The site where Berkeley Patients Group — the city’s largest medical cannabis dispensary — is located is listed as “for sale” on a local real estate agency’s website, raising questions as to whether rumors that federal authorities have targeted the dispensary are in fact true.

A Feb. 8 letter from California NORML Director Dale Gieringer claimed the federal government had recently sent a letter to the Berkeley Patients Group, one of three dispensaries in the city, warning it that its business was violating a federal law that requires 1000 feet between medical cannabis businesses and schools or playgrounds.

The date when the listing first appeared is unclear, but it was online as of Wednesday morning.

Although California law only requires a 600-foot distance between schools and dispensaries, BPG is just around the corner from Ecole Bilingue de Berkeley, a private elementary and middle school located at 1009 Heinz Ave.

According to the school’s spokesperson, Jennifer Monahan, the school is not particularly concerned with the dispensary’s proximity at the moment. In 2010, however, the school did raise some concerns when BPG considered moving to a much closer location, which was ultimately bought by someone else.

The 17,000-square-foot lot at 2747 San Pablo Ave. is listed for $2.5 million on Gordon Commercial Real Estate’s website and includes approved plans to build a five-story building on the site intended for residential and commercial purposes.

Berkeley Patients Group did not return calls for comment on the matter and have not confirmed whether or not they received the letter.

“They’ve been providing a very important service for people who need medical cannabis,” said Berkeley City Councilmember Darryl Moore, who represents the dispensary’s district. “They have been great neighbors and supporters by making donations to local organizations.”

The dispensary has been operating since 2000 and offers services such as acupuncture and massage in addition to medical cannabis.

According to its website, the dispensary has been “working hard to establish a positive relationship with our neighbors, the city, and the police department.” The website encourages patients not to loiter in the area and to “be courteous to those who live and work nearby.” The dispensary also employs security guards to monitor the parking lot.

Moore said he was not aware of the dispensary’s plans but hopes it will remain in the area if it does end up moving out of its current location.

“They’ve been absolutely marvelous — I would really hate to see them go,” Moore said.
