AI summary · updated June 2026

The three-story, four-unit tenement building at 40 Christopher Avenue in Brownsville, owned by Charlene Mclean, has experienced several significant maintenance issues in recent years. Most notably, in early 2025, there were multiple complaints regarding door-related problems, with one set of complaints resulting in violations that required correction by the property owner, while others could not be properly inspected due to access issues. The building also experienced considerable heat and hot water system problems in January 2025, with multiple complaints filed across several days, though some were duplicates of others.

The building has several open violations from a December 2024 inspection of apartment 2B, including issues with mouse infestation, water leaks, and various repair needs affecting the kitchen and other areas. There are also building-wide concerns about fire safety and egress compliance, with active Environmental Control Board (ECB) violations from 2021 related to fire escape obstructions and failure to comply with previous orders, along with an open Department of Buildings (DOB) violation for failing to certify correction of an immediately hazardous ECB violation.

The property has a history of construction-related complaints, including some regarding illegal conversions and blocked egress pathways in 2020, though most were closed without finding violations. Despite these various issues, the building has maintained a bedbug-free record since 2019, and passed its last rodent inspection in 2016. The property has had multiple inspections over the years, with varying degrees of access issues and compliance outcomes, indicating ongoing challenges with maintenance and repair responsiveness.
