My question involves landlord-tenant law in the State of: Philadelphia
I moved to Philadelphia a bit over a year ago. Someone from my place of employment contacted me beforehand looking for a roommate and I agreed. He found the place and sent pictures but withheld measurements and some other crucial details meanwhile indicating how urgent it was that we apply and sign before we lose the place. After I moved the room was WAY smaller than he had led me to believe, basically fitting only a full bed and a small chest of drawers; I had to turn sideways to walk around from one side of the bed to the other. I learned later on that the room was actually used as an office space by the previous tenant. I lived with it for the first year and got accustomed to the place, primarily not wanting to deal with moving hassle. A month after our lease renewed, my girlfriend moved up to Philly to start grad school. I found someone to take over my lease and found a new place. However, just before the new tenant signed the lease, he pulled out as he ran into some financial problems. I've had no luck finding a new tenant since given how small and expensive the room is for what it's worth.
I came across sources that state that an individual bedroom in Pennsylvania must be 80 square feet and have a source of centralized heating (no space heaters) to qualify as a bedroom. My 'room' is a far cry from these requirements. Would these be adequate grounds for me to exit the lease, and perhaps get some money back?
