Registered Seattle Tree Service Provider – Why It Matters

Sound Tree Care LLC is a fully registered, licensed, and Seattle-approved tree service provider. Our team is authorized to perform tree removal, pruning, and arborist work that complies with all Seattle tree regulations. Our credentials include:

  • Seattle Department of Construction & Inspections (SDCI) – License: TSP-18505
  • Seattle Department of Transportation (SDOT) – License: TSP-18505

As a long-standing Seattle arborist company, we specialize in navigating Seattle tree removal permits, SDCI Tree Code requirements, SDOT street tree regulations, and environmentally critical area (ECA) protections. We ensure every pruning, removal, or risk assessment complies with city rules — preventing costly violations, delays, or rejections.

With an ISA Certified Arborist and TRAQ Qualified Tree Risk Assessor overseeing your project, you receive expert evaluations, precise documentation, and a streamlined permitting process tailored to Seattle’s regulations.


⚠️ Why it’s important:

Seattle Tree Codes, Permits, and Arborist Regulations (2025 Guides)

Tree work in Seattle is governed by one of the most complex municipal tree codes in Washington State. Depending on tree size, species, location, and zoning, pruning or removal may require permits, professional documentation, or review by the city. To help homeowners, HOAs, developers, and contractors navigate these rules, we’ve created a comprehensive 2025 guide to Seattle tree removal permits and tree code.

This guide explains when permits are required, how Seattle classifies Tier 1–3 and Exceptional Trees, how Environmentally Critical Areas (ECAs) affect allowable tree work, and when a Registered Tree Service Provider (RTSP) or ISA Certified Arborist is required. It also covers legal pruning vs. removal, mitigation and replanting requirements, and common compliance pitfalls that can lead to enforcement actions. Reviewing this guide before starting work can help you avoid fines, delays, and costly violations.

Seattle Tree Care: A Comprehensive FAQ Guide to understanding the nuances of Seattle tree code.


Whether you’re a seasoned tree enthusiast or a new homeowner, this guide equips you with everything you need to keep your Seattle trees safe and healthy. Learn when you need a permit, how to find a registered provider, and how to identify common tree issues — all backed by local regulations.

  • Seattle tree regulations, the rules of the road.

    Seattle, known for its lush greenery, has specific regulations in place to protect its valuable trees. Before you start any tree work on your property, it's essential to familiarize yourself with these rules of the road.

    The Seattle Department of Construction and Inspection (SDCI) oversees tree regulations in the city. They have established guidelines to ensure proper tree care and preservation. These regulations apply to both public and private property and help maintain the city's urban forest.

    To determine if your tree work requires a permit, consider factors such as tree size, location, environmentally critical areas, the type of work you plan to undertake. Certain exemptions exist for minor pruning and tree removal, but it's crucial to check the rules to avoid any potential penalties.

  • Can any Seattle tree work be done without a permit?

    While some tree work in Seattle can be done without a permit, it's important to assess the specific circumstances to determine if a permit is necessary. Typically, pruning of branches less than 2" in diameter that comprise less than 15% of the trees canopy is allowed. Removal of  a tree under 6" DSH is allowed as well.


    However, if you plan to remove a tree or perform extensive pruning that could potentially harm the tree, a permit from the SDCI may be required. It's always advisable to consult the SDCI regulations or seek professional advice to ensure compliance with the city's tree care guidelines.

  • What is a Seattle Department of Construction and Inspection registered tree service provider and how do I find one?

    A Seattle Department of Construction and Inspection (SDCI) registered tree service provider is a professional or company that has met certain criteria and obtained the necessary certifications to offer tree care services in Seattle. These providers have demonstrated their expertise in tree care and are well-versed in the city's regulations.

    To find a registered tree service provider, you can refer to the SDCI website, which maintains a list of approved providers. Additionally, you can seek recommendations from neighbors, friends, or local gardening associations. When hiring a tree service provider, it's important to verify their registration and ensure they have the required insurance coverage.

  • What is a Seattle Department of Transportation Tree Service Provider and how do I find one?

    The Seattle Department of Transportation (SDOT) Tree Service Provider is a specialized group of professionals who are authorized to perform tree services in the public right-of-way. These providers have expertise in handling trees located near roads, sidewalks, and other public areas.

    To find a Seattle Department of Transportation Tree Service Provider, you can visit the SDOT website, where they maintain a directory of registered providers. It's crucial to engage a licensed professional for tree work in public areas to ensure the safety of pedestrians, vehicles, and property.

  • How can Sound Tree Care help with Seattle tree permitting?

    Navigating the tree permitting process in Seattle can be complex and overwhelming. That's where Sound Tree Care comes in. As a trusted tree care company in Seattle, we have extensive experience with the city's regulations and can guide you through the permitting process.

  • Seattle tree permitting resources and TIP sheets

    - Tree pruning guidelines

    - Tree protection during construction
