ZIP code 98177

ZIP 98177 is a mid-size town in King County, Washington, with 20,506 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #171 of 605 ranked by population — larger than 71% of them. The median age here is 47 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 98177 earn a median of $162,607 a year, 107% above the national figure of $78,538. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 7.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 98177 is valued at $995,700, 228.2% above the national figure, while median gross rent runs $2,123 a month, 51% above the national figure, or roughly $25,476 across a full year. A household on the local median income would put about 15.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 6.1×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 86.6% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 6.1× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

This is a mid-sized suburban ZIP inside a county that is split across many delivery areas.

Against its own county, 98177 reports a median household income of $162,607, 28% above the $127,093 county median, and 101% above the $80,861 typical WA ZIP.

Rent is reported gross — the contract amount plus tenant-paid utilities — at $2,123 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Washington charges 6.5% statewide, and local governments overlapping 98177 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 98177 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
