Valuation limits
Washington has no individual parcel assessed-value cap. County assessors value property at 100% of true and fair market value; regular taxing-district levy revenue is generally limited to a 1% annual increase plus new construction under RCW 84.55, subject to voter-approved lid lifts and other statutory rules. The 1% constitutional levy limit constrains aggregate regular levies, not an individual parcel's value.
For a valuation appeal, use the appeal date in the tax and filing section above. Keep your notice, supporting evidence, and proof of submission.
