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.

The citizen access portion of our permit system can be found at the link above. Starting your own account will allow you to begin scheduling inspections, and keeping up to date on the status of your permit. In the coming months we will be adding to the list of permit types that you may apply for online and we’ll be adding an online payment option, too. Please note that only permits applied for after November 17, 2014 will be viewable on the new system. Older permits will continue to use the previous permit system portal.
