400 Utah St, San Francisco, CA 94110

The two-unit residential building at 400 Utah Street in Potrero Hill is a two-story flats and duplex structure built in 1890, currently owned by Tran Lan. The building's maintenance history shows some significant infrastructure work, most notably a water main replacement completed in April 2023 and a complete re-roofing project finished in 1989. The property has experienced several recent challenges between late 2024 and early 2025, with multiple 311 calls reporting various issues including three separate incidents of garbage and debris (one involving a mattress), two encampment situations, a damaged tree, and an ongoing issue with overgrown trees blocking the sidewalk.

Additionally, there is a concerning open case regarding a collapsed sidewalk that poses potential accessibility and safety concerns. The building's street has also faced some cleanliness issues, with multiple reports of debris requiring attention, though many of these cases were resolved promptly by city services. The property's historical maintenance record shows some attention to basic infrastructure needs, including a street space permit issued in 2016.

The only recorded fire incident was a power line issue involving PG&E, which resulted in no civilian injuries. Planning records indicate no violations have been filed against the property. While the recent plumbing upgrade demonstrates some maintenance activity, the current concentration of street-level issues, particularly the collapsed sidewalk and tree-related problems, suggests there are multiple ongoing environmental challenges in the immediate vicinity of the building.
