Augrented Insights Report for 504 Classon Avenue

The four-story, three-unit building at 504 Classon Avenue in Clinton Hill, owned by George Murray and built in 1930, has experienced several notable maintenance and safety issues over recent years. Most concerning are ongoing rodent problems, with multiple "Rat Activity" inspections recorded between 2021 and 2023, including recent reports in June and October 2023.

The building has faced plumbing issues as evidenced by a July 2024 complaint regarding bathtub/shower problems, though an inspector was unable to gain access to investigate. Housing Maintenance Code violations have also been documented, with bedbug reporting violations noted in 2021, 2022, 2023, and 2024 inspections, though recent filings for 2024-2025 show no units with infestation, eradication, or re-infestation. Other historical issues include a blocked egress complaint in 2021, an electrical wiring complaint in 2018 (though no violations were found upon inspection), and an illegal storefront sign complaint in 2018 that resulted in an Oath Violation.

Environmental Control Board violations were issued in 2021 for overgrown vines on a fire escape and in 2018 for unpermitted work related to a sign installation, though records indicate these were resolved. The building has undergone some maintenance work, as shown by the issuance of electrical work permits in June 2019. While the building has had various complaints and violations over the years, it's worth noting that many issues have been addressed or resolved through inspections and corrective actions, though the recurring rodent activity remains a significant concern.
