More recently, the property has experienced a series of concerning sewer-related incidents, with four documented sewage back-up discharge events from the side sewer vent occurring between November 2024 and January 2025, all of which required intervention from PUC Sewer Operations and were marked as resolved through field work.

The building's immediate vicinity has faced challenges with urban debris management, particularly in late 2024, with multiple reports of abandoned furniture and other debris on the street and sidewalk (including incidents on November 12, 2024, involving a mattress and several furniture items). The most recent incidents include a blocked sidewalk case involving an unlicensed scooter in January 2025, representing a minor mobility concern.
