(1) Except as provided in subsection (3) of this section, whenever property classified and valued as eligible historic property under RCW 84.26.070 becomes disqualified for the valuation, there shall be added to the tax an additional tax equal to:

(a) The cost multiplied by the levy rate in each year the property was subject to special valuation; plus

(b) Interest on the amounts of the additional tax at the statutory rate charged on delinquent property taxes from the dates on which the additional tax could have been paid without penalty if the property had not been valued as historic property under this chapter; plus

(c) A penalty equal to twelve percent of the amount determined in (a) and (b) of this subsection.

(2) The additional tax and penalties, together with applicable interest thereon, shall become a lien on the property which shall have priority to and shall be fully paid and satisfied before any recognizance, mortgage, judgment, debt, obligation, or responsibility to or with which the property may become charged or liable.

(3) The additional tax, interest, and penalty shall not be imposed if the disqualification resulted solely from:

(a) Sale or transfer of the property to an ownership making it exempt from taxation;

(b) Alteration or destruction through no fault of the owner; or

(c) A taking through the exercise of the power of eminent domain.
