New Permit Process Improvements Take Effect March 1, 2025
A new state law, SB5290, reduces permitting timelines. To comply, we’re making changes:
- We will only accept complete application packets. Submittal checked at counter before intake.
- Concurrent Critical Areas Review required when you apply.
- A Critical Areas Review is the official permit required if a project is in proximity (within 400 feet) to critical areas.
- Projects near critical areas may require additional biological reports by experts. Find details on the Critical Areas Review webpage.
- To ask questions about your specific project, visit the permit office or contact us at planning@co.thurston.wa.us.
- New forms & checklists available now on our Applications & Forms page.
About Critical Areas & How to See if they are mapped on a Property
- These areas are considered critical areas. See the Critical Areas Ordinance Code - Title 24.
- Check to see if a property is mapped with critical areas. There are three ways:
- Open the critical areas property information sheet for a specific property using the parcel number. To get parcel number enter address into this form first.
- Check for critical areas using the county's online Permitting map. (For reference only. Current ground conditions at a property now or at the time of application may not be fully represented on map.)
- Visit the Permit Office Monday - Friday between 8 a.m.- 3:45 p.m. See Office Hours & Location.
Where to Find the CAD Determination Form & More information
- Go to the Applications & Forms page (scroll down to Critical Areas).
- For more information, thoroughly review the Permitting Process Steps on the Plan Your Project page.

November 25, 2024 - A new Washington state law goes into effect on January 1.

- Permit fees change: The new fees will be posted in 2025.

- Application review timelines and standards: Brings the county's application review timelines into line with state law.
