533 Masonic Ave, San Francisco, CA 94117

The 4-unit, 2-story multi-family residential building at 533 Masonic Ave in the Lone Mountain neighborhood, owned by Hedda Kornfeld Family LP II, was constructed in 1923 and has undergone several significant maintenance and safety-related interventions over its history. The property experienced a major electrical system issue in December 2014 involving a Federal Pacific electric panel and faulty outlets, which led to multiple electrical permits and repairs throughout 2015, including light and switch replacements.

The building has a history of safety and maintenance concerns that required intervention, as evidenced by two routine housing inspections in 2001 and 2004, and a follow-up inspection in 2014-2016. The 2014 inspection identified several issues including electrical problems, lead paint concerns, weather-proofing deficiencies, and structural repairs needed for stairs and windows, all of which were addressed and abated by April 2016. Earlier repairs include a sewer line repair completed in 2014 and a reroofing project from 1994.

The building's maintenance history shows attention to pressing safety concerns, with all identified violations being formally abated. Recent infrastructure issues outside the building have been documented through 311 calls, including a collapsed sidewalk in 2023 and a pavement defect near the property in 2022, though these external issues don't directly pertain to the building's condition. The property has maintained an active record of addressing violations and completing necessary repairs, with no current active violations on record.
