The longtime home of late Sen. Dianne Feinstein and her late husband, financier Richard Blum, in a stretch of San Francisco's Pacific Heights neighborhood known as "Billionaire's Row" has a new owner.

The three-story, 1917 Italianate mansion at 2460 Lyon St. sits on the famed Lyon Street steps, at the foot of Vallejo street. Among its distinguishing features are meticulously manicured gardens, stunning views of the Bay and proximity to San Francisco's national park, the Presidio.

The 9,500-square-foot property traded hands on June 24 for $19 million, public records show. It served as Feinstein's and Blum's home since 2006, when the couple purchased it for just over $16 million. Feinstein died in September 2023 at age 90, and Blum died in 2022.

The price tag for the property's recent sale places its price-per-square-foot value at $2,000. It's not clear what the value of the Lyon Street mansion was expected to be, but according to reports in 2023, it was previously valued at roughly $21 million.

The identity of its new owner is unknown, but signs point to a high-net worth buyer with ties to New York. The property was purchased with a limited liability company formed in that state this month, public records show.

The home was paid for using "all cash," according to Charlie McCabe of San Francisco Capital Advisors, who viewed the sale documents. McCabe was not directly involved in the deal, but represented Feinstein and Blum in multiple past commercial transactions.

Public records link the entity that was used to purchase the couple's former home to New York resident Nicole Maultasch. The Chronicle attempted to contact Maultasch, but could neither confirm nor rule her out as a buyer.

The mansion represented one of the more significant assets among Feinstein and Blum's real estate holdings, which included vacation homes like the 36-acre Bear Paw Ranch in Aspen, Colo., and a seven-bedroom Lake Tahoe compound, as well as homes in Washington D.C., and on the Hawaiian island of Kauai.

The Aspen Ranch sold in 2023 for $25.2 million, which, according to reporting by the Wall Street Journal, was several millions dollars below asking price. The Lake Tahoe home sold in 2021, reportedly for $36 million.

Blum's vast business empire included investments in the real estate, energy, tech and education sectors. He was also a philanthropist and UC Berkeley benefactor.

As Feinstein's health declined shortly before her death in 2023, the two factions of her family - with her daughter Katherine Feinstein on one side and Blum's three daughters on the other - became embroiled in legal conflicts over Blum's trust and the former senator's desire to sell her Marin County home. That property, located at Stinson Beach, was eventually sold in late 2023 for $9.1 million.

The Lyon Street mansion appears to have been inherited by Katherine Feinstein - the former San Francisco judge was the sole signature on the property's sale last week, records show. Katherine Feinstein could not immediately be reached by the Chronicle.
