425-427 Connecticut St, San Francisco, CA 94107

The 425-427 Connecticut Street property in Potrero Hill is a 3-story, 2-unit multi-family residential building constructed in 1987. The building's maintenance history shows several significant structural and safety improvements, including the installation of a fire sprinkler system in 1985, underpinning work in 1994, and a complete sewer house trap and drain pipe replacement in 2017.

Recent maintenance includes repairs to dry rot on the back porch/deck in 2013. The building has experienced three housing inspection complaints regarding possible illegal units between 1994 and 1999, all of which were resolved, though documentation shows cancelled permits in 1990 and 1993 related to legalizing ground floor rooms. The property has undergone various improvements over the years, including window replacements (2003), roof work (1991), and membrane leakage repairs (1996).

Recent street-level issues documented through 311 calls primarily relate to external matters such as street cleaning, debris removal, and sidewalk maintenance rather than building-specific concerns. The most recent building-related work was the 2017 plumbing upgrade, suggesting no major building systems require immediate attention. The property appears to be properly classified as a two-unit building, based on the resolution of previous illegal unit complaints and the completion of necessary permits, though there have been historically documented concerns about unauthorized modifications.
