Augrented Insights Report for 939 St Marks Avenue

The 16-unit, 4-story tenement building at 939 St. Marks Avenue in Crown Heights, owned by Nosson Lang, has experienced ongoing maintenance and pest control challenges in recent years. The property has documented rat activity as recently as June 2025, with multiple rodent-related complaints and inspections showing continued infestations requiring attention.

The building has faced various maintenance issues in 2025, including problems with flooring, walls, and cabinets, resulting in multiple Housing Maintenance Code violations that required HPD inspections. Specific issues included the presence of mold, water leaks, and surface damage in Apartment 1C, with violations cited between August and October 2024. Historical records show recurring rodent problems, with rodent inspections in 2010, 2016, 2017, 2018, 2024, and most recently in 2025 indicating persistent infestation issues.

The building has also experienced infrastructure challenges, including a water leak emergency in early 2025 and a flooring problem that required HPD inspection. Notably, there are currently two active violations: one from 2023 regarding failure to file 2020 external low-pressure inspection records, and a most recent rat activity violation from June 2025. While no bedbug infestations have been reported in recent years, the building's maintenance history suggests ongoing attention is needed to address persistent pest control and infrastructure issues.
