ZIP code 94127

ZIP 94127 is a mid-size town in San Francisco County, California, with 20,710 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #803 of 1,803 ranked by population — larger than 55% of them. The median age here is 47.6 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 94127 earn a median of $205,429 a year, 161.6% 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 5.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 94127 is valued at $1,897,700, 525.5% above the national figure, while median gross rent runs $3,501 a month, 149% above the national figure, or roughly $42,012 across a full year. A household on the local median income would put about 20.5% 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 9.2×, 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. 81.8% 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. 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 9.2× 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.

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.

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

Owner-occupied homes are valued at a median of $1,897,700, 26% above the county figure and 202% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $3,501 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 94127 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 94127 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.
