5501-5507 Mission St, San Francisco, CA 94112

The two-story multi-family residential building at 5501-5507 Mission Street, owned by Guido & Pierina Giosso Fmly, was constructed in 1927 and contains 11 units. The property has experienced several significant incidents, most notably a fire in Unit 6 in March 2020 that rendered the unit uninhabitable and resulted in temporary loss of heat and hot water for all units. This incident required various repairs including drywall, glass, cabinets, and flooring work, with associated permits filed totaling approximately $25,000.

The building underwent multiple safety improvements in the aftermath, including gas line testing (March 2020), electrical repairs (completed June 2021), and a final inspection in March 2023. Since the fire, there have been ongoing safety compliance issues, including two active violations from 2011 regarding fire extinguisher maintenance and lead hazard paint that remain unresolved. The property has a documented history of routine inspections and maintenance work, including a 2021 electrical service evaluation, plumbing upgrades, and various improvements to unit heating systems.

Historical records show past violations in 2000-2001 addressing fire safety concerns such as smoke detectors, fire extinguishers, and door requirements, all of which were abated. Recent years (2024-2025) have seen multiple 311 calls regarding various issues including encampments, debris, and parking violations in the vicinity of the property, though these are external to the building itself. A vacant store complaint was filed in May 2023 and remains active as of the latest records, and there was a sewage backup discharge issue reported in November 2024. The building's fire safety systems received attention following the 2020 incident, with corrections made to extinguisher placement and exit maintenance, though a sprinkler service violation was recorded in May 2021.
