64-66 14th St, San Francisco, CA 94103

The property at 64-66 14th Street in San Francisco's Inner Mission neighborhood is a two-story multi-family residential building constructed in 1907, currently owned by Julio E & Frances J Osorio. The building underwent significant transformation in 2009, when the first-floor residential unit was converted into a commercial restaurant space, complete with a new front facade, handicap bathroom, and extensive commercial kitchen equipment including Type 1 hood, fire suppression system, and electrical installations for various appliances.

The renovation included window replacements, bathroom revisions, and new plumbing and gas installations, with construction costs exceeding $100,000. More recent improvements include a sewer replacement completed in 2021. The building has experienced recurring fire alarm system issues, with multiple alarm activations and complaints recorded between 2006 and 2024, though most were determined to be false alarms or system malfunctions with no civilian injuries reported.

A violation for the alarm system maintenance was issued and abated in April 2024. The property has also generated numerous 311 calls in early 2025 regarding various street and sidewalk issues, including graffiti and debris, with several cases remaining open as of January 2025. While the building underwent significant commercial conversion work in 2009, recent maintenance records and permits suggest limited major renovations or improvements have been undertaken in recent years.
