Tree removal permit rules in Multnomah County, OR — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
Private property trees in unincorporated Multnomah County generally do not require permits for removal unless in sensitive land areas (floodplain, habitat, steep slopes, riparian corridor). Tree removal in sensitive areas requires county land use review.
Unlike Portland and Gresham, unincorporated Multnomah County does not require tree removal permits for standard private property trees outside sensitive land areas. Trees in sensitive areas (FEMA 100-year floodplain, steep slope areas, significant habitat areas, riparian corridors, wetlands) require county land use review before removal. Vegetation removal in the flood management area may require a flood hazard permit from the county. Tree removal in conjunction with a land use permit application is reviewed as part of that application. Contact Multnomah County Land Use Planning: 503-988-3043 for sensitive area determinations.
Unauthorized removal: $500 to $10,000 per tree. Replacement planting required. Street tree damage: city restitution costs.
