5243-5247 Mission St, San Francisco, CA 94112

The property at 5243-5247 Mission Street is a three-story multi-family residential building with commercial storefront, constructed in 1942 and owned by Alice Lian Fang Lim, located in the Croker Amazon neighborhood. The building contains three units, including one currently under investigation for being an unauthorized dwelling unit, as evidenced by a November 2023 violation complaint that cited multiple safety code violations including lack of required smoke detectors, inadequate egress, unapproved plumbing and wiring, and insufficient light and ventilation. The illegal unit, comprising a bedroom, kitchen, and bathroom, is reportedly located on the ground floor behind the commercial storefront.

Recent permit activity includes a December 2024 application to legalize the 366-square-foot unit, though this is currently in triage status. The building has a history of compliance issues, with previous complaints about unauthorized residential use of commercial space filed in 2014 and 2016, and three vacant storefront complaints between 2019-2023. The property's maintenance history includes several significant renovations, such as a 2007 remodel of the existing store into a retail office (with accompanying electrical and plumbing improvements) and various infrastructure works including a bathroom project in 1998, retaining wall construction in 1997, and reroofing in 1995.

The building has experienced recurring issues with exterior maintenance, as demonstrated by multiple 311 calls regarding graffiti (with several recent incidents in 2022-2023) and sidewalk cleaning needs. A tenant buyout occurred in March 2024 for $45,000 involving one tenant, suggesting recent tenant turnover. The property has been subject to various planning inspections and notices, including an unauthorized commercial use investigation, though some cases were closed with no violations found.
