City of Seattle Tree Removal Permit: Costs, Rules, and How to Stay Compliant (2026)

January 15, 2026

TLDR: If you want to remove a tree six inches or larger in diameter on your Seattle property, you must obtain a tree removal permit from the Seattle Department of Construction & Inspections (SDCI), with fees ranging from $0 to $2,800 depending on circumstances, and failure to comply can result in fines up to $32,500 per tree.

Key Takeaways

  1. Permit requirements apply to most significant trees: Any tree measuring six inches or more in diameter at standard height (4.5 feet above ground) requires a permit before removal on Seattle residential properties.

  2. Costs vary significantly based on tree classification: Permit fees range from free for hazardous trees to $2,800 for exceptional trees, with additional costs for professional arborist assessments and actual removal services.

  3. Environmentally critical areas have stricter rules: Properties located in steep slopes, wetlands, riparian corridors, or other ECAs face heightened scrutiny and may require additional environmental review.

  4. Professional assistance streamlines the process: Licensed landscaping and tree service companies can handle permit applications, arborist reports, and compliant removal, saving homeowners considerable time and potential legal exposure.

Seattle actively protects its urban canopy: The city's regulations aim to maintain approximately 28 percent tree canopy coverage, and enforcement actions have increased substantially in recent years.

Understanding Seattle's Tree Protection Regulations

Seattle takes urban forestry seriously. According to the Seattle Department of Construction & Inspections, the city's tree canopy currently covers roughly 28 percent of total land area, a figure that environmental scientists and urban planners consider essential for air quality, stormwater management, and climate resilience.

The U.S. Forest Service reports that urban trees provide approximately $18.3 billion in annual benefits to American cities through air pollution removal, carbon sequestration, and energy savings. Seattle's commitment to protecting this resource translates directly into the regulatory framework homeowners must navigate when considering tree removal.

Industry Insight: According to the National Association of Landscape Professionals, the landscaping and tree care industry generates approximately $176 billion annually in the United States, with residential tree services representing one of the fastest-growing segments.


How Do I Apply for a City of Seattle Tree Removal Permit for My Property?


Applying for a tree removal permit in Seattle requires methodical preparation and attention to regulatory details. The process involves several distinct steps, each with specific requirements that can delay approval if not handled correctly.

Step 1: Determine If Your Tree Requires a Permit

Not every tree requires a permit for removal. Seattle regulations establish clear thresholds:

   

Tree Characteristic

Permit Required?

Diameter under 6 inches at standard height

No

Diameter 6 inches or more (residential zones)

Yes

Exceptional tree (any diameter threshold met)

Yes, with additional review

Tree in Environmentally Critical Area

Yes, with environmental review

Hazardous tree posing immediate danger

Expedited permit process

Tree on commercial property

Development permit required


Step 2: Gather Required Documentation

Before submitting your application, compile the following materials:

A completed Tree Removal Application Form available through the Seattle Services Portal or SDCI offices.

A site plan showing your property boundaries, the location of all significant trees, structures, and the specific tree or trees you wish to remove.

Photographs documenting the tree's condition, particularly if you're claiming hazardous status or disease.

An arborist report from a qualified professional if you're removing an exceptional tree or claiming the tree poses a safety hazard.

Step 3: Submit Your Application

Applications are submitted through the Seattle Services Portal online or in person at SDCI's downtown office. Processing times vary based on application complexity.

Highlight: The average permit processing time for straightforward residential tree removal is 4 to 8 weeks. Exceptional tree removals or properties in environmentally critical areas may require 8 to 12 weeks or longer.

Step 4: Await Review and Respond to Requests

SDCI staff will review your application and may request additional information. Common requests include more detailed arborist assessments, revised site plans, or documentation supporting your stated reason for removal.

Step 5: Receive Your Permit and Schedule Removal

Once approved, you'll receive your permit with specific conditions. These often include replacement tree requirements, protection measures for adjacent trees, and time limitations for completing the work.

What Is the Cost Involved in Getting a City of Seattle Tree Removal Permit and Removal Service?


Understanding the full cost picture requires separating permit fees from actual removal services, as both represent significant but distinct expenses.

Permit Fee Structure (2026)

Seattle's permit fees reflect the city's commitment to canopy preservation, with higher fees for removing larger or more valuable trees:

 

Permit Type

Fee Range

Hazardous tree removal

$0 (fee waived)

Standard tree removal (6-12 inch diameter)

$86 - $172

Which Services Assist with the Application Process for a City of Seattle Tree Removal Permit?


Navigating Seattle's tree removal regulations doesn't have to be a solo endeavor. Several types of professionals can assist at various stages of the process.

Certified Arborists

International Society of Arboriculture (ISA) certified arborists provide the technical assessments that support permit applications. These professionals evaluate tree health, structural integrity, and potential hazards. Their reports carry significant weight with SDCI reviewers, particularly when removal justification involves safety concerns or disease.

According to the ISA, there are approximately 3,400 certified arborists currently practicing in Washington State, though not all specialize in permit-related work.

