1379-1381 16th Ave, San Francisco, CA 94122

The two-unit residential building at 1379-1381 16th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1926, currently owned by the Tong 1995 Revocable Trust T. The property's maintenance and improvement history shows a pattern of regular updates over several decades, with the most recent significant work being a $7,000 re-roofing project completed in 2007.

Prior improvements include comprehensive work in 1991-1992 when the building underwent substantial interior updates, including sheetrock installations, chimney and fireplace replacement, and insulation of walls and ceilings. The 1980s saw a series of improvements focused on window replacement and kitchen remodeling, including the installation of aluminum windows in both July and October 1985, followed by kitchen renovation work in 1988 that updated cabinets, countertops, and flooring.

While the building shows an established history of regular maintenance and upgrading, it's worth noting that the 1992 insulation project permit expired without recorded completion confirmation. However, no recent permits or significant issues have been recorded in the past 15 years, which may suggest either stable conditions or reduced renovation activity in recent times.
