189-191 Corbett Ave, San Francisco, CA 94114

The two-story, four-unit multi-family residential building at 189-191 Corbett Avenue in Corona Heights, built in 1900, has undergone significant electrical improvements in 2023, with complete rewiring and new subpanels installed in all units between May 1-8, 2023, along with the installation of 150-amp underground service in 2004. The property has a history of various maintenance and compliance issues, with a notable cluster of violations in 2006-2011 related to fire safety and building codes, including problems with handrails, fire escape maintenance, egress obstructions, fire extinguisher requirements, and security features, though all these violations were ultimately abated by June 2012.

A 2011 complaint regarding unpermitted deck removal was also resolved. Recent building maintenance history shows attention to critical systems, particularly with the 2023 electrical upgrades. The property has experienced several infrastructure issues in the surrounding area, including a water main break in 2019, a fallen tree in 2018, and sidewalk defects in 2013.

The building underwent mandatory routine apartment inspections in 1998, 2006, and 2011, with all issues being resolved. Two significant tenant buyouts have occurred in recent years, with $100,000 paid to two tenants in 2022 and $137,500 to three tenants in 2024 at a nearby address (193 Corbett Avenue). The building's current owner, Sofia Mitina 2006 Revoc Tr, has maintained the property through periodic repairs and updates, with particular attention to electrical systems in recent years.
