Even if a building permit is not needed, the work will need an plumbing permit.
Adding a bathroom needs a plumbing and building permit, and may also need an electrical and/or mechanical permit. For new townhouse projects, each unit needs an electrical permit. To remove on-site sewage disposal system (cesspool or septic tank, you need a decommissioning permit.
You do not need a plumbing permit to:
- Fix, replace, or maintain an appliance or parts already in place.
- Replace related plumbing parts that do not need water (toilet seat).
If unsure, call Residential Inspections to ask an inspector.
Who can do the residential plumbing work
If not doing the work yourself, you can hire a contractor. Contractors must have a license to work in Oregon. The Oregon Construction Contractors Board (CCB) issues licenses to contractors. The permit application and their company materials must list the license number. Need help finding a contractor? The CCB website has good tips on how to search for one.
All plumbing contractors must have a license from the Oregon State Plumbing Board (PB).

The fees are listed on the plumbing permit application. They are based on the fixtures and the work being done.

Get the results of the inspection online by searching for your permit on Portland Maps on the following day.
Not approved - there are many reasons why the work did not get approved:
- no access - the inspector may not have been able to inspect the work
- incomplete work
- code violations
The inspector will list the corrections needed on the inspection report.
Call for a reinspection after making the corrections. Use the same three digit inspection code.
If you make the corrections the same day wait until 5 pm to request a reinspection. The inspector needs to enter their results before you can schedule the reinspection.
There is a reinspection fee charged for more than one reinspection for a single issue.
Contact plumbing inspectors
If you have questions before your inspection, you can talk to an inspector. The inspectors' name, region, and phone numbers are listed on the the 1 & 2 family inspector area map.
Because of vacation or illness, your inspector may be different than the one listed on the map. If you have questions after your inspection, find out which inspector to call. Their contact information will be on the inspection results and on Portland maps.
