158-160 17th Ave, San Francisco, CA 94118

The two-unit, two-story residential building at 158-160 17th Avenue, constructed in 1915, has undergone several significant improvements over the past decades. The property has received multiple renovations to maintain and upgrade its facilities, including a major modernization of unit 160 in 2009 that included bathroom and kitchen updates with new cabinets, plumbing, and electrical work (though this permit ultimately expired).

Earlier improvements included a kitchen remodel in 2004, a complete reroof in 2005, and important structural work including foundation bolting and sunroom footing repairs in the late 1980s. More recent maintenance has focused on infrastructure, with a sewer replacement completed in 2009 and a street space permit issued in 2019.

The building's plumbing and electrical systems have seen systematic upgrades, including a 60-amp subpanel installation and comprehensive electrical work during the 2004 kitchen and laundry remodel. While the property has experienced some service-related incidents in the surrounding area (e.g., a sewage backup in 2020, human/animal waste issues in 2020, and general cleaning needs in 2021), these were primarily street-level concerns rather than building-specific problems. The most recent maintenance activities, including permit renewals for plumbing and electrical work in 2012, suggest ongoing attention to building systems, though it should be noted that some earlier permits from 2009 and 2004 were filed as expired rather than completed.
