Augrented Insights Report for 840 Jefferson Avenue

840 Jefferson Avenue is an 8-unit, 4-story New Law Tenement building located in Bedford-Stuyvesant, Brooklyn, and owned by Simpleton Resource Fund Xvii. The 1910 structure has experienced recurring maintenance issues in recent years, with several documented complaints in 2024 relating to unsanitary conditions and pest problems that HPD was unable to inspect, and earlier issues in 2022 involving water leaks and mold that were investigated without any violations being found.

Of particular concern are the multiple active violations regarding external low-pressure inspection failures from 2018-2023, with the most recent being issued in September 2024, indicating possible safety equipment non-compliance. The building has a documented history of rodent activity, with inspection results showing "Rat Activity" in 2019 and 2022, though recent inspections in 2024 and 2025 have passed.

The property has maintained a consistent record of pest control reporting for bedbugs, with no reported infestations or eradications in the past seven years from 2018-2025, suggesting effective management of this particular issue. While the building's housing maintenance code complaints have been addressed and closed in a timely manner, the inability of HPD to gain access for inspections in multiple cases during 2024 raises potential concerns about access to the property for regulatory inspections. The pattern of annual low-pressure inspection violations (active since at least 2019) is notable, though these violations have not yet been resolved as of the most recent data available.
