How to Reduce Local Law 97 Penalties
Local Law 97 fines are based on how far your building's emissions are over its limit. Heating and cooling are usually the biggest source, so HVAC upgrades are often the fastest way to cut the bill.
Signs Your Building Is at Risk
Oil or old steam heat
Fuel-burning heating is usually the largest emissions source.
Equipment runs 24/7
Poor scheduling wastes energy every night and weekend.
Overheated apartments or offices
Open windows in winter mean you are paying to heat the street.
No recent energy audit
You may not know where the biggest savings are.
How LL97 Penalties Work
Most NYC buildings over 25,000 square feet have a yearly carbon limit based on their use. Emissions over the limit are fined per metric ton of CO2e (the law sets this at $268 per ton). Limits get stricter in 2030, so a building that passes today may not later. Lowering fuel and electricity use — especially for heating — directly lowers the fine.

Frequently Asked Questions
Get answers to common questions about our services
How are Local Law 97 penalties calculated?
The fine is the building's emissions over its limit, in metric tons of CO2e, multiplied by $268 per ton, each year.
Which buildings must follow Local Law 97?
Generally buildings over 25,000 square feet, plus some groups of buildings on one lot over 50,000 square feet. Check the NYC Department of Buildings covered buildings list.
What is the fastest way to lower an LL97 fine?
Usually controls and scheduling fixes, steam system repairs and fan/pump VFDs — they cost less and start saving right away.
Do heat pumps help with Local Law 97?
Yes. Switching heating from gas or oil to efficient electric heat pumps is one of the biggest ways to cut emissions, especially as the grid gets cleaner.
When do Local Law 97 limits get stricter?
The first limits started in 2024 and they tighten significantly in 2030, with further cuts after that.
Can you file our LL97 report?
Official reports are filed by a registered design professional. We handle the HVAC upgrades and provide the equipment data they need.
