Seattle Arborist Services & Consulting

Tree removal costs in Washington typically range from $750 to $5,000+, depending on tree size, location, access, and regulatory requirements. In Seattle, pricing is often higher due to strict permitting rules, protected tree classifications, and right-of-way restrictions.

Factors that affect cost include:

Tree height and trunk diameter

Proximity to homes, utilities, or streets

Whether a Seattle tree removal permit is required

Steep slopes, ECAs, or limited access

We provide written, arborist-led evaluations so you understand both the cost and compliance requirements before work begins.

Seattle arborist services typically range from $150–$350 for consultations, with detailed arborist reports, tree risk assessments, or permitting documentation priced separately based on scope.

Costs depend on:

Whether a TRAQ risk assessment is required

Tree protection plans or construction monitoring

SDCI or SDOT documentation needs

Unlike sales-based estimates, our assessments are completed by ISA Certified Arborists who work directly with Seattle regulations.

Yes. We perform formal tree risk assessments using ISA and TRAQ methodologies to determine whether a tree poses a hazard to people, structures, or utilities.

Assessments consider:

Structural defects and decay

Root stability and soil conditions

Lean, load, and exposure factors

Recent site changes or construction impacts

If a tree qualifies for Seattle’s hazard tree exemption, we provide the documentation needed for permitting or removal approval.

Yes. We regularly prepare SDCI-compliant arborist reports, including tree inventories, tree protection plans (TPZs), hazard evaluations, and construction monitoring documentation.

Our reports are used for:

• Tree removal permit applications
• Development and construction projects
• ECA and steep slope compliance
• Dispute resolution and city review

All reports are prepared by ISA Certified Arborists familiar with SMC 25.11.

Yes. We regularly assist Seattle property owners with neighbor tree disputes, including boundary trees, overhanging branches, shared responsibility concerns, and potential hazard conditions.

Our role is to provide neutral, ISA-Certified arborist evaluations that document tree health, structural risk, and site conditions — helping all parties understand what Seattle’s tree code does (and does not) allow.

If you’re dealing with a shared or disputed tree, we recommend reviewing our Boundary Trees & Neighbor Tree Law resources, which explain how Seattle regulations apply to:

• Trees growing on or near property lines
• Overhanging limbs and encroaching roots
• Shared maintenance and removal responsibilities
• When arborist documentation is required

While we don’t provide legal advice, our arborist reports are often used by homeowners, HOAs, and attorneys to resolve disputes calmly, correctly, and with defensible documentation.
