957-961 Oak St, San Francisco, CA 94117

The three-story multi-family residential building at 957-961 Oak Street in Hayes Valley, managed by Wimmer Properties LLC, was constructed in 1900 and contains 5 units. The building is currently listed as non-compliant with the mandatory Soft Story Retrofit Program (Tier 3) as of October 2019, with an active violation regarding failure to complete required seismic retrofit work. This is particularly concerning given San Francisco's earthquake risk. The property has undergone several significant improvements over the past decade, including seismic retrofit work (approved in 2017 with an estimated cost of $60,000), bathroom and kitchen remodels in multiple units between 2014-2015, and most recently, a reroofing project permitted in September 2024 with an estimated cost of $15,000.

The building has experienced various maintenance issues, as documented in housing complaints, including a 2010 complaint citing mold, heating issues, and electrical problems, though these were marked as not active by 2012. Multiple plumbing and electrical upgrades have been completed, including the installation of gas fireplaces and the addition of energy-efficient lighting throughout the building. The property has a notable history of building violations, particularly related to fire safety and building maintenance, with several active and past violations documented between 2007-2019. These include issues with fire extinguishers, combustible storage, gas shutoff tools, and security requirements, most of which were addressed by February 2022.

The building has experienced various exterior maintenance issues over the years, including problems with window leaks and paving repairs, though these were resolved promptly. Recent activity at the property has primarily involved routine maintenance and external issues such as graffiti removal and noise complaints. The most recent maintenance work on record, the reroofing project in 2024, suggests ongoing investment in building maintenance, though the outstanding Soft Story compliance issue remains a significant concern. The building has also undergone regular routine inspections throughout its history, with most issues being addressed promptly, though some violations took considerable time to resolve, particularly those documented in 2019.
