Oregon Tree Permit Requirements by County: Complete 2025 Guide
Oregon tree permit requirements vary by city, not county. Portland requires permits for trees over 6-inch DBH ($35-$150 fee). Eugene requires permits for trees over 5-inch DBH. Salem, Corvallis, Lake Oswego, Beaverton, and Bend all have tree ordinances. Rural properties under county jurisdiction generally have fewer restrictions. Always check with your city planning department before removal.
Oregon Tree Permit Guide: City by City

- Fees: $35-$150 depending on tree size and zone
- Processing time: 2-4 weeks for standard applications
