441-445 Mississippi St, San Francisco, CA 94107

The three-unit residential building at 441-445 Mississippi Street in Potrero Hill, owned by the Wilma Swinson Revocable Trust, is a three-story flats and duplex structure built in 1900. The property has undergone several significant improvements over the years, with the most recent major work occurring in 2013 when an attempt was made to extend the backyard fence height from four to six feet, though this led to a building complaint about unauthorized work and fence height violations.

Prior improvements include an $8,000 entry stair replacement with elevated concrete stairs in 2004, and several renovation projects in the 1980s including bathroom repairs, window replacements, and facade work. The building's maintenance history shows attention to structural elements, with a reroofing project initiated in 2000 (though this permit expired) and a previously cancelled front staircase replacement project in 1985. The property has undergone three routine housing inspections over the years (1999, 2010, and 2020), all of which are listed as not active.

More recent incidents include a leaking water valve in 2021, hazardous materials (glass) that required cleanup in 2021, and two service requests in 2018, all of which were resolved. The most recent external issue was a damaged tree reported in 2022, which was inspected and addressed by city services in early 2023. While the building's permit history shows regular maintenance and improvement efforts, the most notable concern would be the 2013 fence height violation, though this appears to have been addressed through the permit process.
