Portland Retaining Wall Right-of-Way Permit Fee: The $1,332 Line Item

Portland’s transportation review schedule lists a $1,332 fee for a private retaining-wall encroachment in the public right-of-way. It also lists structural review at $325. Read the July 10, 2026 schedule.

If the city confirms both lines apply, the known municipal subtotal is $1,332 + $325 = $1,657. The schedule does not make structural review automatic for every wall, so confirm it before using that subtotal.

A wall fully on private property may use another permit path. Ask for the property line, wall location, height, drainage, engineered drawings, and whether transportation and building review are required. Excavation and construction remain separate. The fee schedule was checked September 8, 2026.

Request city confirmation of the encroachment category before letting a contractor bury the $1,332 line in a general wall allowance.

A property-line sketch is the quickest eligibility check. If the wall occupies the right-of-way, identify the encroachment area and submit height, location, drainage, and engineering information so the $325 review question is answered before construction.

Compare the city fee with the project boundary, not with a private retaining-wall quote. A wall set back behind the property line may need building or grading review without the right-of-way encroachment line; a wall over the line can require transportation review even if the wall itself is small. Ask Portland to classify the location in writing and have the contractor quote engineering, excavation, drainage, and restoration separately from the $1,332 municipal line.

If the wall sits entirely on the lot, do not carry the right-of-way number into the bid simply because the project is near a street. If it crosses the line, the encroachment fee can be decisive even before concrete and drainage are priced. Attach the property survey and wall section to the city inquiry and retain the response with the permit application.

Portland’s retaining-wall page says a wall over four feet high or affected by a nearby slope, driveway, or structure needs a building permit, and public-right-of-way work receives a separate transportation permit. Read the city’s retaining-wall requirements before treating the $1,332 encroachment line as the only permit question.
