Is 40 Thayer Street, Manhattan getting better or worse?

Open violations are sitting, with little movement either way. 23 open Class C, with 0 certifications filed and 1 new Class C in the last 180 days, too few to call a direction. That window ends September 27, 2026. It compares certifications filed with new Class C violations, and it describes what happened, not what anyone intends.

Does 40 Thayer Street, Manhattan have active DOB violations?

Yes. 3 active DOB violations. The newest was issued April 14, 2021. 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 40 Thayer Street, Manhattan?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed September 26, 2025. 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.

Are any HPD emergency repair orders at 40 Thayer Street, Manhattan marked completed?

Yes. 2 completed HPD emergency repair orders since September 29, 2023, awarded for $2,556 in total. The most recent of the 2, a general construction order, was opened December 8, 2025. HPD orders an emergency repair when a hazardous condition cited in a violation, or in another agency's emergency order, is not corrected, and does the work itself or through a contractor. The amounts are what the orders were awarded for, not a bill: this page does not show what was charged to the property or whether it was paid. Orders for lab tests, such as dust-wipe and asbestos samples, are not counted.

What is the ENERGY STAR score for 40 Thayer Street, Manhattan?

ENERGY STAR score 54 for 2023, against a median of 66 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.

When was the boiler at 40 Thayer Street, Manhattan last inspected?

On August 14, 2026. DOB requires a boiler in a building with 6 or more apartments to be inspected once every calendar year, with the report filed within 14 days of the inspection. Low-pressure boilers in residential buildings with 5 or fewer apartments are exempt.

When did 40 Thayer Street, Manhattan last file its bedbug report?

On May 12, 2026, for the year to October 31, 2025. HPD asks the owner of every building with 3 or more apartments for this report once a year, covering November 1 to October 31, including buildings that had no bedbugs.

Is 40 Thayer Street, Manhattan covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered from 2026 as a rent-regulated building (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 40 Thayer Street, 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 40 Thayer Street, Manhattan built?

The city's record gives 1927 as the year 40 Thayer Street, 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 40 Thayer Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 72 residential units at 40 Thayer Street, 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, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. This page is current through September 27, 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, HPD emergency repair orders, Local Law 84 energy reports, DOB boiler inspection reports, HPD's annual bedbug 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.
