485-497 Guerrero St, San Francisco, CA 94110

The two-story multi-family residential building at 485-497 Guerrero Street, owned by T & A Drolapas & Sons LP, has a documented history of drainage and weather-related maintenance issues spanning several decades. The most recent significant incident occurred in October 2024, involving a sewage backup discharge from a side sewer vent, which was subsequently resolved. Between 2006 and 2011, the building experienced multiple complaints regarding roof drainage problems, including inadequate drainage systems, overflow issues, and flooding concerns affecting both the property and neighboring buildings.

Historical records show various maintenance work completed in the 1980s, including kitchen remodeling, dry rot repairs, and reroofing, though some permits from this period are now expired. More recent maintenance activities include a gas line installation for dryers in 2011, with records showing this work was completed. The property has seen an increase in infrastructure-related service calls in 2024, with multiple reports regarding garbage, debris, and abandoned vehicles in the vicinity, though most of these cases have been resolved or closed.

Notably, there was one open case regarding garbage and debris from September 2024 that remains unresolved as of the report's creation date. While the building's historical issues primarily revolved around water drainage concerns, the most recent service calls suggest a shift in focus towards external property management matters in the surrounding area. The building's documented history indicates periodic maintenance work has been performed to address various building needs, though the frequency and nature of these repairs suggest ongoing attention to infrastructure upkeep may be required.
