233 Prospect Place is a 6-unit, 4-story residential building located in Prospect Heights, built in 1916 and currently owned by Jon Diacomanolis. The building has experienced recurring issues with food spoilage, with three complaints logged between December 2023 and February 2024, all of which were closed by the Department of Health and Mental Hygiene (DOHMH). From 2018 to 2019, multiple Housing Preservation and Development (HPD) complaints were filed regarding water leaks and paint/plaster issues affecting ceilings and walls, resulting in violations.
More recent building maintenance history shows active compliance inspections for Local Law 188/17 in 2024, though no enforcement action was required. The building's environmental violations history includes several concerning issues from 2019-2021, such as maintenance of a dilapidated metal cornice, multiple failures to comply with commissioner's orders, and HVAC-related violations. The building has maintained an active bedbug management record from 2019 to present, consistently reporting zero infested or re-infested units.
Recent inspections for rodent activity have shown mixed results, with initial inspections in 2023 showing rat activity, though the most recent inspection in May 2025 passed. There are currently four active DOB violations from 2023 related to failure to file external low-pressure inspection reports. The building's history includes previous issues with building shaking in 2021, and there have been multiple complaints regarding illegal vent/exhaust installations in 2019-2020, though these were subsequently resolved through Oath Violation processes. The property has also undergone multiple inspections related to various safety systems, with some violations requiring correction, particularly regarding smoke detectors and carbon monoxide detection systems in Apartment 1B, though records indicate these have been addressed.
