Seattle voters decide library levy in August 4 primary

Seattle voters are deciding Tuesday, August 4, whether to approve Proposition 1, a seven-year property-tax levy for The Seattle Public Library. If approved, the measure would replace the current 2019 library levy, which expires December 31, 2026.

King County Elections says initial results will be posted shortly after 8 p.m. Tuesday. Those figures will be preliminary, with updates scheduled on weekdays at 4 p.m. until certification on August 18, 2026.

What Proposition 1 would fund

The measure would authorize an estimated additional tax rate of $0.23 per $1,000 of assessed value. Official ballot materials estimate that it would raise approximately $479.76 million over seven years, with collections beginning in 2027 and continuing through 2033.

The levy is intended to fund five broad categories of library services: operating hours and access, collections, technology, maintenance and administration. The ordinance lists examples such as neighborhood-branch and Central Library access, physical and digital materials, technology upgrades, digital-equity work, building maintenance and public reporting.

The ordinance also identifies capital work, including a seismic retrofit of one landmarked library branch identified as highly vulnerable in the city’s unreinforced-masonry study. The listed program elements are illustrative; annual operations plans and capital budgets would guide spending if the measure passes.

Why the existing levy matters

The ballot ordinance says the 2019 Seattle Library Levy provides approximately 33% of the library’s overall 2026 budget. It also says the levy is the primary support for the library’s capital budget, supplemented by real-estate-excise-tax revenue.

Because the 2019 levy ends at the close of 2026, Proposition 1 is structured as a replacement rather than an extension of that measure. If voters reject Proposition 1, the existing levy would still expire at the end of 2026.

The official explanatory statement says the state’s senior-citizen and disabled-persons property-tax exemption applies to the increased levy amount. The proposed rate and total proceeds are estimates in the ballot materials, not guaranteed final collections.

When the result becomes final

King County Elections will publish election-night results shortly after 8 p.m. and update them on weekdays at 4 p.m. The county’s schedule lists certification for August 18, 2026.

Because ballots can be counted after election night, the first reported margin will not necessarily be the final outcome. Seattle residents watching Proposition 1 should treat Tuesday night’s figures as an initial snapshot until the county completes its updates and certifies the election.
