Augrented Insights Report for 100 South 4th Street

100 South 4th Street is a six-story, 74-unit residential building in Williamsburg, constructed in 1910 and currently owned by 100 S 4th St LLC. The property has experienced recurring indoor air quality issues in 2025, with multiple complaints about chemical vapors, gases, and odors in June. There is also a recent façade safety concern cited as "Unsafe Notification" under Local Law 11/98 from November 2024 that remains active.

The building has a significant history of pest-related issues, particularly regarding rodents and unsanitary conditions, with several 311 complaints and HPD inspections throughout 2025. While some inspections found no violations, at least one inspection resulted in violations requiring correction. The elevator system has been a recurring maintenance focus, with several violations from 2019-2023 related to safety systems and compliance issues. A gym facility ("Session") operating on the first floor was the subject of multiple complaints and violations between 2019-2020 regarding illegal occupancy and use contrary to the building's certificate of occupancy.

The building has demonstrated relatively good bedbug management, with reports from 2019-2024 showing zero infested units or required eradications. Water issues have been documented, with emergency complaints about leaks in 2020 and 2024. Recent rodent inspections in 2025 have passed, though previous inspections in 2023 indicated rat activity. Current violations include the failure to file required FISP Cycle 9C technical reports by February 2024.
