324 21st Street, Brooklyn, NY 11215

324 21st Street is a 4-unit, 4-story residential building located in Sunset Park and owned by Katerina Moutzouroulia. Built in 1931 as an Old Law Tenement, the building has experienced several significant maintenance issues, particularly in recent years. Between January and April 2025, multiple complaints were filed regarding building conditions, including problems with the heating system, water leaks, plumbing issues, and defective intercom systems, though inspectors were frequently unable to gain access to complete their evaluations.

The building underwent an inspection in October 2024 that revealed several Class B and C violations, including problems with hot water temperature, smoke detector functionality, fire retardant plaster in public areas, roof leaks, and encroachments on safety equipment. Of particular note, there were emergency complaints regarding heat and water issues in January 2025, and violations related to water leakage have persisted as non-emergency complaints since then. The building has a documented history of rodent activity, with multiple bait applications recorded between January and April 2019. Earlier maintenance issues from 2019-2020 included building-wide heat problems.

Despite these numerous complaints and violations, most were closed without resolution due to inspectors being unable to access the apartments for proper evaluation. For example, multiple complaints regarding the intercom system, water leaks, and heating issues were closed with no inspection results. While some violations have been marked as closed, including those related to door safety features, others remain open as of the most recent inspection. The building's maintenance history suggests ongoing challenges with basic infrastructure systems, though response times and inspection access issues have complicated resolution verification.
