481-483 Monterey Blvd, San Francisco, CA 94112

The property at 481-483 Monterey Blvd is a two-unit, two-story multi-family residential building located in the Sunnyside neighborhood, owned by Jeremy N. Gong and Catheri Yan, and was constructed in 1946. The building underwent significant renovations in 2006-2008, including a major rear extension valued at $200,000, followed by multiple revisions to the plans in subsequent months.

These revisions included changes to bathroom configurations, bedroom layouts, and the installation of various utilities including floor drains, sinks, and a furnace. During this renovation period, substantial electrical work was completed including a 200-amp service upgrade with three meters, installation of numerous electrical fixtures, and provisions for solar PV modules. The building's solar installation was completed in January 2010 with 10 roof-mounted panels and a 1.88 kW system.

The property has experienced several building-related issues throughout its history, including a complaint in 2009 regarding the rear extension's actual length exceeding approved dimensions, though this was subsequently abated. Recent maintenance issues have primarily involved exterior matters not directly related to the building's condition, such as street lighting (with two incidents in 2013, and one in 2016), graffiti on the building in 2017, and a parking enforcement issue in 2022. The building's systems appear to have been regularly updated and maintained, with the most recent significant work being a gas line extension in 2013 and the original solar installation in 2010.
