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.

Building Inspectors will begin their Fall/Winter Schedule:

Effective Monday, November 19th, building inspections will be held
 Monday, Tuesday, Wednesday, and Fridays 8 am to 5 pm, and
Thursdays 8 am to 4 pm 
(excluding holidays).

Inspections in the County are conducted daily; refer to seasonal schedule below.  Unless specifically requested otherwise, inspection requests received prior to 7:00 AM will be conducted same business day. Inspection requests received after 7:00 AM will be conducted the following business day.  For requests made by telephone, please use a land-line.


One-Stop Permit Center
In our ongoing efforts to provide excellent customer service, we have a one-stop permit center available with representatives on-duty at all times from each division. Customers and the general public are welcome to visit the permit center in person or reach us by telephone during business hours.

Questions regarding regulations, the permitting process, development potential, construction activities, etc., will be directed to knowledgeable staff that can provide information and records. Please visit with us early in the development of your project so that we can be of the greatest assistance!
