(a) Where a tenant requests permission from the owner to install a washing machine, dryer or dishwasher, whether permanently installed or portable, and the owner consents, the owner may collect surcharges, without notification to or approval by the DHCR in an amount specified in an operational bulletin to be issued by the DHCR pursuant to section 2527.11(b) of this Title. The surcharges authorized by this section shall not be part of the legal regulated rent.

1. (1) Where a prior installation by a tenant of a washing machine, dryer or dishwasher comes to the attention of the owner and the owner consents to the continued use of the washing machine, dryer or dishwasher, the surcharges provided for in this section shall only be available prospectively.
2. (2) Under no circumstances shall servicing or replacement of such washing machine, dryer or dishwasher become a service required to be provided by the owner pursuant to this Code.
3. (3) Where there is in effect a prior practice of charging for installation of a tenant-owned washing machine, dryer or dishwasher, the owner may continue the charge, which may also continue to be included in the legal regulated rent, if such was the prior practice.

(b)
