Double Rock Grocery Fails with Sewage Overflow in Basement

A Bayview grocery store failed its health inspection after San Francisco health officials discovered a severe sewage overflow problem that had been festering in the basement for more than a month. Double Rock Grocery at 2830 Ingalls Street received a failing grade during this inspection on October 14, 2025, when Inspector Montre Tieu found extensive sewage overflow conditions that posed significant health risks to the community.

Inspection Details

The inspection, which combined both a complaint investigation and routine check, uncovered alarming sanitary conditions in the facility's basement. According to the inspector's report, severe sewage had been overflowing from a floor basin connected to the sewer system on and off for more than one month before the inspection took place. Inspector Tieu documented that the sewage overflow was connected to the main sewer line through a floor basin, creating a persistent contamination issue that had gone unaddressed for an extended period. The ongoing nature of this problem suggests serious infrastructure failures that could have posed health risks to anyone entering the basement area. While the inspector noted that the basement area did not store food products, the presence of raw sewage in any part of a food establishment creates serious concerns about cross-contamination, pest attraction, and overall sanitary conditions that could affect the entire facility.

Health Violations Found

The facility received one critical violation under Section 22 for "Sewage and Wastewater Properly Disposed." This critical violation indicates that the sewage disposal system was not functioning properly, creating conditions that could harbor harmful bacteria, parasites, and other disease-causing organisms. Raw sewage contains dangerous pathogens including E. coli, Salmonella, and hepatitis A virus, which can cause serious foodborne illnesses. Even though the contaminated basement area reportedly did not house food storage, the proximity to a food establishment raises concerns about potential contamination pathways through staff movement, pest activity, and airborne contaminants. The inspection report specifically noted that the sewage problem had been intermittent, occurring "on and off" for over a month, suggesting that management may have been aware of recurring issues but failed to implement permanent solutions to protect public health.

Facility Closure and Remediation

As a result of the serious sanitary violations, Double Rock Grocery has been closed for an extensive remodel that is expected to continue until late December 2025. This extended closure timeline suggests that the sewage problems require significant infrastructure repairs beyond simple plumbing fixes. The inspector's report indicates that multiple agencies and plumbing professionals need to be contacted to address the underlying problems. This coordinated response suggests the sewage issues may involve complex municipal sewer connections or structural problems requiring specialized expertise. Located near the T-Third Muni line, the grocery store serves the Bayview community, which will need to seek alternative shopping options during the extended closure period.

Previous Inspection History

This appears to be the first recorded health inspection for Double Rock Grocery in the current database system, making it impossible to determine if similar problems existed previously or if this represents a new development at the facility. The facility is owned by Joyce L. Knighten and can be reached at (415) 822-5350 for questions about the closure and anticipated reopening timeline. Customers who visited the store before the closure and experience symptoms such as nausea, vomiting, diarrhea, or fever should consult with healthcare providers, as these could indicate exposure to sewage-related pathogens.
