4240 Byron Avenue, Bronx, NY 10466

4240 Byron Avenue is a 3-story, 7-unit residential building constructed in 1928, currently owned by Millicent Thomas. The property has experienced several significant maintenance and safety issues in recent months, most notably a cluster of violations in May-June 2025 involving unsanitary conditions with pests, mold, water leaks, and various interior damages such as ceiling problems and window frame issues. These complaints have generally resulted in violations being issued, with specific details available through HPD's online resources.

The building's most serious current concerns relate to Apartment 1B, where inspections in June 2024 identified multiple open violations including lead paint hazards, carbon monoxide detector problems, pest infestation, and various repair needs affecting safety and habitability. The property also has an outstanding Department of Buildings violation from November 2019 regarding an unfiled annual boiler inspection report. Despite these issues, there have been some positive signs regarding pest control, with bedbug reports showing no infestation cases in recent years (2022-2023 reporting period) and a successful rodent compliance inspection in January 2024, though there were some issues noted in late 2023 when bait was applied due to an initial failed inspection.

The building's maintenance history shows a pattern of addressing (or not addressing) various repairs and violations over time, with some conditions resulting in emergency responses from HPD. While some violations have been closed following inspections, many remain open, particularly those concerning safety systems like smoke and carbon monoxide detectors. The property's age and classification as a "New Law Tenement" suggest it is subject to specific regulatory requirements concerning maintenance and lead paint hazards, which appear to be areas of ongoing concern based on the 2024 violation notices.
