3922 Irving St, San Francisco, CA 94122

The Zeng Family Trust owns this 3-unit, 2-story multi-family residential building located at 3922 Irving Street in the Outer Sunset neighborhood. Built in 1961, the property has undergone several significant events, most notably a 2009 enforcement action that revealed an unauthorized basement unit, leading to a permit (200910158999) requiring the removal of an illegal kitchen, shower, and conversion of various rooms back to storage space, with a cost of $7,500.

This violation case (200918183) raised serious safety concerns regarding fire-rated construction materials, egress, and building code compliance. Prior to this, in 2007, unit #3 underwent legitimate repairs including kitchen cabinet restoration, plumbing work, and electrical upgrades totaling approximately $14,000. The building has a history of fire safety-related issues, with violations documented in 2001 and 2009 regarding fire escape maintenance, fire extinguisher charging, and central alarm system repairs, though all were subsequently abated.

More recently, the building has undergone routine housing inspections in 2018, with all violations appearing to be resolved. The property's maintenance history shows attention to basic building systems, though the 2009 incident highlights historical concerns about unauthorized modifications. Recent activity at the address has primarily involved external issues such as parking violations, graffiti, and encampment-related matters on the surrounding public spaces, with the most recent incidents occurring between 2022 and 2024, though these do not directly impact the building's internal conditions or safety systems.