Full-Service Tree Companies

The most efficient approach for most homeowners involves engaging a full-service tree company that handles both permitting and removal. These companies typically offer:

  • Initial property assessment and tree inventory
  • Permit application preparation and submission
  • Communication with SDCI throughout the review process
  • Compliant tree removal following permit approval
  • Replacement tree planting when required
  • Documentation for your records

Environmental Consultants

Properties in environmentally critical areas may require environmental assessments beyond standard arborist reports. Environmental consultants specialize in evaluating impacts on wetlands, steep slopes, wildlife corridors, and other sensitive features.

Permit Expediting Services

For complex projects or time-sensitive situations, permit expediting services can accelerate the review process through proper channels. These services understand SDCI's workflows and can identify potential issues before they cause delays.

Professional Recommendation: When selecting a tree service provider, verify they hold both a Washington State contractor's license and appropriate liability insurance. Ask specifically about their experience with Seattle's permit requirements and request references from similar projects.

Matt's Tree Service provides comprehensive permit assistance throughout Seattle, Sammamish, and Issaquah, handling every step from initial consultation through project completion.

What Documents Are Required for Obtaining a City of Seattle Tree Removal Permit?


Successful permit applications depend on thorough documentation. Missing or inadequate materials represent the most common cause of delays and denials.

Core Required Documents

Tree Removal Application Form The official SDCI application form requires property owner information, tree location details, species identification if known, diameter measurements, and stated reason for removal. Accurate completion is essential since errors can delay processing.

Site Plan Your site plan must show:

  • Property boundaries with accurate dimensions
  • Location of all trees six inches or larger in diameter
  • Identification of the specific tree or trees proposed for removal
  • Structures, driveways, and other significant features
  • North arrow and scale

Professional site plans prepared by licensed surveyors or landscape architects strengthen applications, though hand-drawn plans meeting these requirements may be accepted for straightforward residential projects.

Photographs Document the tree's condition with clear photographs showing:

  • Full tree from multiple angles
  • Trunk base and root flare area
  • Canopy condition
  • Any visible damage, disease, or structural issues
  • Proximity to structures or other features relevant to removal justification

Conditional Required Documents

Arborist Report Required for exceptional tree removal and strongly recommended for any removal claiming hazardous conditions. The report must come from an ISA-certified arborist and address:

  • Tree species and age estimate
  • Overall health assessment
  • Structural evaluation
  • Risk assessment if claiming hazardous status
  • Recommendations regarding removal necessity

Environmental Review Materials Properties in environmentally critical areas require additional documentation:

  • Critical areas study
  • Mitigation plan
  • Habitat assessment if applicable
  • Stormwater impact analysis

Replacement Tree Plan When replacement trees are required as a permit condition, provide:

  • Species selection with suitability justification
  • Proposed planting locations
  • Maintenance commitment timeline

Document Checklist Highlight

Before submitting your application, verify you have:

  • [ ] Completed application form with accurate measurements
  • [ ] Legible site plan with all required elements
  • [ ] Clear photographs documenting tree condition
  • [ ] Arborist report (if required or beneficial)
  • [ ] Proof of property ownership or authorization
  • [ ] Payment for applicable fees

Understanding Seattle's Tree Categories and Protection Levels

Seattle's regulations establish distinct protection levels based on tree characteristics. Understanding these categories helps homeowners anticipate permit complexity and cost.

Significant Trees

Any tree measuring six inches or more in diameter at standard height (4.5 feet above ground) qualifies as a significant tree under Seattle code. These trees require permits for removal on most residential properties.

Exceptional Trees

Exceptional trees receive the highest protection level. A tree qualifies as exceptional if it meets species-specific diameter thresholds established by SDCI, typically ranging from 24 to 30 inches depending on species. These thresholds recognize the irreplaceable ecological and aesthetic value of mature specimens.

 

Tree Type

Exceptional Diameter Threshold

Most conifers

30 inches

Most deciduous

24 inches

Heritage varieties

Case-by-case determination

Trees in groves

Reduced thresholds may apply

Exceptional tree removal requires documented justification meeting specific criteria and SDCI director approval. Replacement requirements are more stringent, and penalties for unauthorized removal are substantially higher.

Trees in Environmentally Critical Areas

Environmentally critical areas (ECAs) include:

  • Steep slopes (40% grade or greater)
  • Wetlands and wetland buffers
  • Riparian corridors along streams and shorelines
  • Wildlife habitat areas
  • Geologically hazardous areas

Trees in ECAs face additional scrutiny because they often provide essential erosion control, habitat, and water quality functions. Removal applications require environmental review demonstrating that impacts are minimized and mitigated.

Street Trees

Trees located between sidewalks and streets fall under Seattle Department of Transportation jurisdiction rather than SDCI. Different permit processes and fees apply, and homeowners generally cannot remove street trees without specific approval from SDOT's Urban Forestry division.


How Zoning Affects Tree Removal Rules in Seattle

Your property's zoning classification directly impacts tree removal regulations. Seattle's approach varies between residential, commercial, and industrial zones.

Single-Family Residential Zones

Most Seattle homeowners fall within single-family zones where the standard permit framework applies. You may remove up to three significant trees per year through the standard permit process, with exceptional trees requiring individual review regardless of this limit.

