4131-4133 Balboa St, San Francisco, CA 94121

The two-family residential building at 4131 Balboa Street in San Francisco's Outer Richmond neighborhood is a two-story flats & duplex structure built in 1947, currently owned by Michael M. Shiro. The property has undergone several significant modifications in recent years, with the most substantial work occurring between 2023 and 2024.

Currently in process is the removal and replacement of rear decks for both 4131 and 4133 Balboa Street, for which permits have been issued with a cost of approximately $38,450. In late 2024, the property successfully completed the demolition of an existing rear yard storage room, which was previously subject to legalization attempts in late 2023. The building has also undergone several necessary code compliance updates, including electrical system improvements, plumbing corrections (such as laundry drain modifications and gas pipe strapping), and safety features installation as mandated by a physical inspection report (CC-8619) in 2023-2024. Earlier improvements to the property include a complete reroofing in 2017, window replacements throughout the building, and various maintenance updates.

The building's maintenance history shows attention to both aesthetic and safety concerns, with recent work focusing on compliance with current building codes and requirements. A notable historical issue from 1995 regarding a potentially unstable dirt wall between properties was quickly addressed within three days. The property has had occasional parking-related complaints (two driveway blocking incidents in 2022) and one instance of sidewalk graffiti (2012), though these are not directly related to the building's condition or safety. The most recent significant building improvements, including deck replacement and storage room modifications, suggest ongoing investment in the property's infrastructure and compliance with current regulations.
