Augrented Insights Report for 4 West 109th Street

4 West 109th Street is a 6-story, 41-unit residential building located in New York City's Upper West Side, built in 1890 and owned by Jennifer Iwanicki. The building has a long history of maintenance issues, with systematic violations recorded in the late 1980s and early 1990s, including multiple instances of inadequate hot water supply, electrical service problems, smoke detector defects, and pest-related complaints.

Most notably, the building is currently facing three open violations related to fire safety signage, dating back to September 1999, specifically regarding the posting of smoke detector requirements, building registration number, and inspection certificate display near the mailboxes. Recent years have shown some improvement in specific areas, with the building undergoing regular rodent inspections between 2016 and 2024, all of which have passed.

The most significant recent structural concern was an "Unsafe" façade notification in January 2022, though a subsequent violation filed in February 2022 was dismissed by May 2025. The building has maintained a clean record regarding bedbug infestations since 2019, with the most recent reports from 2023-2024 showing no affected units. While the building has demonstrated progress in some maintenance areas, the persistent fire safety violation notices from 1999 and the temporary façade concern in 2022 suggest ongoing attention to basic safety standards.
