CODES & LOCAL AUTHORITY
FIPS 41051
Article I · County Baseline

The county inherits from the state. And adds local rules.

The county and its cities generally adopt the Oregon Structural Specialty Code based on the 2021 International Building Code.

Multnomah County only manages building and land use permits for unincorporated areas, while incorporated cities like Portland, Gresham, and Troutdale manage their own permitting. Unincorporated areas are subject to significant geographic overlays including the Columbia River Gorge National Scenic Area, Willamette River Greenway, and various hillside and flood hazard regulations.

Properties within the Columbia River Gorge National Scenic Area are subject to strict development standards and design reviews that are significantly more restrictive than standard county zoning.

How this fits with the state

The state authority here is Oregon Construction Contractors Board. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.

Frequently Asked

Questions contractors ask before filing.

Q01Do I need a state license to work in Multnomah County?+
Usually yes — the baseline is the state license through Oregon Construction Contractors Board. Multnomah County and its cities may add local registration before you pull a permit.Source · Oregon Construction Contractors Board
Q02Does the county or the city issue the permit?+
It depends on where the work is. Unincorporated areas usually route through the county (City-by-city; Portland and other incorporated cities run independent permit portals for their jurisdictions.). Work inside an incorporated city normally files with that city's department.Source · City-by-city; Portland and other incorporated cities run independent permit portals for their jurisdictions.
Q03What changes between county and state?+
The county adds the actual permit office, local zoning overlays, plan-review timelines, inspections, and local fees. The state license defines who can contract; the county defines how the job gets filed.Source · County and municipal departments
