Madrona property taxes track Seattle’s 0.99 percent effective rate, but the King County mass-appraisal model misfires on Madrona homes in distinctive ways. Here is how to spot it.
Madrona is a hillside neighborhood between Capitol Hill and Lake Washington, with old-Seattle character, a tight commercial node at 34th and Union, and a mix of craftsmans and Victorians. 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 Madrona home depends on the model’s neighborhood-level math, which is where the gaps appear.
How are Madrona property taxes calculated?
King County reassesses every Seattle property every year, including every parcel in Madrona. 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 Madrona-specific factors that buyers actually price into offers — and that is where most appeals are won. Anchored by 34th Avenue, Union Street, and Madrona Park, Madrona’s housing stock has its own quirks the citywide model does not always capture.
Where does the Assessor get Madrona wrong?
Madrona's overassessment pattern is hillside view-rating mistakes. The east slope of the hill catches Lake Washington and Cascade views; the west slope and flat top do not. The model assigns view ratings that sometimes overstate or understate depending on parcel orientation and tree obstructions.
Walk the property and confirm what is actually visible. A tree line, a neighbor's addition, or a downward slope can erase a view the model still credits. Photo evidence is concrete and persuasive at the BOE.
Madrona comps to Leschi (south, also on the hillside) and Madison Valley (north). Mount Baker as a tertiary. A tight comp set drawn from genuinely similar homes — same submarket, similar size and age, similar condition — is what moves a Madrona appeal at the King County Board of Equalization.
What does a Madrona appeal actually look like?
Madrona 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 Madrona 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 Madrona home (recent sale prices around $1,400,000, assessed values somewhat lower) pulls roughly $1,300 a year off the bill, and reductions tied to documented evidence often land larger. Most Madrona homes have at least one angle worth pursuing — the question is which one.
