1541 Mason St, San Francisco, CA 94133

The two-unit residential building at 1541 Mason Street in Russian Hill, owned by George Huie and Sharon Yu, is a two-story flats and duplex structure built in 1947. The building has undergone several significant modifications and maintenance work over its lifetime, most notably an expansion in 1984 that added an additional floor and enlarged the existing unit.

In 1990, repair work was completed to address dry rot issues around the patio doors and the bottom of the parapet wall. More recently, there was reroofing work permitted in 1996, though this permit has since expired.

The most pressing current issue facing the property involves recurring parking enforcement matters, with multiple reports of driveway blocking incidents between June 2024 and January 2025. During this six-month period, there were ten documented cases of blocked driveways reported to the MTA Parking Enforcement, of which seven resulted in citations being issued and two cases were unresolved when officers were unable to locate the offending vehicles. While these incidents relate to public street parking rather than building infrastructure or maintenance issues, the frequency of these occurrences suggests an ongoing challenge with vehicle access to the property.
