Questions about this building

Does 300 Tompkins Avenue, Brooklyn have open violations?

Yes. 300 Tompkins Avenue, Brooklyn had 48 open violations on September 26, 2026: 46 from HPD and 2 from OATH/ECB. 13 are Class C, the class HPD treats as immediately hazardous.

Is 300 Tompkins Avenue, Brooklyn getting better or worse?

Certifications are being filed about as fast as new violations come in. 6 certifications filed and 5 new Class C in the last 180 days, neither far ahead. 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 300 Tompkins Avenue, Brooklyn?

Since September 28, 2023, certifications were filed on 3 Class C violations, all 3 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.

Has DOB received complaints about 300 Tompkins Avenue, Brooklyn?

Yes. 8 DOB complaints in the last 12 months, 3 of them conversion complaints. The newest was filed May 24, 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.

Does 300 Tompkins Avenue, Brooklyn have a certificate of occupancy?

Its latest certificate of occupancy is a final one, issued June 18, 2025. 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.

When was 300 Tompkins Avenue, Brooklyn built?

The city's record gives 1900 as the year 300 Tompkins 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 300 Tompkins Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 7 residential units at 300 Tompkins 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, DOB certificates of occupancy 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 complaints, DOB certificates of occupancy 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.
