1143-1149 Guerrero St, San Francisco, CA 94110

The property at 1143-1149 Guerrero Street is a two-story, four-unit multi-family residential building located in Noe Valley, constructed in 1908 and currently owned by Luis Muela & Matilde Gomez. The building's most significant structural work was completed in early 2001, when earthquake upgrades were performed at the ground floor level at a cost of $18,000. More recent improvements include a sewer replacement from the property line to the curb completed in 2009.

The building has undergone several modifications and faced various compliance issues over its history, including a 2012 complaint regarding an unpermitted deck construction, and multiple fire safety violations in 2011 related to fire extinguisher maintenance. The property has an established history of maintenance and compliance actions, with resolved violations including handrail repairs and self-closing door requirements from 2001. Three planning records show attempts to address rear yard non-compliance issues, with an approved variance for reconstructing existing rear porches and stairs.

Recent municipal service requests primarily pertain to external maintenance issues such as tree maintenance and street cleaning, with the most recent being resolved cases from 2023 and 2024. While the building has had various maintenance and compliance issues over the years, all cited violations and complaints have been addressed and closed, indicating that current property management is responsive to regulatory requirements. The most recent significant structural work was completed over a decade ago, suggesting the building's major systems have remained stable since the 2001 earthquake retrofitting, though no recent building permits have been noted in the available records.
