South San Francisco


Westborough is one of South San Francisco’s largest post-war housing developments. Built on diary land, the one-time “Callan Park” (named after its developers) was annexed by South City in 1964 after flirting with becoming part of Daly City. Ultimately, Westborough added some 8,000 residents to South San Francisco, pushing the character of the city away from its gritty, urban roots and toward the idyllic suburbia that came into vogue after World War II.

Westborough was built in three phases between 1960 and 1969. As one of South City’s “newest” post-war neighborhoods, its one- and two-story homes are generally larger than those found in older developments, measuring in at between 1,500 and 2,000 square feet. Most have two car garages and small lawns and have been maintained well by their owners. Westborough is well-positioned for car and train commuters, close to two large shopping centers and Tanforan and includes a hidden bonus: a series of walking trails which run through the northern end of the district. Add all of this up and you have a neighborhood where recent sales have fallen in the $1 million to $1.6 million range, putting Westborough at the top of South San Francisco’s real estate market.
