliance, circuit breakers (branch-circuit overcurrent protection only, per NEC 100), single-family residential luminaires, up to five snap switches, dimmers, receptacle outlets, thermostats, heating elements or identical luminaire ballasts, sign and outline-lighting components replaced on-site by an electrical contractor without modifying the system, and one motor of ten horsepower or smaller. AN EXEMPTION FROM THE PERMIT IS NOT AN EXEMPTION FROM INSPECTION: L&I requires an inspection request before any electrical work is covered, no later than 3 business days after the work is finished or 1 business day after any part is energized, whichever comes first, and failure to request one can carry civil penalties. | — | — | Cite verified 2026-04-29 |
city | Depends on scope | Electrical work needs a permit from Tacoma Power, not the City's permit center or L&I. Like-in-kind replacement of breakers, fuses, light fixtures, lamps, switches, dimmers, outlets, thermostats, heating elements, household appliances or a motor of 10 hp or less is exempt, any number of them, as are heat cable repair and embedding a listed, factory-wired heat mat in tile grout; panel or service work is not. In Tacoma, electrical permits are issued and inspected by Tacoma Power (Tacoma Public Utilities), not WA L&I and not the City's Planning & Development Services. Tacoma's electrical code, TMC chapter 12.06A, applies "in areas served by the City, by and through its Department of Public Utilities, Light Division" (TMC 12.06A.030), and its Chief Electrical Inspector "shall, upon submission of a permit request, issue Permits for the installation or alteration of electrical wiring, devices, appliances, and equipment" (TMC 12.06A.080). The City's permit site lists Tacoma Public Utilities (TPU) Power as the agency for "All electrical permits, power service connections, and power infrastructure." TMC 12.06A.210 requires an electrical permit "for the installation, alteration, or maintenance of all electrical systems or equipment", except like-in-kind replacement of a control component, household appliance, circuit breaker, fuse, residential luminaire, lamp, snap switch, dimmer, receptacle outlet, thermostat, heating element, identical luminaire ballast, sign components where the system is not modified, or a motor of 10 horsepower or smaller; induction gate-control loops; heat cable repair; and listed heat mats embedded in tile grout. | Electrical permit fees are Tacoma Power's, set in TMC 12.06A.250 — for example $89 for one to four new or altered branch circuits where the service is not modified, two inspections included — not an L&I fee. | — | Cite verified 2026-09-25 |

city | Depends on scope | Electrical work needs a permit from the City of Everett, not L&I. Replacing existing equipment in kind, of any number and with nothing added, is exempt. Everett runs its own electrical permit program: electrical permits in the City of Everett are issued by the City's Building Official through Everett Permit Services, not by WA L&I. Everett's amendment to the National Electrical Code (EMC 16.05.010, Article 80-11(a)) bars anyone from installing, altering, replacing or extending electrical work or equipment "without first obtaining a separate electrical permit for each installation, alteration, replacement or extension from the Building Official", except replacement in kind and IBC 105.2.1 emergency repairs. Everett's permit-exemptions handout for one- and two-unit dwellings (rev. 10/07/2025) lists the exempt electrical work: listed cord-and-plug temporary decorative lighting; reinstalling attachment plug receptacles (but not the outlets); replacing branch-circuit overcurrent devices of the required capacity in the same location; wiring and equipment operating at less than 25 volts and not capable of supplying more than 50 watts; and minor repair such as replacing lamps or connecting approved portable equipment to permanently installed receptacles. Generators are on the handout's list of work that does need a permit. | — | — | Cite verified 2026-09-25 |
city | Depends on scope | Electrical work needs a permit from the City of Lynnwood, not L&I. The City's exemptions handout lists like-in-kind replacement of a breaker, switch, dimmer, outlet, light fixture, lamp, appliance, thermostat and similar parts as exempt. Lynnwood issues its own electrical permits — through the City's Development & Business Services, not WA L&I. The City's Electrical Permits page: "The City of Lynnwood issues Electrical Permits and conducts inspections for work done within Lynnwood City Limits." and "An electrical permit is required for most electrical work and ensures your installation conforms to safety codes and standards." Lynnwood adopts "the Washington State adopted National Electrical Code (NEC)" (LMC 16.10.050) and sets electrical permit fees by city fee ordinance (LMC 16.10.090); the chapter's own exempt-work section, LMC 16.10.065, is repealed. The City's "Electrical Permit Exemptions" handout (Building Permit Series, 2024.06) lists the "work which does not require a permit per the Lynnwood Municipal Code, RCW 19.28, WAC 296.46B, NEC and TIA/EIA standards": like-in-kind replacement of a circuit breaker, dimmer, fuse, heating element, household appliance, lamp, luminaire ballast with an exact same ballast, receptacle outlet, residential luminaire, snap switch, thermostat, motor of ten horsepower or smaller, control component (contactor, relay, timer, starter, circuit board), or sign and outline-lighting components where the system is not modified; induction gate-control loops; heat cable repair; listed heat mats embedded in tile grout; telecommunications installations inside single-family, duplex and multifamily dwelling units; cord-and-plug telecommunications equipment; and travel trailers. It does not cover replacing a whole unit, assembly or enclosure that contains an exempt component, such as an electric furnace or heat pump. | — | — | Cite verified 2026-09-25 |
