Quick answer

Do You Need a Site Plan for a Permit in Oregon?

Yes, most building permits in Oregon need a site plan: a scaled drawing of the lot, existing buildings and the new work, with distances to the property lines. In Oregon, cities issue building permits inside their limits and the county issues them in unincorporated areas. Your address decides which office reviews your plans. We check that office’s requirements before quoting.
