906 Guerrero St, San Francisco, CA 94110

The building at 906 Guerrero Street is a three-story, two-unit multi-family residential structure built in 1885, currently owned by a marital trust. The property has undergone several significant modifications and faced various compliance issues over the years. Most notably, in 2004, the building was cited for having an illegal ground floor unit consisting of a kitchen, bedroom, bathroom, and living room constructed without proper permits, which led to a series of violation notices and abatement proceedings that were ultimately resolved in February 2013 through proper legalization work costing $57,960.

During this legalization process, a voluntary foundation upgrade was also completed in 2010 for $12,000, along with an electrical service upgrade to 200-amp service with Ufer ground, though this electrical permit has since expired. The building has experienced recurring maintenance and infrastructure issues, particularly with its surrounding environment. There have been multiple reports of tree-related problems affecting the property and public infrastructure between 2009 and 2023, including damaging property issues and sidewalk root lift problems.

Additionally, the property has faced periodic challenges with sidewalk cleanliness and street maintenance, as evidenced by multiple 311 calls regarding loose garbage, graffiti, and other general cleaning issues between 2008 and 2023. While these exterior maintenance issues have generally been addressed through proper channels, they highlight ongoing logistical challenges related to the building's surroundings. The property's most recent structural work appears to have resolved the major compliance issues from 2004, as indicated by the closure of all related violation cases.
