WA State Special Valuation for Historic Properties

About This Program

Washington State's Special Valuation program for historic properties allows approved rehabilitation costs to be subtracted from the property's assessed value for up to 10 years, reducing annual property taxes. Unlike the federal 20% credit, this program is available for owner-occupied historic residences as well as commercial properties. Projects must be reviewed and approved by the local historic preservation board and meet preservation standards.

A $50,000 qualifying rehabilitation subtracted from assessed value at a 1% effective tax rate saves $500/year for 10 years ($5,000 total).
