1140-1142 Pacific Ave, San Francisco, CA 94133

The two-unit, two-story multi-family residential building at 1140-1142 Pacific Avenue in Nob Hill, owned by the Shui Yau Lee Sam Trust, has undergone several significant improvements since its construction in 1924. Most notably, in December 2022, the property received a $15,000 upgrade with the installation of 12 new aluminum wood-clad casement windows by Marvin, maintaining the original upper transom design. The building has also seen essential maintenance work, including rear stair repairs completed in January 2018 ($2,500), and more recently, the replacement of an existing Federal Pacific electrical panel in November 2024.

Historical records show earlier improvements such as a reroofing project in 2002, though that permit expired. The property has experienced various municipal service interactions over the years, with the most recent concerns being related to street cleaning and tree maintenance. In 2023, there were two encampment reports near the property that were unresolved upon inspection, while 2019-2020 saw reports of damaged and overgrown trees requiring attention.

Multiple 311 calls for street cleaning, including Christmas tree removal and a missed mechanical sweeping route, suggest regular urban maintenance requirements typical of the neighborhood. A unique planning record indicates a past modification to accommodate a sewing facility, though this appears to be a historical change now closed with CEQA clearance issued. The building's documented history shows consistent upkeep and modernization efforts by the current ownership, with particular focus on maintaining safety and improving energy efficiency through window and electrical system upgrades.
