Median Year of HOUSE Construction by Bay Area County or Region (+ Sacramento County)*
Different parts of the Greater Bay Area were built out at very different times: Prior to 1950, and the postwar building boom, many local counties were relatively empty places. Though every Bay Area County includes both older houses – typically going back to the late 1800 ’s – and brand new houses, these median dates provide an idea of the relative age of county housing. Outside of San Francisco, home construction often followed bridge, highway, tunnel and BART construction. And different parts of counties were often built out at very different periods, usually radiating out gradually from city and town cores. Condos were typically constructed from the late 1970 ’s forward, though San Francisco has thousands originally built as apartments in 1900 to 1930. • 1928: San Francisco: 1914 for north, NE & central districts; 1940 for south and SW districts • 1936: Greater Oakland-Berkeley region (north Alameda County) • 1955: San Mateo County • 1960: Marin County • 1966: Santa Clara County: The county with the largest population and number of housing units • 1969: South Alameda County • 1971: Santa Cruz & Monterey Counties • 1973: Napa County: The county with the smallest population and number of housing units • 1976: Contra Costa (In Lamorinda – Lafayette, Moraga, Orinda – the median year is 1961) • 1979: Sonoma County • 1982: Sacramento County • 1986: Solano County
Median year of construction is that year at which half the houses were built earlier and half later.
