1435-1437 Dolores St, San Francisco, CA 94110

The two-family residential building at 1435-1437 Dolores Street in Noe Valley, owned by Manuel M & Thi Lam Sierra R, is a two-story flats and duplex structure dating back to 1908. The property has undergone several significant improvements over the past two decades, with the most recent major work being the installation of a 4.1 kW solar PV system in April 2023 and the replacement of a 39-gallon gas water heater in February 2024. The building has seen consistent maintenance and upgrades, including reroofing projects in 2002 and 2017, multiple bathroom renovations (2014), window replacements, and insulation improvements (2013).

More substantial structural work was completed in 2003 with seismic retrofitting and foundation bolting improvements. The property has maintained good overall condition, though there have been a couple of notable issues requiring attention. In 2017, there was a complaint regarding improper lead paint containment, and in 2012, there was a complaint about unauthorized siding replacement using different materials on this historical building.

Both issues were investigated and marked as "Not Active." The building's infrastructure has been systematically upgraded, including heating system improvements (furnace replacement and ductwork in 2013) and electrical system enhancements (new subpanel for solar, underground electrical service in 2004). Planning records indicate proposed but unbuilt improvements for additional units and deck construction, with one deck-related proposal being approved. The property's maintenance history shows regular upkeep and modernization efforts, with permits for each significant improvement properly filed and completed according to records.
