Zoning Plan Check and Sign Permit (Unincorporated Multnomah County)

For property in unincorporated Multnomah County, county Land Use Planning reviews building plans for zoning before a building permit is issued. The county's Submitting a Building Plan for Zoning Review page states that any required land use permits must be approved first, that plans are submitted through the county customer portal under the 'Zoning Plan Review' option, and that an application counts as received only once its fees are paid. The fee figures are those on the county's Land Use Planning Fees page, headed 'Multnomah County Land Use fee schedule effective July 1, 2026', which match the FY 2027 County Fee Schedule. Inside the Portland Urban Services Boundary, City of Portland-administered land use services fees apply instead: Resolution 2026-043, adopted 18 June 2026 and effective 10 July 2026, sets those fees for the unincorporated areas within that boundary. Property inside an incorporated city follows that city's zoning and sign rules.
