Alki property taxes track Seattle’s 0.99 percent effective rate, but the King County mass-appraisal model misfires on Alki homes in distinctive ways. Here is how to spot it.
Alki is West Seattle's beach neighborhood, with Puget Sound frontage, Olympic Mountain views, and a tight residential mix on the peninsula's western tip. 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 an Alki home depends on the model’s neighborhood-level math, which is where the gaps appear.
How are Alki property taxes calculated?
King County reassesses every Seattle property every year, including every parcel in Alki. 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 Alki-specific factors that buyers actually price into offers — and that is where most appeals are won. Anchored by Alki Avenue SW, Alki Beach Park, and the Statue of Liberty replica, Alki’s housing stock has its own quirks the citywide model does not always capture.
Where does the Assessor get Alki wrong?
Alki's overassessment pattern is waterfront-tier overshoot. Direct Alki Avenue beachfront parcels carry true premiums; second-row and interior homes price meaningfully lower. The model can pull non-waterfront comps upward when adjacent waterfront sales drive the average.
Identify your specific row — beachfront, second-row with view, or interior. Comps should match the tier. Beachfront comp sets will overstate non-beachfront homes; interior comps will understate true beachfront homes.
Alki comps to itself first. North Admiral and the western edge of West Seattle Junction are secondary sets for non-waterfront homes. A tight comp set drawn from genuinely similar homes — same submarket, similar size and age, similar condition — is what moves an Alki appeal at the King County Board of Equalization.
What does an Alki appeal actually look like?
Alki 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 an Alki 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 Alki home (recent sale prices around $1,200,000, assessed values somewhat lower) pulls roughly $1,100 a year off the bill, and reductions tied to documented evidence often land larger. Most Alki homes have at least one angle worth pursuing — the question is which one.
