We go down to the boiler room so you don't have to. LL97 carbon fine exposure quantified. Retrofit economics modeled. Compliance path mapped. For the buildings, owners, and advisors who can't afford to guess.
Local Law 97 went live in January 2024. It applies to buildings over 25,000 square feet — about 50,000 properties in New York City. The law sets annual carbon emissions caps by building type, and fines owners $268 for every metric ton of CO2e they run over.
The caps get significantly stricter in 2030. A building that's borderline today may be deeply non-compliant in six years. Owners who haven't modeled their Period 2 exposure are flying blind.
Most engineering firms will sell you a compliance plan. Most attorneys will bill you to read the DOB rules. Very few people will sit down with you and say: here is your exact fine, here is where it's coming from, and here is the cheapest path to zero. That's what we do.
// Calculated from LL84 benchmarking data + NYC DOB caps. Actual fine = $268 × annual tCO2e overage.
We're not a general-purpose MEP firm. We specialize in one problem: figuring out exactly what LL97 will cost you, and what to do about it.
We pull your buildings' LL84 benchmarking data and run every property against the LL97 cap tables — Period 1 and Period 2. You get a ranked list of exposure, fuel type, energy grade, and owner contact data in one sheet.
For buildings where the fine is material, we model the economics of the compliance path — heat pump conversion, fuel switching, LED + envelope — using current EIA fuel prices and real NYC contractor benchmarks.
A written memo — not a 200-page engineering study — that tells your asset manager or lender exactly where you stand, what the options are, and what a PE-stamped plan will cost to execute. Good for board decks, loan packages, and refi due diligence.
A list of addresses, BBLs, or a PLUTO export. We'll clean it. Takes you ten minutes.
We cross-reference your buildings against LL84, LL33, PLUTO, ACRIS, HPD, and live EIA fuel prices. Automated where possible, verified by hand.
You get a ranked exposure report. Every building scored. Hot ones flagged. We tell you which three need immediate attention and why.
For priority buildings: a written compliance strategy with options, cost ranges, and financing guidance. Lender-ready, plain English.
Every data source we use is public. The advantage isn't access — it's knowing which datasets to combine, how to clean the joins, and what the numbers actually mean for your building.
You own 3 to 30 buildings, probably through a mix of LLCs. Nobody on your team has read LL97 in full. You need to know which two are about to cost you real money and what it takes to fix them.
Your clients ask about LL97 exposure during transactions. You need a fast, credible screen that you can put in front of a buyer or an underwriter without starting a three-month engineering study.
You manage 50+ buildings for multiple owners. You need a way to triage the portfolio — rank by fine exposure, flag the critical ones, and give each owner a clear picture before the DOB starts sending notices.
We charge for the work, not the clock. Every engagement is scoped upfront.
Full LL97 fine screen for up to 25 buildings. Delivered as a ranked spreadsheet with data sources cited.
Deep-dive on a single building: fuel cost baseline, heat pump ROI, retrofit cost estimate, payback at current prices, C-PACE screening.
Full economics model plus a written compliance strategy brief — three pathways, costs, timeline, financing options. Designed for loan packages and board presentations.
A 30-minute call is free. We'll tell you upfront if the screen is worth doing.
Schedule a callThe fastest way to start is an email. Tell us the portfolio size, what you already know about LL97 exposure, and what decision you're trying to make. We'll scope it from there.
If you already have a BBL list or a PLUTO export, email it over and we'll do a free preliminary screen before we even talk.
