Delridge Property Taxes (Seattle): The 2026 Homeowner Guide

Delridge runs north-south along Delridge Way through the eastern half of West Seattle, with diverse housing stock, a long commercial spine, and a mix of older homes and recent infill. Seattle's 2026 median assessed value is $833,000 at a ~0.99 percent effective rate, about $8,000 a year, but the bill on a Delridge home turns on neighborhood-level math.

If your property tax bill feels too high, the savings math below uses your own numbers. For a personalized review of your Delridge home (a comp pull, a property record check, and a real savings estimate), enter your address on the homepage. The review is free; Fair Appeal only collects a percentage of first-year tax savings when the appeal actually wins.

How are Delridge property taxes calculated?

King County reassesses every Seattle property every year, including every parcel in Delridge. 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 Delridge-specific factors that buyers actually price into offers, and that is where most appeals are won. Anchored by Delridge Way SW, Westcrest Park, and the Longfellow Creek corridor, Delridge’s housing stock has its own quirks the citywide model does not always capture.

Where does the Assessor get Delridge wrong?

Delridge's overassessment pattern is corridor-frontage drag combined with submarket variance. Delridge Way commercial frontage discounts adjacent homes; interior blocks east of the corridor sit in a quieter market the model can handle inconsistently.

Identify whether your home is corridor-adjacent (within two blocks of Delridge Way) or interior. Comps should match. Interior Delridge has a different price character than the corridor, and mixing the two will weaken the case.

Delridge comps to North Delridge (north end) and South Delridge (south end). Highland Park is a tertiary set for southern Delridge homes. A tight comp set wins these cases.

What does a Delridge appeal actually look like?

Delridge 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 Delridge 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 Delridge home (recent sale prices around $700,000, assessed values somewhat lower) pulls roughly $600 a year off the bill, and reductions tied to documented evidence often land larger. Most Delridge homes have at least one angle worth pursuing, the question is which one.

FairAppeal handles the full process from review through hearing, and only charges a percentage of first-year tax savings if the appeal actually reduces your taxes. the 2026 window is still open.
