Augrented Insights Report for 605 Carlton Avenue

The four-story, three-unit building at 605 Carlton Avenue in Prospect Heights, currently owned by Kellen Koon, has experienced several notable events since its 1931 construction. Most concerning are two active Department of Buildings violations from 2023 related to the failure to file external low-pressure inspections for 2019 and 2022, which remain unresolved as of fall 2025.

The building has consistently demonstrated good bedbug management practices, with all six annual reports since 2019 showing zero infested, eradicated, or re-infested units. Recent rodent inspections have shown improvement in the building’s pest management, with a passed compliance inspection in February 2025, following a rat activity report in 2022, and consistent compliance inspections showing passed results in previous years except for 2014 and 2013 when initial inspections noted rat activity. The property has faced various maintenance and compliance issues over recent years, including a 2024 DOHMH complaint regarding rodent/insect/garbage issues in a food establishment, though this appears to be related to a restaurant rather than the residential building.

Historical records show two Housing Maintenance Code complaints in October 2021 regarding an unsanitary condition involving pests and a door frame issue, neither resulting in violations. The building has also been subject to two vaccine mandate non-compliance complaints in 2021 and 2022, specifically regarding employee and customer proof of vaccination checks. While these health and safety concerns were addressed at the time, they represent the building's only documented public health-related issues.
