Augrented Insights Report for 40 Thayer Street

The 72-unit, 5-story New Law Tenement at 40 Thayer Street in Inwood, built in 1927 and currently owned by Sherman Nagle Realty Corp, has experienced several significant maintenance and safety issues in recent years. Most notably in 2025, there have been multiple complaints regarding indoor air quality and mold issues, with an open complaint from February 2025 still unresolved as of October 2023. The building has also faced recurring rodent problems, with the most recent inspection in July 2025 showing rat activity, though it passed the inspection.

Numerous Housing Maintenance Code violations remain open, particularly in Apartment C6, including issues with window guards, smoke detectors, and pest infestations recorded in July 2024. The building's infrastructure has shown concerning patterns, with multiple 311 service requests regarding window frames, flooring, and wall conditions, and emergency heating/hot water issues reported in January and December 2024. Historical records from 2021-2022 reveal a pattern of maintenance challenges, including multiple complaints about work done without proper permits.

Environmental Control Board violations from 2021 document issues with rooftop debris and building maintenance standards, while more serious violations regarding gas piping installation and electrical work were recorded in 2019. The building's response to pest control has been variable, with three units affected by bedbugs in 2019-2020, though no infestations were reported in subsequent years. The Department of Buildings has conducted multiple inspections under the Rodent Control Program, with mixed results including both passed and failed inspections, suggesting ongoing challenges with building maintenance and compliance.
