909 Summit Avenue, Bronx, NY 10452

909 Summit Avenue in Highbridge is a 3-unit, 3-story residential building constructed in 1905, currently owned by Dorothy Thomas. The property has a troubling history of building code violations and maintenance issues, with the most recent being three active violations issued in April 2024, including an unauthorized conversion of the cellar into an additional Class 'A' apartment, which was found to be occupied with complete bathroom facilities; deterioration of metal cornice molding and facial boards creating safety concerns; and unauthorized construction work including new partition walls. These violations represent substantial safety concerns and result in significant penalties totaling $31,250.

The building has consistently failed to file required annual bedbug reports from 2021 to 2024, maintaining an open Class A violation. The property has an extensive history of Department of Buildings violations related to unauthorized construction work, particularly concerning cellar modifications. Multiple violations from 2019 through 2024 indicate a pattern of non-compliance, with penalties totaling over $100,000, including failure to comply with commission orders and work performed without proper permits.

More recent rodent inspections have shown variable results, with rat activity reported in 2024, though the most recent inspection in March 2025 passed. While the building has maintained compliance with rodent inspection requirements overall, the persistent issues with bedbug report compliance and unauthorized construction suggest ongoing management challenges. The property's building class is listed as "HERETOFORE CONVERTED CLASS A" which may indicate previous conversion issues, and it has undergone multiple illegal conversion investigations between 2019-2024, including work performed without permits or with unauthorized changes to occupancy use.
