1970-1972 Jefferson St, San Francisco, CA 94123

The property at 1970-1972 Jefferson St is a two-story, three-unit multi-family residential building located in the Marina neighborhood, owned by O'Keeffe Owen and constructed in 1946. The building has undergone several significant improvements and maintenance work over the past two decades, with the most recent major updates including the replacement of front French door units on the 2nd and 3rd floors in 2019 ($6,000), the installation of four skylights in 2018, and extensive renovations to enlarge a third-floor bedroom in 2016 ($75,000).

The property has demonstrated regular maintenance of essential systems, with multiple water heater replacements (most recently in 2020), installation of gas fireplaces (2019), and electrical upgrades including a remodel of the third-floor bedroom suite in 2018. The building's history shows some challenges in the early 2000s, particularly a cluster of housing code violations documented in January 2003 that included issues with ceilings, walls, windows, lighting, and drainage pipes, though these were all addressed by March 2003.

There were also concerns about construction work without proper permits in 2018, and an expired permit issue in 2008, both of which were resolved. The plumbing and electrical systems have received consistent attention, with multiple permits issued for various installations and replacements, including a 200-amp service upgrade with two meters in 2003. Recent maintenance patterns suggest active management of the property's upkeep, with completed permits for both building improvements and system upgrades continuing through 2020.
