172 8th Ave, San Francisco, CA 94118

The two-unit residential building at 172 8th Avenue, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1911 and currently owned by the Gee May S Revocable Trust T.

The building has undergone several significant maintenance and repair projects over the past three decades, most recently receiving a complete reroofing in March 2023 at a cost of $19,700. A notable incident occurred in 2014 when the property experienced foundation concerns due to over-excavation at an adjacent property (176 8th Avenue), which resulted in a violation and required geo grout injection work costing $5,000 to stabilize the south property line's foundation; this violation was ultimately resolved by August 2015.

Other improvements include window replacements in 2005 (upgrading to wood composite with three new windows) and an earlier roofing project in 1994, though the latter permit expired. The building has not experienced any significant safety violations since 2015, and while there have been two 311 calls in recent years (one for a defaced sign in 2023 and another for street cleaning in 2021), neither of these issues directly impacted the building's condition or habitability.
