373 Upper Ter, San Francisco, CA 94117

373 Upper Terrace is a two-story, three-unit multi-family residential building constructed in 1966, located in the Buena Vista Park neighborhood and currently owned by the Bertram S Koel Survivor's Trust. The property has undergone several significant improvements over the past three decades, with the most recent substantial work occurring in late 2024.

Current permitted projects include a partial interior remodel and the reversion of conditioned space into an exterior balcony (valued at $150,000), along with updates to Unit #2 involving door replacements and bathroom modifications (costing $15,000). Historically, major works have included reroofing projects in 1996 and 2013, window replacements in 1984, and a horizontal addition attempt in 1989 (permit expired). The building experienced multiple safety and maintenance violations in 2004, including issues with open viewers, fire extinguisher maintenance, and gas utility shutoff tools, though all of these violations were resolved by July 2004.

More recent history shows primarily minor external issues, with 311 calls concerning sidewalk defects (2022), illegal parking (2024), and other neighborhood matters, none of which indicate serious building concerns. The property has maintained active compliance with building regulations since the 2004 violations were addressed, and current planning records indicate a proposed improvement project under review that aims to revert previously modified space back to its original design while improving compliance with rear setback requirements. This project, designed by Klopf Architecture, includes window/door replacements, new skylights, and potential wood siding replacement.
