2411 23rd Ave is a two-story, 8-unit multi-family residential building constructed in 1958, currently owned by S&P Ng Family Trust 2007. The property has undergone several significant safety upgrades in recent years, including a completed soft-story retrofit in 2017 (estimated cost $65,000) as part of the city's seismic safety requirements and the installation of low-frequency fire alarm sounders in sleeping areas to enhance fire safety in 2017. The building's maintenance history shows attention to basic infrastructure needs, with completed projects including a reroofing in 2009 ($8,600), window replacements in 2009, and a fire alarm system upgrade.

The building has experienced multiple maintenance and safety issues over the years, with some persistent concerns. Notable recent issues include a complaint in October 2024 regarding possible illegal group housing and heating problems. A significant incident occurred in 2011 involving a hole between the garage and bathroom causing air quality issues and the presence of abandoned vehicles.

The building underwent various safety corrections in 2001, addressing multiple violations including lead paint concerns, fire escape egress, and fire door requirements, though all these violations were abated by February 2001. More recent complaints (2023-2024) primarily relate to exterior maintenance and parking issues, with multiple reports of vehicles blocking driveways and sidewalk parking. Two fire-related incidents were recorded, both involving alarm systems in 2011 and 2017, with conditions corrected promptly. The property has maintained compliance with soft-story retrofit requirements and has received regular attention to fire safety systems, suggesting ongoing management attention to critical safety systems.
