Local Law 97 of 2019, estimated
Local Law 97 emissions limit
At its 2024 energy use, 333 Dumont Avenue comes to about 893 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,200 tons for 2024 to 2029 (74% of the limit), so it would owe no penalty. From 2030 the limit drops to 341 tons and the same energy use counts as about 569 tons, about 228 tons over, or an estimated $61,000 a year unless the building cuts its emissions.

Estimated from the owner's 2024 Local Law 84 filing, which reports energy by source and floor area by use: Supermarket/Grocery Store 50,408 SF. It applies the coefficients and per-use limits in Department of Buildings rule 1 RCNY 103-14 and Administrative Code 28-320.3.1.1 (as the Department lists them) and the $268 per ton penalty, checked 2026-10-04. It is not the building's Local Law 97 report: that report can count renewable energy credits, solar and storage deductions and, for 2024 and 2025, the law's occupancy group limits where higher, and penalties can be reduced for good faith efforts.
Change these numbers in the Local Law 97 calculator to see what a cut in energy use would do to the penalty.
