Periodic Update Resources

Every county and city in the state is required to conduct a periodic update of its comprehensive plan and development regulations, though the obligation varies depending on whether the jurisdiction is fully or partially planning (RCW 36.70A.130(1)). Growth Management Services provides resources for completing the periodic update.

Periodic Update Status

Counties and cities must be up-to-date with the requirements of the GMA, including the periodic update requirements, to be eligible for grants and loans from certain state infrastructure programs. Growth Management Services maintains a list of local governments’ periodic update status and GMHB orders to help applicants and funding programs implement this requirement. When you take legislative action that meets your update requirement, make sure you send the adopting ordinance or legislation to Commerce, clearly identifying it as part of the update. This will allow Commerce to keep information about your city or county complete and up to date.

For more information and to see a list of jurisdictions, please read the GMA Periodic Update and GMHB Status Report (PDF).

The Status Report is advisory and is based on the most recent information available to Commerce on the date it is published. If you believe the information on the report is not accurate, please contact William Simpson at
