Maple Leaf property taxes track Seattle’s 0.99 percent effective rate, but the King County mass-appraisal model misfires on Maple Leaf homes in distinctive ways. Here is how to spot it.
Maple Leaf wraps around the Maple Leaf Reservoir Park, with Cascade views from its eastern blocks and a mix of mid-century ranches and modest craftsmans. 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 Maple Leaf home depends on the model’s neighborhood-level math, which is where the gaps appear.
How are Maple Leaf property taxes calculated?
King County reassesses every Seattle property every year, including every parcel in Maple Leaf. 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 Maple Leaf-specific factors that buyers actually price into offers — and that is where most appeals are won. Anchored by Maple Leaf Reservoir Park, 5th Avenue NE, and Northgate Way, Maple Leaf’s housing stock has its own quirks the citywide model does not always capture.
Where does the Assessor get Maple Leaf wrong?
Maple Leaf's overassessment pattern is east-side view overshoot. Homes on the east-facing slope of the reservoir hill get partial Cascade views and a price premium for them; homes on the flat top or west slope do not. The model can apply the premium too broadly.
Confirm your view rating against your actual view. If trees or other homes block what the model credits, photo evidence of the obstruction is the cleanest issue to challenge.
Maple Leaf comps to Roosevelt (south), Wedgwood (east), and Northgate (north) for non-view homes. A tight comp set drawn from genuinely similar homes — same submarket, similar size and age, similar condition — is what moves a Maple Leaf appeal at the King County Board of Equalization.
What does a Maple Leaf appeal actually look like?
Maple Leaf 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 Maple Leaf 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 Maple Leaf home (recent sale prices around $900,000, assessed values somewhat lower) pulls roughly $800 a year off the bill, and reductions tied to documented evidence often land larger. Most Maple Leaf homes have at least one angle worth pursuing — the question is which one.
