Police Raid $4.4 Million San Francisco Squatter Mansion—Arresting Woman and Rescuing 7 Dogs

The woman allegedly at the center of a squatting dispute in San Francisco’s luxury Sea Cliff community was arrested on Friday during a raid of the property and following a monthslong investigation into her claims on the home.

Diana Peng, 42, was charged with fraud, driving without a license, narcotics possession, improper care of animals, and being a felon in possession of a firearm and ammunition. Police also removed seven dogs from the home and put them in the care of a local shelter.

Peng and her alleged accomplice, Brandon Aadee, are in the midst of a civil lawsuit brought by San Francisco City Attorney David Chiu. Chiu accused the pair of illegally obtaining the $4.4 million property through forged, fraudulently notarized deeds, intending to sell it.

According to Chiu’s complaint, Peng and Aadee took over the 3,000-square-foot Tudor-style home at 250 32nd Ave. in 2025 by claiming that the previous owner had transferred the deed to Aadee. Peng and Aadee transferred the property title back and forth between them eight times, and at least five of those were forged, including the initial deed from the legitimate owner, Wei Wang, which includes a forged notary signature.

Wang and her husband, Xiangdong Guo, purchased the property in 2013 for $2.41 million. But the pair moved abroad around 2019, and the property fell into disrepair and appeared to be abandoned.

It also racked up more than $340,000 in unpaid property taxes, which prevented a sale of the property.

This past October, however, the San Francisco Board of Supervisors approved a resolution to pay off the property taxes, paving the way for the home to be put up for auction later this year.

Neighbors in the wealthy enclave, where both Sharon Stone and Twitter founder Jack Dorsey have homes, said they spent much of the past year on edge, watching people come and go from the property at all hours.

"I'm probably in touch with one city official or another at least six times every day," neighbor Whitney Lynn told ABC 7. "We really have been asking for help, and it feels like people finally heard us.

Most recently, in August, a neighbor called 311 to complain that the property was “being used as a group home.”

“The home was abandoned for over 5 years, and squatters moved in May 2025 using burglary tools. Over the past couple of days, a new group of about a dozen squatters moved in," the complaint read.

Nearly a dozen complaints were also filed with the Department of Building Inspection, the most recent on Oct. 13. That complaint stated that unpermitted plumbing and irrigation work had been taking place in the backyard.

Neighbors told the San Francisco Chronicle that Friday’s raid lasted about four hours and that police removed several boxes and bags of documents. Police went in with guns drawn and came out with Peng, and seven dogs were removed from the property and taken to a local shelter. Police also towed Peng's Porsche.

Deb Campbell, the public information officer with San Francisco Animal Care and Control, tells Realtor.com® the two adult pit bulls and five puppies are “doing well in our care.” She otherwise couldn’t comment on the animals' condition because of the ongoing investigation.

“We appreciate SFPD’s work to pursue accountability and keep our neighborhoods safe,” Jen Kwart, the communications director for the city attorney’s office, tells Realtor.com. "As our civil case moves forward, we look forward to continuing to work closely with SFPD to ensure the courts understand that Defendants are effectively trying to steal a house and sell it to make millions in profit.”

Both Peng and Aadee have long criminal records. In 2008, she was convicted of perjury and sentenced to 90 days in jail and three years’ probation. Four years later, she pleaded guilty to identity theft and burglary and served seven months in prison. And then in 2015, she was sentenced to an additional two years in jail for forgery of a driver’s license and using another person's identification.

In 2009, Aadee was convicted of defrauding FEMA out of thousands of dollars and ordered to pay $48,000 in restitution. He also has convictions for credit card fraud and passing bad checks.

Following Friday’s raid, Peng was booked and is being held without bail at the San Francisco County Jail.
