AI summary · updated June 2026

The six-unit, four-story tenement building at 807 Nostrand Avenue, owned by Harry Dewar Realty Inc, has experienced numerous maintenance and compliance issues over the past several years. Most notably, in early 2025, there were multiple complaints and violations related to heat and hot water issues, with several complaints indicating no access for inspection and at least one instance where heat and hot water were reportedly restored before inspection. The building has also faced significant water-related problems, with open violations from December 2024 regarding leaky faucets and waterlogged bathtub issues in apartment 4, as well as water supply and sanitary conditions resulting in multiple complaints in April 2025. The property has active violations for failing to file required annual boiler inspection reports since 2023, with a penalty of $312.00 recently imposed for this non-compliance.

The building's maintenance history reveals persistent infrastructure challenges, including multiple complaints about plumbing, window frames, flooring, and mold issues throughout 2025. There are also ongoing concerns about rodent activity, with multiple inspections showing rat activity between 2022 and 2025, though bait was applied in some instances. Additional infrastructure problems include violations related to electrical work (2021), gas piping (2023), and various building code compliance issues. The property has active housing maintenance code violations from 2024-2025 affecting multiple apartments, including issues with windows, walls, and flooring. Several complaints about heating systems, plumbing, and general maintenance have been filed throughout 2025, indicating persistent maintenance challenges. The building's age (constructed in 1920) and these ongoing issues suggest a pattern of deferred maintenance and compliance challenges that may impact resident comfort and safety.
