Prudential California Realty became the first company to operate as a member of the new Berkshire Hathaway HomeServices network, and was renamed Berkshire Hathaway HomeServices California Properties, the company said.

To celebrate the transition, the business held an open house at one of its listings in the tony town of Del Mar. The 12,000 square foot property with an ocean view is listed at $7.5 million. It includes five bedrooms and six and a half baths.

Berkshire Hathaway HomeSevices California Properties has about 3,200 sales associates in 62 offices in Southern California and the Central Coast.

It is one of the top five brokerages in the nation, the company said. Last year its agents closed nearly $11 billion in sales and more than 14,000 transactions.

The real estate brokerage network is owned and operated by HSF Affiliates LLC, which is a joint venture that is owned mainly by HomeServices of America, an affiliate of Berkshire Hathaway Inc., the holding company founded by Warren Buffett.
