735-737 Capp St, San Francisco, CA 94110

The two-unit multi-family residential building at 735-737 Capp St in San Francisco's Inner Mission neighborhood, owned by Robert H Ostertag, was constructed in 1900 and has undergone several significant improvements over the years. The property has received substantial upgrades between 2023-2024, including major electrical work with two permits issued for 200A service upgrades and electrifying existing gas loads, as well as improvements in 2024 for various appliances and convenience receptacles.

Solar energy has been a focus since 2003, with the installation of a 3.2 kW system, and a more recent solar photovoltaic system expected to be installed by the end of 2024. The building underwent important safety improvements in the late 1990s, including voluntary seismic upgrades and hot water heater relocations in 1998.

Historical records from 1996 show two complaints about possible illegal units with inadequate living conditions, though these cases were abated in 1997 and the building has since undergone numerous permitted remodels, including kitchen and bathroom renovations. Recent maintenance issues of note include multiple sewage backup incidents in 2023-2024, and while there have been several fire alarm activations, none resulted in actual fires or injuries. The building has experienced recurring issues with street maintenance as evidenced by multiple 311 calls for debris and cleaning needs, particularly in 2024, and a combustible materials complaint that was promptly corrected in 2018.
