If you’re installing, altering, extending, or connecting electrical wiring anywhere in Seattle, you almost certainly need a Seattle electrical permit from the Seattle Department of Construction and Inspections (SDCI) before the work begins.1Seattle Department of Construction and Inspections. Electrical Permit The permit is only half the requirement; the work also has to pass inspection before it’s considered legally complete.
When a Permit Is Required
The rule is broad: any time wiring is installed, altered, extended, or connected to electrical equipment (including signs), you need a permit.1Seattle Department of Construction and Inspections. Electrical Permit New branch circuits, service panel upgrades, kitchen remodels, hardwired EV chargers — all permit work. If you’re adding something that wasn’t there before or changing a circuit’s capacity, assume you need to pull a permit.
The main exception is like-in-kind replacement. Seattle Electrical Code Section 80.50(B) lets you swap out specific items without a permit as long as the replacement is an identical-type component. The list includes dimmers, thermostats, water heaters, and baseboard heaters.2Seattle Department of Construction and Inspections. Electrical Permits and Inspections Frequently Asked Questions Replacing a standard light switch or wall outlet generally falls in the same bucket. Some small low-voltage systems may also be exempt, but SDCI directs owners to Sections 80.50 and 80.51 of the Seattle Electrical Code to confirm whether a specific project qualifies.1Seattle Department of Construction and Inspections.

Who Can Pull the Permit
If you own the property, you can pull your own electrical permit and do the work yourself. Washington state law under RCW 19.28.261 allows unlicensed individuals to perform electrical work at a residence, farm, or business they own, and there’s no requirement that it be your primary residence.3Seattle Department of Construction and Inspections. 2023 Seattle Electrical Code Quick Reference The permit and inspection requirements still apply; only the licensing requirement is waived.
If someone else is doing the work, they must be a licensed electrical contractor. Anyone applying for electrical permits in Seattle needs both a Washington State electrical contractor’s license and a Seattle business license.1Seattle Department of Construction and Inspections. Electrical Permit You can verify a contractor’s license through the Washington State Department of Labor and Industries.4Washington State Department of Labor and Industries. Verify a Contractor, Tradesperson or Business If your plans change mid-project, SDCI allows you to add or remove a contractor from an existing permit.2Seattle Department of Construction and Inspections. Electrical Permits and Inspections Frequently Asked Questions
How to Apply
Applications go through the Seattle Services Portal.5Seattle Services Portal. Permits, Licenses and Regulatory Compliance You’ll need the project address, a description of the work, the number of circuits and fixtures involved, and whether the project is new construction or an alteration. If a contractor is doing the work, their Washington State electrical contractor license number goes on the application.
SDCI issues many electrical permits the same day you apply online, as long as no plan review is required.1Seattle Department of Construction and Inspections. Electrical Permit Smaller residential projects and simple alterations usually qualify for this over-the-counter process.
Larger or more complex projects require plan review, which means submitting load calculations, wiring diagrams, and detailed specifications through the portal. Turnaround depends on how clean your submission is and how backed up the queue is. If load calculations aren’t your thing, a licensed electrician or engineer can prepare the technical documentation for you.
What a Permit Costs
For projects that require plan review, Seattle’s fees are based on the total valuation of the electrical work. Under the 2026 fee schedule, a project valued at $1,000 or less costs $260. From there the fees scale: a job valued between $1,001 and $5,000 runs $260 for the first $1,000 plus $6 per additional $100 of value, putting a $5,000 job at roughly $500. A $25,000 project reaches about $1,050.6Seattle Department of Construction and Inspections. 2026 Fee Subtitle
Permits that don’t require plan review are issued same-day and typically cost less, though the exact amount depends on the scope of work. Payment is by credit card or electronic check through the Seattle Services Portal.
Inspections Close the Permit
A permit alone doesn’t finish the job. Every permitted electrical project must pass at least one inspection, and most require two: a cover inspection and a final inspection.7Seattle Department of Construction and Inspections. Electrical Inspections
The cover inspection, sometimes called the rough-in, has to happen before any wiring gets concealed behind walls, ceilings, insulation, or concrete. Don’t cover any work with insulation, receptacles, or wall switches until the inspector signs off.7Seattle Department of Construction and Inspections. Electrical Inspections
The final inspection comes after everything is done, with panels covered, circuits labeled, cover plates installed, and equipment grounded and energized. Passing the final closes the permit and makes the installation legally compliant.
To schedule an inspection, call SDCI’s 24-hour inspection request line at (206) 684-8900 or book through the Seattle Services Portal.7Seattle Department of Construction and Inspections. Electrical Inspections If an inspector has to come back more than once because work failed, additional re-inspection fees may apply.
How Long the Permit Lasts
Construction, demolition, mechanical, and grading permits in Seattle typically expire 18 months after the issue date.8Seattle Department of Construction and Inspections. Building Permit Renewals If your project is still ongoing, you can renew up to 30 days before expiration. If the permit has already expired but less than a year has passed, you may be able to reestablish it. Let it lapse beyond that window and you’ll be starting the application over.
Penalties for Skipping the Permit
Working without a permit is one of the most expensive shortcuts you can take. Washington’s penalty schedule charges $250 for a first offense of beginning an installation or alteration without a permit, $1,000 for the second, and $2,000 for each one after that.9Washington State Legislature. WAC 296-46B-915 SDCI can also issue stop-work orders that halt the whole job site until the violation is resolved.
There’s one narrow exception. For emergency repairs to an existing electrical system, you avoid the penalty if you obtain and post the permit by the next business day.9Washington State Legislature. WAC 296-46B-915 That exception doesn’t cover new installations or work that isn’t genuinely urgent.
Fines aren’t the only cost. Unpermitted electrical work shows up at resale, and a home inspection or title search that uncovers it can kill a deal or force you to open walls and retroactively permit the job at your own expense. Pulling the permit at the start is almost always cheaper than cleaning up after not pulling one.
