686 2nd Avenue, Manhattan, NY 10016
The 83-unit, 6-story building at 686 2nd Avenue in Murray Hill, owned by Marcy Kornblum and constructed in 1941, has experienced several significant events over recent years. Most notably, a serious 4-alarm fire occurred in March 2021, impacting roof areas above units 6K, 6H, and 6J, resulting in substantial damage requiring extensive repairs. Following the fire, multiple violations were recorded relating to damaged roofing and structural elements, though these were ultimately dismissed after proper repairs were completed and documented. The building has faced recurring rodent-related issues, with the most recent inspections in 2025 showing rat activity, following similar complaints in 2021 and an earlier 311 service request in 2025.
Between 2023 and 2024, the property underwent various improvements, including addressing self-closing door mechanisms at the main entrance and bulkhead, though violations were issued for defective doors. The building has maintained an active bedbug monitoring program, showing no reported infestations in recent years (with reports indicating zero infested or re-infested units from 2022 to 2024). Recent inspections in early 2024 found a gas supply issue in apartment 4J, and various maintenance items have been addressed, including window repairs and the need for improved garbage storage conditions. The property has undergone regular regulatory scrutiny, with consistent compliance inspections showing mixed results.
While recent rat activity has been documented in 2025, prior inspections from 2012 through 2018 generally passed without major issues. The building's management has responded to various housing maintenance code violations, including a 2023 requirement for annual bedbug reporting and 2024 violations related to door repairs. Recent Department of Buildings (DOB) complaints from 2023 regarding site conditions and structural stability were investigated, though no violations were warranted at the time. The building's energy efficiency documentation appears to have some outstanding requirements, as indicated by a 2021 DOB violation for failure to display the energy efficiency score and grade.
