3766-3768 20th St, San Francisco, CA 94110

The two-unit residential building at 3766-3768 20th Street in Mission Dolores, owned by the David C Fleming Revocable Living Trust, was constructed in 1907 and is classified as a Flats & Duplex structure with two stories. The property has undergone several significant infrastructure improvements over the past decades, including a complete roof replacement in 2010 costing $7,880, multiple water-related repairs between 2006-2023 (including water line repairs and water heater updates), and conversion to underground electrical service with two meters in 2004.

A horizontal addition was completed in 1995, and the building experienced some plumbing code issues in 2006 regarding unauthorized copper pipe installation, though this was resolved by June 2007. Recent maintenance activity includes a gas line installation in April 2023 and water line repairs in June 2017.

The building has had three notable housing complaints, though none are currently active: one in 2011 regarding peeling exterior paint, one in 2006 concerning unauthorized basement work, and one in 2003 about unpermitted first floor and basement work. While the property's infrastructure appears to be maintained adequately based on permit activity, the surrounding area has experienced recurring parking enforcement issues, with multiple citations issued between 2020-2024 for driveway blocking. The most recent infrastructure work appears to be limited to the 2023 gas line installation, suggesting the building systems may be relatively stable, though there have been periodic maintenance needs related to water and electrical systems as evidenced by the various permits and repairs over the years.
