Beacon Hill property taxes track Seattle’s 0.99 percent effective rate, but the King County mass-appraisal model misfires on Beacon Hill homes in distinctive ways. Here is how to spot it.
Beacon Hill is the long ridge running south of downtown, with light rail stations, panoramic views west to Seattle and east to the Cascades, and a diverse residential character. 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 Beacon Hill home depends on the model’s neighborhood-level math, which is where the gaps appear.
How are Beacon Hill property taxes calculated?
King County reassesses every Seattle property every year, including every parcel in Beacon 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 Beacon Hill-specific factors that buyers actually price into offers — and that is where most appeals are won. Anchored by Beacon Avenue, the Beacon Hill light rail station, and Jefferson Park, Beacon Hill’s housing stock has its own quirks the citywide model does not always capture.
Where does the Assessor get Beacon Hill wrong?
Beacon Hill's defining overassessment pattern is airport noise. Sea-Tac's official airport noise zone clips the southern half of Beacon Hill, and Boeing Field operations affect the northern half. Both produce documentable home-value discounts the mass-appraisal model rarely captures.
Pull the Port of Seattle's official Sea-Tac noise map and overlay your parcel. If you are inside the official Sea-Tac noise zone, the discount is documentable and BOE-accepted. For homes near Boeing Field, the FAA's flight-path maps fill the same role.
Beacon Hill comps to Mount Baker (east), Columbia City (south), and Georgetown (west) for industrial-adjacent homes. A tight comp set drawn from genuinely similar homes — same submarket, similar size and age, similar condition — is what moves a Beacon Hill appeal at the King County Board of Equalization.
What does a Beacon Hill appeal actually look like?
Beacon 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 Beacon 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 Beacon Hill home (recent sale prices around $750,000, assessed values somewhat lower) pulls roughly $700 a year off the bill, and reductions tied to documented evidence often land larger. Most Beacon Hill homes have at least one angle worth pursuing — the question is which one.
