Augrented Insights Report for 42 Thayer Street

The six-story building at 42 Thayer Street in Inwood, constructed in 1939, currently has 36 residential units and is owned by 42 Thayer LLC. The property has experienced ongoing maintenance issues in recent years, particularly in 2024, with multiple reports of water leaks, mold, and plumbing problems.

Most notably, Apartment 2D has received multiple violations for mold (greater than 10 square feet) and plumbing issues including a defective sink drain pipe, while Apartment 4D has violations for kitchen water leaks, plastered surface problems, and the presence of roaches. The building has undergone several rodent control measures in 2024, with multiple bait applications and inspections showing rat activity, though a March 2025 inspection passed. Significant historical events include multiple construction-related violations in 2019, resulting in fines related to scaffold safety and tenant protection plan compliance, though most of these were subsequently dismissed.

The building's maintenance record shows regular issues with water leaks (documented as "slow leaks"), water damage to walls and ceilings, and various plumbing problems. Bedbug reports from 2019 through 2024 indicate some infestations with successful eradications, though recent filings show no current infestations. The property has received multiple 311 complaints and HPD violations in 2024, including recent complaints about mold and plumbing issues in September 2024 that resulted in violations being issued, though these complaints were inspected and closed.
