Oregon City, Oregon Building Permit Guide

Inside Oregon City, the Building Division of Community Development issues building, electrical, plumbing, mechanical, fire system, solar and demolition permits. Since January 1, 2025 applications go through the City’s Citizen Self Service (CSS) portal or by email to permits@orcity.org, not the state’s ePermitting site. Fees follow the City’s January 2025 schedule: a building permit fee from the project valuation, plus plan review at 65% of that fee, paid before review begins.

The office is at 695 Warner Parrott Road and takes walk-in visitors Monday to Thursday from 9 a.m. to 4 p.m., with no payments after 3:30 p.m.; on Fridays it works by phone, email or appointment only. Oregon City, the seat of Clackamas County, had 38,175 residents in the Census estimate for 2025.

Land outside the city limits is under Clackamas County, which also runs the septic program for lots that are not on a sewer.

What requires a building permit in Oregon City?

The Building Division’s forms and fee schedule show which work it permits: new houses and commercial buildings, additions and remodels, decks and patio covers (it publishes guides for both), re-roofs, demolition, fire alarm and sprinkler work, solar panels, moved buildings, signs and the electrical, plumbing and mechanical work inside them. A few of its rules are more specific than people expect.

What the city decides and what the state holds

Oregon City applies the state’s specialty codes and their exemptions. The City Commission sets the fee schedule by resolution, and the City sets its own portal, payment and submittal rules, the fire access review requirement under Resolution 22-01, the floodplain rules in chapter 17.42 of the municipal code, and the work hours for construction in residential neighborhoods.

Oregon’s building code and its exemptions are the same in Oregon City 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

Oregon City building department: who handles permitting

The Building Division reviews plans, issues building and trade permits and inspects, and it also reviews construction in the special flood hazard area. Planning approves land use, and the residential checklist has zoning items such as flood plain, historic district and seismic soils designations confirmed during plan review. Development Services and Engineering handle erosion control, site utilities and right-of-way permits. Clackamas Fire does a separate fire access and water supply review and joins the City on many inspections, mostly finals.

Permit types

Residential permits

The residential page holds the building permit, new single-family home, manufactured dwelling, demolition and trade applications, along with an application checklist, a property owner statement for owners doing their own work, a subcontractor list, a septic decommissioning certificate, a moisture content form, a special inspection form, a permit extension request and guides for decks and patio covers. A new single-family dwelling has its own submittal package. The residential checklist starts with a completed planning application form and asks whether the lot has a flood plain, solar balance point, seismic soils designation or historic district, and whether a septic permit or authorization is needed for a remodel.

Commercial permits

Commercial applications go through CSS, and large files can be sent through an upload link requested from permits@orcity.org. The commercial page adds an ADA accessibility compliance report for tenant improvements, a deferred submittal agreement, fire alarm and sprinkler affidavits, mechanical, electrical and plumbing plan review requirements, a rooftop mechanical unit checklist, a site utilities application and a request to energize electrical installations. Large projects must split their submittal by discipline, with an application and plan review fee for each, and fire and life safety review is 65% of the building permit fee.

For tenant improvements and new commercial builds, Alliance handles commercial permit applications through issuance. More on this: commercial building permits explained.

What comes before the building permit

Land use must be approved by Planning before the building application is submitted, and any land use file number goes on the application. Under City Resolution 22-01, in force since July 1, 2022, newly proposed residential properties, new commercial properties and significant commercial additions or changes of use need a separate fire access and water supply review from Clackamas Fire District, approved and sent to permits@orcity.org before the permit is issued. Demolition needs a DEQ asbestos abatement report before the permit is issued, and wells, sewer lines and septic tanks must be capped, removed or filled and inspected by the City. Clearing over 1,000 sq ft or moving more than 10 cubic yards of material takes an erosion control permit from Public Works, and work in the street needs an Engineering permit.

Oregon City permit costs and fees

The fee schedule in force is the Building Division Fee Schedule dated January 1, 2025, set under the City Commission’s fee resolution authority (Resolution 16-01). New construction is valued with the state-mandated valuation table; for remodels and repairs the applicant states the value, including all labor and materials but not land. The schedule lists the state surcharge as “as determined by State of Oregon”, and the City’s permit policy describes it as currently 12%.

