For years, financing was the thing most likely to derail a Peninsula home purchase in escrow. In 2026, insurance has quietly become just as real a risk, and it is catching buyers and sellers off guard because it is a genuinely new problem that older habits and assumptions have not caught up with yet.
How Bad Has It Actually Gotten
Stanford research published in mid-2026 found that average California homeowner insurance premiums rose 84% between the end of 2020 and March 2026, while average deductibles climbed from roughly $1,813 to $2,553 over the same period. Seven of California’s twelve largest home insurers have reduced or stopped writing new policies in the state entirely, shifting more of the burden onto the FAIR Plan, the state’s insurer of last resort. The FAIR Plan now covers about 5% of California single-family homes, up from just 1.5% at the end of 2020, and backs roughly 6% of new mortgage originations statewide.
This Is Not Just a Fire-Country Problem Anymore
One of the more surprising findings in the Stanford research is that FAIR Plan dependence is now showing up in moderate and even low wildfire-risk zip codes at roughly twice the rate of its overall market share. Nearby affluent Bay Area communities have seen their FAIR Plan exposure spike sharply in just the past year or two. For Peninsula buyers, this means hillside neighborhoods in Belmont, San Carlos, and Redwood City’s Emerald Hills deserve real insurance due diligence, not an assumption that “it won’t happen here.”
Why This Can Actually Kill a Deal
If a buyer cannot produce an insurance commitment before closing, the lender will not fund the loan, regardless of how clean everything else about the transaction is. Real estate agents across California are reporting rising rates of deals falling apart in escrow specifically over insurance, not financing or inspection issues, a shift from just a couple of years ago.
What Buyers Should Do Differently in 2026
| Start requesting insurance quotes the day you go into contract, not the week before closing |
| Ask specifically whether the property has any history of FAIR Plan coverage or non-renewal by a previous insurer |
| For hillside or wooded lots, budget for the possibility of FAIR Plan coverage plus a separate policy for non-fire risks, which together often cost more than a single standard policy |
| Do not remove your inspection contingency until you have a real insurance quote in hand, not just a preliminary estimate |
What Sellers Should Know
Sellers in higher-risk pockets are increasingly seeing longer days on market and offers that explicitly account for $8,000 to $15,000 or more in annual insurance costs. If your home sits in a hillside or wooded location, getting a sense of your own current insurance situation, and any recent non-renewal history, before you list can help you set realistic expectations and avoid a surprise mid-escrow.
Key Takeaway
Insurance has become a genuine transaction risk in California, not a formality. On the Peninsula, hillside properties deserve the same early attention buyers used to reserve for financing and inspections.
Frequently Asked Questions
What is the California FAIR Plan?
It is the state’s insurer of last resort, covering fire, smoke, lightning, and explosion, with other coverage needing to be purchased separately.
Can insurance problems really stop a closing?
Yes. Without an insurance commitment, lenders will not fund the loan, which can end an otherwise clean transaction.
Are flat, downtown Peninsula neighborhoods affected too?
Less than hillside areas, but statewide data shows FAIR Plan reliance rising even in moderate and low-risk zip codes.
When should I start shopping for insurance during a purchase?
The day you go into contract, well before you consider removing your inspection contingency.
