325-327 Missouri St, San Francisco, CA 94107

The two-unit residential building at 325-327 Missouri Street in Potrero Hill is a two-story flats and duplex structure built in 1900, currently owned by Lucas & Katherine Ottoboni. The property has undergone several significant improvements over the past decades, with the most substantial recent work completed between 2019-2020, including a comprehensive kitchen and bathroom remodel in Unit #327 with new electrical installations, and a 200-amp electrical service upgrade that benefits both units.

Earlier improvements show attention to structural integrity and sustainability, with a voluntary seismic upgrade through anchor bolts and plywood sheathing completed in 1996, window replacement work in 1997, and the installation of a solar system with five roof-mounted PV modules in 2011. The building's maintenance history indicates regular upkeep, with a complete reroofing project in 2006 costing $11,600, and various other permit-approved improvements.

The property has experienced some neighborhood-related issues, as documented in 311 calls, including three reports of sidewalk parking (2017-2021), a curb defect (2022), and instances of street cleaning needs (2020). While these external issues were generally resolved by city authorities, they suggest occasional challenges with the immediate urban environment. The building's maintenance record, particularly the significant 2019 renovations and infrastructure improvements, demonstrates ongoing investment in both the building's systems and resident living conditions, with no recorded safety violations or major infrastructure concerns in recent years.