Worked example. A remodel valued at $80,000 sits in the $50,001 to $100,000 band: $736.54 for the first $50,000 plus 30 × $6.95 ($208.50) gives a building permit fee of $945.04. Plan review at 65% is $614.28, paid before review starts, and a 12% state surcharge on the permit fee is $113.40.

Payment is by Visa, Mastercard or check; the City caps card payments at $500 per project per department, so larger fees go by check. Final fees are invoiced only after every department approves the plans, and the permit, receipt and stamped plans then arrive by email.

Trade permits and who may pull them

Oregon City issues its own electrical, plumbing and mechanical permits, on applications revised in January 2025 and filed through CSS. Electrical permits include a set number of inspections (four for a single-family or multifamily dwelling, three for renewable energy, two for most others), and extra visits cost $105 each. Residential mechanical permits start at a $105 minimum, and a 200-amp service is $199.

The City will not accept an application until it has checked the contractor’s licenses.

How to apply for an Oregon City building permit

Review, corrections and what causes delay

The City counts the submittal date from the day the application is complete, meaning every required document has been received and checked. A plans examiner contacts the applicant when more information is needed; red ink is reserved for City corrections, and deferred submittals and revisions need the City’s transmittal sheet with the permit number. Large projects stall if mechanical, electrical or plumbing drawings arrive without their own application and paid review fee. A plan review period can be extended for 90 days at a time, no more than twice, and no extension is considered more than a year after the application.

Inspections in Oregon City

Inspections can be requested at any hour in CSS, by phone on 503-496-1551 or by fax to 503-722-3880. A request made before midnight is normally inspected on the date requested; later requests go to the next business day. Inspectors work 8:30 a.m. to 3:30 p.m., Monday to Friday. The phone line is touch-tone only and needs the permit number, the date and the three-digit inspection code; lock-box details or a call-back number have to go in online. Clackamas Fire marshals, who join many final inspections, work only Monday to Thursday, so those inspections are limited.

In the special flood hazard area the City needs an elevation certificate marked “construction drawings” before the foundation inspection and a finished-construction certificate before final inspection or occupancy. Oregon City participates in the National Flood Insurance Program; its current FEMA map, per the Community Status Book, took effect on June 17, 2008. A permit expires after 180 days with no recorded activity, but activity on any related permit for the same project resets the clock for all of them. An extension requested before expiry is free, one within 30 days after costs $101, and reinstating an expired permit costs a share of the original fee set by the Building Official for the work left (2025 fee schedule); the City’s 2024 policy sheet still shows half the fee up to $505, or the full fee up to $1,010 after 180 days, and a new submittal once a new code has been adopted. Construction in residential neighborhoods is limited to 7 a.m. to 6 p.m. on weekdays and 9 a.m. to 6 p.m. at weekends and on legal holidays.

Oregon City building permit FAQ

Can I apply for an Oregon City permit on the state ePermitting site?

No. Since January 1, 2025 Oregon City applications go through the City’s Citizen Self Service portal, or by email to permits@orcity.org.

How much is a building permit in Oregon City?

Under the January 2025 schedule the minimum is $105 and an $80,000 remodel pays $945.04, plus $614.28 plan review and the state surcharge. Fee changes go to a public hearing on December 2, 2026.

Do I need a permit to re-roof my house?

The City’s fee schedule ties the $185 residential re-roof permit to replacing 30% or more of the roof sheathing. The 2026 state residential code, mandatory since October 1, 2026, exempts reroofing that adds 4 psf of dead load or less, including damaged sheathing, except on townhouses, attached stacked two-family dwellings, photovoltaic roof coverings and roofs that had to meet the R327 wildfire standards under local adoption.

Why does my new house need Clackamas Fire approval?

City Resolution 22-01 requires a separate fire access and water supply review for new residential properties, and the approval must reach the Building Division before the permit is issued.

When are inspections done?

Monday to Friday, 8:30 a.m. to 3:30 p.m. Requests made before midnight are normally inspected on the date requested; finals that need a fire marshal happen Monday to Thursday.

Can I pay by credit card?

Yes, Visa or Mastercard, up to $500 per project per department; larger amounts go by check payable to the City of Oregon City.
