1253-1257 Mason St, San Francisco, CA 94108

The three-unit, three-story multi-family residential building at 1253-1257 Mason Street in Nob Hill is a 1907 construction owned by Jew Ngon Sheng 1999 Revoc T. The property has experienced several notable maintenance and compliance issues over its history, with the most significant cluster of violations occurring in 2007, when multiple building and plumbing violations were documented and subsequently addressed by October of that year.

These included problems with drainage pipes, handrails, stairs, light well coverings, window sash cords, and plumbing issues, along with the need for building permits. During this period, there was also a staircase repair project completed at a cost of $1,000. Prior to this, in 2000, the building underwent routine inspections that revealed fire safety concerns including the need for a fire extinguisher and the posting of gas meter instructions, along with an egress obstruction issue—though these were also addressed by March 2000.

More recent history shows minimal issues, with only routine inspections being documented in 2011 and two public works service requests logged in late 2021 that were resolved. The building's violation history suggests a period of maintenance challenges in the mid-2000s, particularly regarding safety systems and infrastructure, though all identified issues appear to have been resolved according to available records. Since the 2007 violations were addressed, there have been no significant building code violations or major complaints on record for over a decade, indicating improved maintenance practices in recent years.
