568 Mississippi St, San Francisco, CA 94107

The two-unit residential building at 568 Mississippi Street in Potrero Hill, owned by Richard Lockerbie Rockwell, has experienced several significant events since its construction in 1988. Most notably, there is an active building violation (opened November 2021) regarding unauthorized conversions, including a change of occupancy from R-3 to R-2, transformation of a garage storage room into a studio with kitchen and bathroom facilities, and conversion of the crawl space into a six-room area with similar amenities, all completed without proper permits or inspections.

In response to these violations, a permit was filed in January 2023 to create a compliant accessory dwelling unit (ADU) at the first floor, which includes installation of a new electrical meter, plumbing line, and mini-split system, with an estimated cost of $200,000. The building has undergone several legitimate improvements over the years, including window replacements in 2013 and bathroom/kitchen renovations in 2021. Recent maintenance work includes the replacement of a broken house trap in the sidewalk area (completed May 2024) and a gas water heater replacement in 2019.

Multiple 311 calls in 2024 indicate ongoing infrastructure issues in the vicinity, such as pavement defects and sidewalk concerns, though these are external to the building itself. The building's history also shows attention to parking enforcement matters, with several cases of blocked driveways reported between 2022 and 2024. The only recorded fire incident was a smoke detector malfunction, resulting in no civilian injuries.
