This bill amends the existing property tax exemption statute RCW 84.36.805. It allows otherwise exempt property to be used by other individuals or groups for up to 50 days per calendar year without voiding the exemption, but limits uses for pecuniary gain or to promote business activities to 15 of those days (setup and takedown days are excluded from the counts). If those day limits are exceeded in an assessment year, the exemption is removed for the affected portion of the property for that assessment year. These are changes to the conditions and consequences for retaining a property tax exemption, not creation of a new crime. The bill also creates specific exceptions and adjustments: property exempt under RCW 84.36.037 used for a qualifying farmers market is exempt from the 15and 50-day limits and may be used up to 53 days when all income is used for capital improvements, maintenance and operation, or exempt purposes. The 15-day limit is increased to 50 days for regularly scheduled fundraising activities on property exempt under RCW 84.36.037. The act states that RCW 82.32.805 and RCW 82.32.808 do not apply to it. The changes apply to taxes levied for collection in 2027 and thereafter; Section 1 expires January 1, 2033, and Section 2 takes effect January 1, 2033. Affected parties named include nonprofit organizations, associations, and corporations holding exemptions under the cited chapter, limited equity cooperatives, certain governmental entities and housing authorities, and operators of qualifying farmers markets. The text references "the department" having access to books but does not identify which agency that is. Several referenced definitions and RCW sections (for example the definition of "qualifying farmers market") are not included in the provided text, so the full scope depends on those external provisions.

Nonprofit owners of tax‑exempt property will be able to host outside groups or events on their property more often without automatically losing their exemption: up to 50 days a year of general use is allowed, but only a limited number of those days may be used for money‑making or business promotion before a portion of the property could lose its exemption for that assessment year. This gives nonprofits and operators of qualifying farmers markets more room to generate event income or hold fundraisers (farmers markets get extra days and special allowances if proceeds are used for capital, maintenance, or exempt purposes, and certain fundraising limits are increased), but they will need to track days carefully because exceeding the caps can trigger additional property tax bills. These changes start affecting tax collections in 2027 and include a timed transition where one set of provisions expires January 1, 2033 and another takes effect that same day. Who enforces the day counts and exactly which markets or activities qualify depends on other statutes and an unnamed department referenced in the text, so implementation details, tracking and enforcement procedures are not clear from the provided facts.
