One Seaport Plaza is a condominium of 36 tax lots with 3 owners of record, none holding half of its market value. That is from the NYC Department of Finance's 2026/27 assessment roll (BBL 1000747501). Deeds and mortgages for each unit are public in ACRIS, the city's property records system.

One Seaport Plaza reported an ENERGY STAR score of 79 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 79 earns a B. 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 55.2 kBtu per square foot, 36% below the national median of 86.4 for a similar property. Its greenhouse gas emissions were about 5,708 metric tons of CO2e (5.69 kg per square foot).

At its 2024 energy use, One Seaport Plaza comes to about 4,147 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 7,685 tons for 2024 to 2029 (54% of the limit), so it would owe no penalty. From 2030 the limit drops to 2,703 tons and the same energy use counts as about 2,363 tons, still under the limit. 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.

In the 12 months to October 2026, the Department of Buildings issued first permits for 21 jobs at One Seaport Plaza. In the last two years, interior work was permitted on 13 floors (floors 1, 4, 5, 9, 10, 12, 19, 20, 28 to 31 and 34, the cellar and the mezzanine). The newest build-out, on floor 9, was first permitted in July 2026 (construction, mechanical, plumbing, sprinklers; filed cost estimate $876,000). These are the Department of Buildings' DOB NOW work permits for tax lot 1000747501. A permit is approval to do the work; it does not say who the work is for or whether it is finished.

The Department of Finance's 2026/27 assessment roll lists a taxable value of $96.4 million for One Seaport Plaza (the sum of its 36 condominium tax lots). At the Class 4 rate of 10.848% (tax year 2025/26, the latest rate the Department of Finance lists), that is about $10.5 million a year, roughly $14.05 per square foot of floor area, before abatements such as ICAP. The city's property tax records for BBL 1000747501 show the actual bill.

For tax year 2026/27, the NYC Department of Finance puts the market value of One Seaport Plaza at $218.9 million ($52.7 million of it land) and its assessed value at $98.5 million, the 45% of market value the city assesses for Class 4 property.

Owners registered 7 storefronts at One Seaport Plaza for December 31, 2025, the newest annual filing the city has published, and 3 of them stood vacant that day. At least one storefront here has been reported vacant at the end of every year since 2023. These are the owners' filings with the Department of Finance under Local Law 157, so a storefront vacant on December 31, 2025 may have been leased since. Owners and brokers can list a storefront on Leasemark for free.

No space at 199 Water Street is listed on Leasemark right now. Owners and brokers can list space here for free, and tenants can post a requirement to be matched when space opens up.
