Source: NYC Department of Finance, Storefronts Reported Vacant or Not (Local Law 157), annual filings for 2019 to 2024, pulled 2026-10-08. 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, summed over the condominium's unit lot that filed, 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.
