4037-4039 25th St, San Francisco, CA 94114

The property at 4037-4039 25th Street is a 2-unit, 4-story multi-family residential building located in Noe Valley, owned by Christopher L. Wahlgren and constructed in 1900.

The building has undergone significant renovations and maintenance work over the past two decades, with particular attention to addressing dry rot issues. Major improvements include comprehensive interior renovations in both units in 2017 (valued at $30,000), partial foundation replacement in 2014, and window replacements in 2013. The property has seen extensive bathroom and kitchen remodels in both units, with work completed in 2009-2010 costing over $50,000, including plumbing updates for multiple bathrooms and kitchens, electrical rewiring, and installation of new features like a gas fireplace.

The building has faced some structural challenges, particularly in 2010 when issues with the penthouse structure led to complaints about unauthorized work and concerns about asbestos debris, though these were promptly addressed and no violations were recorded. More recently, there have been two sewage-related incidents reported in 2023-2024, including a back-up discharge in December 2024, and parking enforcement issues in the vicinity, particularly regarding sidewalk parking violations, though none of these incidents directly impacted the building's structural integrity or resident safety. The property's maintenance record shows regular upkeep and modernization efforts, with most permits marked as complete, though there was one permit filed in 2010 for framing replacement due to dry rot and termite damage that had a valuation of $0.
