Mulholland Estates is a guard gated community in the Beverly Hills Post Office area. Although properties in the estates have a 90210 zip code, much of the land is located inside the Sherman Oaks district. The community's main entrance is located at Beverly Glen Boulevard and Mulholland Drive, next to Fossil Ridge Park, and it overlooks the San Fernando Valley.

The community was developed by Kenneth Kai Chang, Alfred E Mann and Robert A Sandler. Chang had initially planned to build a "luxury restaurant" on Mulholland Drive as well as "100 condominiums and 29 single-family homes", but decided to build 95 luxury homes instead. Fred Sands acted as the original brokerage when it was under construction in 1988. It was described as "one of the Valley's biggest and most brash housing developments" by The Los Angeles Times

The homes range in size from 5,000 square feet up to over 16,000 square feet. The lot sizes are large as well, between 1/3 of an acre up to 1.5 acres. Residents enjoy three lighted tennis courts, a playground, and a clubhouse with racquetball courts and a dance studio. Homeowner Dues also cover the cost of common area landscape maintenance and 24/7 security.
