3975 Cesar Chavez St, San Francisco, CA 94131

The two-unit multi-family residential building at 3975 Cesar Chavez St in Noe Valley, owned by Christian Keller Revocable Trust, has undergone significant renovations and infrastructure improvements over recent years. Built in 1900, this two-story flats and duplex structure has seen substantial work since 2022, including a major $554,000 renovation in late 2022 involving foundation replacement, window upgrades, door replacements, and deck modifications. Of particular note is the ongoing installation of a fire sprinkler system, with permits issued in 2024 showing the implementation of NFPA 13D and 24 systems, suggesting improved safety features being added to the building.

The property has also experienced recent HVAC upgrades, with permits showing the installation of multiple mini-split systems and forced air systems throughout the building in mid-2024. The building's history includes some concerning safety issues, most notably an active complaint from 2001 regarding collapsed rear stairs and an unpermitted deck construction issue. However, substantial efforts have been made to improve the building's infrastructure, including a significant electrical upgrade underway as of December 2024, doubling the service capacity from 200 amps to 400 amps.

Recent plumbing work has focused on comprehensive remodeling of two kitchens, three and a half bathrooms, and related infrastructure improvements. While there have been several parking-related complaints in the area and some issues with waste receptacles, these are generally routine neighborhood concerns and not specific to the building's condition. The extensive permit history, particularly in recent years, demonstrates ongoing investment in the property's maintenance and safety systems, with most recent permits focusing on fire safety and climate control improvements.
