1453-1457 Mason St, San Francisco, CA 94133

This three-unit residential building at 1453-1457 Mason Street in Nob Hill, owned by Shiu & Pun Po Ng 1998 Revoc, was constructed in 1905 and consists of three stories classified as Flats & Duplex. The building has undergone several maintenance and improvement projects over the years, with the most recent significant work being a $14,000 reroofing project initiated in November 2022. Historical records show the replacement of approximately 10 rear exterior stairs treads in 2001, installation of aluminum windows in 1990, and an earlier reroofing project in 1990.

The building has experienced a few notable safety and compliance issues, particularly in recent years. In October 2023, a violation was issued regarding sleeping area requirements, representing the most current safety concern. The property had a sprinkler/standpipe systems violation in December 2021 (which was subsequently abated), and a fire alarm system issue in 2010 that was corrected.

Multiple fire incidents have been recorded, though none involving civilian injuries or significant damage, primarily consisting of alarm activations, false alarms, and isolated cooking-related incidents. The building has undergone regular housing inspections in 1999, 2001, 2008, and 2016, with most issues being promptly addressed. Recent activity around the property has primarily involved parking-related enforcement actions, with multiple citations issued for blocked driveways between October 2024 and January 2025, along with reports of sidewalk defects and garbage issues in late 2024.
