If a building manager ceases to perform services as a building manager and, with the agreement of the landlord, remains in the apartment unit he or she occupied while a building manager, the landlord, at his or her option, may adjust the base rent of the apartment unit upward to a level not exceeding that which could have been imposed during the period when such tenant was acting as building manager but for the fact of such tenant's status as building manager. The landlord may also impose any capital expenditure surcharge and utility expense surcharge in amounts equal to those which have been validly imposed upon an apartment building which were not imposed on such tenant because of such tenant's status as building manager.
