Augrented Insights Report for 846 Prospect Place

846 Prospect Place is a 20-unit, 4-story "new law" tenement building located in Crown Heights, constructed in 1915 and currently owned by Zalmen Biederman. The property has experienced recurring heating issues in 2025, with multiple heat and hot water complaints between April and May 2025, though most were resolved promptly or confirmed as corrected upon inspection.

The Department of Housing Preservation and Development (HPD) issued multiple violations in April 2025 for various maintenance issues including problems with walls, ceilings, ceilings, floors, and unsanitary conditions. A specific pattern of rodent-related problems has emerged, with inspections consistently showing rat activity from March to July 2025, leading to multiple baiting interventions. The building has a concerning history of maintenance issues, particularly related to the heating system, with multiple complaints about heating problems in 2024-2025, including specific violations regarding inadequate heat supply and maintenance of the heating system's access in apartment 8.

There are also several open violations as of October 2023 regarding Boiler Inspection Report filings, various safety-related issues, and structural concerns including a problematic retaining wall noted in 2024. The property has active violations related to energy efficiency reporting requirements, with multiple failures to file required benchmarking reports and external low-pressure inspections since 2020. While there have been some attempts to address building maintenance issues through various permits and inspections, including work on electrical wiring and plumbing systems in 2018, many violations remain unresolved or have required multiple follow-ups for compliance.
