1130-1134 Mason St, San Francisco, CA 94108

The three-story multi-family residential building at 1130-1134 Mason Street in Nob Hill, owned by Woo Hing Revocable Trust, was constructed in 1908 and contains 4 units. The property has undergone very limited documented improvements, with a single permit from 1991 showing the installation of 9 aluminum windows in existing frames, though this permit shows as expired.

The building has been subject to multiple routine housing inspections, with the most recent occurring in May 2016. During this 2016 inspection, several safety-related violations were identified, including the need for carbon monoxide and smoke alarm affidavits, fire extinguisher date tags, manual releases for sleeping room security bars, and structural maintenance compliance - though all these violations were marked as abated by June 6, 2016. Previous routine inspections in 2009 and 2000 also revealed various safety concerns that required attention, including fire extinguisher maintenance, gas meter instructions, and egress obstructions, all of which were subsequently resolved.

More recently, there have been no building-specific violations or complaints on record since 2016. The only relevant incidents in the area have been minor street-related issues, including reports of abandoned vehicles and general street cleaning needs between 2015 and 2022, though these are external to the building itself and do not directly impact resident safety or building conditions. The property's historical record suggests a pattern of addressing violations when identified, with all noted issues being resolved within reasonable timeframes, and there have been no documented recurring safety concerns in the past seven years.
