111 8th Avenue, Brooklyn, NY 11215

This four-story, ten-unit building at 111 8th Avenue in Park Slope, owned by Jon Diacomanolis, was constructed in 1892 and has undergone a Class A conversion. The property has experienced several maintenance issues over the past five years, with significant concerns regarding external pressure system inspections.

Four violations were issued on June 20-30, 2023, related to failures to file external low-pressure inspections for the years 2018 through 2021, and there remains an open violation from the Department of Buildings characterizing this as an active issue. The building has seen sporadic maintenance issues regarding windows and frames, with three separate complaints filed in November-December 2018, though these were closed due to inspectors being unable to access the reported areas. Notably, there is an open Housing Maintenance Code violation from 1988 concerning proper posting of heating system access information that has not been addressed in over 30 years.

However, the property has maintained a clean record in more recent pest management, with no reported bedbug infestations in the past five reporting periods from 2021 to 2025. Rodent inspections have generally been favorable, with the building passing five consecutive inspections between 2017 and 2019, though there was one failure noted in December 2016 for unspecified reasons. A renovation permit was issued in June 2020, but the nature of the work is not specified in the available data.
