1671-1673 9th Ave, San Francisco, CA 94122

The two-unit residential building at 1671-1673 9th Avenue in the Inner Sunset neighborhood is a two-story flats and duplex structure built in 1976, currently owned by the John & Connie Loo 2002 Trust. The building's maintenance record shows several permitted improvements over the years, including a street space permit issued in 2019, an electrical upgrade with underground service conversion and installation of 200A service with two meters completed in 2003, and an expired reroofing permit from 1999.

Historical records indicate compliance with an inspection report in 1984. The property has experienced various service requests and incidents in recent years, though none appear to be directly related to the building's structural integrity or safety systems.

Most recent incidents include a parking enforcement call in January 2023, reports of overgrown vegetation on the curb in September 2022, and two animal control-related calls in 2021 and 2016. Other incidents involved parking violations (U-Haul on sidewalk in April 2018), a temporary sign issue in August 2018, and a streetlight outage resolved by PG&E in November 2013. The building's permit history suggests regular maintenance and upgrading of essential services, particularly noting the significant electrical infrastructure improvement in 2003.
