4033-4035 25th St, San Francisco, CA 94114

The duplex at 4033-4035 25th Street in Noe Valley, owned by the Colin M Thurlow 2007 Trust, has undergone significant recent renovations and has a documented history of maintenance and improvements. Most notably, in September 2024, major upgrades were initiated including comprehensive renovations of one kitchen and two bathrooms in both units (4033 & 4035), installation of new appliances, interior finishes, relocation of a first-floor window, and replacement of a mechanical efficiency heat pump at an estimated cost of $110,000. This was followed by electrical rewiring of the entire two-unit building and plumbing upgrades including a complete remodel of kitchens and bathrooms, and replacement of main sewer and house trap.

A sewage backup incident was reported and resolved in August 2024, marking the most recent service issue. The property has undergone various improvements since its construction in 1900, including exterior siding repairs in 2023, window retrofitting in 2010, and significant plumbing work in 2016 including sewer system upgrades. Historical records show structural work in 1988 to address substandard framing of rear structures, though some earlier permits from the late 1980s and early 2000s have expired or were cancelled.

The building experienced sewer-related issues in 2014, 2017, and 2024, indicating some ongoing infrastructure challenges, though these have been addressed through repairs. A notable tenant buyout occurred in May 2023 for $50,000 involving one tenant at 4033 25th Street. The property has also been subject to several parking-related incidents in the vicinity, though these are not directly related to the building's condition or management.
