ZIP code 94305

ZIP 94305 is a mid-size town in Santa Clara County, California, with 17,912 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #856 of 1,803 ranked by population — larger than 52% of them. The median age here is 22.6 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 94305 earn a median of $72,470 a year, 7.7% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 17.5% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 94305 is valued at $2,000,001, 559.2% above the national figure, while median gross rent runs $1,937 a month, 37.8% above the national figure, or roughly $23,244 across a full year. A household on the local median income would put about 32.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 27.6×, 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. 26.6% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 27.6× 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. A median age of 22.6 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.

ZIP 94305 is tabulated inside Santa Clara County, California, one of 58 ZIP areas the Census publishes for that county and 1,803 across California. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. 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 94305 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 94305 reports a median household income of $72,470, 55% below the $162,569 county median, and 19% below the $89,916 typical CA ZIP.

Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,937 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

California charges 7.25% statewide, and local governments overlapping 94305 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 94305 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.
