418-420 Mississippi St, San Francisco, CA 94107

The two-story multi-family residential building at 418-420 Mississippi Street in Potrero Hill, owned by the Anavy Family Trust, consists of three units and was constructed in 1900. The property has experienced several significant maintenance issues over the past years, with the most pressing concerns occurring between 2017 and 2018. During this period, the rear deck and stair repairs were addressed following a violation notice filed in January 2017 that documented structural problems and dry rot in the approximately 15ft x 20ft deck.

The owners completed multiple repair projects including sistering of the brick foundation, back porch repairs, and deck repairs, all with associated permits in 2017. A plumbing permit from January 2018 indicates installation of a floor drain and trap primer, though this permit has since expired. More recent maintenance concerns have focused on sewer infrastructure, with three service requests between 2022 and 2024 indicating issues with the side sewer vent cover and sewage backup.

The building's exterior areas have also presented challenges, with multiple 311 calls regarding sidewalk defects (December 2022), hazardous materials (August 2021), and tree-related concerns (February 2020 and May 2021) suggesting ongoing infrastructure maintenance needs. The property underwent an electrical upgrade in 2004 with an underground conversion to a 100-amp termination enclosure in the garage, and the roof was addressed in 1998 though that permit is listed as expired. While the major structural issues from 2017 appear to have been addressed, the building continues to experience periodic maintenance needs, particularly regarding its exterior infrastructure and utilities.
