Local Law 88
Local Law 88 of 2009 requires NYC buildings over 25,000 square feet to upgrade lighting in non-residential spaces to current energy code and to install sub-meters for large commercial tenants. The deadline was January 1, 2025; non-compliance triggers DOB violations and blocks Certificate of Occupancy amendments.
Frequently asked questions
Does LL88 apply to residential corridors and lobbies?
Lighting in common areas of residential buildings counts as non-residential lighting under the code and must comply. In-unit residential lighting is out of scope.
What does sub-metering require?
Each commercial tenant over 5,000 square feet needs a dedicated electrical sub-meter, and the building must provide monthly consumption data to the tenant. Most pre-2010 buildings have only a single utility meter and need a licensed electrician to install the sub-metering panel.
Who files the TR8?
A NYS-licensed Professional Engineer or Registered Architect who is a Registered Design Professional with DOB. Lighting contractors and managing agents cannot sign the filing themselves.
What if we missed the January 2025 deadline?
There is no cure period and no automatic civil penalty, but the building accrues a DOB violation that blocks new permit issuance until resolved. The board should commission a lighting audit and TR8 filing immediately rather than wait for an enforcement trigger.
