Questions about this building

Does 150 Lefferts Avenue, Brooklyn have open violations?

Yes. 150 Lefferts Avenue, Brooklyn had 191 open violations on September 27, 2026: 181 from HPD and 10 from OATH/ECB. 96 are Class C, the class HPD treats as immediately hazardous. The oldest open HPD violation has been open 27 years, since February 3, 1999.

Is 150 Lefferts Avenue, Brooklyn getting better or worse?

New violations are coming in faster than certifications are filed. 13 new Class C against 1 certification filed 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 150 Lefferts Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 166 Class C violations, all 166 by the original certify-by date. HPD now marks 1 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.

Is 150 Lefferts Avenue, Brooklyn in HPD's Alternative Enforcement Program?

Yes. In HPD's Alternative Enforcement Program since January 31, 2025. HPD puts a group of buildings with serious, long-running violations into the program each year. While a building is in it, HPD can make repairs itself and charge the cost to the property, and the building stays in until HPD discharges it.

Does 150 Lefferts Avenue, Brooklyn have an OATH hearing coming up?

Yes. 2 hearings scheduled on DOB summonses, the first on January 4, 2027. 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 150 Lefferts Avenue, Brooklyn have active DOB violations?

Yes. 39 active DOB violations, most of them for elevators. 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.

Is 150 Lefferts Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened June 7, 2024. 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 150 Lefferts Avenue, Brooklyn?

Yes. 10 DOB complaints in the 12 months to September 25, 2026. The newest was filed July 4, 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.

Are any HPD emergency repair orders at 150 Lefferts Avenue, Brooklyn marked completed?

Yes. 9 completed HPD emergency repair orders since September 29, 2023, awarded for $30,950 in total. The most recent of the 9, an elevator order, was opened May 13, 2025. 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 is the ENERGY STAR score for 150 Lefferts Avenue, Brooklyn?

ENERGY STAR score 4 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 150 Lefferts Avenue, Brooklyn last file its bedbug report?

On December 2, 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 150 Lefferts Avenue, Brooklyn 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.

When was 150 Lefferts Avenue, Brooklyn built?

The city's record gives 1939 as the year 150 Lefferts Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as an elevator apartment building with 6 floors.

How many apartments does 150 Lefferts Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 53 residential units at 150 Lefferts 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 HPD's Alternative Enforcement Program list, OATH hearing dates, DOB violations, HPD's housing court cases, DOB complaints, 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 HPD's Alternative Enforcement Program list, OATH hearing dates, DOB violations, HPD's housing court cases, DOB complaints, 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.
