Historic Property

Property owners who register their historic properties make a commitment to preserving these sites. Thurston County believes in the preservation of our cultural and historic assets. Preservation of significant historic structures is needed so that current and future generations can appreciate our County’s rich past and invest in our promising future.

For definitions and more information see RCW 84.26

According to RCW 84.26.020, the actual cost of substantial improvement to eligible historic property (which cost is 25 percent or more of the assessed value of the historic structure prior to rehabilitation) may be excluded from the assessed value of such property for a period of ten years. Applications for this exemption may be obtained at the Assessor's office by calling (360)867-2200 or online by selecting the appropriate Historic Preservation Board application site below.
