Questions about this building

Does 521 West 42 Street, Manhattan have open violations?

Yes. 521 West 42 Street, Manhattan had 57 open violations on September 27, 2026: 10 from OATH/ECB and 47 from HPD. 13 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 4 years, since January 18, 2022.

Is 521 West 42 Street, Manhattan getting better or worse?

Certifications are being filed faster than new violations come in. 12 certifications filed against 2 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 521 West 42 Street, Manhattan?

Since September 29, 2023, certifications were filed on 18 Class C violations, all 18 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 521 West 42 Street, Manhattan have an OATH hearing coming up?

Yes. 5 hearings scheduled on DOB summonses, the first on October 15, 2026. DOB summonses are heard at OATH, the city's hearings office, and OATH can move a hearing to a later date. When nobody shows up, the summons is decided by default, the costliest way one ends.

Does 521 West 42 Street, Manhattan have active DOB violations?

Yes. 3 active DOB violations. The newest was issued June 23, 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.

Is 521 West 42 Street, Manhattan in housing court?

Yes. 1 open housing court case, opened February 6, 2026. 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 521 West 42 Street, Manhattan marked completed?

Yes. 1 completed HPD emergency repair order since September 29, 2023: a general construction order, opened July 14, 2025, awarded for $770. 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 did the latest facade report find at 521 West 42 Street, Manhattan?

Rated SWARMP in the latest facade report, filed July 11, 2024 (inspection cycle 9). 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.

Does 521 West 42 Street, Manhattan have a certificate of occupancy?

Its latest certificate of occupancy is temporary, issued February 14, 2018. A certificate of occupancy says how a building may be used and occupied. A temporary one lets people move in while work finishes and has to be renewed until DOB issues the final one. DOB's records here start in July 2012, so an older certificate may not show.

What is the ENERGY STAR score for 521 West 42 Street, Manhattan?

ENERGY STAR score 72 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 did 521 West 42 Street, Manhattan last file its bedbug report?

On December 15, 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 521 West 42 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 521 West 42 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 521 West 42 Street, Manhattan built?

The city's record gives 2005 as the year 521 West 42 Street, Manhattan was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a condominium with 19 floors.

How many apartments does 521 West 42 Street, Manhattan have?

The Department of City Planning's PLUTO tax-lot file lists 72 residential units at 521 West 42 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 OATH hearing dates, DOB violations, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB certificates of occupancy, HPD emergency repair orders, Local Law 84 energy 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 OATH hearing dates, DOB violations, HPD's housing court cases, the Rent Guidelines Board's stabilized-building lists, DOB facade filings, DOB certificates of occupancy, HPD emergency repair orders, Local Law 84 energy 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.
