147 Caledonia St, San Francisco, CA 94103

The two-unit residential building at 147 Caledonia Street in the Inner Mission, owned by the O'deay Dan G Revocable Trust, was constructed in 1908 as a flats and duplex structure. The property has undergone some renovations, including a bathroom and kitchen remodel with new flooring in 1985, following sheet rock and paint work where electrical and plumbing installations were completed. Of particular concern is a serious security incident from 1996 when tenants reported multiple assaults at the poorly lit entrance, linked to defective lighting and switches, though this issue was officially abated in 1997.

The building has experienced recurring fire safety challenges over the years, with multiple complaints and violations recorded between 2015 and 2024. These include issues with alarm systems, blocked exits, and fire extinguisher maintenance, with violations documented in 2018 and 2021. While no civilian injuries have been reported in recent fire incidents, there have been several false alarms and cooking-related incidents recorded.

The most recent fire complaint in 2024 regarding extinguishers was found to have "No Merit". More recent concerns involve a sewage backup incident from December 2024 and multiple reports of human waste issues on the property perimeter in January 2025. The property has also seen significant street-related issues outside its boundaries, with numerous reports of garbage, debris, and abandoned vehicles in the immediate vicinity, though these are municipal rather than building-specific concerns.
