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.
NYC Department of Finance records
The Department of Finance lists 31 WEST 27TH STREET PROPERTY INVESTORS I V, LLC as the owner of record. For tax year 2026/27 the city values 31 West 27th Street at $48.3 million and assesses it at $21.7 million. After phase-ins and exemptions its taxable value is $21.7 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 $2.36 million a year before abatements, roughly $22.06 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.

NYC energy benchmarking (Local Law 84)
31 West 27th Street's 2024 Local Law 84 benchmarking filing got no ENERGY STAR score (too much of the floor area is classed as other uses), 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 88.8 kBtu per square foot, 77% above the national median of 50.2 for a similar property. Its greenhouse gas emissions were about 990 metric tons of CO2e (9.27 kg per square foot).

A permit is approval to do the work; it does not say who the work is for or whether it is finished.
