Questions about this building

Is 735 West 172 Street, Manhattan getting better or worse?

Certifications are being filed faster than new violations come in. 75 certifications filed against 34 new Class C in the last 180 days. That window ends September 27, 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 735 West 172 Street, Manhattan?

Since September 29, 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.

Is 735 West 172 Street, Manhattan in housing court?

Yes. 1 open housing court case, opened November 12, 2025. 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.

Are any HPD emergency repair orders at 735 West 172 Street, Manhattan marked completed?

Yes. 7 completed HPD emergency repair orders since September 29, 2023, awarded for $5,135 in total. The most recent of the 7, a general construction order, was opened May 13, 2026. 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.

When was the boiler at 735 West 172 Street, Manhattan last inspected?

On September 1, 2025. 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 735 West 172 Street, Manhattan last file its bedbug report?

On December 26, 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 735 West 172 Street, 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 735 West 172 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 735 West 172 Street, Manhattan built?

The city's record gives 1920 as the year 735 West 172 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 735 West 172 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 56 residential units at 735 West 172 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 HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, 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 HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, 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.
