397 Third Avenue, Manhattan, NY 10010

397 Third Avenue is a 20-story, 108-unit residential building located in Gramercy, completed in 2021 and currently owned by Patricia Pettwaybrown. The building has experienced several notable maintenance issues since its completion, with the most recent being a heat and hot water emergency in December 2024 that required intervention from the Department of Housing Preservation and Development (HPD).

Prior to this, there have been recurring issues with unauthorized after-hours work in late 2024, though investigations did not warrant any violations. Throughout 2023-2024, multiple violations were recorded for failure to file required external low-pressure inspections, but these were ultimately dismissed. The building faced some construction-related challenges during 2022, including excessive debris and site conditions endangering workers, though following inspections, these largely resulted in Oath Violations and a fully rescinded Stop Work Order.

The property's maintenance history also includes a window pane issue in 2019 that HPD could not inspect, and a 2018 Department of Health and Mental Hygiene complaint regarding rodents/insects/garbage in a food establishment, which received official written notification to the owner. On a positive note, the building has maintained a clean bedbug record for the past two reporting periods (2023-2024 and 2024-2025), with no reported infestations or eradications. While the building's relatively recent construction (2021) provides some assurance of modern standards, the recurring heat/hot water issues and recent unauthorized work concerns suggest ongoing maintenance attention may be required.
