Portland, Oregon Building Permit Guide

Portland is the largest city in Oregon at about 635,000 residents, spanning parts of Multnomah, Washington and Clackamas counties. Building permits are issued by Portland Permitting and Development (PP&D) — the consolidated bureau that manages building permits, land use, inspections, code enforcement and public-works permits — from offices at 1900 Southwest Fourth Avenue.

This guide covers Portland Permitting and Development and how to reach it, the uniform statewide code, Cascadia seismic and land-use review that sit alongside a permit, and how fees and inspections work.

This guide covers work inside the City of Portland limits. Multnomah County and the neighbouring cities — Gresham, Beaverton, Lake Oswego — are separate authorities.

What requires a building permit in Portland?

Which code applies — OSSC or ORSC

The Oregon Residential Specialty Code (ORSC) governs one- and two-family dwellings and townhouses and their accessory structures; the Oregon Structural Specialty Code (OSSC) governs commercial buildings, apartments of three or more units and everything outside the residential scope. Alongside them sit the mechanical, plumbing, electrical and energy specialty codes, and the Oregon Fire Code is adopted by the State Fire Marshal. In Portland, the city’s bureau administers the state code alongside the city’s own land-use, historic and environmental overlays, which frequently drive the schedule.

Oregon’s building code and its exemptions are the same in Portland as everywhere in the state, and an exemption from the building permit is not an exemption from zoning, land use or a trade permit. Site snow, wind and seismic values come from the state’s Oregon Design Criteria Hub. How Oregon’s statewide code works

Who handles permitting in Portland?

Portland Permitting and Development handles plan review, permit issuance, inspections, land use and code enforcement inside the city.

Portland Permitting and Development reviews plans, issues permits, performs inspections and administers land use and code enforcement in one bureau. Because Portland carries extensive historic, design and environmental overlays, the land-use side often drives the timeline more than the building code — a certificate or land-use review that clears ahead of the building permit is a common cause of delay when left late.

The technical code is the uniform state code, so what Portland adds is the overlay and land-use layer, the fee schedule and the inspection process.

In 2025, building permits issued in Portland authorized 1,223 new privately owned housing units, 703 of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.

Permit types

Residential permits

Residential work spans dense infill, additions, accessory dwelling units and historic-district rehabilitation. Re-roofs beyond the exempt scope, solar and EV chargers need permits, seismic detailing applies broadly, and every contractor needs a current CCB licence, apart from casual work under $1,000 and owners working on their own property.

Commercial permits

Commercial work runs from downtown and mixed-use towers to industrial and institutional projects, all subject to plan review, land-use and design review, and the CCB licence requirement, with electrical and plumbing work generally done by state-licensed trades.

Contractors need a current Construction Contractors Board licence with the right endorsement for a job of any size; the exceptions are casual work under $1,000 by someone who does not advertise as a contractor, and owners working on their own property who are not building to sell.

Portland permit costs and fees

Budget the city building permit and plan-review fees, the statewide surcharge, separate trade permits, and any land-use, design or historic review a parcel triggers. Fees follow Oregon’s statewide valuation method with the city’s schedule.

Oregon fixes the method rather than the price: new construction is valued with the ICC building valuation data under OAR 918-050-0100, Portland applies its own schedule, and a 12 percent state surcharge is added to every permit fee. How Oregon permit fees are set

Trade permits and who may pull them

Electricians and plumbers are licensed by the state, though an owner may do electrical work on their own home and plumbing work that is not for hire. An electrical permit is needed for new or altered wiring; like-for-like repairs of outlets, switches and fixtures, and bulb, fuse and small-appliance swaps, are exempt.

How to apply for a Portland building permit

An Oregon building permit expires if work does not start within 180 days of issue or stops for 180 days; the building official can extend it in writing, 180 days at a time. Oregon’s statewide code rules

Inspections in Portland

Standard checkpoints include footing and foundation, under-floor and slab, framing, rough-in electrical, plumbing and mechanical, insulation and energy, fire systems on commercial work, and final, with occupancy approval before use. Historic and environmental-overlay work adds condition and mitigation verification.

Many Oregon jurisdictions take inspection requests online, several through the state ePermitting system; confirm the method Portland Permitting and Development uses and give the notice it asks for.

Do not cover work before the required inspection has been approved. Keep the issued permit, the approved plans, the seismic and energy documentation, product listings and your correction responses available on site.

Portland permit search and official resources

Permit records in Oregon sit with the authority that issued them — where Portland Permitting and Development administers the code, it holds the building permit, the inspection history and the certificate of occupancy for work in the City of Portland limits. Many jurisdictions expose permit search through the state ePermitting portal. If you are buying, refinancing or renovating, confirm that past work was permitted rather than assuming it was.

These are the primary sources behind this guide. Codes, fee schedules and portal procedures change — confirm the position for your filing date.
