Augrented Insights Report for 21 Claremont Avenue

21 Claremont Avenue is a 10-story, 47-unit New Law Tenement building constructed in 1910 and currently owned by Monica Kuth. The building has undergone several inspections and maintenance activities over the past five years, with the most recent significant events including a April 2024 outside building inspection focusing on the porch/balcony area, and multiple facade-related violations issued to Columbia University Trustees between 2020 and 2024.

These facade violations, dating back to 2021, noted issues such as vertical cracks, spalled bricks, and failure to submit required examination reports, with associated penalties totaling $5,000. The building has maintained a good record regarding pest control, with zero reported bedbug infestations in the past five reporting periods (2020-2024), and has successfully passed multiple rodent inspections between 2016 and 2025. The property has experienced periodic maintenance issues, including a paint/plaster wall complaint in 2019 that could not be inspected due to access issues, and elevator problems noted in a 2020 complaint that resulted in an Oath violation.

Compliance inspections in 2023-2024 were conducted under Local Law 188/17 and CSE: Sweep, with no violations warranted. The building has also had recurring violations related to the submission of Environmental Control Board (ECB) reports and Elevator Inspection Reports (EER), though records indicate these violations were ultimately dismissed in 2025. The property has maintained regular permit activity for various maintenance and repair works, with multiple permits issued between 2018 and 2020 for electrical and plumbing work.
