1561-1563 Mason St, San Francisco, CA 94133

The two-unit residential property at 1561-1563 Mason Street in Russian Hill, owned by Rollin Wing Wong, is a two-story flats and duplex building constructed in 1907. The building has undergone several significant improvements over the past two decades, with the most recent major work including a complete reroofing project in 2022 costing $14,900 and a mechanical upgrade in 2021 involving replacement of the house trap.

The building demonstrated substantial modernization efforts between 2009-2010, including the conversion of a rear basement area into living space (adding a bedroom, study, bath, and storage), replacement of 23 windows, kitchen cabinet upgrades, exterior painting, and the addition of a half bathroom in the basement. Prior structural improvements include a roofing project in 2000, foundation reinforcement work in 1998, and various safety upgrades such as the installation of smoke detectors.

The property has experienced numerous parking-related issues in the immediate vicinity during 2024, with multiple citations issued for blocked driveways (seven confirmed citations between June and November 2024), suggesting an ongoing challenge with parking management in the area. Two reports of abandoned vehicles were filed in May 2024, with one still showing as open in the system as of the latest update. While these parking issues may not directly impact the building's internal conditions, they indicate potential challenges with street parking availability and enforcement in the neighborhood.
