Questions about this building

Does 3815 Nautilus Avenue, Brooklyn have open violations?

Yes. 3815 Nautilus Avenue, Brooklyn had 16 open violations on September 26, 2026: 16 from HPD. 14 are Class C, the class HPD treats as immediately hazardous.

Is 3815 Nautilus Avenue, Brooklyn getting better or worse?

Open violations are sitting, with little movement either way. 14 open Class C, with nothing filed or new in the last 180 days. 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 3815 Nautilus Avenue, Brooklyn?

Since September 28, 2023, certifications were filed on 14 Class C violations, all 14 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 3815 Nautilus Avenue, Brooklyn have active DOB violations?

Yes. 1 active DOB violation, issued August 16, 1993. 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 3815 Nautilus Avenue, Brooklyn in housing court?

Yes. 1 open housing court case, opened December 12, 2023. 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.

Are any HPD emergency repair orders at 3815 Nautilus Avenue, Brooklyn marked completed?

Yes. 1 completed HPD emergency repair order since September 28, 2023: a general construction order, opened June 11, 2025, awarded for $577. 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 3815 Nautilus Avenue, Brooklyn built?

The city's record gives 1901 as the year 3815 Nautilus Avenue, Brooklyn was built, in the Department of City Planning's PLUTO tax-lot file. The same file classes it as a three-family dwelling.

How many apartments does 3815 Nautilus Avenue, Brooklyn have?

The Department of City Planning's PLUTO tax-lot file lists 3 residential units at 3815 Nautilus 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, HPD's housing court cases, HPD emergency repair orders 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 violations, HPD's housing court cases, 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.
