Questions about this building

Does 949 Willoughby Avenue, Brooklyn have open violations?

Yes. 949 Willoughby Avenue, Brooklyn had 38 open violations on September 26, 2026: 38 from HPD. 12 are Class C, the class HPD treats as immediately hazardous.

Is 949 Willoughby Avenue, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 13 certifications filed against 3 new Class C in the last 180 days. That window ends September 26, 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 949 Willoughby Avenue, Brooklyn?

Since September 28, 2023, certifications were filed on 5 Class C violations, all 5 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 949 Willoughby Avenue, Brooklyn have active DOB violations?

Yes. 51 active DOB violations, most of them for low-pressure boilers. The newest was issued November 14, 2025. 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 949 Willoughby Avenue, Brooklyn marked completed?

Yes. 3 completed HPD emergency repair orders since September 28, 2023, awarded for $4,325 in total. The most recent of the 3, a general construction order, was opened August 4, 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.

Does 949 Willoughby Avenue, Brooklyn have a certificate of occupancy?

Its latest certificate of occupancy is temporary, issued April 27, 2015. 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 949 Willoughby Avenue, Brooklyn?

ENERGY STAR score 48 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.

Is 949 Willoughby Avenue, Brooklyn covered by Local Law 97?

Yes. It is on DOB's Local Law 97 covered buildings list. Covered since 2024 (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.

When was 949 Willoughby Avenue, Brooklyn built?

The city's record gives 1901 as the year 949 Willoughby Avenue, Brooklyn 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 3 floors.

How many apartments does 949 Willoughby Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 45 residential units at 949 Willoughby Avenue, Brooklyn. 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 certificates of occupancy, HPD emergency repair orders, Local Law 84 energy reports, DOB's Local Law 97 covered buildings list and the city's PLUTO tax-lot file. This page is current through September 26, 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 certificates of occupancy, HPD emergency repair orders, Local Law 84 energy 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.
