Bel Air is an affluent residential community in the hills of the Westside of the city of Los Angeles, California. Together with Beverly Hills and Holmby Hills it forms the Platinum Triangle of Los Angeles neighborhoods. Bel Air is situated about 12 miles (19 km) west of downtown Los Angeles and includes some of the foothills of the Santa Monica Mountains. It borders the north side of UCLA along Sunset Boulevard. At the heart of the community sits the Bel Air Country Club and the Hotel Bel Air. The community was founded in 1923 by Alphonzo E. Bell, Sr.
Bel Air is home to numerous Hollywood celebrities and high-profile corporate executives. The Bel Air Association has been operational since 1942, dedicated to preserving the lifestyle and property-values of their residential community. Residences range from relatively modest ranch-style houses, to large mansions. In general, the higher up the mountain, the smaller the building lots, and more modest the houses. Multi-family housing is not permitted and ordinances regarding architectural styles and lot sizes help to preserve the area.
