143 East 23rd Street, Manhattan, NY 10010
The 22-story, 326-unit building at 143 East 23rd Street, constructed in 1928 and currently owned by Molly Mattimore, has experienced numerous maintenance and safety issues through 2025. Recent complaints from May 2025 highlight ongoing problems with unsanitary conditions, particularly in garbage storage areas, as well as pest infestations. Multiple Housing Maintenance Code violations were documented in late 2024, including issues in apartment 9M related to carbon monoxide and smoke detector problems, and ongoing roach infestations in apartments 9M and 10D, which remain officially listed as open violations.
The building has also faced water and plumbing issues, including problems with hot water supply in multiple units and radiator concerns noted in 2024-2025. The property has a concerning history of elevator service complaints, with multiple reports between 2024 and 2025 regarding single device operation and alternate service problems, though inspections generally found no violations. In 2024, there were significant construction safety violations during facade work, resulting in penalties for GS Construction Group, though these were subsequently resolved.
The building's maintenance record shows regular rodent inspections, with some failures noted in 2025 and 2020, though recent inspections have passed. While the building has maintained compliance with bedbug reporting requirements, noting no infestations since 2021, the concentration of recent complaints suggests persistent maintenance challenges. The property has active environmental control board violations as of 2023 related to unauthorized awnings and signage, and historical violations dating back to 2020 concerning boiler conditions, though many past violations have been resolved.
