313 West 99th Street is an 8-story, 33-unit residential building located in Manhattan's Upper West Side, built in 1911 and currently owned by Mark Hoffman. The building has experienced several significant issues over the past few years, with the most critical being a recent rodent infestation identified in July 2025, marking the first rat activity in eight years of inspections. Other notable recent violations include a bedbug reporting requirement violation in March 2023, though subsequent filings through 2024 show no reported infestations or eradications. The building has a history of occupancy-related violations, including a 2021 Environmental Control Board citation for unauthorized occupancy of cellar spaces and common areas, which resulted in a $3,125 penalty. The property has demonstrated some regulatory compliance, as evidenced by the timely bedbug reporting submissions from 2019 to 2024 showing zero affected units, and recent permit activity in December 2023 for plumbing work.
The building's maintenance record reveals a mix of compliance and violations, including a 2023 violation for failing to submit an energy benchmarking report, though this was subsequently dismissed. Inspection records show generally good maintenance history, with the exception of the recent rodent activity and a failed inspection for unspecified reasons in September 2023. Previous complaints have been resolved without finding violations, including concerns about illegal commercial use and vent/exhaust issues in 2020 and 2021. The building has consistently filed its bedbug reports annually, demonstrating compliance with this specific requirement despite initial violations.
