171-175 Duboce Ave, San Francisco, CA 94103

The three-story multi-family residential building at 171-175 Duboce Avenue, constructed in 1907 and containing 6 units, completed its mandatory soft-story retrofit in 2017 (Tier 3) at a cost of $60,000, significantly improving its seismic safety. The building has undergone several substantial renovations, including a comprehensive kitchen and bathroom remodel in Unit 173A in 2015 ($25,000) that included modern electrical upgrades, plumbing improvements, and new appliances.

Between 2011 and 2018, the property addressed various maintenance issues, including exterior stair repairs, water damage remediation, and dry rot repairs to structural elements in 2013. Building inspections and violations from 2003 and 2013 noted several concerns including mold, stair repairs, weatherproofing issues, and lead paint safety, though all these violations were officially abated by February 2004. Recent maintenance and permit activity at the property has been limited primarily to street space permits between 2015-2019.

The building's systems received significant upgrades during the 2013-2015 period, including a 200-amp electrical service upgrade to the basement with individual meters for each unit. External areas around the building have experienced typical urban issues as evidenced by 311 calls, including parking violations, hazardous materials concerns, and general cleaning needs, though these are mostly related to street-level maintenance rather than building-specific problems. The most recent building-related activity was a routine safety inspection in 2009, with no significant violations recorded since the comprehensive remediation efforts of 2013-2014.
