Augrented Insights Report for 89 Thayer Street

89 Thayer Street is a 6-story, 66-unit residential building in Inwood, constructed in 1920 and currently owned by Matthew Moslin. The building has experienced recurring heating system issues, with multiple complaints about heat and hot water problems documented from late 2024 through early 2025, although some were marked as duplicates of ongoing building-wide conditions.

More recently, in June 2025, there have been multiple open violations including concerns about appliances (refrigerator, electric/gas range), cabinets, windows, and mold, all marked as non-emergency or emergency conditions. The building's elevator system has been a persistent concern, with multiple complaints between 2022 and 2025 regarding "No Alternate Service" situations, with the most recent active complaint dated May 2025. Significant violations include documented rat activity, with inspections throughout 2023-2025 consistently indicating rodent presence, and mold issues in residential units.

The property has also faced regulatory scrutiny, receiving Environmental Control Board violations related to improper fuses and elevator service requirements, with penalties imposed in 2022 and 2024. While there have been bedbug infestations reported between 2019 and 2024, the most recent three reporting periods (2022-2025) indicate no active infestations. The building has open maintenance issues as of June 2025, including problems with flooring, cabinetry, and various appliances, suggesting ongoing challenges with property upkeep and maintenance response times.
