Building & Planning

Welcome!

The Building and Planning Department was established by the Board of County Commissioners to carry out the effective and reasonable administration of developmental laws and standards and to accomplish county planning, building permit coordination, environmental coordination, fire / life safety, and environmental health.

It is our goal to provide fast, fair, consistent, and friendly services to the citizens of Cowlitz County. The Building and Planning Department provides a wide-variety of permitting services through the Building Division, the Planning Division and the Operations Division.

Emergency Burn Ban In Effect

Effective 12:01 AM Friday, April 16, 2021, Cowlitz County, in cooperation with neighboring Counties, will be enacting restrictions on outdoor burning.  Lack of precipitation, current dry conditions, and multiple wildland brush fires have prompted this decision.  The emergency burn ban will be in place temporarily until the conditions improve but is expected to remain in effect until 12:01 AM Friday, April 23rd.  All land clearing, residential, and silvicultural burning will be restricted until further notice.  The Cowlitz County Fire Marshall is rescinding all burn permits issued prior to the burn ban; they can be reissued or extended when the ban is lifted.

Please see the Emergency Burn Ban Press Release for more guidelines on what is and is not allowed.

It's finally here! 

Our new Cowlitz Online Permit System.

Our new system is more user friendly and will allow for online permit submission, allow you to track the progress and status of your permits, make online payments, and reduce printing costs or unnecessary paperwork.  

As with any software transition, there will be bumps along the way.  We appreciate your patience as we navigate that process over the next couple months.  Additionally, we look forward to all feedback on your experience with the new system.

You will need to register for a Portal account in order to submit your permit application and access the other features of our new system.  If you already have an open/active permit, you will need to use the same email address that you used on the original permit.

Click the link below for an overview on how to set up your account and navigate the Portal.
