Broadmoor is a census-designated place (CDP) in an unincorporated area of San Mateo County, California, United States.

[2] According to the United States Census Bureau, the CDP has a total area of 0.432 square miles, all of it land.

[20][3] The racial makeup of the CDP was 1,206 (27.3%) White, 77 (6.4%) Black or African American, 43 (1.0%) American Indian and Alaska Native, 2,084 (47.2%) Asian, 38 (0.9%) Native Hawaiian and Other Pacific Islander, 466 (10.6%) Some Other Race, and 497 (11.3%) two or more races.

[21] Among the residents who were not Hispanic or Latino, 1,060 were White, 65 were Black or African American, 14 were American Indian and Alaska Native, 2,061 were Asian, 34 were Native Hawaiians or other Pacific Islanders, 25 were Some Other Race, and 170 were of two or more races.

The farms that had long graced the area started to give way to suburban housing developments from the 1940s onwards.

[citation needed] The residents of Broadmoor, rallying around their police protection district and their sense of identity as a separate community, have been mostly successful in fighting off annexation by Daly City, despite losing slices of their community's territory, including its police headquarters, in the many piecemeal annexations which over the years saw Daly City gradually encircle Broadmoor in its entirety.

[citation needed] Daly City's attempts to annex the enclave and Broadmoor residents' resistance to those efforts have led to strained relations between the two entities at times.

[27] A special property tax assessment funds the Broadmoor Police Department, which was founded in 1948 after residents grew concerned of long response times from the San Mateo County Sheriff's Department—most of whose deputies are based in the southern end of the county.

In 2007 State Senator Leland Yee (California's Eighth District) authored legislation sponsored by the Broadmoor Police Department to recognize Broadmoor as a municipal or city police department.

[citation needed] As of 2021, an investigation of retirement fraud and misuse of public funds by former top employees of the District is ongoing.

[28][29][30] The former police chief, Michael Connolly, was sentenced to probation for conflict-of-interest charges.

The Colma Fire Protection District also provides 24 hr paramedic (ALS) coverage 365 days a year.

In the California State Legislature, Broadmoor is in the 11th Senate District, represented by Democrat Scott Wiener, and in the 19th Assembly District, represented by Democrat Catherine Stefani.
