691 5th Ave, San Francisco, CA 94118

The two-unit residential building at 691 5th Avenue in San Francisco's Inner Richmond neighborhood is a one-story flats and duplex structure built in 1908, currently owned by David C. and Barbara P. Thomson.

The building's maintenance history shows several significant improvements, including a complete reroofing project in 1988 and a renovation that included kitchen cabinet replacement, new countertops, bathroom retiling, and painting that same year. More recently, in 2013, there was a completed sewer replacement project, which represents the most recent significant infrastructure work on record. The property's incident report history primarily consists of external issues rather than building-specific problems.

There have been two recorded instances of driveway blocking in 2023 and 2022, both resulting in citations being issued to the offending vehicles. In 2017, there was a report of damaged trees (possibly related to vandalism), and a customer callback regarding electric service was logged and resolved in 2016. A defaced parking-related sign was reported and resolved in February 2023. While these incidents indicate typical urban neighborhood challenges, they do not suggest any structural or safety concerns with the building itself.
