Augrented Insights Report for 172 South 9th Street

172 South 9th Street is a 4-story, 4-unit tenement building located in Williamsburg, built in 1910 and currently owned by Chananya Grosz. The building has experienced recurring issues with compliance, particularly regarding bedbug reporting requirements, with open violations noted in 2024, 2023, 2022, and 2021 all citing non-filing of annual bedbug reports as required by the Housing Maintenance Code. More concerning were incidents in 2023 when a partial vacate order was issued due to egress issues related to a removed fire escape, and a partial stop work order was placed regarding unauthorized excavation work that exposed footing for posts, though this violation was subsequently resolved.

The building has undergone multiple Local Law 188/17 Compliance Inspections with various outcomes, including one instance in 2024 where the inspector was unable to gain access. The property has a history of maintenance and safety compliance issues, including several violations in 2018 that were ultimately resolved, such as the need for proper gas leak notification procedures, cleaning requirements for the roof, and maintenance of public hall areas. Recent developments include an active ECB violation from November 2024 related to unauthorized construction fencing in the rear yard, with a penalty of $1,250.

The building's rodent inspection history shows both active monitoring and treatment from 2010 through 2019, with some periods of rat activity noted, though the most recent inspections have shown improved conditions with passed inspections. The building's documented history suggests ongoing challenges with regulatory compliance and maintenance, particularly regarding egress safety and pest management, though some improvements appear to have been made in recent years. The property has had various inspections and follow-up actions regarding safety protocols, including gas safety, emergency egress, and pest control, indicating regular oversight by city agencies.
