1102-1120 Mason St, San Francisco, CA 94108
The 5-unit, 2-story apartment building at 1102-1120 Mason Street in Nob Hill, owned by Alice Poon Harding, was constructed in 1909 and has undergone several significant safety improvements over the years. Most notably, the building completed a mandatory soft-story retrofit in 2017-2018 (Tier 3) to improve seismic safety, costing $55,000, with additional structural revisions honored at $5,000. The building has maintained compliance with fire safety regulations, having resolved violations from 2000-2009 that included requirements for smoke detectors, fire extinguishers, and security features.
A reroofing project was completed in 2011 at a cost of $18,700. Recent history shows routine inspections by Housing Inspection Services, with the most recent routine inspection recorded in 2016. The building's recent maintenance and safety record appears generally compliant, with the most common recent issues reported through 311 calls involving external matters such as graffiti and sidewalk cleaning (2024).
Two encampment reports and one parking complaint were logged in 2024, though these were not directly related to building conditions. The property experienced two fire-related incidents - one false alarm and one smoke detector malfunction - with no civilian injuries reported in either case. The building's systems have been upgraded to include wireless equipment for AT&T Mobility, representing modern infrastructure improvements. Current maintenance issues have primarily involved external factors such as street cleaning needs and mailbox maintenance, with most cases being promptly resolved by appropriate city services.
