Tree trimming in Spokane, Washington

Pruning rules and permits in Spokane

Spokane splits trees into private and public. Anything wholly on your lot can be pruned without a city permit. A street tree, meaning one in the planting strip or right-of-way, needs a permit from Parks & Recreation – Urban Forestry (509-363-5495) for major pruning, as well as for planting or removal.

Whoever does that public-tree work must be an ISA Certified Arborist with a current Commercial Tree License, so a crew that only holds a general business license should not be cutting the strip tree. The code does allow emergency hazard work on a street tree, provided the city gets notice within one business day; keep photos of what you cut and why.

Light maintenance of your own trees is unregulated, but topping still weakens a tree and invites the kind of breakage snow finds first. If a limb overhangs the boundary, the rules on cutting a neighbor’s branches are in Washington neighbor tree law.

Power lines and utilities in Spokane

This page does not map Spokane’s electric utility yet, so check your bill for your provider and its tree program on the utilities page. As a rule, a homeowner’s crew should not cut near energized lines; that work belongs to line-clearance qualified crews, and the utility often handles the primary lines itself. See trees near power lines.

Ice is the clearance problem to plan around. FEMA rates ice storm Very High for Spokane County, score 97.0, and an ice-coated branch that clears a service drop in October can sag onto it by January. Thinning limbs that hang over the drop to your house is the cut worth making before the season, and a utility can be asked to drop or de-energize the line while it is done.

What trimming costs in Spokane

The modeled range below scales with crew-hours, and for pruning the hours come from height, the number of cuts and whether the crew can lift rather than climb. Tall conifers that need a climber cost more per cut than a maple pruned from a lift.

BLS puts the Spokane-Spokane Valley mean wage for tree trimmers and pruners at $25.94 an hour across 90 jobs. Treat that as an index of local labor cost, not a quote. A street tree adds a permit step, and a certified arborist’s rate rather than a general laborer’s, so expect the upper rows for public-tree work (method).

Modeled estimate, not quotes (method): crew-hours × $210 per crew-hour, rounded to $50.

When to trim in Spokane

Late summer and early fall are the practical window here. July, August and September average under 0.6 inches of rain a month at the Spokane airport station, so ground access is easy, and the cuts are made before the January, December and February peak in storm reports. Dormant-season pruning in late winter also works for deciduous trees once the snow is off.

Avoid heavy pruning just before the first snow; fresh, unbalanced crowns take load poorly. The USDA hardiness zone is 6b, so replacement planting should favor species that handle cold winters; see the tree guides.

What to do next

Decide first whether the tree is yours or the city’s. Private pruning needs nothing from the city; a street tree needs an SMC 12.02.960 permit and a certified arborist with a Commercial Tree License. For a tree with cracks or a heavy lean, a tree risk assessment tells you whether pruning is enough.

Check any contractor through the Washington tree service license lookup before work starts. For removal rules, see tree removal in Spokane, and the county storm data is on the Spokane County page.
