820 Second Avenue is a condominium of 31 tax lots with 26 owners of record, none holding half of its market value. That is from the NYC Department of Finance's 2026/27 assessment roll (BBL 1013367502). Deeds and mortgages for each unit are public in ACRIS, the city's property records system.

820 Second Avenue reported an ENERGY STAR score of 90 for calendar year 2024 in its Local Law 84 benchmarking filing. Under Local Law 33, as amended by Local Law 95 of 2019, a score of 85 or higher earns an A, 70 to 84 a B, 55 to 69 a C and under 55 a D, so 90 earns an A. The Department of Buildings assigns the grade a building posts, so the posted label can differ if a filing was corrected. Its site energy use came to 70.5 kBtu per square foot, less than half the national median of 146.5 for a similar property. Its greenhouse gas emissions were about 942 metric tons of CO2e (5.67 kg per square foot).

At its 2024 energy use, 820 Second Avenue comes to about 785 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,258 tons for 2024 to 2029 (62% of the limit), so it would owe no penalty. From 2030 the limit drops to 442 tons and the same energy use counts as about 567 tons, about 125 tons over, or an estimated $33,000 a year unless the building cuts its emissions. 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. It is not the building's Local Law 97 report, which can count credits and deductions this estimate cannot.

The Department of Buildings issued no permits for new jobs at 820 Second Avenue in the 12 months to October 2026; the last one was first permitted in May 2025.

The newest build-out, on floor 1 and the mezzanine, was first permitted in April 2025 (construction; filed cost estimate $70,000). These are the Department of Buildings' DOB NOW work permits for tax lot 1013367502. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
