1401-1407 Mariposa St, San Francisco, CA 94107

The property at 1401-1407 Mariposa Street is a two-story, five-unit multi-family residential building located in Potrero Hill, built in 1900 and currently owned by Eleanor Lorraine Thompson R. The building has experienced recurring issues with dry rot over the years, with documented repairs needed in 2006 (back stairs), 2009 (siding), and as far back as 1998. A significant renovation occurred in 2017 with a kitchen replacement project costing $20,500, which included electrical and plumbing work, and was completed successfully with relative safety inspections showing normal results.

The building underwent several routine housing inspections between 2004 and 2015, including an illegal unit investigation in 1999, which was resolved by February 2000. While there were some maintenance concerns in the 1990s, including broken shower doors, these appear to have been addressed. The property has experienced various incidents in recent years, with the most recent issues being a series of graffiti incidents in 2023-2024 and one driveway blocking incident in early 2024.

The building's maintenance history shows attention to structural issues, particularly with the back stairs and siding, though some older permits for repairs have expired. The building had multiple routine safety inspections, and while there was a cancellation of a legalization permit in 1989, other historical records indicate efforts to comply with municipal codes. Recent 311 calls primarily relate to external issues such as graffiti and public infrastructure concerns rather than building-specific problems, with the most recent cases being resolved through standard city services.
