3545-3547 Scott St, San Francisco, CA 94123

The property at 3545-3547 Scott Street is a two-unit, two-story multi-family residential building located in the Marina neighborhood. Built in 1925 and owned by John B Sr & Antoinette A Ca, this flats and duplex-style building has undergone several significant improvements over the past decades. Most notably, in 2022, a solar system was successfully installed, comprising 12 roof-mounted PV modules with a total rating of 4 kW.

The building has seen substantial infrastructure improvements, including a comprehensive foundation upgrade with grade beams and new slab installed in 1990, and soil enhancement through compaction grout in the same year. Multiple renovations were completed in 2000, including kitchen and bathroom upgrades valued at $80,000, along with roofing work costing $7,900. The building has experienced recurring sewer issues, with reports of sewage backups in 2018, 2020, and the most recent plumbing work in 2012 involving sewer repair/replacement, though these appear to have been resolved promptly.

The property's maintenance history shows regular upkeep, including window replacement work planned in 1997 (though the permit expired) and reroofing projects in 1991. While there have been some minor incidents affecting the property and surrounding area, such as a small number of parking violations and sidewalk-related issues between 2020-2025, these appear to be typical urban challenges. Two fire alarm incidents were recorded, though neither resulted in civilian injuries or significant damage. The building's permit and maintenance history suggests ongoing investment in infrastructure and systems, with particular attention to energy efficiency through the recent solar installation and past roof replacements.
