The 2-story, 4-unit apartment building at 414 23rd Avenue in San Francisco's Central Richmond neighborhood was built in 1923 and is currently owned by Louie Sisneros Survivors Tr. The property has undergone several significant structural improvements over its lifetime, including foundation bolting and plywood installation in 1990, back wall garage framing repairs, and stair repairs in the same year, followed by comprehensive compliance work in 1985. More recently, a sewer line repair was completed in 2017.

The building had a notable cluster of violations in October 2002 related to fire safety and gas utility shutoff requirements, though these issues were promptly addressed and abated by December 2002. Additionally, there was one routine housing inspection in 2011 that was resolved within weeks. The property has experienced recurring sidewalk parking issues over a 15-month period from late 2019 to 2021, with multiple citations issued and several instances where enforcement officers were unable to locate the offending vehicle.

A single fire-related incident is on record regarding a malfunctioning carbon monoxide detector, though no civilian injuries were reported. The most recent incident involving the property was a garbage and debris complaint in December 2024, which was resolved promptly. The building's historical and recent maintenance record suggests regular attention to structural integrity and compliance requirements, with most issues being addressed in a timely manner.
