Augrented Insights Report for 423 Madison Avenue

423 Madison Avenue is a 4-story, 7-unit residential building constructed in 1930, currently owned by 423 Madison Avenue L.L.C. The building has experienced recurrent plumbing issues, with multiple complaints about water supply problems documented between 2022 and 2024, including three separate violations related to inadequate hot and cold water supply in Apartment 7, which were finally certified as corrected in July 2023.

Other significant maintenance issues have included heat and hot water problems, an inspection in 2022 revealed violations regarding defective self-closing doors and a bell/buzzer/intercom problem in Apartment 7. The building has undergone regular inspection under the Local Law 188/17 Compliance Inspections program, with recent active complaints filed in September 2024. Historical records show past health and safety concerns, including a 2019 complaint about rodent/insect issues in a food establishment, though this was ultimately administratively closed.

The property maintains a consistent record of submitting Bedbug and Rodent Inspection reports, with no recorded infestations or violations in recent years. Historical maintenance issues from 2008 included problems with fire retardant material in the public hall ceiling and encumbrances of garbage and household items in common areas, which were addressed and closed by 2018. The building's systems have been subject to regular tenant safety inspections, with no violations documented in the last several years, and all previous bedbug reports show zero infested units, indicating effective pest management practices.
