What Permits Are Required for a Walk-In Shower Conversion in Portland, OR?

Most walk-in shower conversions in Portland require a plumbing permit at a minimum. If the project involves moving walls, adding or relocating electrical fixtures, or changing the bathroom's footprint, additional permits may be required, and the exact requirements depend on the scope of the work. Working with a full-service general contractor in Portland, OR, means permit coordination is handled as part of the project rather than something you have to figure out on your own.

CM&D is a Portland-area general contractor and design-build firm operating under Oregon CCB #112648 since 1996. Permits are part of every project they take on, and below is a breakdown of what typically applies to a walk-in shower conversion.

What Counts as a Walk-In Shower Conversion

A walk-in shower conversion typically means replacing a tub-shower combo or standard shower enclosure with a barrier-free or low-threshold walk-in shower. The scope of that replacement determines what the city requires.

A simple swap on the same footprint, with no plumbing relocation and no electrical changes, may require only a plumbing permit. Anything beyond that brings in additional requirements.

Plumbing Permits

A plumbing permit is required any time supply or drain lines are modified. Since nearly every shower conversion touches the drain connection, a plumbing permit applies to almost all of these projects.

Portland plumbing permits are issued through the Bureau of Development Services. Your licensed contractor pulls this permit before work begins and schedules the required inspections.

Electrical Permits

An electrical permit is required if the project adds or relocates a GFCI outlet, installs or moves an exhaust fan, or includes in-floor radiant heating. Bathrooms already have code requirements around electrical placement near water, so any changes trigger a separate permit.

Building Permits

A building permit is required if the conversion involves moving walls, altering framing, or changing the structural layout of the bathroom. This is common when a tub is being removed, and the alcove is being reconfigured into an open shower space.

If the shower conversion is part of a broader bathroom remodel, all applicable permits for the full scope are pulled together.

Who Pulls the Permits

In Portland, the licensed general contractor pulls permits on behalf of the homeowner. This is part of what it means to hire a CCB-licensed contractor.

We manage the full permit process on every project, from the initial application through scheduled inspections and final sign-off. You do not have to track down the permit office or figure out which type applies to your specific scope.

What Happens Without a Permit

Work done without required permits creates real prblems. Unpermitted bathroom work can affect your homeowner's insurance coverage for that work. It must be disclosed when you sell, and it can delay or complicate financing. If a future buyer's inspector finds it, you may be required to open walls and bring everything up to code before closing.

A licensed contractor will not skip permits to save time. If someone offers to do the work without pulling permits, that is a reason to walk away.

How We Handle the Permit Process
