Learn more about building permits, commercial permits, electrical permits, mechanical permits, plumbing permits and zoning permits and work that requires a permit for a 1 or 2 family home. When is a permit needed?

Get information about the types of work that require a permit.

Why do 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 can you get a permit? How do you apply for a permit?

To find more information, search Portland.gov for a project type. For example, "ADU" or "Decks." You can also check out building permits or trade permits for information about specific types of permits. You can also visit the residential permitting area of The Portland.gov.
