Source: NYC Department of Finance, Storefronts Reported Vacant or Not (Local Law 157), annual filings for 2019 to 2024, pulled 2026-10-02. Owners of buildings with ground- or second-floor storefronts register each one every year with its status on December 31; counts are by tax lot, as the owners filed them. The 2024 filing was due June 3, 2025, 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.

Source: NYC Department of Finance, Property Valuation and Assessment Data (2026/27 roll; owner names as the roll records them, which cuts some long names short), pulled 2026-10-02; tax rate from the Department of Finance tax rates page, checked 2026-09-28. 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.
NYC energy benchmarking (Local Law 84)
Energy use and emissions
45 West 25th Street's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score (a campus of several buildings cannot get a score), and Local Law 33 letter grades come from that score, so the filing does not yield an A to D grade. Its site energy use came to 37.9 kBtu per square foot, 41% below the national median of 64.5 for a similar property. Its greenhouse gas emissions were about 475 metric tons of CO2e (3.02 kg per square foot). The filing covers 2 tax lots together, so these figures are for the whole property.

A job counts once, when its first permit is issued; renewals are not new work. A build-out groups jobs on the same floors first permitted within 120 days of each other. Costs are the estimates filed with the jobs. Jobs filed before DOB NOW (in the older BIS system) are not counted. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
