Classifications & outcomes
The three results of a LL97 review.
Building emissions at or below the assigned tCO₂e cap. No penalty owed. Annual report still required.
Excess emissions × $268/tCO₂e = annual penalty. Owner may pursue Good Faith Effort mitigation if actively decarbonizing.
No annual report filed by May 1. Penalty: $0.50/sq ft of gross floor area. Large buildings: six-figure exposure.
The cost of missing
LL97 penalties compound fast.
LL97 enforcement is largely administrative — DOB runs compliance sweeps based on filing status, not complaint volume. Once you're flagged, penalties apply until the underlying filing or condition is resolved.
Missed filing
$0.50 per sq ft for failure to file the annual report
Compliance failure
$268 per metric ton CO₂e over limit (annually); $15/tCO₂e on rent-regulated pathway
Deadline pattern: Annual report due May 1 covering prior calendar year
What we monitor
How ViolationWatch tracks Local Law 97 for every building in your portfolio.
01
Auto-mapping per BIN
We resolve every building you add to its BIN, BBL, block, and lot — and check whether LL97 applies automatically.
02
Deadline calendar
Annual filing; 5-year compliance periods (2024–2029, 2030–2034, …) is computed and calendared per building. Visible in the dashboard; reminders fire at 60, 30, and 7 days.
03
Filing status
We surface any existing LL97 filings on record, so you know before you start whether the building is current, due, or already in arrears.
04
Routing by role
LL97 reminders go to whoever owns compliance filings at your portfolio — property manager, asset manager, legal counsel, or the super.
05
Related violations
LL97 non-compliance commonly generates downstream DOB violations. When one appears, we correlate it to the underlying law automatically.
