4146-4150 25th St, San Francisco, CA 94114

The 4-unit, 2-story multi-family residential building at 4146-4150 25th Street in Noe Valley, currently owned by Klaus & Rosetta Zimmermann, was constructed in 1900 and has experienced various maintenance and safety issues over the past decades. The property has a documented history of deck maintenance problems, with multiple repairs due to dry rot between 2010 and 2016, including a deck post replacement in 2016 costing $850. The building underwent significant electrical improvements in recent years, including the installation of washer and dryer plugs in 2021, electrical panel changes in 2012, and comprehensive kitchen electrical upgrades in 2013.

Plumbing work included kitchen renovations in 2013 and the installation of two sprinkler heads in the garbage area. The building has experienced several concerning incidents related to water damage and infrastructure issues, particularly in 2012-2013, when multiple complaints were filed regarding toilet overflow problems, water leaks, and damaged ceilings. There were also multiple fire safety violations recorded between 2018 and 2024, including issues with alarm systems, sprinkler systems, and combustible materials, though many were subsequently corrected.

Recent 311 calls in 2024 have predominantly concerned garbage and debris management outside the building. Of particular note, there are recent fire code violations from November 2024 that warrant attention, though these were issued on the property address of 1220 Noe Street, which appears to be an administrative error as per the building's documented address. The property has maintained compliance with building codes through various repairs and updates, though the frequency of fire safety violations suggests ongoing maintenance challenges in this area.
