Understanding Permits, Costs, and City Tree Rules
Seattle is renowned for its lush greenery and natural beauty. The city's thriving urban forest, comprising various tree species, contributes to its unique charm and ecological balance. It plays a pivotal role in reducing the city’s temperature, preventing erosion, and improving air quality. The local authorities, including theSeattle Department of Construction and Inspections (SDCI), have implemented regulations to ensure this precious resource's preservation and management.
Can You Chop Down a Tree in Seattle? (Quick Answer)
Short answer: Sometimes—but not without checking Seattle’s tree regulations first.
In Seattle, tree removal is regulated to protect the city’s urban forest. Whether you’re allowed to remove a tree depends on
its size, location, species, and condition, as well as whether it’s considered a
street tree, significant tree, or located within an environmentally critical area (ECA). In many cases, a
tree removal permit is required before any work can begin.
There are limited exceptions—such as
emergency or hazardous tree removals—but even those situations typically require
documentation by a certified arborist and follow-up reporting to the city. Removing a tree without approval can result in
fines, replacement requirements, and project delays.
If you’re unsure whether your tree can be removed, the safest first step is to review Seattle’s permitting rules or have a
qualified arborist evaluate the tree and site conditions before taking action.

When Is Tree Removal Allowed in Seattle?
Tree removal is allowed in Seattle under specific circumstances, but requirements can vary based on safety concerns,
tree condition, location, and site context. Below are the most common scenarios where removal may be permitted.
Emergency & Hazardous Tree Removal
Removal is generally allowed when a tree poses an immediate risk to life or property
—for example,
active failure, major structural damage, advanced decay, root instability, or severe storm impacts.
- Often requires documentation by a qualified arborist
- Removal should be limited to what’s necessary to address the hazard
- Post-removal documentation or notification may still be required
Emergency removals aren’t blanket exemptions—especially for street trees, significant trees,
or trees within Environmentally Critical Areas (ECAs).
Storm-Damaged & Failed Trees
Trees that have failed, partially failed, or been severely damaged
during storms are often eligible for
removal when they create unsafe conditions or obstruct access.
- Uprooted or suddenly leaning trees
- Broken tops or major split limbs
- Compromised roots in saturated soils after heavy rainfall
Depending on classification and location, Seattle may still require photos, an arborist statement, or follow-up review.
Interference With Structures or Utilities
Removal may be allowed when a tree is causing documented damage
or unavoidable interference with structures,
infrastructure, or service lines (roofs, foundations, retaining walls, and similar).
- Proximity alone usually isn’t enough to justify removal
- Pruning or mitigation may be required before removal is approved
- Utility corridors and street trees
can involve additional oversight
In many cases, clearance pruning
is permitted even when full removal is not.
Construction & Development
Removal related to construction, grading, or redevelopment typically requires prior approval
and is more
closely regulated in Seattle.
- Trees may be evaluated during site or land-use review
- Replacement planting or mitigation may be required
- ECAs, shorelines, and steep slopes often have stricter standards
This is one of the most common situations where arborist reports and replanting plans are required.
Routine Maintenance vs. Tree Removal
Routine maintenance—like pruning for clearance, deadwood removal, and plant health care—is generally different from tree
removal. However, excessive pruning
that effectively removes the canopy can be treated like removal.
- Cutting a tree down to a stump without approval is rarely allowed
- Topping or heavy reduction can trigger enforcement issues
- If you’re unsure, confirm whether the work qualifies as maintenance or removal before proceeding
Do I need a permit?
In
Seattle, many tree removals
do require a permit, but the answer depends on several factors — including
tree size, species, location, and the reason for removal. Trees regulated by the Seattle Department of Construction & Inspections (SDCI) include
significant trees, exceptional trees, and trees located in environmentally critical areas (ECAs) such as steep slopes, shorelines, and wetlands. In general, removing a regulated tree requires prior approval from the City.
That said,
not all tree removals require a permit. Certain situations — such as
hazardous trees, emergency removals after storms, or trees interfering with utilities — may qualify for exemptions or expedited review. Even in these cases,
documentation and notification are often still required, and the City may request an arborist assessment to justify the work after the fact.
Because Seattle’s tree regulations are nuanced and site-specific, the safest approach is to
verify permit requirements before any removal. A certified arborist can help determine whether your tree is regulated, whether an exemption applies, and what documentation is needed to stay compliant and avoid penalties.
Understanding Seattle’s Tree Permit Requirements
In Seattle,
tree removal rules are not based on a single diameter threshold alone. Whether a permit is required depends on
where the tree is located, how the property is zoned, and how the tree is classified under the Seattle Municipal Code.
On
private property, a permit may be required if the tree is considered a
significant tree, is located within an
Environmentally Critical Area (ECA) such as a steep slope or shoreline, or if the removal is associated with
development, construction, or grading activities. Trees located on public property—such as
street trees in planting strips or rights-of-way—are regulated separately and generally require approval through the City of Seattle or SDOT.
Because Seattle’s tree regulations vary by situation, the safest way to determine whether a permit is required is to evaluate:
- The
tree’s location (private lot vs. right-of-way)
- The
site conditions (ECA, shoreline, steep slope)
- The
scope of work (maintenance, emergency removal, or development)
- The
tree’s classification under city code

Are There Any Permit Exemptions?
Seattle does allow
limited exceptions for trees that pose an
immediate hazard to life or property, such as trees that have failed or are at imminent risk of failure following storms or structural damage. However, these situations are
not blanket exemptions.
In most cases:
- The hazard must be
documented by a qualified arborist
- The removal must be
justified with photos, reports, or assessments
- Post-removal notification or documentation may still be required
Emergency removals involving street trees, significant trees, or trees within ECAs often have additional requirements, even when safety is the primary concern. Removing a tree without proper authorization can result in fines, replacement obligations, or enforcement action.
Because of these nuances, homeowners are strongly encouraged to consult a Seattle-experienced certified arborist before removing a tree—even in urgent situations.
How the Seattle Tree Removal Permit Process Works
Seattle’s tree removal permitting process is administered primarily through the
Seattle Department of Construction & Inspections (SDCI) and is designed to evaluate the
impact, necessity, and mitigation associated with removing regulated trees.
While the exact process varies by situation, most permit reviews follow a similar structure.
Step 1: Determine Whether the Tree Is Regulated
Before applying, it’s important to confirm whether the tree is classified as:
- A
significant or exceptional tree
- Located within an
Environmentally Critical Area (ECA)
- A
street tree or tree in the public right-of-way
- Associated with
development or construction activity
This determination drives whether a permit is required and which review path applies.
Step 2: Prepare Supporting Documentation
Most applications require documentation such as:
- Tree location and size
- Reason for removal
- Site plans or survey information
- Photos or arborist documentation (especially for hazards)
- Proposed mitigation or replacement plan, if applicable
For hazardous or disputed trees, the City may request an
arborist report prepared by a qualified professional.
Step 3: Submit the Application to SDCI
Applications are submitted through the City of Seattle’s permitting system. Review timelines vary depending on:
- Tree classification
- Property zoning
- Whether the site is within an ECA
- Whether the removal is tied to a larger project
Some applications are reviewed administratively, while others require additional environmental or land-use review.
Step 4: City Review and Decision
SDCI evaluates the application based on:
- Tree health and condition
- Environmental impact
- Development context
- Compliance with Seattle Municipal Code
If approved, the permit may include
conditions, such as replacement planting, fees, or limits on timing.
Step 5: Complete the Work and Close Out Requirements
Once approved, removal must be performed according to permit conditions. In some cases,
post-removal documentation or inspections may be required to close out the permit.
