(1) The term “single family dwelling” shall mean a detached dwelling unit and the lot on which the dwelling stands which is designed for, and not occupied by, more than one family. Said dwelling unit must meet the definition of real property contained in WAC 458-12-010 and RCW 84.04.90.
(2) The term “physical improvement” shall mean any addition, improvement, remodeling, renovation, structural correction or repairs which shall materially add to the value or condition of an existing dwelling.

WAC 458-16-081 EXEMPTION - FILING - AMOUNT - LIMITS
Any physical improvement to an existing single family dwelling upon real property shall be exempt from taxation for three assessment years; provided, that no exemption shall be allowed unless a claim is filed with the county assessor of the county in which the property is located prior to completing the improvement. The claim shall be on such forms as prescribed by the department of revenue and supplied by the county assessor.
The assessor, upon receipt of the claim, shall determine the value of the single family dwelling prior to the improvement. This valuation may be arrived at by either a new physical appraisal or a statistical update of the current assessed value.
Upon written notification of the completion of the improvement by the applicant, the Assessor shall revalue the dwelling by means of a physical appraisal; provided, that the valuation prior to commencing the improvement, whether by a new physical appraisal or statistical update, and the physical appraisal upon completion of the improvement shall not obviate the requirement for a physical appraisal set forth in RCW 36.21.070. The difference of the two values shall be the amount of the exemption and shall be deducted from the value of the dwelling after the completion of the improvement or any subsequent value determined according to chapters 84.41 RCW or 84.48 RCW; provided, the amount of the exemption shall not exceed thirty percent (30%) of the value of the dwelling prior to the improvement, and, provided further, that in no event will the assessed value of the dwelling unit, after deduction of the exemption, be less than it was prior to the improvement.
The cost of the physical improvement shall not be construed as being the dominant factor in determining the exemption.
The exemption shall be allowed on the property for the three assessment years following completion of the improvement. If at any time the property does not meet the definition contained in WAC 458-16-080(1), the exemption shall be canceled.
This exemption shall not be allowed on the same dwelling more than once in a five-year period, calculated from the date the exemption first affected the assessment roll.
