4047 Mission St, San Francisco, CA 94112

The Wong Family Revocable Trust owns the two-unit, two-story multi-family residential building located at 4047 Mission Street in Bernal Heights, a structure that dates back to 1948. The building has experienced several significant plumbing issues in recent months, with four separate sewage back-up incidents recorded between December 2023 and July 2024, all involving the side sewer vent and requiring field work to resolve. These recurring sewer problems represent the most pressing current maintenance concern.

Other recent building-related incidents include two pavement defect reports from January and September 2024 (one still open) and some graffiti issues in January 2023 that has since been resolved. The building's maintenance history shows regular upkeep, though some permits are now outdated or no longer valid. Notable past maintenance includes an electrical service upgrade to 200-amp meters in 2003, a wall repair in 2010 following damage from a vehicle (costing $3,000), and a reroofing project initiated in 2000 (permit expired).

A fire safety inspection in August 2012 noted combustible materials, though this condition was corrected the same day. While the building has experienced various neighborhood issues such as abandoned vehicles (two reports in 2023, both resolved), street pavement problems, and water service requests, these external matters are more related to the surrounding area than the building itself. The most pressing concern from the available data is the building's recurring sewer system challenges, which have required multiple emergency responses from the Public Utilities Commission Sewer Operations team.
