Does 104 Sunnyside Avenue, Brooklyn have active DOB violations?

Yes. 5 active DOB violations. The newest was issued January 15, 2014. 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 104 Sunnyside Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened January 22, 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 104 Sunnyside Avenue, Brooklyn?

Yes. 1 DOB complaint, a conversion complaint, in the 12 months to September 25, 2026. It was filed April 18, 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.

Yes. 4 completed HPD emergency repair orders since September 29, 2023, awarded for $14,154 in total. The most recent of the 4, a lead paint order, was opened August 8, 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 104 Sunnyside Avenue, Brooklyn built?

The city's record gives 1910 as the year 104 Sunnyside Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a two-family dwelling with 2 floors.

How many apartments does 104 Sunnyside Avenue, Brooklyn have?

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, HPD's housing court cases, 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 records are the authority on what is open today.

Sources. HPD housing violations and OATH/ECB hearing results, plus DOB violations, HPD's housing court cases, 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.
