829 Nostrand Avenue, Brooklyn, NY 11225

The 4-story, 10-unit building at 829 Nostrand Avenue in Crown Heights, currently owned by Clari Gilbert and built in 1912, has experienced a notable pattern of maintenance issues over recent years, particularly related to heating and water systems. Between December 2024 and 2025, there have been multiple complaints regarding heat and hot water (affecting the entire building), water leaks, mold, and air quality concerns involving chemical vapors, with several inspections unable to be completed due to lack of access. The building's history reveals recurring problems with pest infestations, as evidenced by multiple violations and service requests between 2020 and 2024, including significant issues in apartment 4B involving both mice and roaches, along with mold and water leak problems in late 2024.

Two separate pest-related violations were issued in October 2024, though HPD did conduct inspections and issue violations that required correction. The property also has outstanding compliance issues with external low pressure inspections, with an active violation from April 2023 and a previous violation from September 2024 that was dismissed. The building's maintenance record shows some completed repairs, such as addressing unsafe electrical wiring conditions and alterations to a metal mesh wall in the first-floor public hall as of January 2025.

Despite these ongoing issues, recent rodent inspections in 2024 and 2025 have passed, indicating some improvement in pest control measures. The building's heating system has been a particular area of concern, with multiple emergency complaints about lack of heat affecting the entire building, though the Department of Housing Preservation and Development was often unable to gain access for inspections. The property has maintained a zero infestation rate for bed bugs in annual reporting periods, suggesting effective control of this particular pest type. The most recent 311 service requests as of April 2025 for mold and slow water leaks also faced access issues for inspection.
