Augrented Insights
AI summary · updated June 2026

807 Washington Avenue, a 6-story, 11-unit residential building constructed in 2018 in Crown Heights, has experienced some notable public health challenges since its inception. The most significant concerns were between August and November 2020, when the property was the subject of multiple Department of Health and Mental Hygiene (DOHMH) complaints regarding rodent activity, including at least one instance of rat sightings and conditions attracting rodents. These incidents resulted in health code violations that required follow-up inspections, as documented through the city's 311 service request system. More recently, during the bedbug reporting period from November 2023 to October 2024, the building showed no evidence of pest infestations, with zero reported infested or re-infested dwelling units, and no units requiring eradication. The current owner of the building is David Katz, and while the 2020 rodent issues represent a significant historical event for the property, the absence of any pest complaints in the past three years suggests improvement in building conditions.

What's driving this score

These are the three data points that most influenced this building's score — ranked by how much weight the model placed on each one.

Number of apartments

The number of residential units affects how the model interprets complaint and violation totals — more units means more potential sources.

Neighborhood location

The model uses precise location as a proxy for neighborhood-level risk patterns — some blocks have systematically higher violation rates.

City enforcement actions (past 7 years)

Environmental Control Board violations — formal city enforcement actions with associated fines.
