663-665 24th Ave, San Francisco, CA 94121

The property at 663-665 24th Avenue in San Francisco's Central Richmond neighborhood is a 2-unit, 2-story residential building constructed in 1916, currently owned by the Stanley & Nellie Chu 2020 Trust. The building has undergone several significant renovations and improvements over the past two decades, with the most substantial work occurring in 2010 when major plumbing and electrical upgrades were completed, including the installation of new gas furnaces, comprehensive bathroom and kitchen remodeling, and full-unit rewiring with numerous outlets and lights.

The building underwent horizontal rear addition in 2009 ($279,000), and facade improvements including front stucco replacement in 2005 ($5,000). In 2014, maintenance work was performed to address dry rot issues in the garage area and front stairs.

The building experienced a lead paint hazard situation in 2007 when damaged paint was discovered, particularly affecting interior surfaces, though this issue was abated by September 2007. Recent maintenance and incident history includes a significant sewer discharge issue in November 2024, ongoing tree root problems affecting the sidewalk (reported October 2024), and several parking-related incidents including driveway blocking (most recently in January 2025). The property has been relatively well-maintained in terms of major systems, with regular updates to plumbing, electrical, and structural elements, though the recent sewer discharge issue represents the most significant recent maintenance concern.
