When you decide to make home improvements through remodeling and additions, there is a three-year property tax relief program available.
NOTE: This exemption may not be claimed on the same dwelling more than once in a five-year period. This five-year period begins the first year the exemption appears on the county's assessment roll.
According to RCW 84.36.400, any physical improvements to a single-family dwelling upon real property are exempt from property tax for three assessment years after the improvements are completed to the extent that the improvement represents 30% or less of the value of the original structure.
NOTE: Commencing with tax year 2021, physical improvements to a single-family dwelling includes constructing an accessory dwelling unit, whether attached to or within the single-family dwelling or as a detached unit on the same real property.
"Physical improvement" means any addition, improvement, remodel, renovation, or structural enhancement that materially adds to the value of an existing single family dwelling. It is an actual, material, and permanent change that increases the value of the dwelling.
Physical improvement includes the addition of a garage, carport, patio, or other improvement to the dwelling that materially adds to its value.
Physical improvement does not include a swimming pool, outbuilding, fence, landscaping, barn, shed, shop, or other item that enhances the land upon which the dwelling stands, but is not common to or normally recognized as a structural component of a single-family dwelling.
