470 27th St, San Francisco, CA 94131

The two-story multi-family residential building at 470 27th Street in Noe Valley, owned by Uwe H. Dobers and Anne M.

Crowle, has a documented history dating back several decades with maintenance and infrastructure work primarily focused on structural and safety improvements. Most recently, in December 2017, the property underwent re-roofing work costing $15,000, marking the latest significant exterior maintenance on record. The building's foundation and structural integrity have been proactively addressed over the years, with foundation repairs completed in 2000 ($3,400), concrete slab installation in various rooms in 2005 ($3,200), and additional foundation work attempted in 1984, though that permit ultimately expired.

The property has experienced some infrastructure challenges, including a sewer system issue in September 2010 involving water discharge that was traced to a broken house pipe, and a public works complaint in March 2022 regarding misplaced tow-away signs that required intervention from city officials. The most recent incident related to the property was a sidewalk parking complaint in August 2024, though this was classified as unable to locate by responding officers. The building's permit history suggests regular maintenance and attention to structural elements, with no recent permits indicating urgent repairs or concerning safety issues.
