Augrented Insights Report for 420 West 23rd Street

The 11-story, 38-unit building at 420 West 23rd Street in Chelsea, owned by Frederick Rudd and constructed in 1985, has experienced several significant maintenance issues over recent years. The most pressing concerns have been recurrent heating system problems, with two emergency complaints about insufficient heat or hot water in 2024 (December) and 2023 (February), and two similar incidents in 2021 and 2021, though inspections in 2023 and 2024 found no violations. The building also faced a notable water leak incident in 2021.

Compliance and safety issues were addressed in 2021 when violations were issued for apartment 8C relating to defective smoke and carbon monoxide detectors, and door closure mechanisms, though these were certified as corrected by March 2021. An emergency violation was issued in December 2021 regarding improper waste line materials in the basement, with a penalty of $1,562. The building's management has maintained an active bedbug monitoring program, with the most recent report for 2023-2024 showing no infestations, and previous years' reports consistently documented zero infested units.

Additionally, regular rodent inspections have been passed consistently between 2010 and 2024, indicating effective pest management. The property has demonstrated compliance with housing maintenance code requirements, with all violations being addressed and closed, including annual bedbug reporting requirements fulfilled in 2024. Recent permits from 2018 suggest ongoing maintenance and compliance efforts, though no specific details on the nature of the work are provided in the available data.
