Marion County Building Inspection handles permits for unincorporated areas and several smaller contract cities, while larger municipalities like Salem and Keizer operate their own independent building departments. Development in the county is subject to extensive rural zoning regulations, and properties within the Willamette River Greenway or designated floodplains require additional specialized review.
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.
