A county judge ruled earlier this month that the man, who allegedly "will regularly yell and shout to himself and others" and "spends most of his time in or around the center," must now stay at least 250 feet away.
"There is an order and we hope that it solves the problem," said Livery general manager Nancy Casale. She declined to comment further.
Court records show that Livery lawyer Jennifer Freedman filed reports indicating the retail location has suffered damages because of the man's behavior. Tenants felt unsafe, and customers had been more or less scared away, she wrote.

But a combination of few available bed spaces and the fact that over 90 percent of schizophrenic patients go off their medication within a year, makes mentally ill transients a troublesome county social issue - even for upscale bedroom communities like Danville.
Currently, about 25 percent of the single adult homeless population suffers from some form of severe and persistent mental illness, according to the most recent National Coalition for the Homeless report.

The defendant didn't attend the most recent court hearing and could not be reached for comment. Court documents filed in September 2007 show a request for a restraining order. But to date it is unclear whether the man is even aware of the lawsuit.
Should the behavior persist, he risks a fine of $1,000 and jail time.
