524 5th Street, Brooklyn, NY 11215

The three-story residential building at 524 5th Street in Park Slope, owned by Michael Derian, is a four-story, 8-unit New Law Tenement constructed in 1920. The building has experienced several significant maintenance issues over the past few years, most notably between late 2018 and early 2019 when Unit 3R (3rd story) underwent multiple inspections and received various Housing Maintenance Code violations.

These included problems with window guards, lead-based paint hazards, mold remediation needs, and multiple requirements for repairs and repainting of surfaces in different rooms. The Department of Housing Preservation and Development (HPD) issued both Class C (immediate hazard) and Class B (less severe) violations during this period. More recently, there were two notable health and safety complaints: an asbestos-related complaint in March 2019 (which was reviewed by the Department of Health and Mental Hygiene) and a mold complaint in December 2018.

However, in positive news for prospective tenants, the building's bedbug reports from 2021 to 2025 show no instances of infestation, with all reporting periods (2019-2020 through 2024-2025) indicating zero infested, eradicated, or re-infested units. The most recent violation, recorded in April 2021, related to the requirement to file an annual bedbug report, which appears to have been subsequently complied with given the regular reporting of zero infestations. While the building experienced substantial maintenance issues during 2018-2019, there have been no significant complaints or violations noted in recent years, particularly regarding pest control and safety systems.
