Does 720 East 91 Street, Brooklyn have active DOB violations?
Yes. 9 active DOB violations. The newest was issued August 22, 2019. 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 720 East 91 Street, Brooklyn?
Yes. 1 DOB complaint in the last 12 months, a conversion complaint. It was filed February 17, 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 720 East 91 Street, Brooklyn marked completed?
Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened September 19, 2024, awarded for $795. 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.

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.
