Permit Fees in Portland, OR

Portland requires separate permits for each trade. You file for building, plumbing, electrical and mechanical work individually. No single master permit here.

The building side uses a valuation formula. The minimum fee sits at $153. Jobs from $501 to $2,000 add $3.29 per $100 of value. I had to cross reference three pages in the Portland Building Permit Fee Schedule effective July 1 2025 to map this out. Plan review adds 65 percent of that building fee every time.

Plumbing runs on a per fixture basis. Most fixtures cost $60 each. A four fixture bathroom hits $240 before any surcharge. New homes get package pricing instead. One bath costs $754.

Electrical follows state rules under OAR 918-309. Homes 1,000 square feet or less pay $388. This covers the garage and service. Panel upgrades start at $201.

Mechanical permits use a per item list with a $153 minimum. A furnace replacement costs $83 but the minimum often wins. The city doesn't let small jobs slide.

Every fee gets the 12 percent Oregon state surcharge. No exceptions. That $1,070 subtotal on a bathroom becomes $1,199. The calculator on this page handles the math for you. Plug in your numbers and see what happens.

Most changes to your home need a permit in Portland. Bathroom remodels require building plumbing electrical and mechanical approvals. Kitchen updates follow the same pattern.

Do you need a permit in Portland to build a deck? Yes. Same for roof replacement or finishing a basement. A water heater swap needs a plumbing permit. Window replacement might not if you keep the same size opening but check first.

The fee schedules don't list every exemption. You can't assume your shed or fence is clear. Portland Permitting and Development decides.

Skipping permits creates real problems, and Neighbors complain. Future sales get complicated. The city finds out more often than people expect.

Portland charges an investigation fee for work started without permits. The minimum is $153 per hour. This comes from page 6 of their compliance programs document.

They don't waive this fee. The clock starts when they discover the job. You still must pull the permit afterward and pay normal fees on top.

The math doesn't work in your favor. One hour turns into several quickly. Nobody wins when the building department shows up unannounced.

Portland permits don't last forever. You can request an extension but it costs $217 per hour with a one hour minimum. This applies to inactive permits.

Expired permits require reactivation. The fee equals half the new permit cost with a $217 minimum. You only get one renewal.

Plan your timeline carefully. File early and stay active. The city doesn't give free extensions.

The fee schedules don't spell this out clearly. Contractors normally pull permits in Portland. This keeps the legal responsibility on them.

Oregon lets homeowners pull permits for their own primary residence. You must follow all the rules and hire licensed trades for electrical and plumbing work.

Check your contract. If the contractor wants you to pull it that raises a red flag. Your contractor should handle this.

Oregon adds a 12 percent surcharge to every single permit fee in Portland. State law requires it. The city collects the money and passes it along.

This applies to building plumbing electrical and mechanical permits. A $60 plumbing fee becomes $67.20. The surcharge never disappears.

I noticed this when comparing schedules across states. Not every place has this extra layer. It makes Portland projects cost more than they first appear. The calculator includes it automatically so you see the real number.
