324-326 Mississippi St, San Francisco, CA 94107

The two-story multi-family residential building at 324-326 Mississippi Street in Potrero Hill, owned by Sean Corrado, has undergone significant renovations and faced several maintenance challenges since its construction in 1900. Most notably, in 2019, the property underwent substantial interior remodeling of both full-floor units, including kitchen and bathroom renovations, electrical rewiring, and the installation of a radiant heat system with combination boilers for each unit, totaling approximately $250,000 in improvements. During this period, there were also water damage repairs due to a leaking roof, and the installation of an attic access spiral staircase and dormers.

The building has experienced several maintenance issues over the years, including a potentially hazardous retaining wall situation in 2017 that prompted inspection and remediation (resolved in 2022), and a roof-related water damage incident in 2019. Historical records show previous violations related to heating system non-compliance (2000), gas line safety issues (2003), and unpermitted construction of rear decks in 2016, though these have all been resolved. The property has also seen various infrastructure improvements over the years, including multiple sewer line repairs (most recently in 2017), garage door replacements, and front door replacements.

A significant environmental concern was noted in 2018 regarding potentially improper removal of lead paint and asbestos, though this issue was eventually addressed. More recent improvements include the installation of a 6.4 kW solar PV system in 2021. Current records indicate that both units at 324 and 326 Mississippi Street are operating as active short-term rentals, though there have been historical attempts to legalize certain modifications including exterior decks and additional bathrooms. The building's maintenance history suggests regular upkeep and modernization efforts by the current ownership, with most recent violations and complaints having been addressed through proper channels.
