3159 Mission St, San Francisco, CA 94110

The three-story mixed-use building at 3159 Mission Street in Bernal Heights, owned by Michael & Valerie Hough, was constructed in 1900 and contains three residential units plus ground-floor commercial space. The property has undergone several significant transformations over the past two decades, including a change from medical office to massage establishment in 2015 (currently operating as Balance Traditional Thai Massage), and a previous conversion from real estate office to medical service in 2013.

The building has seen important infrastructure improvements, including a voluntary partial foundation upgrade and accessibility improvements to the rear toilet room in 2011, along with comprehensive electrical work completed in 2013 that included 10 new circuits, lighting installations, and receptacle additions. Historical maintenance records reveal past challenges with moisture and structural issues, including a 2012 mold complaint in a closet (emerging again after treatment), and more serious safety concerns documented in a 1998 complaint regarding heat failure, broken windows, unstable back stairs, and ceiling leaks, which were eventually resolved by 1999.

The building has undergone various repairs including dry rot remediation in 1999, bathroom and kitchen repairs, bathroom remodeling in 2011, and electrical rewiring, though some permits from the 1990s are listed as expired. Recent activity at the property primarily consists of external maintenance issues, as evidenced by multiple 311 calls in 2024 regarding sidewalk garbage and debris, though these appear to be related to street cleaning rather than building-specific problems. The property's permit history shows regular maintenance and upgrades over the years, with no recent building code violations or major structural concerns on record.
