538-540 24th Ave, San Francisco, CA 94121

The three-story multi-family residential building at 538-540 24th Avenue in the Central Richmond neighborhood, owned by Donald M Wong Exemption Trust, has undergone several significant maintenance and upgrade projects since its construction in 1981. Most recently, in 2023, the building received a new roof costing $23,300, and underwent stucco repairs due to dry rot issues that were identified in March 2023, with the work completed in April 2023 as part of window replacement improvements.

In January 2023, all 12 exterior windows were replaced with new materials including Fiberx or fiberglass. The building's history shows earlier challenges with unauthorized unit conversions and maintenance issues, particularly during 2001-2002 when multiple housing violations were documented regarding water damage, mold, and unauthorized modifications.

These violations were resolved through various corrective actions, including a $62,000 unit legalization project in 2016 to properly configure the first-floor dwelling unit. More recent infrastructure concerns include two sewage backup incidents in August 2024, though these were promptly addressed by city services. The property has also experienced recurring issues with illegal parking and sidewalk blocking, as evidenced by multiple citations issued between 2020 and 2024, though these are external to the building's condition and maintenance.
