How to Apply in Seattle
- Confirm the tree requires a permit — measure DBH at 4.5 feet above ground. Contact Seattle's Development Services to confirm species and size thresholds for your address.
- Prepare your documentation — property address, site sketch showing tree location, photos of the full tree and trunk, species identification, and trunk diameter measurement.
- Submit the application — most Seattle applications are available online through the city's permit portal, or in person at the Development Services office.
- Pay the fee and wait for review — standard review takes 5–15 business days. Large or heritage trees may take longer. Do not begin any removal until written approval is in hand.
- Complete removal and any mitigation — fulfill any replacement planting or mitigation fee requirements within the timeframe specified on your permit.
