Whether a bathroom remodel needs a permit depends on what's changing, not on how big the bathroom is. In Kirkland, the city publishes a clear list. Here's how it applies to bathroom work, and how it differs on the wider Eastside.
The short answer for Kirkland
Kirkland requires a permit for interior remodels, drywall removal or installation, adding, removing or relocating walls, and electrical circuit or service extensions or alterations. It treats like-in-kind appliance and fixture replacement, such as a toilet or sink in the same location with no change to gas lines, plumbing lines or electrical circuits, as exempt, and it exempts finish work such as painting, papering, tiling, carpeting, cabinets and countertops, as long as existing accessibility features aren't altered. When in doubt, the city's Development Services Center, at 425-587-3600, can answer questions before work starts.
Common bathroom projects and likely permit status in Kirkland
| Project | Likely status |
|---|---|
| Replace vanity top, faucet or mirror | Generally exempt as finish work or like-in-kind replacement. |
| Retile a floor or shower surround | Generally exempt as finish work, if plumbing and electrical aren't changed. |
| Replace a toilet in the same place | Generally exempt as like-in-kind replacement. |
| Remove drywall or rebuild the shower walls | Permit required, as drywall removal or installation is on the permit list. |
| Move the toilet, shower or sink | Likely required, since plumbing lines change. |
| Add a circuit for heated floors or new lighting | Required, since electrical circuit alterations need a permit. |
| Move or remove a wall | Permit required. |
| Alter existing accessibility features | Not exempt. Ask the city. |

Critical areas and shoreline lots
Kirkland states that its permit exemptions don't apply in critical areas, such as flood hazard, wetland, steep slope or shoreline zones. That matters in a city with a long Lake Washington shoreline and creeks and wetlands near Juanita Bay. If you live near the water, in Houghton, Juanita or elsewhere, check your address in the city's property search tool before assuming a finish-only project is exempt.
Electrical rules in Washington
Electrical work has statewide rules on top of city rules. Washington requires a licensed electrical contractor for installing wiring or equipment as a business, and circuit wiring needs a permit. State guidance lists replacing up to five snap switches, dimmers or receptacles like-for-like, and like-in-kind replacement of single-family luminaires, among the work that doesn't need a permit, but a project doesn't need an electrician's permit only because it doesn't need a permit; in some cases only a licensed electrician or the homeowner may do the work. Heated floors, new circuits and fan wiring fall on the permit side. See heated bathroom floors.
Other Eastside and North Seattle-area cities
Each city runs its own permit office and sets its own rules, so what applies in Kirkland may not apply across the line. If you live in Bothell, remember the city crosses the King and Snohomish county line, and addresses outside city limits follow county rules. Kenmore, Woodinville, Mill Creek and Lynnwood each have their own permit office, so ask the city before you start.
Who pulls the permit?
Usually the contractor, and it should be in the contract. Ask who applies for permits, who pays the fees and who schedules inspections. Inspections typically happen before walls are closed so plumbing and electrical can be checked. A contractor who suggests skipping a permit that your project needs puts you at risk when you sell or file an insurance claim.
