310 West 99th Street, Manhattan, NY 10025

310 West 99th Street is a 7-story, 66-unit Old Law Tenement building located in Manhattan's Upper West Side, built in 1902 and currently owned by David Margous. The building has experienced several maintenance issues in recent years, with the most concerning being a cluster of violations identified in June 2023 in apartment 607, including problems with essential safety systems such as missing smoke detectors, non-functional carbon monoxide detectors, and rodent infestation.

Additional maintenance issues were documented throughout 2023, including concerns with flooring, walls, and various infrastructure elements, though most inspections resulted in no violations being issued. The building appears to have undergone proper periodic rodent control measures, with inspections showing bait application in 2025, though there have been occasional rodent-related complaints, including a recent one in May 2025 that resulted in a passed health inspection. The property's history shows a pattern of maintenance concerns primarily related to basic infrastructure and safety systems, though there have been no documented bedbug infestations in recent years, with consistent reports showing zero affected units since 2019.

While several complaints have been filed regarding unauthorized commercial use and debris issues in the past, inspections typically resulted in no violations being found. The building has maintained compliance with most housing maintenance requirements, demonstrating a regular schedule of permit applications for maintenance work, though one notable violation related to not filing the FISP Cycle 8B Technical Report on time in 2018 was recorded, it was subsequently deleted due to late re-filing. The property has also experienced some difficulty in allowing access for inspections on occasion, as seen in several closed complaints from 2022.
