AI summary · updated June 2026

The 5-story tenement building at 186 Columbus Avenue in the Upper West Side, owned by Deborah Kasner and constructed in 1886, has maintained consistent property management practices over recent years. The 16-unit building has experienced several notable health department inspections, particularly regarding food establishment compliance between 2023 and 2024, though these issues appear to have been resolved based on closure notices. While there were multiple smoking violation complaints recorded in 2023, and some ventilation issues noted in 2022, these were also subsequently addressed according to closure documentation.

The building's maintenance record shows regular attention to pest control, with annual bedbug reporting from 2020 through 2024 indicating zero infested units during these periods. Rodent inspections have yielded mixed results, with three "passed" inspections in 2023-2025, though there were instances of rat activity noted in 2022. The property has had three significant housing maintenance code violations in 2017 related to heating, hot water, and access to the heating system in the 2FS apartment, all of which were subsequently addressed. Two environmental control board violations were recorded in 2018-2019 regarding construction work and false certifications, but both were resolved with no penalties imposed. The building has maintained regular permit activity, with several permits issued between 2018-2020 for various repair and maintenance work, including plumbing and electrical systems, with work generally being completed as per records. More recently, rodent inspections in 2025 showed the building has been effectively maintaining pest control standards.
