786-788 25th Ave, San Francisco, CA 94121

The two-unit residential building at 786-788 25th Avenue, located in San Francisco's Central Richmond neighborhood, is a two-story flats and duplex structure built in 1923 and currently owned by Peter Li and Mary Yee Chun Li.

The building's maintenance and repair history reveals a pattern of attention to structural integrity and basic modernization over several decades. Significant past work includes termite repairs in 1993, removal of dry rot and re-stuccoing of the front facade in 1989, and the installation of aluminum windows in 1983, all of which have been completed.

More recent maintenance activities include reroofing work that received an expired permit in 1998, and in 2010, permits were issued for street space scaffolding, though the specific purpose of this work was not detailed in the records. The building's age and permit history suggest regular maintenance attention, particularly to address common issues in older structures such as wood deterioration and weatherproofing, though the expiration of several permits raises some questions about whether these projects were fully completed or required follow-up work.
