1226 Masonic Ave, San Francisco, CA 94117

The property at 1226 Masonic Ave is a two-unit, two-story multi-family residential building located in the Buena Vista Park neighborhood. Built in 1900, this flats/duplex structure has undergone several significant modifications throughout its history.

The most notable historical event was a substantial fire in 1991 that required $100,000 in repairs. Since then, the building has seen various improvements, including the conversion of basement space into a rec/exercise room and non-commercial office space in 2003, during which electrical work was completed for lighting, switches, and receptacles in multiple areas. Most recently, in late 2024, there has been an active complaint regarding toxic fumes from wood preservative ("super green brown") used during siding replacement, which has been reported to the Building Inspection Division and remains unresolved.

The property has also experienced multiple issues with driveway blocking, with at least seven enforcement actions taken between November and December 2024, resulting in citations in some cases and officers being unable to validate the complaints in others. Additionally, there is an open street defect complaint filed in November 2024 regarding curb or curb ramp issues. Two fire incidents were recorded in the building's recent history: a medical assist call and a malfunctioning alarm, neither of which resulted in civilian injuries.
