771-773 17th Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 771-773 17th Avenue in San Francisco's Central Richmond neighborhood is a two-story flats and duplex structure built in 1922, currently owned by Michael David Ivanoff.

The building's permit history shows minimal recent activity, with two street space permits issued in August 2008, each costing $1, though these permits are generally routine and have limited impact on the property itself.

The most significant modification on record was completed in 1992, when the basement area was converted into a utility and storage room with a bathroom, a $10,300 renovation that potentially improved the building's functionality. Given the age of the building and the relatively limited permit activity documented, it appears that major structural or system upgrades have not been undertaken in recent decades, though this cannot be definitively inferred from the permit records alone.
