Free LL97 baseline + intro to a NYC LL97 consultant.
NYC Local Law 97 caps carbon emissions for buildings 25k+ sqft. Fines started 2025. We identify large buildings, estimate current emissions vs. the cap (free), and refer you to a partner LL97 consultant for the binding compliance plan (retrofit roadmap, energy audit, alternative compliance path).

How it works
1
Building size check
Properties 25,000+ gross sqft are subject to LL 97. We identify your building from the properties table (PLUTO area data) and flag if you're in scope.
2
Emissions estimate
Based on your property class, square footage, fuel mix (electric / gas / steam), and recent energy bills, we estimate your current carbon intensity vs. the LL 97 cap for your use category.
3
Cap-violation risk
LL 97 caps tighten in 2024-2029, then again in 2030-2034. We project your gap so you know whether you're in fine territory now, later, or never.
4
Consultant handoff
If you need action, we route to partner consultants (energy engineers, retrofit contractors, alternative compliance path specialists). They build the plan — we just flag and match.
What's included
No charge from RegWatch. The compliance plan engagement is between you and the consultant.
FAQ
Does my building actually qualify?
LL 97 applies to most buildings 25,000+ sqft in NYC, with specific exclusions (certain city-owned, rent-regulated, affordable housing under Article 321). We run the exact qualifying rule from your property data.
What's the fine for non-compliance?
$268 per metric ton of CO₂ over the cap, per year. For a typical 50k sqft residential building, that can be $50-200k/year if you're significantly over cap.
How expensive is compliance?
Ranges widely. Efficiency lighting + controls: $2-10/sqft. Envelope upgrades: $10-50/sqft. Electrification (heat pumps): $30-80/sqft. ACCA-based energy audit: $5-15k. Alternative compliance path (RECs + offsets): depends on gap.
What about alternative compliance?
RECs (Renewable Energy Credits), GHG offsets, and specific program participation (RGGI, Clean Heat) count toward compliance. Not a full substitute for efficiency upgrades, but useful while you plan larger retrofits.
When are the first fines assessed?
Reporting deadline was May 1, 2025 for 2024 emissions. DOB is actively reviewing reports and issuing OATH violations on non-compliant buildings now. Don't wait.
