About this home

The Updegraff Estate, East Gate Bel Air, CA. Offers to be reviewed on October 6, 2023. One of the last remaining great view promontories left in Bel Air. Located on prestigious Chalon Road, this 1.5 acre property is available for the first time in 65 years. The home has hosted some of the most notable stars, politicians and prominent California families for more than six decades and is now for sale for the first time. Over the years, many of the renowned estates have been either subdivided, demolished or torn down, and only a few properties still remain in the hands of these original families. One of the greatest views to hit the market in years.
