Is 100 Lefferts Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 14 open Class C, with 1 certification filed and 3 new Class C in the last 180 days, too few to call a direction. 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 100 Lefferts Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 11 Class C violations, all 11 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 100 Lefferts Avenue, Brooklyn have active DOB violations?

Yes. 6 active DOB violations, most of them for construction. The newest was issued June 20, 2023. 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.

Has DOB received complaints about 100 Lefferts Avenue, Brooklyn?

Yes. 2 DOB complaints in the 12 months to September 25, 2026. The newest was filed January 1, 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 100 Lefferts Avenue, Brooklyn marked completed?

Yes. 2 completed HPD emergency repair orders since September 29, 2023, awarded for $1,572 in total. The most recent of the 2, a general construction order, was opened October 10, 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.

When was the boiler at 100 Lefferts Avenue, Brooklyn last inspected?

On June 23, 2026. 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 100 Lefferts Avenue, Brooklyn last file its bedbug report?

On December 24, 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 100 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.

Is 100 Lefferts Avenue, Brooklyn 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 100 Lefferts Avenue, Brooklyn built?

The city's record gives 1929 as the year 100 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 100 Lefferts Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 60 residential units at 100 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 DOB violations, DOB complaints, 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 DOB violations, DOB complaints, 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.
