6140 California St, San Francisco, CA 94121

6140 California Street is a 2-story, 2-unit multi-family residential building constructed in 1925, currently owned by the Wilkens Family Revoc Tr. The property has undergone significant renovations and maintenance work over the past two decades, with the most substantial improvements occurring between 2011-2012, including a major remodel of the rear space, kitchen and bathroom updates, window replacements, and various plumbing and electrical upgrades.

Notable completed projects include a playroom addition in 2002, multiple bathroom remodels, and addressing water damage and dry rot issues in 2002 and 2008 respectively. Recent building maintenance has been minimal, with the last major permit work dating back to 2013 when windows were replaced. The property has experienced some recurring issues with garbage and debris on the street, with multiple reports between 2023-2024, though these appear to be street-related rather than building-specific.

Several parking enforcement calls regarding driveway blocking were made in 2023-2024, but officers were unable to locate the offending vehicles in each instance. Of particular note is a discontinued attempt in 2022-2023 to merge the two units into a single-family residence, which underwent Mandatory Discretionary Review but was ultimately withdrawn, leaving the current duplex configuration intact. The building's maintenance history shows regular updates to systems and structure, with particular attention paid to water damage issues in the early 2000s and comprehensive electrical work completed in 2012-2013.
