541-547 Guerrero St, San Francisco, CA 94110

The 12-unit, 3-story multi-family residential building at 541-547 Guerrero Street, constructed in 1911 and currently owned by Judy Librano Marroquin Revo, has experienced several significant maintenance and safety issues in recent years. Active violations from 2017 remain concerning fire safety, including blocked egresses, combustible storage, issues with fire sprinklers, and the need for carbon monoxide and smoke alarm updates.

Multiple complaints about hoarding in Unit 3 between 2009-2017 raised serious health and safety concerns, particularly regarding fire hazards and maintenance of common areas. The building underwent important structural improvements in 2010, including foundation work with anchor bolts and plywood installation valued at $20,000. Recent building maintenance activities include window replacement, electrical work, and plumbing updates in various units between 2014-2018, though some permits related to these repairs have since expired.

Multiple 311 calls in recent years (2020-2025) indicate ongoing issues with garbage/debris, graffiti, and sidewalk maintenance near the property. The building has experienced several false fire alarms and system activations between 2009-2021, though no civilian injuries were reported. While there have been some resolved complaints regarding hoarding and fire safety, the persistence of multiple active violations and historical maintenance challenges suggests ongoing oversight of building conditions is necessary.
