135 18th Ave, San Francisco, CA 94121

The three-unit multi-family residential building at 135 18th Avenue, owned by the Low Gene K & Hannah S Trust, has a documented history spanning over two decades, with the most recent significant event being a comprehensive re-roofing project completed in October 2024 costing $30,000. The property experienced a notable fire incident in October 2021 that required repairs to two floor joints and subfloor work in Unit A, along with subsequent upgrades to the unit's systems including a new furnace installation, gas line addition, and electrical subpanel upgrade.

The building's electrical infrastructure has seen improvements over the years, with a major upgrade from 100 to 200 amp service completed in 2005. Of particular concern is the recent pattern of sewage-related issues, with multiple incidents reported through 311 calls in late 2024, suggesting ongoing plumbing system challenges.

The property's maintenance history includes various works such as street space usage (2020), and a complaint in 2001 regarding unpermitted remodeling was filed and subsequently abated. The building's exterior envelope has required attention over time, as demonstrated by the recent re-roofing work, which replaced existing materials in-kind. The property has experienced some structural and accessibility issues, including a 2024 report of a difficult-to-open restroom door following renovations, though this was subsequently addressed according to records.
