NYC filing cutoff
The clock is ticking.
Every year of delay costs more.
NYC's LL97 enforcement ramps up through 2030. Buildings that act now avoid compounding penalties — and the engineering backlog that comes later.
2024
Phase 1 Begins
$268/ton penalty for emissions above your building's carbon cap. Thousands of NYC buildings already over the limit.
May 1
Annual Deadline
Compliance reports due every May 1st. Late or missing filings result in additional DOB violations on top of penalties.
2026
Enforcement Ramp
NYC DOB begins issuing formal violations and escalating enforcement actions against non-compliant properties.
2030
Phase 2 — Stricter Caps
Carbon limits tighten significantly. Penalties can exceed $500/ton. Buildings that ignored Phase 1 face compounded liability.
Built on authoritative data
Common LL97 questions,
answered clearly
New to Local Law 97? Here are the questions we hear most from building owners and engineers.
What is Local Law 97?
LL97 is NYC's landmark climate law capping carbon emissions for buildings over 25,000 sq ft. Buildings that exceed their emissions limit pay $268 per excess metric ton of CO₂e per year.
Is my building covered?
Most NYC buildings over 25,000 sq ft are covered. Run a free scan with your address and we'll check the official NYC covered buildings list instantly — no account needed.
How is my penalty calculated?
Your building's annual carbon limit is set by its occupancy type and gross square footage. Emissions above that limit are multiplied by $268/ton. ComplyDesk pulls your LL84 benchmarking data to calculate this exactly.
What is the May 1 filing deadline?
Every covered building must submit an annual LL97 compliance report to the NYC DOB by May 1st. Missing this deadline triggers additional violations on top of any existing penalties.
What does a PE/RA firm do for LL97?
A licensed Professional Engineer or Registered Architect assesses your building's actual emissions, recommends retrofit strategies, stamps your Good Faith Effort documents, and submits to BEAM on your behalf.
