Augrented Insights
AI summary · updated June 2026

936 Herkimer Street is a three-story, three-unit residential building in Bedford-Stuyvesant owned by Jean Idfresne, constructed in 2005. The building has experienced several maintenance issues over the past five years, including multiple heat and hot water complaints in 2018-2019, water supply problems in 2019, and a ceiling maintenance issue in 2020, though inspections by the Department of Housing Preservation and Development (HPD) found no violations in these cases. More concerning are the current open violations from 2024 related to bedbug reporting requirements, along with multiple active Environmental Control Board (ECB) violations from 2020-2021 regarding failure to comply with inspection and correction orders. These violations pertain to occupancy concerns, egress maintenance, and safety equipment requirements, with penalties totaling $27,375.

The building has a documented history of compliance issues following a 2018 investigation that resulted in summonses for illegal conversion and egress problems, leading to multiple subsequent ECB violations for non-compliance with correction orders. Despite these challenges, the building has passed all recent rodent inspections (2020-2025) and maintained a current bedbug treatment record showing successful eradication of infestations in all units. A work permit application from November 2019 remains in process as of the latest available data. The property has experienced recurring issues with building system reliability and maintenance compliance, as evidenced by the pattern of complaints and violations, though many historical issues have been resolved or closed.
