970-972 Guerrero St, San Francisco, CA 94110

The property at 970-972 Guerrero Street is a historic two-unit residential building located in the Eureka Valley/Dolores Heights neighborhood, constructed in 1885. The building has undergone several significant maintenance and restoration projects over the past two decades, with the most recent work focusing on restoring the portico to its original design as seen in historic photographs, a permit filed in November 2020.

Between 2018 and 2020, substantial improvements were made including rear deck strengthening, window restoration involving the replacement of failed dual glazing and repair of pocket doors, and carport slab repairs alongside replacement of the rear yard retaining wall and fence. Earlier maintenance included a complete reroofing project in 2005, along with foundation repairs that were properly documented and signed off. The building's electrical systems received upgrades in 2003 with a complete rewiring of kitchen, bath, and living room areas, including the installation of a 70-amp sub-panel, and in 2018 for outdoor deck lighting and GFCI receptacles.

While there have been several municipal service calls in the vicinity of the property from 2021 to 2024, most recent complaints have primarily been related to parking issues rather than building-specific concerns. The property has shown consistent maintenance attention from its current owners, Caitlin Spaan and Woodruff Wi, with all recorded permits showing either completed work or proper filing processes, though one planned restoration of columns and capitals was withdrawn in 2021. The building's maintenance history suggests regular upkeep of both structural and historical elements, with appropriate attention given to modern safety requirements such as electrical systems.
