The insurance market built for the homes insurers turn down.
Surplus lines insurance is coverage from specialty insurers built for the homes standard insurers turn down. In 2025 these insurers wrote more than 300,000 California home policies, up from about 50,000 in 2023. Here's how it actually works, no jargon.
The short version
- The surplus lines market is a large, regulated group of specialty insurers built for homes the standard insurers turn down.
- Specialty insurers are not licensed by California and do not file their prices with it, but licensed specialists must place their policies under state rules.
- Three protections apply to every surplus lines policy: standard insurers are checked first, you sign a short state notice, and taxes and fees are itemized.
- One real gap: surplus lines policies aren't backed by California's guaranty fund, which is why the insurer's financial strength rating matters more.
Why this market exists
This market exists because wildfire risk in California changes faster than standard insurers can update their filed prices. Standard insurers file their prices and rules with the state, which makes them slow to change. When risk moves faster than that, standard insurers respond by narrowing what they'll write.
That's the backup this market provides: regulated specialty insurers with more flexibility on pricing and terms, built to take on homes standard insurers step away from.
It is not new, and it is not exotic. Much of California's commercial property, high-value homes, and brush-exposed homes have been insured this way for decades.
In 2023, specialty insurers wrote about 50,000 new California home policies. In 2025 they wrote more than 300,000, according to the Surplus Line Association of California.
That growth is not just about wildfire. In fast-growing areas, even homes with no real fire risk end up here too, simply because there was not enough room left with standard insurers.
Non-admitted doesn't mean unregulated
Non-admitted means the insurer is not licensed by California, so it does not file its prices with the state the way standard insurers do. It does not mean unregulated: the people who place these policies are licensed, and the state sets rules for which insurers they may use.
The people who arrange this coverage are licensed specialists with real legal duties. The insurers themselves must meet California's standards for financial strength, and carry ratings you can check.
Ask us who the insurer is, and its financial strength rating, any time before anything is final. There's real paperwork behind a policy like this, and we handle all of it for you.
One honest difference: these policies are not covered by California's state guaranty fund, the safety net that backs up standard insurers if they fail. You'll see this disclosed to you in writing before you buy. It's the reason financial strength ratings matter more here, and the reason we show them to you.
The rules that protect you
Three things happen with every legitimate policy in this market.
- Standard insurers come first. If one will cover your home, that's the better answer, and you should have it before looking anywhere else.
- You'll sign a short state notice, the D-1, before the policy starts. It explains what non-admitted means for you, and signing it is normal.
- Taxes and fees are itemized. These policies carry a state tax and a stamping fee, shown as separate line items, never hidden in the price. If a quote doesn't itemize them, ask why.
How you get there
You can't shop this market yourself: specialty insurers don't sell directly to consumers. The path runs through a licensed professional with access to this market, which is why most homeowners have never had it checked for them at all.
That's exactly what Casa was built to do: one form, standard insurers first, then specialty insurers, in one pass. We handle all of it for you.
When this market is the right answer, and when it's not
It's the right answer once standard insurers have genuinely said no, and the alternative is thin coverage or none. It's the wrong answer if a standard insurer would still say yes, since their policies are backed by the state guaranty fund and their pricing is filed.
That's why checking standard insurers first matters. Skipping that step is not a shortcut. It is a red flag.
Questions people ask us
Is surplus lines insurance real insurance?
Yes. These are real policies from rated specialty insurers, arranged by licensed professionals under California's rules for this market.
Will my mortgage lender accept it?
Lenders accept these policies routinely. What they check is the coverage amount, how a claim would get paid, and their own name on the policy. A rated policy on a hard-to-place home is a normal thing for a California lender to see.
Why is my price higher than my old policy?
Because this market prices the risk your standard insurer would not take at all. The right comparison isn't against your old price. It's against the California FAIR Plan's fire policy, which covers less, or against having no coverage at all.
What is the D-1 form?
The D-1 form is a short state notice, signed before the policy starts, that says your insurer is non-admitted and explains what that means. Everyone who buys this kind of policy signs one.
