Augrented Insights Report for 521 East 83rd Street

The 15-unit, 5-story Old Law Tenement building at 521 East 83rd Street, owned by Frank Didio, was constructed in 1925 and has experienced several significant maintenance and compliance issues in recent years. Most notably, there are currently four open Housing Maintenance Code violations from 2021-2024 regarding the failure to file annual bedbug reports, while the building underwent multiple Department of Buildings (DOB) inspections in 2020 related to structural stability concerns during nearby construction, and there were several violations regarding building facade maintenance.

Dangerous facade conditions were documented throughout 2019-2020, with violations noting damaged or missing decorative masonry elements, particularly around windows, though these were eventually resolved with various penalties imposed. The building has shown general compliance with rodent control measures, passing inspections between 2017 and 2024, with the most recent rat sighting report in September 2023 resulting in no violations.

Historical complaints from 2019-2020 indicate multiple reports of building shaking/vibrations, though inspections found no violations at the time. The property has also undergone regular Department of Health and Mental Hygiene inspections, with only one documented pigeon waste complaint in 2021 and a rat sighting complaint in 2023, neither resulting in violations. While there have been several past violations regarding building maintenance and construction compliance, many have been either resolved or dismissed, particularly those related to the failure to certify correction on immediately hazardous violations during 2019-2020.
