Do you need a permit for a bathroom remodel in Portland?
When permits apply, who pulls them, and why the inspection is on your side.

Short answer
In Portland and most surrounding cities, a bathroom remodel needs permits whenever the work touches plumbing, electrical, or structure, which covers most tile shower and tub to shower projects. Purely cosmetic updates, like new paint, a vanity swap in place, or new flooring, generally do not. Your contractor should pull the permits for the work they perform.
Where a project lands in these ranges depends mostly on the finish materials you choose: tile, cabinetry, countertops, and plumbing fixtures.
Figures are nonbinding planning estimates, not a quote, bid, or offer. Actual pricing is established only by a written estimate.
Systems versus surfaces
Cities regulate the parts of a remodel that can hurt the house or the people in it: water, wiring, and structure. Replace a faucet with the shutoffs in the same place and you're redecorating. Move a drain, replace a shower valve, add a circuit for a heated floor, or open a wall, and you're doing regulated work that needs a trade permit.
In practice, that means most real bathroom remodels need at least a plumbing permit, and many need electrical as well. A tub to shower conversion changes the drain and valve, so it is permitted work essentially every time.
What typically requires a permit
- Moving or replacing drain lines, supply lines, or the shower valve.
- Converting a tub to a shower, or relocating a toilet, sink, or shower.
- New electrical circuits: heated floors, added outlets, new lighting runs, a fan where there wasn't one.
- Structural changes: removing or opening walls, recessing a curbless shower pan into the floor framing.
- Water heater replacement or relocation done as part of the project.
What usually doesn't need a permit
- Paint, trim, mirrors, and accessories.
- Swapping a vanity, toilet, or faucet in the same location, connection for connection.
- New flooring laid over a sound subfloor.
- Replacing tile in place without touching the plumbing behind it (though if the old waterproofing failed, the smart move is opening it up, which changes the answer).
Who pulls the permit
Licensed contractors pull trade permits for the work they perform; in Oregon that licensing runs through the CCB, and the permit itself through the city or county building department. When a contractor asks you to pull an owner's permit for work they are doing, that is a red flag: it shifts the liability to you and often means they can't or won't have the work inspected under their own license.
We pull the permits for everything we build, schedule the inspections, and meet the inspector. It is part of the job, not an add on, and the city paperwork never lands on your desk.
Why the inspection protects you
The inspections a bathroom permit triggers, rough plumbing, the shower pan, electrical rough in, cover exactly the work that disappears behind tile and drywall. A pan flood test witnessed by an inspector is a second set of eyes on the single most failure prone part of the room, and it costs you nothing extra.
Unpermitted work surfaces at the worst time: during a sale, when a buyer's inspector or an appraiser asks for permit history, or during an insurance claim after a leak. Retroactive permits and opened up walls cost far more than doing it in order.
Related questions
How much do bathroom remodel permits cost in Portland?
Trade permit fees are set by each jurisdiction and scale with the valuation and scope of work; for a typical bathroom remodel they are a small fraction of the project cost, usually a few hundred dollars across plumbing and electrical. We fold permit costs into our estimates so the number you see already includes them.
Do permits slow the project down?
Rarely, when they're handled early. Straightforward bathroom trade permits are often issued quickly, and inspections are scheduled to land between our work phases, the pan inspection happens while tile is being staged anyway. The delays you hear about usually come from permits pulled late, after work already started.
What happens if previous owners remodeled without permits?
It's common, especially in Portland's older housing stock, and it isn't your emergency until you remodel or sell. When we open a wet area and find unpermitted work, we bring what we touch up to current code under our permits. If you're buying a home with a suspiciously new bathroom and no permit history, budget for the possibility that the waterproofing is cosmetic.
Are the rules the same in Beaverton, Vancouver, and the suburbs?
The principle is the same everywhere in the metro: plumbing, electrical, and structural work needs permits; cosmetics don't. The specifics, fees, forms, and which county or city office issues them, vary by jurisdiction, and Vancouver follows Washington's rules rather than Oregon's. We work across both states and handle each city's process as part of the job.
