Is 20-15 Cornaga Avenue, Queens getting better or worse?

Certifications are being filed faster than new violations come in. 20 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 20-15 Cornaga Avenue, Queens?

Since September 29, 2023, certifications were filed on 26 Class C violations: 25 by the original certify-by date, 1 after it. HPD now marks 2 of them Invalid Certification. 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 20-15 Cornaga Avenue, Queens have active DOB violations?

Yes. 10 active DOB violations, most of them for boiler filings under Local Law 62/91. The newest was issued May 4, 1998. 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.

Are any HPD emergency repair orders at 20-15 Cornaga Avenue, Queens marked completed?

Yes. 4 completed HPD emergency repair orders since September 29, 2023, awarded for $5,550 in total. The most recent of the 4, a general construction order, was opened July 24, 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 20-15 Cornaga Avenue, Queens last inspected?

It has 2 boilers, both inspected in 2025, the latest on December 26. 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 20-15 Cornaga Avenue, Queens last file its bedbug report?

Its 2 buildings had all filed by March 20, 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 20-15 Cornaga Avenue, Queens 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 20-15 Cornaga Avenue, Queens built?

The city's record gives 1931 as the year 20-15 Cornaga Avenue, Queens 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 4 floors.

How many apartments does 20-15 Cornaga Avenue, Queens have?

The Department of City Planning's PLUTO tax-lot file lists 30 residential units at 20-15 Cornaga Avenue, Queens. 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, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug reports 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, the Rent Guidelines Board's stabilized-building lists, HPD emergency repair orders, DOB boiler inspection reports, HPD's annual bedbug reports 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.
