Augrented Insights Report for 634 Carlton Avenue

634 Carlton Avenue is a 4-story, 7-unit New Law Tenement building constructed in 1931 and currently owned by Howard Hershkovich. The building has experienced recurring heat and hot water issues over the past several years, with six documented complaints between 2020 and 2023, though in most cases, HPD was informed that the problems had been resolved before inspection. The property has also faced rodent challenges, particularly in 2021-2022, with multiple inspections revealing rat activity and the need for bait application.

Building maintenance violations have been documented, including failures to file annual bedbug reports in 2021-2022 and issues with smoke detector requirements and public hall maintenance in 2021. More recently, the building has encountered compliance issues with external low-pressure inspections, with violations issued for 2018-2021 inspections in June 2023 that remain active as of 2025. The Department of Buildings has active complaints regarding illegal conversion (2025) and a Local Law 188/17 compliance inspection (2024) that was completed with no enforcement action required.

Environmental inspections have shown minimal bedbug activity, with reports from 2021-2024 showing zero infested units. While there were some food establishment-related complaints in 2021, including odor issues and rodent sightings, these were addressed and closed. The building's permit history includes a relevant permit for work issued in September 2020, and an environmental control board violation from 2018 related to final inspection filing, though no penalty was imposed.
