East Renton Highlands, WA population, income and ZIP codes

East Renton Highlands CDP is a mid-size town in Washington, with 12,241 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #111 of 639 ranked by population — larger than 82% of them. The median age here is 41.3 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 East Renton Highlands CDP earn a median of $140,048 a year, 78.3% above the national figure of $78,538 and 55% above the $90,592 median for the 393 Washington cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 2.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in East Renton Highlands CDP is valued at $709,300, 133.8% above the national figure and 51% above the $468,400 peer median, while median gross rent runs $2,697 a month, 91.8% above the national figure, or roughly $32,364 across a full year. A household on the local median income would put about 23.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 90% 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
