The New York City Department of Buildings recently announced new updated guidelines regarding filing deadlines for Local Law 97:
- Deadlines have been extended until August 29 (from June 30) to file for an extension
- With an extension, a new filing deadline is December 31
- Buildings can now qualify for Good Faith Efforts if they submit a plan to comply with Local Law 88 (lighting upgrades and submetering)
Why This Matters
-
More time, more options: these deadline changes give building owners critical flexibility to avoid penalties and stay on track toward compliance.
-
The city is investing in support programs: the Mayor’s Office is expanding programs like NYC Accelerator, which provides help with technical planning, retrofit assistance, and funding opportunities.
