J.E. Brown doesn't care what the SF Rent Board heating requirements are for buildings with controlled heating. Perhaps they're trying to save the owner some money on heating costs, but they're also creating the risk of the owner getting fined by the City Housing Inspector for violating the code.
J.E. Brown provides the heating at a building that I'm a tenant at, and they're constantly adjusting the timer so that it doesn't meet the City's code. I actually overheard a J.E. Brown employee, Al, say to my building manager that the City requires the heat to be turned on for 13 hours a day, be he knows a way to get around that. It's despicable that he's constantly meddling with my right to a heated apartment, and he's been very rude the times that I've talked to him. When I called their main phone number and spoke to a woman that worked for them, she argued with me about what the heating requirements are, even though I was reading exactly what was on stated on the SF Rent Board website. Then she told my building manager that I bullied her.
I've lived in other buildings with controlled heating, and I've never had to fight so hard to get sufficient heating because of J. E. Brown.
