Why it matters
The Department of Buildings began issuing the first Local Law 97 penalty notices on May 1, 2026 at $268 per metric ton of CO2-equivalent above a building’s cap, assessed every year the building is over. Roughly 93% of covered private buildings filed their 2024 emissions reports, and enforcement data shows a meaningful share already over cap. Annual reports are due May 1 with a grace period to June 30; a $60 extension filed through the BEAM portal by June 30, 2026 moved the deadline to August 29, 2026. Late filing runs up to $0.50 per square foot per month and false statements carry fines up to $500,000. The law covers most buildings over 25,000 square feet, and the caps tighten again in 2030.
A buyer’s question is no longer “will this building have to comply.” It is “what did this building file, is it over cap, and who is paying for it.” All three have documentary answers, and none of them require you to guess at a number.
What it changes
Ask management for three things: the filed 2024 and 2025 reports, any penalty notice received, and the board’s funded compliance plan with its financing source. Everything else is hallway talk.
A tax lot can hold several buildings and compliance can turn on the individual building identification number. Confirm which BIN the unit sits in before repeating a figure.
$268 per metric ton recurs annually while the building is over cap. Describing it as a one-time hit understates it, and the buyer’s attorney will do the multiplication.
Affordable, rent-regulated and certain other building categories follow different compliance paths. Do not apply the market-rate path to a building that is not on it.
Report what is documented and decline to forecast. “The board budgeted $X and financed it with a $Y line of credit” is a fact. “It should only be about forty dollars a month” is exposure.

The email to managing agents
I represent the owner of Unit X and expect Local Law 97 questions from buyers. Could you send me: (1) the building’s filed 2024 and 2025 LL97 emissions reports, (2) any penalty or violation notice the building has received under LL97, and (3) the board’s current compliance plan, including what has been budgeted and how it is being financed? Please also confirm the building identification number for this address. I will share these documents as received rather than characterizing them.
Next steps
- Add the three-document request to your co-op and condo intake sheet.
- Write the BIN on the listing sheet, not just the block and lot.
- Send technical questions to an energy consultant or engineer and say in writing that you did.
- Disclose any known penalty notice or assessment in writing rather than verbally.
