Tree removal permits in Tukwila

Ordinance 2569 sets the scale: a significant tree is 6 inches DBH or larger, and an exceptional tree is over 18 inches. On a single-family lot outside critical areas, TMC 18.54 lets you remove, in any 36-month period and without replacement, one tree 18 inches or larger, or two trees between 8 and 18 inches, or four trees between 6 and 8 inches. Past that allowance, replacement follows the city checklist by size: 1 tree for 6 to 8 inches, 1.5 for 8 to 15, and 2 for 15 and up.

Shoreline and critical areas work differently. Under TMC 18.44 and 18.45.158.C.4 only hazardous trees come out there, and a hazard call needs a TRAQ-qualified arborist. An unpermitted removal can be fined $1,000 per tree. Whatever the size, contact the city before cutting any tree of 6 inches or more, through the Community Development Permit Center or the Urban Environmentalist at 206-839-6483. Street-tree rules were not verified. See the Washington permit guide for comparisons.

Storm records for King County (covers Tukwila)

One day defines King County’s recent storm record: the east wind of November 19, 2024. NOAA logged 7 high-wind reports for the county that day, and the regional toll it describes, homes and cars hit, long outages and 2 deaths from falling trees, came from a wind direction Puget Sound trees rarely brace against.

The broader file is snowier than that day suggests. Of 133 reports, 68 are heavy snow, 23 high wind, 13 winter weather and 11 ice storm, and 84 percent fall between November and February, peaking in February, December and January. King ranks 16th of Washington’s 39 counties, reports have fallen to 32 in the latest three years from 54, and FEMA’s National Risk Index (December 2025) rates ice storm and winter weather Relatively High at 91.1 and 94.7.

On November 19, 2024, a low deepened quickly over the waters off Western Washington and drove strong easterly winds into the Puget Sound region. Trees here grow braced for southwesterly winter storms, so the unusual direction plus the force brought them down widely, damaging homes and vehicles, cutting power for long stretches and killing 2 people. NOAA’s 7 King County reports cover the Seattle area, the Bellevue area and the East Puget Sound lowlands. For Tukwila, judge a tree’s lean and root plate from every side, not just the southwest.

Growing conditions in Tukwila

Tukwila sits in USDA hardiness zone 9a, among the milder zones in the region. Replacement trees under the TMC 18.54.080 ratios should be picked for two loads the county record shows: wet snow and ice through winter, and the occasional east wind like November 2024. Keep fast growers well away from service lines, where Seattle City Light’s targets leave only 3 to 5 feet.

Labor index for Tukwila

BLS puts tree trimmers and pruners in the Seattle-Tacoma-Bellevue area at a $33.85 mean and $32.75 median hourly wage, about 310 workers. That is a wage, not a price. A shoreline or critical-area removal adds an arborist’s hazard report, and going past the 36-month allowance adds 1 to 2 replacement trees per removal; the modeled ranges on the service pages start from crew-hours and stack those on top.

Tree services in Tukwila

The service pages pair Tukwila’s rules with Washington’s modeled ranges. Removal covers the 36-month allowance and replacement ratios; trimming covers Seattle City Light’s clearance distances; stump grinding starts with 811; and emergency service covers winter snow and the rare east wind.

What to do next

Count what you have removed in the last 36 months, measure the tree at breast height, and call the Urban Environmentalist at 206-839-6483 before cutting anything 6 inches or larger. In a shoreline or critical area, a TRAQ-qualified risk assessment comes first, since only hazard trees qualify there. Check the contractor in the Washington license lookup before paying a deposit; at $1,000 per tree, a skipped permit can cost more than the job.
