What is Local Law 88?

Local Law 88 is a New York City regulation that focuses on energy efficiency in large buildings. It requires buildings over 25,000 square feet to upgrade their lighting systems and install submeters for tenant spaces over 10,000 square feet. The goal is to reduce energy consumption and improve overall building efficiency. Compliance deadlines were phased in, with final deadlines typically in 2025. The law is part of the city's broader efforts to reduce greenhouse gas emissions.

Local Law 88 Lighting Upgrades

Lighting system upgrades are required to improve energy efficiency in buildings by replacing outdated lighting systems with more efficient alternatives. This includes lamps, bulbs, ballasts, and lighting controls such as occupancy sensors and timers.


All non-residential buildings over 25,000 square feet must upgrade their lighting to meet current NYC Energy Conservation Code standards by January 1st, 2025.

Local Law 88 Sub-metering

Tenant sub-metering is required to promote energy awareness and conservation by measuring individual tenant energy usage. Building owners are expected to notify tenants of their monthly usage to promote a reduction of energy usage.



Buildings with tenant spaces larger than 10,000 square feet must install electrical sub-meters for each tenant space by January 1st, 2025.
