278-280 23rd Ave, San Francisco, CA 94121

The two-unit residential building at 278-280 23rd Avenue in the Central Richmond neighborhood, owned by Ieong Kon Neng Ao & Tan Cai, has undergone several significant maintenance events since its construction in 1922. The most recent major work was completed in June 2024, involving a $7,000 reroofing project, which is the second such roofing project recorded in 2024, indicating proactive maintenance of the building's envelope. The property has a documented history of addressing structural and pest issues, including termite repairs in 1986 and a garage leveling project in 1992.

Two reroofing projects were completed in 1991 and 2024, demonstrating regular upkeep of critical infrastructure. The building experienced three consecutive sewage backup incidents in August 2015, which were all resolved through PUC Sewer Operations intervention. While these incidents suggest past plumbing challenges, there have been no reported sewer issues since that time.

The property has also had multiple street cleaning and waste management incidents recorded through 311 calls, primarily relating to loose garbage and debris on or near the property, with the most recent being a garbage and debris complaint in August 2024. These calls for service were generally resolved promptly, though one general cleaning complaint in May 2014 resulted in no waste being found during inspection. A parking enforcement issue was recorded in October 2020, which resulted in the issuance of a citation.
