Everything Kent homeowners, HOAs, and contractors need to know about tree removal permits, significant tree rules, ECAs, TPZ requirements, and replanting in 2025.

Thinking about removing or pruning a tree in Kent, WA? 🏑🌲 Kent has its own tree protection code that can be tricky — especially if your property has significant trees, Environmentally Critical Areas (ECAs), or new construction planned.

 This guide explains when a tree removal permit is required, what counts as a significant tree, and how an ISA Certified Arborist can help keep your project compliant.

βœ… When You Need a Tree Removal Permit in Kent

Kent typically requires a permit when any of the following apply:

  • 🌳 Significant Trees: Removal of trees ≥6″ DBH (diameter at breast height) on single-family lots, or larger thresholds on multifamily/commercial sites.
  • πŸ—οΈ Construction or Development: Any removal tied to building permits or land clearing usually triggers a review.
  • 🌿 ECAs (Environmentally Critical Areas): Steep slopes, wetlands, and streams have strict protections.
  • 🌐 Street Trees: Trees in the right-of-way or planting strips require a city permit and often must be handled by a Registered Tree Service Provider.
⚠️ Not sure? An assessment by an ISA certified arborist can document hazards and clarify permitting needs.

πŸ“œ Highlights of Kent’s 2025 Tree Code

  • Tree Density & Replacement:
  • Removing significant trees typically requires replanting at a 1:1 or 2:1 ratio.
  • Replacement trees must be on Kent’s approved species list and usually planted at 1.5″–2″ caliper minimum.
  • Construction Protection:
  • Install Tree Protection Zones (TPZs) πŸ›‘ to protect root systems during work.
  • See our Tree Protection Zones (TPZ) Explained guide for full details.
  • Hazard Trees:
  • Dead, diseased, or hazardous trees may qualify for expedited removal with an arborist’s report.

🌲 Significant, Landmark & Street Trees in Kent

  • Significant Trees: Generally ≥6″ DBH on residential lots.
  • Landmark / Heritage Trees: Specially designated; removal requires extra review.
  • Street Trees: Located in the city’s right-of-way or planting strip — removal without a permit can lead to fines and penalties.

πŸ› οΈ Working in ECAs & Steep Slopes

If your property is in an ECA (steep slope, wetland buffer, stream corridor, or shoreline), Kent will require:

  • A critical area review or variance before removal.
  • A Tree Inventory & Protection Plan (prepared by an ISA Certified Arborist).
  • Justification for any TPZ modifications due to lot lines, existing pavement, or structures.

πŸ“ Documents You’ll Need for Kent Tree Permits

  • Tree Inventory Table — DBH, species, canopy spread, health condition.
  • Site Plan with TPZ fencing — show driplines and critical root zones.
  • Risk Assessment Report — when claiming hazard tree status.
  • Replanting Plan — species, size, and placement to meet Kent’s canopy requirements.
πŸ“„ Our Kent Tree Services include TRAQ risk assessments, site plans, and TPZ documentation to make permitting smoother.

🌱 Replanting Requirements & Native Options

When removal is approved, Kent requires replanting:

  • Usually 1:1 or 2:1 tree replacement ratio.
  • Approved species list includes Douglas fir, western red cedar, vine maple, shore pine, and other climate-adapted trees.
  • ECAs often require native-only species.

πŸ’Έ Penalties for Unpermitted Tree Removal

Kent enforces strict penalties:

  • Fines up to the appraised value of the tree 🌳.
  • Stop-work orders and construction delays.
  • Higher penalties in ECAs and shoreline areas.
