481-483 Guerrero St, San Francisco, CA 94110

The property at 481-483 Guerrero Street is a 2-story, 4-unit multi-family residential building with ground-floor commercial space, constructed in 1907 and currently owned by the Sara M Liang Trust. The building has undergone several significant changes in occupancy and commercial use over the past two decades, with the most recent permit filed in May 2023 indicating a change of occupancy from barbershop to cafe, along with the addition of a security gate.

The commercial space has experienced multiple transitions, originally operating as a retail art gallery, then a coffee shop/cafe, and at one point being converted to a full-service restaurant, although this last change generated complaints about ventilation installation and noise issues. The building's history shows attention to accessibility and safety improvements, including ADA bathroom modifications and electrical upgrades in 2012, though some permits from that period were either revoked or expired. In 2003, the building faced multiple fire safety violations related to emergency egress, fire escape maintenance, and combustible storage, all of which were abated by October 2003.

The property has undergone regular maintenance work, including reroofing in 2007, and plumbing and electrical improvements in 2012. Several complaints were filed in 2012 regarding unauthorized construction work affecting neighboring units' windows and light wells, which were subsequently resolved. The building has maintained an active history of both planned improvements and regulatory compliance issues, with many older violations and complaints having been resolved through proper channels.
