First Hill property taxes track Seattle’s 0.99 percent effective rate, but the King County mass-appraisal model misfires on First Hill homes in distinctive ways. Here is how to spot it.
First Hill packs three major hospitals, a streetcar line, and dense mid-rise residential into a small footprint just east of downtown. The 2026 King County Assessor median assessed value across Seattle is $833,000 at an effective rate near 0.99 percent, producing a citywide median bill around $8,000 — but the bill that lands on a First Hill home depends on the model’s neighborhood-level math, which is where the gaps appear.
How are First Hill property taxes calculated?
King County reassesses every Seattle property every year, including every parcel in First Hill. The Assessor’s mass-appraisal model weights square footage, year built, lot size, and recent neighborhood sales, then applies the combined Seattle levy rate (around 0.99 percent for 2026) to the result. Voter-approved levies for schools, transit, parks, and city services layer on top of the state and county base.
What the model rarely picks up are the property-specific and First Hill-specific factors that buyers actually price into offers — and that is where most appeals are won. Anchored by Madison Street, Boren Avenue, and Swedish Medical Center, First Hill’s housing stock has its own quirks the citywide model does not always capture.
Where does the Assessor get First Hill wrong?
First Hill is dominated by mid-rise condos. Overassessments here often track building-condition issues that the mass-appraisal model does not capture — aging mechanical systems, pending special assessments, and unit-specific problems like elevator-shaft noise or parking-garage proximity.
Pull HOA documentation including the most recent financial-reserves report. A reserve shortfall typically translates to upcoming special assessments, which buyers price in as a discount. That documentation is straightforward to present to the BOE.
First Hill comps to other First Hill buildings in the same era. The southern edge of Capitol Hill is a secondary set. A tight comp set drawn from genuinely similar homes — same submarket, similar size and age, similar condition — is what moves a First Hill appeal at the King County Board of Equalization.
What does a First Hill appeal actually look like?
First Hill homeowners appeal through the King County Board of Equalization, the same independent panel that hears every Seattle and King County appeal. The 2026 filing window runs through July 1, or 60 days after your Official Property Value Notice mails, whichever is later. The hearing is short, usually 15 to 30 minutes by phone, and the Board wants concrete evidence: comparable sales, documented condition issues, or an outright error in the property record.

Is a First Hill appeal worth filing?
At Seattle’s 0.99 percent effective rate, every $10,000 of assessed-value reduction is roughly $100 off the annual bill. A 10 percent reduction on a typical First Hill home (recent sale prices around $475,000, assessed values somewhat lower) pulls roughly $400 a year off the bill, and reductions tied to documented evidence often land larger. Most First Hill homes have at least one angle worth pursuing — the question is which one.
