Questions about this building

Does 723 St Nicholas Avenue, Manhattan have open violations?

Yes. 723 St Nicholas Avenue, Manhattan had 38 open violations on October 10, 2026: 36 from HPD and 2 from OATH/ECB. 12 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 9 years, since April 18, 2017.

Is 723 St Nicholas Avenue, Manhattan getting better or worse?

Certifications are being filed faster than new violations come in. 23 certifications filed against 11 new Class C in the last 180 days. That window ends October 10, 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 723 St Nicholas Avenue, Manhattan?

Since October 12, 2023, certifications were filed on 28 Class C violations, all 28 by the original certify-by date. 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 723 St Nicholas Avenue, Manhattan have active DOB violations?

Yes. 8 active DOB violations. The newest was issued May 16, 2019. 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 723 St Nicholas Avenue, Manhattan been in housing court?

Yes. 11 housing court cases here since 2007. HPD takes buildings to housing court to get violations fixed and heat and hot water restored, and it joins tenants' own repair cases, called tenant actions. A case stays open until the court closes it.

Has DOB received complaints about 723 St Nicholas Avenue, Manhattan?

Yes. 3 DOB complaints in the 12 months to September 25, 2026. The newest was filed July 19, 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 did the latest facade report find at 723 St Nicholas Avenue, Manhattan?

Rated SWARMP in the latest facade report, filed September 16, 2020 (inspection cycle 9). Reports in earlier inspection cycles rated it Safe in 2009 and 2014. SWARMP means safe with a repair and maintenance program. Buildings taller than six stories must have their exterior walls inspected once in every inspection cycle under the city's Facade Inspection Safety Program (every five years under DOB's current rule), and each inspection report is filed with DOB as Safe, SWARMP (safe with a repair and maintenance program) or Unsafe. No Report Filed means DOB has no report for that cycle. The rating is from the latest filing and does not describe the facade today; DOB's page for the building shows anything filed since.

What is the ENERGY STAR score for 723 St Nicholas Avenue, Manhattan?

ENERGY STAR score 53 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.

When was the boiler at 723 St Nicholas Avenue, Manhattan last inspected?

On August 10, 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 723 St Nicholas Avenue, Manhattan last file its bedbug report?

On December 4, 2025, 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 723 St Nicholas 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 723 St Nicholas 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 723 St Nicholas Avenue, Manhattan built?

The city's record gives 1907 as the year 723 St Nicholas Avenue, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator building with 6 floors.

How many apartments does 723 St Nicholas Avenue, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 40 residential units at 723 St Nicholas 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 OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB NOW work permits, 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 October 10, 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 OATH/ECB summonses from DOB and FDNY, DOB violations, HPD's housing court cases, DOB complaints, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB NOW work permits, 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.
