The estimate is the taxable value times the class rate. It leaves out abatements, payment-in-lieu-of-taxes agreements and charges, so the actual bill can differ.

Local Law 97 emissions limit

At its 2024 energy use, 817 Broadway comes to about 487 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,329 tons for 2024 to 2029 (37% of the limit), so it would owe no penalty. From 2030 the limit drops to 521 tons and the same energy use counts as about 307 tons, still under the limit.

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.

This is an estimate from the owner's 2024 benchmarking filing using the coefficients and per-use limits in the law and the Department of Buildings rule, at $268 per ton over.
