The NYC Department of Finance's 2026/27 assessment roll lists 667 MADISON AVENUE DE LLC as the owner of record of 667 Madison Avenue (BBL 1013750049). Big buildings are usually held through a company set up for that one property, so the name on the roll can differ from the landlord's brand or the managing agent.

Leasemark does not have the building's tenant roster, but SEC filings name companies with offices at 667 Madison Avenue. 2 public companies report the address as their principal executive office: MEDALLION FINANCIAL CORP (MFIN) and INTERNET SCIENCES INC.. 3 investment managers and funds file 13F holdings reports from the address: Corvex Management LP; Egerton Capital (US), LP; and MARK ASSET MANAGEMENT LP. Private companies do not file with the SEC, so the full list of tenants is longer, and a company can also report a building it owns.

667 Madison Avenue reported an ENERGY STAR score of 83 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 83 earns a B. 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 46.4 kBtu per square foot, 41% below the national median of 78.6 for a similar property. Its greenhouse gas emissions were about 1,084 metric tons of CO2e (4.49 kg per square foot).

At its 2024 energy use, 667 Madison Avenue comes to about 781 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 1,836 tons for 2024 to 2029 (43% of the limit), so it would owe no penalty. From 2030 the limit drops to 644 tons and the same energy use counts as about 478 tons, still under the limit. 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.