Multifamily Residential Zones

Multifamily properties face stricter requirements, with removal typically requiring demonstration that the tree prevents reasonable development or poses documented safety risks. Replacement ratios are often higher than single-family requirements.

Commercial and Industrial Zones

Development permits in commercial zones incorporate tree requirements into the broader project review. Tree removal is evaluated as part of overall site development rather than through standalone permits.

Shoreline Zones

Properties within shoreline jurisdiction face overlapping regulations from both SDCI and the Shoreline Management Act. Buffer requirements often restrict removal regardless of tree condition.

Zoning Verification: Confirm your property's zoning classification before beginning the permit process. SDCI's online mapping tools provide this information, or a professional tree service can determine applicable regulations during your initial consultation.

Emergency Tree Removal: What to Do When a Tree Becomes Hazardous

Severe weather events and sudden tree failures don't wait for permits. Seattle's regulations accommodate genuine emergencies while preventing misuse of emergency provisions.

Imminent Hazard Situations

When a tree poses immediate danger to persons or property, you may take necessary action to eliminate the hazard. However, this doesn't mean permits are unnecessary. Rather, emergency removal triggers an expedited permit process.

Qualifying emergencies include:

  • Trees actively failing or partially fallen
  • Trees with visible structural damage following storms
  • Trees impacting utility lines or blocking emergency access
  • Root plate lifting indicating imminent failure

Emergency Process Steps

  1. Document the emergency: Before any work begins, photograph the hazardous condition from multiple angles with timestamps.

  2. Contact utilities if applicable: If power lines are involved, contact Seattle City Light before any tree work.

  3. Perform only necessary work: Emergency authorization covers only the immediate hazard. Remaining portions of the tree may require standard permits for complete removal.

  4. File emergency permit within 7 days: Submit your permit application with emergency documentation within one week of the initial work.

  5. Provide arborist verification: An ISA-certified arborist must verify that emergency conditions existed, typically through a post-incident report.

Emergency Contact Information

For after-hours tree emergencies affecting public safety, contact Seattle's emergency services. For private property emergencies,Matt's Tree Service Emergency Response provides 24/7 availability for urgent situations throughout the Seattle area.


Penalties for Illegal Tree Removal in Seattle

Seattle actively enforces its tree protection regulations, and penalties have increased substantially in recent years. Understanding potential consequences emphasizes the importance of proper permitting.

Exceptional Diameter Threshold

Most conifers

30 inches

Most deciduous

24 inches

Heritage varieties

Additional Consequences

Beyond monetary penalties, violators may face:

  • Replacement requirements: Replanting at ratios up to 3:1 for exceptional trees
  • Development restrictions: Properties with violation history face increased scrutiny for future permits
  • Liens: Unpaid penalties can result in property liens
  • Civil liability: Neighboring property owners may pursue additional damages through civil action

Enforcement Trends

SDCI has increased enforcement resources in response to documented violations. According to city records, enforcement actions have risen approximately 40 percent over the past five years, with particular attention to exceptional trees and ECA violations.

Compliance is Cost-Effective: Even complex exceptional tree permits with full professional assistance cost substantially less than minimum violation penalties. Proper permitting protects both your property and your finances.

Tree Trimming vs. Tree Removal: Understanding the Distinction

Homeowners sometimes confuse trimming and removal requirements. Understanding the difference prevents unintentional violations.

Trimming Without Permits

Routine pruning and trimming generally don't require permits when performed according to professional standards. Acceptable unpermitted work includes:

  • Removal of dead, dying, or diseased branches
  • Crown cleaning and thinning following ISA guidelines
  • Clearance pruning for structures and utilities
  • Hazard reduction that doesn't significantly alter tree structure

When Trimming Becomes Removal

Trimming crosses into removal territory when it:

  • Removes more than 25 percent of the tree's crown in a single year
  • Tops the tree or removes the central leader
  • Damages the tree to the point where survival is unlikely
  • Constitutes topping or lion-tailing (improper practices)

Such aggressive trimming may be treated as unpermitted removal, triggering the same penalties.

For professional trimming services that maintain tree health while respecting Seattle's regulations,Matt's Tree Service provides ISA-certified arborist oversight on every project.


Appealing a Denied Tree Removal Permit

Permit denials aren't necessarily final. Seattle provides an appeal process for homeowners who believe their applications were wrongly denied.

Grounds for Appeal

Valid appeal grounds include:

  • Factual errors in SDCI's review
  • Failure to consider submitted evidence
  • Misapplication of regulations
  • New information relevant to the decision

Appeal Timeline

Appeals must be filed within 14 days of permit denial. Missing this deadline typically forfeits appeal rights.

Appeal Process

  1. File written appeal with the SDCI Director
  2. Provide specific grounds and supporting documentation
  3. Attend informal conference if offered
  4. If informal resolution fails, request hearing before the Hearing Examiner
  5. Hearing Examiner decision is binding unless appealed to Superior Court

Improving Appeal Success

Working with experienced professionals increases appeal success. Certified arborists can provide additional technical documentation, while tree service companies familiar with SDCI's review criteria can help identify where initial applications fell short.
