Building & Planning


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.

Cowlitz PermitQ

Our 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.  

Please remember that all originally-produced PDF documentation shall be submitted electronically.  Any replications of the originals, including scanned copies or size-adjusted versions, shall not be accepted unless pre-approved.

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.
