ZIP code 99223

ZIP 99223 is a small city in Spokane County, Washington, with 35,848 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #66 of 605 ranked by population — larger than 89% of them. The median age here is 41 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 ZIP 99223 earn a median of $91,377 a year, 16.3% above the national figure of $78,538. 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 6.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 99223 is valued at $457,200, 50.7% above the national figure, while median gross rent runs $1,221 a month, 13.2% below the national figure, or roughly $14,652 across a full year. A household on the local median income would put about 16% 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 5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 66.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.

ZIP 99223 is tabulated inside Spokane County, Washington, one of 40 ZIP areas the Census publishes for that county and 605 across Washington. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 99223 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 99223 reports a median household income of $91,377, 23% above the $74,302 county median, and 13% above the $80,861 typical WA ZIP. Owner-occupied homes are valued at a median of $457,200, 24% above the county figure and 9% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,221 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 99223 carries 9% at the register, assembled from the Spokane jurisdiction stack: the Washington state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 99223 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

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 99223 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.
