Pruning rules and permits in Kent
Kent’s street-tree chapter is explicit. KCC 6.10.060(B) prohibits planting, removing, trimming or cutting any tree in the strip between the property line and the curb unless the Parks Director has issued a written permit, and a violation is a misdemeanor. That covers the planting strip in front of most houses, even if you water and rake under it.
On private land the picture is lighter for pruning. The King County 2024 summary cited for Kent sets a significant tree at 6 inches DBH and treats removal on single-family lots as otherwise unlimited outside critical areas, under KCC 15.08.240. That text was not retrieved directly, so treat it as partly verified.
Get the Parks permit in writing before a crew touches a curbside tree.

Power lines and utilities in Kent
Puget Sound Energy serves Kent. PSE trims near overhead primary lines in its right-of-way, but it does not publish a clearance distance for trimming; the only figure it gives is 10 ft, cited as the distance at which a line is an electrocution risk. For anything more specific about your line, call the number on your bill.
PSE does not trim service lines, the wire from the pole to your house. Instead it performs a safety disconnection so you or a private arborist can trim, and any cut close to an energized line belongs to a qualified line-clearance crew. A planting-strip tree under a line can involve both PSE and the Parks Director, so sort out who cuts before anyone climbs. Outage line: 1-888-225-5773; a downed line is 911. Background: trees near power lines.

What trimming costs in Kent
Pruning is priced by crew-hours in the modeled range below. A curbside tree can add a permit step and traffic or sidewalk setup, which nudges a small job upward; a backyard tree with clear access sits lower.
The labor input is the Seattle-Tacoma-Bellevue area, where BLS counts 310 tree trimmers and pruners at a $33.85 mean hourly wage. That is a wage index, not a price (methodology).
| Tree size | Crew-hours | Washington modeled range |
|---|---|---|
| Small ornamental | 1–3 | $200–$650 |
| Medium tree | 3–8 | $650–$1,700 |
| Large or mature tree | 8–16 | $1,700–$3,350 |
Modeled estimate, not quotes (method): crew-hours × $210 per crew-hour, rounded to $50.

When to trim in Kent
Weight, not wind, breaks most limbs in King County. Heavy snow accounts for 68 of 133 NOAA reports since 2016 and ice storms for 11, with 84% arriving November through February. Thinning dense crowns before that window reduces the load a branch carries.
Kent is in USDA zone 8b. Structural pruning on deciduous trees fits the dormant months, and a street tree needs the permit lead time added to your schedule.

What to do next
Find your property line first: if the tree is between it and the curb, request the Parks Director permit before you book. For trees fully on your lot, check for critical areas under KCC 15.08.240.
Verify the contractor with the Washington license lookup. The Kent tree removal page covers taking a tree out, and King County has the storm record.
