818-820 33rd Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 818-820 33rd Avenue in the Outer Richmond neighborhood, owned by Alexy & Barbara Kondrasheff, has a documented history dating back to its construction in 1924. The two-story flats/duplex building has undergone several maintenance and improvement projects over the years, including a complete roof replacement in 1996, window installations in the living room area in 1984, and water heater replacement work in 2016.

A significant plumbing correction occurred in 2008, coinciding with a condo conversion process, though the specific nature of these improvements is not detailed in the records. More recent infrastructure issues have been documented with two separate sewer-related incidents: a flooding event in December 2016 and a sewage backup situation in May 2018, both of which were addressed and resolved by the Public Utilities Commission Sewer Operations department.

While these incidents indicate some historical challenges with the building's plumbing infrastructure, there have been no reported similar issues in the approximate five years since the last documented incident. The building's maintenance record shows periodic upkeep through various permits, though some, like the 1996 roofing permit and 2016 water heater work, are noted as expired in the current system.
