My brother, a friend of ours, and myself just moved into a huge apartment on the upper west side. The apartment itself is 61 ft long (don't know width off hand, will post it later). There are three bedrooms, a dining room, a full kitchen, and another room. The landlord made a stink about having three people on the lease (as we were getting the lease from a friend of ours and he wanted to jack the rent up as high as he could, so he wanted 'new' tenants, so he was trying to get rid of us. He had his office not take our phone calls and claimed to have 'lost' our credit applications.) But anyway, so only my brother and my friend's name are on the lease, yet I am living there with them.
As far as I can tell, under the current laws, this is perfectly legal. There is more than enough space, so we're not overcrowding, and I'm immediate family to one of the lease-holders.
Let me know what you guys think.
