What requires a building permit in Polk County?

Before applying for a building or manufactured structure permit, the county asks you to contact the Planning Division to confirm the use is allowed in the zone, the setbacks, and whether a land use application is needed first. Non-structural floodplain work, such as filling, grading, paving or excavation in an identified floodplain, needs a land-use review first; the rules are in Chapter 178 of the county Zoning Ordinance. A new address application goes in with the permit for new dwellings or commercial structures on vacant land, hardship or replacement dwellings, or a new access.

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