Is 564 Williams Avenue, Brooklyn getting better or worse?

Certifications are being filed faster than new violations come in. 12 certifications filed against 1 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 564 Williams Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 19 Class C violations: 17 by the original certify-by date, 2 after it. HPD now marks 2 of them False 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.

Has DOB received complaints about 564 Williams Avenue, Brooklyn?

Yes. 1 DOB complaint in the 12 months to September 25, 2026. It was filed May 27, 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 564 Williams Avenue, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 29, 2023: a general construction order, opened September 3, 2025, awarded for $385. 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 564 Williams Avenue, Brooklyn built?

The city's record gives 1930 as the year 564 Williams 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 2 floors.

How many apartments does 564 Williams Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 4 residential units at 564 Williams 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 complaints, HPD emergency repair orders 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 complaints, HPD emergency repair orders 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.
