1827-1831 Mason St, San Francisco, CA 94133
The three-unit residential building at 1827-1831 Mason Street in Russian Hill, owned by the Lee Kai Mee Revocable Trust, is a three-story flats and duplex structure built in 1916. The property has undergone some significant maintenance work, including a reroofing project in 2013 that cost nearly $12,700, and had two street space permits issued in 2015.
A notable inspection in June 2016 resulted in multiple violations across various categories, including fire safety, security, and building maintenance, though these violations are now listed as not active. The 2016 violations included issues with handrails, fire extinguishers, carbon monoxide alarms, garage usage, emergency egress, and self-closing doors, all of which fell under the jurisdiction of different building codes and housing regulations. In terms of recent activity, the building has generated multiple sanitation-related service calls in late 2024, primarily regarding garbage and debris on the street, with several cases being closed with no work needed or marked as resolved.
There are also three recent tree-related service calls from September 2024, including one regarding a fallen tree that has since been resolved. The building's history shows regular routine inspections by Housing Inspection Services in 1999, 2003, 2006, and 2016, indicating ongoing oversight of building conditions. While the property's most recent violations from 2016 were addressed, it's worth noting that the building's exterior area has experienced recurring issues with street cleaning and debris management in recent months.
