The two-unit residential building at 1346-1348 Leavenworth Street, located in San Francisco's Nob Hill neighborhood, is a two-story flats and duplex structure built in 1909. The property has undergone significant improvements and renovations over the past decade, including the installation of solar panels, electrical upgrades, and plumbing renovations. Notably, in 2018, multiple permits were issued to obtain final inspections for various completed works, including plumbing and electrical upgrades. The building features solar PV installations completed in 2014, comprising two sets of modules (1.72 kW and 2.58 kW), along with a 300-amp electrical panel upgrade and laundry room improvements in 2013.

The property experienced serious construction-related issues in 2011, when complaints were filed regarding unsafe excavation that allegedly undermined the neighboring building's foundation, resulting in a foundation collapse and rodent concerns. These violations were eventually abated by May 2013. Other significant plumbing work includes bathroom renovations, radiant heat installation, and various sewer upgrades completed between 2011 and 2018. More recent history shows ongoing maintenance and support issues, with several 311 calls in 2023-2024 primarily related to street cleaning, parking violations, and tree maintenance.

A gas leak incident was also recorded, though no civilian injuries were reported. The building's maintenance history suggests active management, with most permits being properly renewed or completed, though some permits from 2014-2018 did expire. Recent external issues primarily involve street-level concerns such as parking violations and debris removal, with no significant building-specific complaints recorded in the past several years. The property has undergone various improvements to enhance sustainability and modernize systems, including multiple solar panel installations and electrical system upgrades. The historical construction issues in 2011 were addressed and resolved, with all subsequent permits being properly handled, though there were some construction-related complaints in 2012 regarding an unfinished work site.
