681-683 Commercial St, San Francisco, CA 94111

The Chung Family Trust property at 681-683 Commercial Street is a two-story, mixed-use building constructed in 1908, containing two residential units and ground-floor commercial space, located in San Francisco's Financial District North. The building underwent significant improvements in 2018-2019, including a major ground floor renovation transforming the space from office to limited restaurant use, with associated plumbing and electrical upgrades costing approximately $120,000.

This work included the installation of new plumbing fixtures, flooring, service counter, and electrical systems, including a panel replacement and new lighting. The property has maintained compliance with safety standards, having received a seismic retrofit in 1995, and recent heating system upgrades with furnace and HVAC replacements in 2019. The building's maintenance history shows regular attention to basic infrastructure, including roof work in 1999, basement slab replacement in 1997, and sidewalk improvements in 1996.

While there have been recent 311 calls regarding the exterior environment (2024-2025), including reports of sidewalk cleaning needs and a damaged fire police callbox, these incidents are primarily related to street maintenance rather than building safety or habitability. A carbon monoxide detector was activated at some point, but no carbon monoxide was detected and there were no civilian injuries reported. The property's commercial space has been properly permitted for limited restaurant use, operating under the name "Neutral," and all significant building permits have been marked as complete, indicating proper closure of work associated with the permits.
