1446-1452 Mason St, San Francisco, CA 94133

The 6-unit, 3-story multi-family residential building at 1446-1452 Mason Street in Nob Hill, owned by Hung Tim Tse & Zheng Lilly, was constructed in 1913 and has had several notable events throughout its history. The building underwent routine housing inspections in 1999, 2001, 2004, 2007, and 2011, with violations recorded in 2001 and 2004 primarily related to fire safety issues, including problems with the fire escape system, gas utility shutoff requirements, and ventilation in the garbage room. A significant complaint was filed in 2006 regarding unauthorized demolition work at the back of the building, though this was resolved by 2012.

In 2011, work was completed to resecure loose exterior trim in preparation for painting, costing $1,000. The building has undergone consistent street space permit usage from 2017 through 2018, with multiple permits issued at minimal costs. More recently, from late 2024 through early 2025, there have been several calls to 311 regarding street-related issues near the building, including reports of illegal parking and debris on the street, with most cases being resolved through responses from city services.

Fire safety systems received attention between 2006 and 2008, with a fire alarm systems complaint that was ultimately corrected. There have been three documented fire-related incidents near the building since 2006, though none involved civilian injuries or were related to building fires, and included instances of alarm system activation, a carbon monoxide detector check, and a service call. The building appears to have maintained compliance with housing and safety requirements following the resolutions of past violations and complaints.
