Portland is the largest city in Oregon at about six hundred and thirty-five thousand 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.
Portland consolidated its permitting into a single bureau, Portland Permitting and Development, which now handles building permits, land use, inspections and code enforcement together. On many parcels a land-use review, a historic or design overlay, or an environmental zone clears before or alongside the building permit — treat those as early steps, and pull Cascadia seismic values from the state Design Criteria Hub.
What requires a building permit in Portland?
Oregon runs a single, uniform building code statewide — the Oregon Specialty Codes, administered by the Building Codes Division of the Department of Consumer and Business Services. The code is the same in every jurisdiction; what varies is who administers it and the local land-use approvals layered on top. So in Portland, the technical requirements come from the state code, while Portland Permitting and Development handles the permit, the inspections and the zoning and land-use side.
Permit required
- New residential and commercial construction, additions, alterations and conversions
- Structural and load-bearing work, foundations, decks over the exempt height, and retaining walls above the code threshold
- Finishing basements and attics, garage conversions and any change of use or occupancy
- Electrical work under the Oregon Electrical Specialty Code, including services, circuits, solar and EV charging
- Plumbing under the Oregon Plumbing Specialty Code, and mechanical work under the mechanical code
- Re-roofing above the exempt scope, siding, most window changes, pools, signs and demolition
Typically exempt
- Painting, papering, tiling, carpeting, cabinets and similar finish work
- One-story detached accessory structures below the code floor-area exemption
- Wood, wire-mesh and chain-link fences, exempt by statewide code
- Minor repairs replacing materials in kind, and like-for-like fixture swaps
Because the exemptions are written into the statewide code, they are consistent across Oregon — but an exemption from a building permit is never an exemption from zoning, land use, floodplain rules or an electrical or plumbing permit. Confirm scope with Portland Permitting and Development before work starts rather than after.
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, energy and fire specialty codes. 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.
Two design factors reach nearly every Oregon project. Seismic design under the Cascadia Subduction Zone affects foundations, connections and lateral bracing across much of the state, with site-specific values available through the state Design Criteria Hub. And Oregon’s statewide land-use system means a building permit sits downstream of zoning and land-use compatibility — the land-use question is settled first.
Who handles permitting in Portland?
Portland Permitting and Development handles plan review, permit issuance, inspections, land use and code enforcement inside the city.
| Detail | Information |
|---|---|
| Authority | Portland Permitting and Development (PP&D) |
| Offices | 1900 Southwest Fourth Avenue, Portland 97201 |
| Contact | 503-823-7300 |
| Serves | Work inside the City of Portland limits |
| Code | Oregon Specialty Codes (uniform statewide) |
| Seismic | Cascadia design via the state Design Criteria Hub |
| Overlays | Land use, historic, design and environmental zones |
| Contractor credentials | CCB licence required regardless of value |
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.
Permit types
Residential permits
Residential work spans dense infill, additions, accessory dwelling units and historic-district rehabilitation. Re-roofs, solar and EV chargers need permits, seismic detailing applies broadly, and every contractor must hold a current CCB licence regardless of the size of the job.
How Oregon contractor licensing works
Oregon licensing runs through the Construction Contractors Board (CCB), and its defining feature is that it has no dollar threshold: general contractors, specialty contractors and subcontractors must all hold a current CCB licence to bid or perform construction, regardless of the size or value of the job. This is the opposite of the value-triggered systems in many states.
In Oregon, the licensing question is answered before you look at the project value, not after. Almost any construction for pay requires a CCB licence, so the check is simply whether the contractor holds a current one in the right structure. A narrow exemption lets homeowners do certain work on their own primary residence, but a homeowner who hires out the work is expected to use CCB-licensed contractors.
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 tied to state-licensed installers.
