Masjid Abubaker Siddiq's history dates to 1985, when a group of Afghan immigrants organized prayer services in a leased storefront on Mission Boulevard. In 1988, a 3/4 acre empty lot was purchased at 29414 Mission Boulevard as the intended location for Hayward's first purpose-built mosque, with an additional 2.75 acres purchased at the same site in 1992.
In November 1995, plans were submitted for a 10,000 square foot Islamic center, and ground was broken in June 1996. An occupancy permit was officially issued in February 2001, and a grand opening ceremony was held in June. The two-story mosque is stucco-faced, with bays of windows set in bands of Islamic tiles. A small dome sits above the entrance portico. The building has two prayer halls, two washrooms, office space, second-floor classroom space, a kitchen, and multipurpose meeting area. More than 300 worshipers can be accommodated in the prayer halls, with nearly 700 in the whole facility. As of 2011 funds were being raised to construct a minaret.
