Augrented Insights Report for 423 16th Street

423 16th Street is a 4-story, 16-unit New Law Tenement building located in South Slope and owned by Joe Montalto. The 1920 structure has experienced persistent rodent-related issues, with recent inspections in 2025 consistently showing rat activity, including a June 2025 Department of Health and Mental Hygiene (DOHMH) violation for conditions attracting rodents. The building has a documented history of unsanitary conditions, with multiple complaints and violations related to pests between 2021 and 2022.

In 2022, there was a specific violation recorded for mice infestation in Apartment 5. Several service requests, including unsanitary conditions related to garbage/recycling storage, door/window issues, and plaster/paint problems, were documented between 2021 and 2022, though inspections were often unable to gain access for verification. The building has maintained a clean record regarding bedbugs, with no reported infestations in the past several years, including the most recent 2024 report showing zero infested or eradicated units.

However, there is an outstanding violation from June 2023 regarding the failure to file the 2021 external low-pressure inspection. Though the building has undergone regular rodent inspections, with some passing compliance checks, the recurring rat activity suggests ongoing challenges with pest management. The property has addressed various safety and maintenance requirements, as evidenced by the closure of multiple violations, though some issues, particularly related to pest control, appear to be persisting.
