What Actually Happened to Bay Area Homes This Week
Between November 13–15, 2025, a strong Category 3 atmospheric river dropped 1–5 inches of rain across the Bay Area in under 48 hours. While the news focused on street flooding and mudslides, thousands of single-family homeowners woke up to wet carpets, cracked foundations, ruined furnaces, and sewer backups — damage that standard homeowner insurance almost never covers.If you own a house in San Francisco, Oakland, Daly City, San Rafael, or the East Bay hills, this storm just became the most expensive rain event many of us have ever seen. The good news? Almost all of the damage was preventable with upgrades that cost far less than the repairs now hitting mailboxes.
