691-693 6th Ave, San Francisco, CA 94118

The two-unit residential building at 691-693 6th Avenue in San Francisco's Inner Richmond neighborhood is a two-story flats and duplex structure built in 1907 and currently owned by the Mary L Ng Living Trust. The property's documented history shows several significant improvements and maintenance work over the past four decades, with the most substantial renovation occurring in 2003 when unit 693 received a kitchen remodel and new full bathroom installation, accompanied by corresponding electrical work (3 lights, 3 switches, 7 receptacles, 3 circuits) at a cost of $15,000.

Earlier improvements include the installation of six windows in 1985, reroofing in 1991, and street space work in 2009. The building's records show minimal issues with only one documented fire incident - a false alarm or call in 700 - and a minor series of maintenance and public space matters, including a 2011 street cleaning issue with loose garbage, a 2013 non-offensive graffiti incident on a pole, and a 2009 loose street sign that required servicing.

The most recent interaction with city services was a mailing request to the Rent Board for fee housing inventory information in October 2023, which has been successfully resolved. While the property has undergone various updates over the years, there have been no significant safety violations or concerning incidents recorded.