Credentials: CCB plus state trade licensing
Beyond the CCB licence, the trades are licensed by the state: electricians and electrical contractors under the Oregon Electrical Specialty Code, and plumbers under the plumbing code, both administered through the Building Codes Division. So an electrical or plumbing permit is tied to a state-licensed installer, not just a CCB registration. Confirm the CCB licence and the relevant trade licence before filing rather than after the first correction notice.
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.
| Fee component | How it works |
|---|---|
| Building permit | Based on Oregon’s statewide valuation method; the schedule is set locally |
| Plan review | A percentage of the building permit fee, charged at submittal |
| Trade permits | Separate electrical, plumbing and mechanical fees |
| State surcharge | A statewide percentage surcharge added to permit fees |
| Land-use review | Zoning, design or land-use review where the project triggers it |
| Re-inspections and revisions | Additional fees for failed inspections, revisions and expired permits |
Oregon uses statewide valuation methods to calculate building-permit fees, but the schedules and the plan-review percentages are set by each jurisdiction, and a statewide surcharge is added on top. A figure quoted from a neighbouring city or an older packet is not a reliable number, so ask Portland Permitting and Development for the schedule in force on your filing date, and ask separately about plan review, trade permits, the state surcharge and any land-use review fees.

Trade permits and who may pull them
Trade permits are separate from the building permit and are issued to the state-licensed installer. Because Oregon licenses electricians and plumbers at the state level and requires a CCB licence for the contracting business, the credential check has two parts on almost every project: the CCB licence and the relevant trade licence. Confirm both before filing.
Oregon’s trade licensing is a state system, so it is consistent across jurisdictions. An electrical permit is tied to a state-licensed electrical contractor and a plumbing permit to a state-licensed plumbing contractor, wherever the project is. What varies locally is the counter that issues the permit and the inspection schedule, not the licence itself.
- Electrical work is permitted under the Oregon Electrical Specialty Code and tied to a state-licensed electrical contractor.
- Plumbing work is permitted under the plumbing code and tied to a state-licensed plumbing contractor.
- Mechanical work is permitted under the mechanical code; the CCB licence still applies to the business.
Permit required
- Service installations, panel upgrades, new circuits, solar PV and EV chargers
- New plumbing, repipes, water heater change-outs, fixtures, backflow and gas piping
- HVAC installation and change-out, ductwork, venting and commercial kitchen exhaust
- Sprinkler, standpipe and fire alarm work on commercial and multi-family structures
Typically exempt
- Replacing a fixture, switch, receptacle or light with no alteration to wiring or piping
- Clearing a stoppage without replacing or rearranging concealed piping
- Filter, thermostat and routine component service
- Like-for-like appliance repair that does not alter the connection
How to apply for a Portland building permit
Historic, design and environmental zones can gate the building permit.
Land use frequently clears ahead of the building permit.
Cascadia design applies broadly in Portland.
Oregon requires it regardless of project value.
Trade permits are tied to state-licensed installers.
Confirm the sets and forms review needs.
Review, corrections and what actually causes delay
In Oregon, delay tends to come from the land-use and site side rather than the code text, since the code itself is uniform statewide. The common causes are an unresolved zoning or land-use question, a seismic or site-design value that was not pulled from the Design Criteria Hub, a missing CCB or trade licence, or a submittal that did not match what Portland Permitting and Development needs. Settle the land-use question first, then file the building permit.
Approvals do not stay live indefinitely. An Oregon building permit carries a validity period and can expire if work does not start or stalls between inspections. On phased work or a project waiting on financing, confirm the expiry before it passes — reviving a lapsed permit is more work than keeping one active.
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 schedule inspections online or by interactive phone system, often through the state ePermitting platform; 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.
The code is statewide, but the counter is local. Fees, submittal lists, review turnaround and land-use requirements are set by the administering jurisdiction; the technical code is not. Confirm current requirements, fees and review turnaround for your filing date.
These are the primary sources behind this guide. Codes, fee schedules and portal procedures change — confirm the position for your filing date.
