Questions about this building

Does 11 Seaman Avenue, Manhattan have open violations?

Yes. 11 Seaman Avenue, Manhattan had 25 open violations on September 26, 2026: 25 from HPD. 11 are Class C, the class HPD treats as immediately hazardous.

Is 11 Seaman Avenue, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 11 open Class C, with 1 certification filed and 7 new Class C in the last 180 days, too few to call a direction. That window ends September 26, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

When were certifications filed on Class C violations at 11 Seaman Avenue, Manhattan?

Since September 28, 2023, certifications were filed on 13 Class C violations: 10 by the original certify-by date, 3 after it. A certification is the filing, dated when it was made, not HPD's acceptance of it. It is compared with the original certify-by date on the notice. A granted postponement moves that date and the city's data keeps only the first, so a certification counted after it may still have met a postponed date.

Does 11 Seaman Avenue, Manhattan have active DOB violations?

Yes. 13 active DOB violations, most of them for not benchmarking energy use. The newest was issued August 3, 2024. The Department of Buildings writes these separately from HPD's housing violations, for things like boilers, elevators, facades, construction and energy filings. Each one stays active until DOB resolves or dismisses it.

Has DOB received complaints about 11 Seaman Avenue, Manhattan?

Yes. 45 DOB complaints in the last 12 months. The newest was filed September 13, 2026. Anyone can complain to DOB about a building or the work going on in it, and DOB then inspects and decides whether there is a violation. A conversion complaint says an apartment may have been added or changed without approval. It is a complaint, not a finding.

What is the ENERGY STAR score for 11 Seaman Avenue, Manhattan?

ENERGY STAR score 15 for 2024, against a median of 67 for Multifamily Housing that year. Buildings over 25,000 square feet report their energy use to the city every year under Local Law 84. The ENERGY STAR score runs from 1 to 100 and compares a building with similar ones nationwide; 50 is the national median. The score is the one the city publishes, and this page never estimates a Local Law 97 emissions penalty. A lot that reported several properties in one year is not scored here.

Is 11 Seaman Avenue, Manhattan covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered under Article 321, the path for certain affordable housing and houses of worship (DOB's list, March 1, 2026). Local Law 97 sets greenhouse gas limits for most New York City buildings over 25,000 square feet, and DOB's covered buildings list says which path each building is on. The list reflects DOB's records, which owners can ask DOB to correct. This page never estimates a penalty or says whether a building complies.

Is 11 Seaman Avenue, Manhattan rent stabilized?

The building has rent-stabilized apartments on its 2024 registration. That comes from the Rent Guidelines Board's list of buildings with at least one stabilized apartment registered that year. Buildings that registered late are left off, and a 421-a or J-51 building can leave stabilization when its tax benefit ends. A particular apartment's status is for NYS HCR to say.

When was 11 Seaman Avenue, Manhattan built?

The city's record gives 1925 as the year 11 Seaman Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a walk-up apartment building with 5 floors.

How many apartments does 11 Seaman Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 72 residential units at 11 Seaman Avenue, Manhattan. The count is for the whole tax lot.

Where do these numbers come from?

From New York City's own data: HPD housing violations and OATH/ECB hearing results, read whole rather than sampled. It also draws on DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, Local Law 84 energy reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. This page is current through September 26, 2026. The city's data changes daily, so a violation certified after that can still show as open here; the city's own page for this building is linked above.

Sources. HPD housing violations and OATH/ECB hearing results, plus DOB violations, DOB complaints, the Rent Guidelines Board's stabilized-building lists, Local Law 84 energy reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. Counts cover HPD Class B and C violations from the last 3 years that HPD still shows open, and OATH/ECB summonses from the same 3 years that the city still shows active. The city's own pages can show more, never fewer.
