4112 4th Avenue, Brooklyn, NY 11232

4112 4th Avenue is a 57-unit, 5-story New Law Tenement building located in Sunset Park and managed by 4112 4th Ave Realty LLC. The building, constructed in 1928, has experienced recurring heat and hot water issues throughout 2025, with multiple complaints and emergency situations reported between April and June, including instances affecting the entire building and individual apartments. These heating system problems appear to be persistent, as evidenced by numerous 311 complaints promptly followed by HPD inspections, which generally confirmed resolution of the issues.

The property has a notable history of maintenance and compliance challenges, particularly in the areas of plumbing and electrical systems. In late 2024, multiple violations were documented in Apartment 3L, including issues with sink waste connections, leaky faucets, and several other maintenance concerns. The building's electrical systems have been a significant area of concern, with multiple Department of Buildings violations between 2020-2021 related to unapproved and unsafe electrical equipment, defective circuits, and work done without proper permits.

Additionally, there are outstanding energy efficiency violations from 2023-2024 regarding the failure to file benchmarking reports and display energy efficiency scores, indicating potential ongoing issues with building energy management. The building's history also includes documented rodent activity, with inspections between 2024 and 2021 consistently showing evidence of rat presence, though there were some instances of bait application suggesting attempts to address the problem. However, recent bedbug reports from late 2023 show zero infestations, which is a positive indicator of current pest management. The property has experienced periodic issues with building-wide systems, as demonstrated by the pattern of heat/hot water complaints and emergency situations, suggesting that while many individual complaints are resolved, some systemic issues persist.
