43 Pomona St, San Francisco, CA 94124

The two-unit residential building at 43 Pomona St in Bayview, owned by Qin Guo Ming, has undergone several significant modifications since its construction in 1910. Most notably, in 2015, a staircase was added to connect the second floor to an attic space, along with the construction of four dormers, representing a $30,000 improvement to the property.

The building has also seen important infrastructure upgrades, including the installation of a 6.3 kW solar PV system with 20 roof-mounted modules in December 2016, and replacement of the existing electrical service to 100A capacity, both of which have been completed. A plumbing issue arose in January 2007 when a water heater was installed incorrectly, causing flue gases to flow into a garage area inside the building; this safety violation was promptly addressed and abated by July 2007. The property has experienced some ongoing quality-of-life issues in recent years, particularly in 2023-2025, with multiple reports of dog barking noise (January and September 2023) and convenience concerns including illegal parking and garbage/debris issues.

A significant infrastructure incident occurred in September 2024, involving a broken house pipe that required attention. The building's systems have been regularly updated, as evidenced by the 2007 water heater flue installation and subsequent electrical and solar improvements, suggesting ongoing maintenance and infrastructure investment by the owner. The most recent building modifications, including the attic staircase and dormers, were documented in planning records and appear to have been completed according to approved plans.
