A landlord and tenant may enter into a contract for the provision of any housing service which was not a part of the original terms of the tenancy. A valid additional services contract must be written, and must describe each additional service, specify the period of time for which the additional service will be provided, and the monthly charge for the service. Termination of the tenancy shall also terminate the additional services contract. Any monies paid pursuant to an additional services contract shall not be considered rent for any purpose under this chapter. Neither the refusal of a tenant to enter into an additional services contract, nor the breach of such contract shall be a ground for termination of the tenancy. (Added by Ord. No. 156,597, Eff. 5/20/82, Oper. 5/15/82.)
