713 Sackett Street, Brooklyn, NY 11217

Located in Park Slope, 713 Sackett Street is a 4-story, 7-unit old law tenement building constructed in 1920 and currently owned by Michael Gatzonis. The building has experienced persistent maintenance issues throughout 2025, with multiple emergency service requests and Housing Maintenance Code complaints regarding water leaks, mold, and heating problems. Notable recent concerns include open violations from December 2024 regarding inadequate heating in Apartment 6 and various building-wide heating and hot water issues, particularly during winter months.

The building has documented multiple water-related problems, including heavy flow leaks and ceiling damage, with recent violations issued in June 2025 for unsanitary conditions, mold, and ceiling damage. The building maintains an active status with several open violations as of 2025, including issues with public hall ceilings on the 3rd and 4th stories, roof leaks, and access to the heating system. A Department of Buildings violation regarding failure to file the 2023 external low-pressure inspection was issued in September 2024.

While the building has documented rodent activity in late 2024 inspections, it had previously passed multiple inspections between 2018-2019. Bedbug reports from 2021-2022 indicated no infested units, suggesting successful management of this particular pest issue. The property's ongoing maintenance challenges, particularly concerning water damage, heating systems, and public areas, warrant attention, as evidenced by the volume of recent service requests and open violations.
