3969-3971 23rd St, San Francisco, CA 94114

The 2-unit residential building at 3969-3971 23rd Street in Noe Valley, owned by Jason S & Christy J Oliger, is a two-story flats and duplex structure built in 1900. The property has undergone several significant renovations over the years, with a major electrical upgrade completed in 2003-2005 that included complete rewiring of both units, service upgrades, and installation of new meters and panels.

In 2006, there were structural modifications including a new rear stair installation and changes to shear wall types. More recently, the building has seen sustainable improvements, with the installation of a solar panel system and battery backup (Tesla Powerwall) in late 2022. The property has experienced some maintenance and infrastructure challenges, including a sewage backup incident in October 2023 and a tree-related issue in February 2024.

There has been recurring concern with parking violations in the vicinity, with multiple reports of sidewalk parking and blocked driveways between 2023 and 2024. The building received two rear yard variances related to deck and stairs modifications in the mid-2000s, which were approved. The most recent building system improvements demonstrate a commitment to modernizing the property with renewable energy infrastructure, while the solar installation permits show completed work with proper final inspections obtained.
