Augrented Insights Report for 423 Wythe Avenue

The 4-unit, 4-story old law tenement building at 423 Wythe Avenue in Williamsburg, owned by Gabriel Dorfman and constructed in 1910, has experienced several significant maintenance and compliance issues in recent years. Most notably, in March 2024, the property was cited for rodent violations by the Department of Health and Mental Hygiene, with follow-up inspections revealing rat activity in April 2024, though a subsequent compliance inspection in May 2024 resulted in a passing grade. The building has also faced multiple housing maintenance code issues, including a recent violation regarding bedbug reporting requirements (April 2024) and previous violations in 2022 related to carbon monoxide detector requirements and building registration signage.

Between 2021-2022, the building experienced a cluster of maintenance issues including power outages (February 2021), heat and hot water problems (February 2021), and multiple water-related issues (September 2022), though inspections by the Department of Housing Preservation and Development found no violations in these cases. The property has a history of addressing fire safety concerns, with a 2025 compliance inspection finding a previously existing issue regarding fire escape access from Apartment 4 was finally certified as resolved. Between 1983-1987, there were several code violations and safety concerns documented, including issues with illegal space usage and heating equipment in Apartments 3 and 4, which appear to have been addressed.

The building was subject to multiple illegal hotel room investigations, with the most recent occurring in early 2025, resulting in violation notices being served. Recent bedbug reports from 2020-2024 show no infestations during the annual reporting period, indicating effective management of this particular issue. The most recent inspection in 2024 specifically addressed rodent activity, which has been a recurring concern for the building, with both initial and compliance inspections noting issues in early 2024 and mid-2024.
