Augrented Insights
AI summary · updated June 2026

121 Jamaica Avenue is a 22-unit, 4-story New Law Tenement building located in Cypress Hills and owned by Bqny Properties LLC. The 1917 structure has experienced recurring heat and hot water issues, with multiple complaints filed between March and April 2025, including three at the end of March that resulted in HPD violations, and a pattern of similar complaints dating back to 2022. More recently, in May 2025, several complaints regarding construction work, including work without a permit and construction contrary to stop work orders, were filed and some remain under investigation. The building has also faced safety concerns, with violations issued in January 2024 for defective smoke and carbon monoxide detectors in Apartment 16, and issues identified with fire door self-closing mechanisms.

Historical maintenance records show patterns of rodent activity, particularly notable between 2020-2022, though a rodent inspection in April 2024 resulted in a passing grade. The building has maintained a zero-record of bedbug infestations in the past five reporting periods from 2019 to 2024. Emergency plumbing and other maintenance issues have been documented regularly, suggesting ongoing challenges with building systems. The property’s management has often responded to complaints through inspections and corrections, though there have been instances of access denial during inspections, particularly regarding several 2025 construction-related complaints.
