229 Duncan St, San Francisco, CA 94131

The two-story multi-family residential building at 229 Duncan St in Noe Valley, owned by Howard & Cindy Tong, was constructed in 1953 and contains 4 units. The building's maintenance history includes a 2003 permit for installation of fiber cement siding shingles at a cost of $12,000, though this permit has since expired. A significant cluster of fire safety violations was documented in October 2010, including issues with fire proofing materials, fire extinguisher maintenance, smoke enclosure door hardware, combustible storage, and smoke detector installation—all of which were resolved by November 24, 2010 through a routine inspection process.

More recent concerns include a 2021 complaint about construction noise after hours, though this was related to the adjacent property at 227 Duncan. The building has undergone several routine inspections over the years, including in 1999, 2009, and the aforementioned 2010 inspection. Recent activity around the property (2020-2024) has primarily involved external issues such as parking violations, sidewalk blockages, and noise complaints, which are not directly related to the building's condition or safety systems.

The property's most recent safety-related incident was documented as a cooking fire confined to a container, with no civilian injuries reported. The building's documented history suggests that while there have been periods requiring attention to fire safety systems, these issues have generally been addressed through proper channels, and there have been no recent pattern of similar violations. The property has maintained its multi-family residential classification throughout its history.
