1142 Jackson St, San Francisco, CA 94133

The 6-unit, 3-story multi-family residential building at 1142 Jackson Street in Nob Hill, built in 1909 and owned by Jerry & Christina Cheng Family, has undergone substantial improvements in recent years, most notably completing its mandatory soft-story seismic retrofit in 2014 and maintaining compliance with fire safety requirements through a $10,000 fire alarm system upgrade in 2019 that included low frequency sounders in sleeping areas. The building has seen significant unit improvements, including a 2017 renovation of Unit 3 that involved kitchen and bathroom modifications, plus a major 2008-2009 overhaul of multiple units featuring new central heating systems, electrical upgrades, and appliance installations.

The property experienced several building violations in 2008 related to heat, sanitation, and security requirements, all of which were abated by February 2009. There were also complaints regarding unauthorized construction work in 2015 and heating system modifications in 2008, though these issues were subsequently resolved.

Recent records from 2024 show recurring reports of abandoned debris and furniture near the property, though these are street-related issues rather than building-specific concerns. All historical fire incidents recorded have been minor, consisting of alarm activations and a malfunctioning smoke detector, with no civilian injuries reported. The building demonstrates a pattern of regular maintenance and improvements, with all major safety and structural requirements having been addressed through completed permits and inspections.
