330-334 Guerrero St, San Francisco, CA 94103

The three-story, five-unit multi-family residential building at 330-334 Guerrero Street, built in 1911 and owned by Kong Juan C & Kempner Donna, has undergone several significant improvements in recent years. Most notably, in 2018, the building completed a $92,000 soft-story retrofit of the storage level, including the installation of new shear walls, anchor bolts, and grade beams, which brought the property into compliance with seismic safety requirements. In 2019, electrical infrastructure was upgraded with the replacement of six load centers, and two street space permits were issued in 2019 and 2005, respectively.

The building has a history of addressing safety concerns promptly. In 2003, following a routine inspection, multiple violations were documented regarding fire safety and security, including issues with smoke detectors and fire escape ladders, all of which were resolved within weeks by October 3, 2003. Earlier concerns in 2001 regarding electrical billing discrepancies and lead paint were also addressed. The building's maintenance history shows attention to structural elements, with records of reroofing work in 1994 and 2003, and stucco replacement in 1985.

Recent activity around the property has primarily involved exterior maintenance and urban management issues, with multiple 311 calls in 2024 regarding abandoned appliances and debris. The building's sidewalk area received attention in 2021 for a lifted sidewalk issue, which was addressed by utility maintenance. A tenant buyout was executed at the related address of 332 Guerrero Street in December 2020, with one tenant receiving $10,000. The property's soft-story retrofit work has been completed and certified, with the building assigned to Tier 4 status, indicating compliance with current seismic regulations.
