The 2025 filing was due June 1, 2026, so a storefront vacant then may have been leased since. A vacant storefront is not always on the market, and none here is listed on Leasemark unless it shows above.

Local Law 97 emissions limit
At its 2024 energy use, 620 Avenue of the Americas comes to about 3,173 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 5,546 tons for 2024 to 2029 (57% of the limit), so it would owe no penalty. From 2030 the limit drops to 1,843 tons and the same energy use counts as about 1,961 tons, about 118 tons over, or an estimated $32,000 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: Office 517,413 SF; Retail Store 214,200 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.
