4327 California St, San Francisco, CA 94118

The property at 4327 California Street is a two-unit, two-story multi-family residential building located in San Francisco's Inner Richmond neighborhood. Built in 1916 and owned by the Pellinacci Family Revocable Trust, this flats and duplex style building has undergone several significant maintenance and improvement projects over the past three decades. Most notably, in 2021, the building received substantial mechanical upgrades including the installation of a heat pump HVAC system and associated electrical work, as well as an electrical service upgrade to 225 amps.

The building experienced several important safety and habitability issues in early 2021, with violations filed in March and April of that year related to heating system failures, lead paint hazards, and safety equipment requirements (including carbon monoxide and smoke alarm affidavits). These violations were successfully abated by July 2021, along with necessary repairs including the installation of new heating systems. The building's historical maintenance record shows previous roofing work in both 1992 and 2005, though these permits have since expired.

Recent activity around the property has been documented through 311 calls, with several reports in 2024 related to sidewalk maintenance, street cleaning, and encampment management. As of October 2024, there are three open 311 cases including one regarding hazardous materials (glass) on the street/sidewalk area, though this is not directly related to the building's condition or habitability. The most recent building-related permit activity was for street space use in 2015, suggesting limited required external modifications in recent years.
