1378-1380 16th Ave, San Francisco, CA 94122

The two-unit residential building at 1378-1380 16th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1927, currently owned by Allyn Thomas R & Denise H. The property has undergone several significant improvements over the past two decades, with the most recent major renovation completed in early 2023 involving substantial updates to the top unit, including the reconfiguration of the laundry room and addition of a full bathroom, complete with plumbing and electrical work for a tankless water heater and shower pan.

This $12,000 project represents the most recent investment in the building's infrastructure and amenities. Looking back through the building's permit history, 2002-2003 was a particularly active period, with multiple improvements including the construction of new two-level wooden decks at the rear ($15,000), a comprehensive kitchen remodel with electrical and gas upgrades ($20,000), and the installation of new kitchen cabinets, windows, and countertops ($14,320).

During this time, the electrical system was also upgraded to a new 200-amp service with three meters. More recently, there were two minor incidents recorded through 311 calls: one in early 2023 regarding a driveway blocking issue that could not be validated by responding officers, and another in early 2025 related to an encampment that was resolved through engagement by city services. The building's maintenance record suggests regular upkeep and modernization efforts by the current owners, with no recorded safety violations or significant resident complaints in recent years.
