Local law 87 Extensions and Deferrals

The Department of Buildings announced in September of 2014 the availability of Deferrals and Extensions for the filing of LL87: Energy Audits and Retro-commissioning.


As a reminder, LL87 mandates that most NYC buildings over 50,000 square feet undergo periodic energy audit and retro-commissioning measures and that owners submit an Energy Efficiency Report once every 10 years. Failure to file these reports will result in a DOB violation and $3000 civil penalty.
