322-326 Harriet St, San Francisco, CA 94103

The two-unit residential building at 322-326 Harriet Street in San Francisco's South of Market neighborhood, owned by Donald Piermarini, has a relatively long history dating back to its 1924 construction as a flats and duplex building. The property has undergone limited documented renovations, with records showing an office addition at the rear completed in 1983 and a street space permit issued in 2009.

The building has experienced several fire safety system issues in recent years, with violations noted in 2024 for sprinkler/standpipe systems and alarm systems, following earlier alarm system violations in July 2024. While no civilian injuries have been reported in recent fire incidents, there have been multiple false alarms and smoke detector activations. The property has faced noticeable infrastructure challenges in late 2024, including a sewage back-up discharge from a catch basin in mid-December and several instances of garbage and debris requiring municipal attention.

The building's immediate vicinity has experienced recurring street maintenance issues, with multiple reports of waste disposal problems, including human waste and needles, particularly during November 2024. While these external environmental concerns are notable, they primarily relate to the surrounding area rather than the building itself. The only documented building-specific safety concern in recent years was a wood utility ladder identified at the rear of the property in late 2009, which was subsequently addressed.
