A King County value notice starts an appeal clock that is not the same for every property. Some areas close as soon as Monday, Nov. 2, while others still have a few more weeks to file with the Board of Appeals and Equalization.

The county gives owners until July 1 or 60 days after the notice date, whichever is later, so the deadline depends on when notices went out in each area. Still open for Nov. 2 are areas 49, 56, 57, 60, 70, 90 and 94. The Nov. 9 group includes 38, 45 and 96, followed by 68, 91 and 93 on Nov. 16, and 26, 27, 28, 29, 52, 53, 54, 55, 61, 62 and 88 on Nov. 23.

The area number appears on the notice and on the assessor's parcel page. Appeals can be filed online or by mail, but not by email. Recent sales of similar nearby homes compared with the county's assessed value are the kind of evidence that usually carries the most weight.

A lower value is not automatic, and the board can leave the value alone or change it. For owners considering an appeal, the crucial details are the deadline tied to their area and the sales evidence available to support the case.
