668-670 2nd Ave, San Francisco, CA 94118

The Wong Family Trust owns this two-unit, two-story multi-family residential building, constructed in 1923 in San Francisco's Inner Richmond neighborhood. The property has undergone several significant upgrades in recent years, demonstrating active maintenance and modernization efforts by the owners. Most notably, in 2021, the building received substantial improvements including a complete electrical system upgrade with a new 100-amp dual meter main service panel, installation of a solar PV system (7.92 kW), and replacement of two furnaces.

In 2017, the kitchen was significantly remodeled, including new cabinets, countertops, appliances, and electrical systems. An important exterior improvement was completed in 2016 with the replacement of 20 aluminum-framed windows with composite-framed windows designed to match traditional wood details. The building's maintenance record shows attention to both interior and exterior improvements, though there have been some infrastructure issues noted in earlier years.

A sidewalk defect was reported in 2012 involving approximately 30 square feet of damaged pavement requiring attention. The property has experienced some recurring issues with street parking and abandoned vehicles in the vicinity, as evidenced by multiple 311 calls between 2013 and 2019, though these do not directly affect the building's condition or resident experience. The most recent building permits and improvements, particularly the solar installation and electrical upgrade, suggest the property is being maintained to modern standards, with recent improvements focused on energy efficiency and system upgrades.
