1167 Guerrero St, San Francisco, CA 94110

The two-unit residential building at 1167 Guerrero Street in Noe Valley is a century-old flats and duplex structure owned by Barbara Ann Dorer Trust. The property has undergone several significant improvements over the past two decades, with the most recent being a completed reroofing project in October 2024 costing $10,500.

Major renovations occurred in 2010 when the basement was converted from storage to a home office/den, including bathroom additions, concrete floor replacement, and stair modifications, accompanied by comprehensive upgrades to plumbing, electrical (including recess lighting installation), and the addition of solar power infrastructure with two sets of 7 roof-mounted solar PV modules. The building's maintenance history shows attention to basic infrastructure, with an earlier reroofing project completed in 2006 and various system upgrades, including a new furnace ductwork installation. The surrounding area has experienced recurring street maintenance challenges as evidenced by multiple 311 calls between 2019 and 2022, primarily related to unsanitary conditions on the street including reports of human or animal waste, medical waste, and loose garbage - all of which were investigated and resolved by the Department of Public Works.

Other external incidents included a fallen tree in 2018 and an abandoned vehicle report in 2019. The most recent incident near the property was a bicycle sharing operations complaint in early 2024, which was investigated and resolved by SFMTA. While the building itself shows consistent maintenance with no building-specific complaints or violations on record, the neighborhood's exterior environment has required regular attention to address various street maintenance issues.
