The New York roommate agreement is a contract that details the rental obligations of a group of people living together and defines their rights and responsibilities within the household. A standard lease doesn’t specify how roommates are expected to behave, nor does it describe the unique financial commitments of each occupant. For this reason, an internal agreement between the roommates should be drafted. With this contract, the occupants are able to divide amongst themselves the cost of rent, utility fees, and other maintenance expenses. The agreement may also incorporate regulations concerning loud music, overnight guests, pets, and the sharing of personal property.
