Source: NYC Department of Finance, Storefronts Reported Vacant or Not (Local Law 157), annual filings for 2019 to 2025, pulled 2026-10-16. 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 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.

How to find who owns any NYC building

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 2026-10-16; 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.
