Is this going to end up being the proverbial apartment from hell?

I may have a legal problem brewing. It involves an apartment in a building that is otherwise condos. I have little knowledge of real-estate or condo law, and need some advice.

We rented our unit from the building owner 2 months ago. All the other units in the building are condos and have been sold to other residents here. The owner told me he ran the condo association. This week, I got a gas bill for the entire building. It was addressed to Occupant, Unit S1. I have no gas service in my unit (#1), but gas heat and hot water are supplied by the owner or so my lease states. The bill was $625 for about 3 month’s service.

As I was standing in the hall looking at the bill, the lady that lives upstairs from me came in and asked if it was from the gas company. When I said it was, she said it was meant for her. She went on to explain that the condo owners are in a legal dispute with the building owner (my landlord) because he had not payed the gas bills for more than a year. They took legal action to set up their own condo association when they received notice from the gas company of pending shut off this spring.

Where does this leave me? Presumably, part of my rent should be split out each month and added to the condo association fees to cover gas, maintenance of the common areas, and a rainy-day fund for repairs should the water heater go kaput or whatever. But if the building owner and condo association head (or former head) was pocketing association fees, he will certainly continue to do so with rents I pay to him. I’m guessing I should just pay him as usual and let the courts sort it out, but I would appreciate any advice anyone knowledgeable in condo law could give.
