Augrented Insights Report for 312 East 91st Street

The 5-story, 15-unit Old Law Tenement at 312 East 91st Street, built in 1910 and currently owned by Denis Sujak, has experienced several notable issues in recent years, particularly regarding sanitation and pest control. Most recently, in March 2025, there were multiple complaints about unsanitary conditions involving dogs, followed by rodent activity confirmations in April 2025. The building has faced persistent pest-related challenges, with documented infestations in 2023 (5 units) and 2024 (1 unit), though the most recent bedbug report for 2023-2024 shows no infested units.

Between 2023 and 2024, the building underwent several inspections revealing various conditions including mold, damp spots, and multiple pest-related issues, though most inspections resulted in no violations being cited. The property has also had significant safety-related concerns, particularly in 2023, when violations were found regarding smoke detectors, carbon monoxide detectors, self-closing doors, and handrails, all of which were certified as corrected by June 2023. Two open violations from 2020 regarding floor drains in the rear and east courtyards remain unresolved.

Historical records show a pattern of rodent activity and sanitation issues, with multiple inspections between 2019 and 2025 confirming problematic conditions. Between 2018-2019, the building faced construction-related violations regarding inadequate guardrails and toeboards on scaffolding, though these were promptly addressed. The building's management has submitted annual bedbug reports and rodent inspections, with the most recent rodent inspections showing ongoing activity despite previous compliance passes in 2019, 2022, and 2023.
