515 Wisconsin St, San Francisco, CA 94107

The two-unit residential building at 515 Wisconsin Street in Potrero Hill is a two-story flats and duplex structure built in 1906, currently owned by Richard A. and Janice M. Fiore.

The property has undergone several significant infrastructure improvements in recent years, most notably in April 2015 when the building received comprehensive roofing work including plywood installation and complete reroofing, along with the replacement of shingle siding with cedar shingles on both front and rear facades, totaling approximately $26,500 in improvements. The building has experienced multiple fire alarm system activations over the years, with documented false alarms in 2018, 2015, and 2009, though all were promptly investigated and found to be malfunctions with no injuries reported. The property had one confirmed fire incident in 2009 related to a power line issue, but again, no injuries were reported. Recent activity at the property has primarily involved external maintenance and compliance matters, with a current open Rent Board fee housing inventory case from January 2025.

The surrounding area has experienced some issues with abandoned vehicles and street debris, particularly during late 2024, with multiple reports to various city agencies, though most vehicle-related incidents were resolved upon officer arrival. The building's maintenance history shows regular upkeep, including a bathroom reconstruction in 1987. A Department of Public Works referral was recorded in 2018, though this was marked disapproved. While the building has experienced recurring false alarms, there have been no documented instances of actual fire or safety hazards, and all systems appear to be promptly addressed when issues arise.
