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.
NYC Department of Finance records
The Department of Finance lists GRUNBERG 928 LLC as the owner of record. For tax year 2026/27 the city values 928 Broadway at $24.5 million and assesses it at $11 million. After phase-ins and exemptions its taxable value is $11 million; at the Class 4 rate of 10.848% (tax year 2025/26, the latest rate the Department of Finance lists) that comes to about $1.19 million a year before abatements, roughly $15.64 per square foot of floor area. Commercial leases here often pass a tenant's share of tax increases over a base year through as additional rent.

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.

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.
