How to apply for permits and how the permitting process works

These webpages are meant to help you decide if you need a permit. To find more information about how to apply for a permit and to get required forms, search Portland.gov for the home repair or project type. For example, "ADU permits" or "Deck permits." You can also read through the full list of all building permits webpages or trade permits webpages for information about requirements for home repair permits and commercial projects. And, visit the commercial permits and inspections area or the residential permitting area of Portland.gov. 

You might also want to read more about what you need for a building permit and the permit review process. 

Why you need permits

  • It’s the law. State Building Code requires that permits be obtained for certain types of work. Permits provide a legal record of work performed.
  • Permits protect you, your family, your business and your investment. (They are designed to help ensure that licensed contractors do the work when required.)
  • Inspections ensure that work is done safely and that it meets the minimum code requirements.
  • Minor problems that could lead to costly repairs, liability and life/safety issues can be detected during permit inspections and brought to your attention before the situation worsens.
  • When selling a property, the buyer, realtor and/or lender may require that unpermitted work be corrected, properly permitted and inspected before closing.
  • Lack of permits and inspection approvals may void insurance.

Where you can get a permit

You can apply online for a permit or drop off plans in person with an appointment

Who can do the work

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. Plumbing and electrical contractors have additional license requirements. If you are a homeowner doing the work yourself, then you can sign the trade permit applications. You cannot do electrical work yourself. You must hire a licensed electrical contractor to do any electrical work.
