Augrented Insights Report

The three-unit multi-family residential building at 639-643 Baker Street, located in the Park North neighborhood, was constructed in 1900 and is owned by Andrew H. Tarnowka. The property has undergone several significant modifications and faced various challenges over the past few decades.

Most notably, in 2023, the building experienced multiple water-related issues resulting in violations for mold/mildew on ceilings, water damage, window glazing seals, and heating problems - all of which were abated by February 28, 2023. More recent activity includes a tenant buyout at 641 Baker Street for $67,500 in April 2024 and another at 643 Baker Street for $5,000 in July 2024. Current proposed improvements include an interior remodel of the 2nd and 3rd levels with new stairs and a dormer, as indicated in a permit filed in December 2024. The building has seen various infrastructure improvements over the years, including a 200-amp electrical service upgrade and common area panel installation in 2009, and new gas line and water heater installation in the ground floor/garage area in 2010.

Earlier records show roofing work in 1993 and asbestos removal in 1994. The property has experienced recurring heating issues, as evidenced by complaints in both 2023 and 2024 regarding non-functioning heaters. Recent tenant exits and buyouts suggest possible significant changes in occupancy, with the most substantial buyout occurring in April 2024. The building's maintenance history shows a pattern of addressing various systems and structural elements, though the recurrence of heating and moisture-related issues indicates ongoing challenges with these systems.
