Do I Need a Permit to Remodel My Bathroom?

Short answerIt depends on the work and where you live. Paint, tile and a same-place vanity often don't need a permit, while moving plumbing, changing wiring or altering walls often do. Some places require a permit for any interior remodel, so don't assume. Confirm with your local building department before you start demolition.

What the model code says

The 2015 International Residential Code, as published by Springville, Utah, exempts painting, papering, tiling, carpeting, cabinets, countertops and similar finish work. It doesn't treat changes to water, drain or vent piping or to electric wiring as ordinary repairs.

Stricter places exist

Why it's worth asking first

Portland, Oregon's 2022 permit guide says inspections catch problems early, that buyers, realtors or lenders may require unpermitted work to be corrected before closing, and that a lack of permits and inspection approvals may void insurance. Even where no permit is needed, the work generally still has to meet code and zoning rules.

Common questions

Do I need a permit to replace a bathtub?

Prince William County says only if the location of the fixture, piping or valves changes. Portland says replacing a fixture with concealed plumbing connections needs a plumbing permit. Check your local rule.

Can I remodel my own bathroom?

Many places allow owners to do some work, but the rules for electrical and plumbing differ. Portland requires you to be both the owner and occupant to do electrical work yourself. Ask when you call about the permit.
