774-776 20th Ave, San Francisco, CA 94121

The two-unit residential building at 774-776 20th Avenue, owned by Herbert R Roche, is a two-story flats and duplex structure located in San Francisco's Central Richmond neighborhood, constructed in 1922. The building's documented history shows several noteworthy maintenance and infrastructure upgrades over the past two decades.

Most significantly, in December 2007, a comprehensive electrical system upgrade was completed, involving the installation of new electrical infrastructure including three meters and panels, as well as lighting and receptacle improvements, with work properly permitted under permit number E200712103766. An earlier maintenance project from 2001 (permit number 200102011141) involved reroofing work valued at $8,000, though this permit is shown as expired in the records. The property has experienced two documented service calls through the 311 system, neither of which appear to indicate serious ongoing issues.

In 2017, there was a resolved sewage backup incident involving a 4-inch vent line, which was addressed by PUC Sewer Operations. More recently, in March 2020, there was an enforcement response to a sidewalk parking violation, which was resolved by a responding officer. The building's infrastructure upgrades and relatively low number of service calls over this extended period suggests routine maintenance practices have been generally observed, though prospective tenants should note the age of the original structure and that some permitted work remains listed as expired in the records.
