Local Law 88 requires property owners to upgrade their lighting systems and install tenant sub-meters. It is part of a package of laws known as the Greener Greater Buildings Plan, which were enacted in December 2009 to improve the energy and water efficiency of New York City’s largest existing buildings.
You have until January 1, 2025 to sub-meter your commercial tenant spaces and upgrade the lighting throughout the building in both landlord and tenant areas.
Property owners and co-op and condo associations are ultimately responsible for complying with the law. However, many of these parties will delegate the reporting to their property manager or a tenant submetering provider.
