(b) A building's classification as a hotel will not be retained or continued where the DHCR determines that 51 percent of the permanent tenants are not receiving maid and linen service, except that all tenants receiving such services shall be entitled to receive the services for the duration of their occupancy. Where an owner is providing maid and linen service to 51 percent of the permanent tenants and the owner wishes to maintain the building's classification as a hotel, the owner shall be afforded 90 days to restore all four hotel services described above, without any additional rent increase for such services, to all of the building's permanent tenants, except that those tenants whose housing accommodations were rented to them as apartment (not hotel) housing accommodations shall have the option of rejecting restoration of hotel services and be subject to the RSL, pursuant to the provisions of this Code applicable to apartment buildings, until they vacate, at which time the owner shall be required to restore hotel services to the housing accommodations.
(c) Notwithstanding the provisions of subdivision (a) of this section, single-room occupancy facilities such as single-room occupancy hotels or rooming houses, as defined in the MDL, shall not be subject to reclassification pursuant to this section. However, such housing accommodations shall be included in the definition of hotel as set forth in section 2520.6(b) of this Title for all other purposes of this Code, except that the four minimum services enumerated in such section shall not be required to be provided unless such services were provided on the applicable base dates pursuant to section 2520.6(r)(4) of this Title.
