470-472 22nd Ave, San Francisco, CA 94121

The property at 470-472 22nd Avenue is a two-unit, two-story multi-family residential building constructed in 1927, currently owned by Randall & Frances Wong since 1990. The building experienced significant maintenance issues in 2019, with two major complaints filed through Housing Inspection Services: one related to heating system problems, damaged ceilings, and various maintenance concerns (complaint #201992661), and another concerning serious safety and maintenance violations including mold, lack of fire escape access, and overgrown vegetation (complaint #201988611).

These complaints led to multiple violations requiring correction, including repairs to wood stairs, drainage pipes, windows, and the heating system, as well as addressing lead paint hazards. While most of these violations were officially abated by September 2022, several permits were subsequently issued and completed to address these issues, including repairs to rear stairs and handrails (2019), reroofing (2019), kitchen pipe repairs (2020), and a significant electrical service upgrade (2018) including 200-amp feeders and 60-amp service for each unit.

A stairway repair was also completed in 1992, indicating ongoing attention to this particular maintenance issue. The property has experienced several infrastructure and safety issues in recent years, including a 2023 report of collapsed sidewalk (currently open as of December 2023) and two parking violations for sidewalk parking in 2019 and 2020, both of which were resolved through police intervention. The building's maintenance history shows periodic attention to both structural and systems improvements, though the cluster of violations and complaints in 2019 suggests there was a period of significant disrepair that required substantial remedial work across multiple systems and safety concerns.
