The plaque, added recently, features his name, dates of birth and death, and the epitaph 'Much loved – Friend –', a clear nod to his iconic sitcom.
Perry was 54 when he died, with an autopsy revealing the cause as the acute effects of ketamine, alongside contributing factors like drowning and coronary artery disease.
Following a seven-month investigation, five individuals were federally charged in connection with his death.
Dr Salvador Plasencia, who sold ketamine to Perry, was sentenced to 30 months in prison, while another doctor, Mark Chavez, received eight months of home detention; three others await sentencing.
