1854-1856 48th Ave, San Francisco, CA 94122

The King Ly Trust-owned duplex at 1854-1856 48th Avenue in San Francisco's Outer Sunset neighborhood is a two-story, multi-family residential building constructed in 1946. The property has undergone several significant renovations and improvements over the past decades, with the most substantial work occurring between 2005-2008 when a major rear extension project worth $230,000 was initiated, though it's noted that the permit for this work ultimately expired.

During the same period, the building received comprehensive infrastructure upgrades, including the installation of two full bathrooms (2007), new water lines, electrical improvements adding multiple circuits, lights, and outlets (2007), and sewer line extensions (2007). Prior improvements include the partitioning of the ground floor and recreation room modifications in 2003, and window replacements in 1999 when four front windows were changed to new units of the same size. The building's maintenance and safety record shows minimal concerns, with only one documented fire-related incident involving a light ballast breakdown, which resulted in no civilian injuries.

Recent 311 calls related to the property have been primarily external matters, such as street lighting inquiries in 2013 and a municipal service feedback in 2024, neither of which directly impacted the building's condition or safety. All significant building permits from 2007, including plumbing and electrical work, have been properly completed, and while some earlier permits from 2000 and 2005 expired, these appear to be from previous or unrelated projects. The property's documented history suggests regular maintenance and upgrading of essential systems, with particular attention paid to bathroom facilities, electrical systems, and structural improvements during the 2000s.
