1309 Harrison St, San Francisco, CA 94103

The two-unit, two-story multi-family residential building at 1309 Harrison Street in the South of Market neighborhood, owned by Peter and Gail Knadler, dates back to 1906. The property underwent significant renovations in late 2014, including a complete electrical rewiring, furnace replacement with new ductwork, window replacements, and plumbing upgrades totaling approximately $84,920. These improvements were part of a comprehensive update to the building's systems.

However, the building has experienced recurring fire safety concerns, with violations issued between 2018 and 2023 for issues related to alarm systems, sprinkler systems, combustible materials, and sleeping area requirements. The property has also been subject to multiple fire department responses, though most were for false alarms or non-fire-related incidents, with no civilian injuries reported. More recently, between late 2024 and early 2025, there have been several 311 calls regarding the vicinity of the building, primarily related to encampments, graffiti, and abandoned items on the street.

The property was notably affected by a homelessness-related incident in December 2024. These external issues, while not directly impacting the building's safety systems, may affect the immediate neighborhood environment. The most recent fire safety violation from December 2023 regarding sleeping area requirements remains open as of the latest data review in October 2023.
