300 Park Avenue

300 Park Avenue has about 645,000 square feet of floor area in total, including 613,000 square feet of office and 32,000 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 1954 as the year built, with a major alteration recorded in 1997. The building is 25 floors tall.

City records list 47-59 East 49th Street and 54 East 50th Street on the same tax lot (BBL 1012850036) as 300 Park Avenue. A space listed on Leasemark at any of these addresses shows up on this page.

City records give two ZIP codes for this tax lot: 10017 in NYC PLUTO 26v2 and 10022 on the Department of Finance's assessment roll. Some large New York buildings have a ZIP code of their own beside the area's, so check with the building's management which one it uses before you rely on either.

The lot is in the C5-3 zoning district. PLUTO lists a built floor area ratio (FAR) of 18.96 and a maximum commercial FAR of 15 for this lot.

The NYC Department of Finance's 2026/27 assessment roll lists 300 PARK AVENUE INC as the owner of record of 300 Park Avenue (BBL 1012850036). Deeds and mortgages for the lot are public in ACRIS, the city's property records system.

Leasemark does not have the building's tenant roster, but SEC filings name companies with offices at 300 Park Avenue. One public company reports the address as its principal executive office: COLGATE PALMOLIVE CO (CL). 5 investment managers and funds file 13F holdings reports from the address, including Davern Capital Partners, LP; GOLDENTREE ASSET MANAGEMENT LP; and LDR Capital Management LLC. 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.

300 Park Avenue reported an ENERGY STAR score of 71 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 71 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 60 kBtu per square foot, 26% below the national median of 81.6 for a similar property. Its greenhouse gas emissions were about 4,384 metric tons of CO2e (5.64 kg per square foot).

At its 2024 energy use, 300 Park Avenue comes to about 3,159 metric tons of CO2e a year under Local Law 97's coefficients, against a limit of 5,996 tons for 2024 to 2029 (53% of the limit), so it would owe no penalty. From 2030 the limit drops to 2,210 tons and the same energy use counts as about 2,002 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 10 jobs at 300 Park Avenue. In the last two years, interior work was permitted on 6 floors (floors 3, 4, 16, 17, 24 and 25). The newest build-out, on floor 24, was first permitted in October 2026 (construction; filed cost estimate $9,000). A sidewalk shed permit here is active until November 3, 2026. These are the Department of Buildings' DOB NOW work permits for tax lot 1012850036. A permit is approval to do the work; it does not say who the work is for or whether it is finished.

The city's property tax records for BBL 1012850036 show the actual bill.

Owners registered 6 storefronts at 300 Park Avenue for December 31, 2025, the newest annual filing the city has published, and 1 of them stood vacant that day. At least one storefront here has been reported vacant at the end of every year since 2020. 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.
