1 Hanover Square

1 Hanover Square has about 36,000 square feet of floor area in total, including 36,000 square feet of retail, according to NYC PLUTO 26v2. These are the city's estimates for the whole building, not space that is available.

City records list 1900 as the year built. The building is 3 floors tall.

The tax lot at 1 Hanover Square includes Hanover Bank, an individual landmark designated December 21, 1965 (LP-00042). Changes to a designated landmark, including many storefront, window and signage changes, need a permit from the Landmarks Preservation Commission.

City records list 2 Hanover Square, 95-105 Pearl Street and 60-66 Stone Street on the same tax lot (BBL 1000297502) as 1 Hanover Square. A space listed on Leasemark at any of these addresses shows up on this page.

1 Hanover Square is in ZIP code 10004, according to the city's tax lot records (NYC PLUTO 26v2) and the Department of Finance's assessment roll. The full mailing address is 1 Hanover Square, New York, NY 10004, in the Financial District.

The lot is in the C5-5 zoning district. PLUTO lists a built floor area ratio (FAR) of 3.87 and a maximum commercial FAR of 15 for this lot. It is inside the Stone Street Historic District, so exterior changes go through the Landmarks Preservation Commission.

Leasemark does not have the building's tenant roster, but SEC filings name companies with offices at 1 Hanover Square. One investment manager files 13F holdings reports from the address: Irth Capital Management LP. Private companies do not file with the SEC, so the full list of tenants is longer, and a company can also report a building it owns.

1 Hanover Square reported an ENERGY STAR score of 53 for calendar year 2024 in its Local Law 84 benchmarking filing. Under Local Law 33, as amended by Local Law 95 of 2019, a score of 85 or higher earns an A, 70 to 84 a B, 55 to 69 a C and under 55 a D, so 53 earns a D. The Department of Buildings assigns the grade a building posts, so the posted label can differ if a filing was corrected. Its site energy use came to 66.2 kBtu per square foot, about the same as the national median of 69.5 for a similar property. Its greenhouse gas emissions were about 295 metric tons of CO2e (6.27 kg per square foot).

At its 2024 energy use, 1 Hanover Square comes to about 231 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 403 tons for 2024 to 2029 (57% of the limit), so it would owe no penalty. From 2030 the limit drops to 141 tons and the same energy use counts as about 143 tons, about 2 tons over, or an estimated $500 a year unless the building cuts its emissions. This is an estimate from the owner's 2024 benchmarking filing using the coefficients and per-use limits in the law and the Department of Buildings rule, at $268 per ton over. It is not the building's Local Law 97 report, which can count credits and deductions this estimate cannot.

The Department of Buildings issued no permits for new jobs at 1 Hanover Square in the 12 months to October 2026; the last one was first permitted in June 2025. In the last two years, interior work was permitted on one floor (floor 3 and the mezzanine). The newest build-out, on floor 3 and the mezzanine, was first permitted in June 2025 (structural; filed cost estimate $40,000). These are the Department of Buildings' DOB NOW work permits for tax lot 1000297502. A permit is approval to do the work; it does not say who the work is for or whether it is finished.
