Updated August 17, 2026. Quick answer: In California your insurer must give you at least 75 days’ written notice before it declines to renew your homeowners policy, and the reason has to be in the notice. If that notice is late or defective, coverage is extended for a period the statute states. Ending the policy mid-term is a separate event on a separate clock: 20 days. Every answer below is quoted from California’s own code and the section is named and linked, because this is the kind of question where the section number is the answer.
What California law settles, in four lines
| Question | What the code says | Section |
|---|---|---|
| Notice required before non-renewal | 75 days | Cal. Ins. Code § 678(c) |
| Must the insurer state a reason | The reason has to be in the notice | Cal. Ins. Code § 678(a)(1)(B) |
| If the notice is late or defective | Coverage is extended for a period the statute states | Cal. Ins. Code § 678(c) |
| Notice required for mid-term cancellation | 20 days | Cal. Ins. Code § 677.4 |
Which policies this covers. The chapter quoted here covers residential property of not more than four dwelling units, the personal property in it and the related personal liability. Commercial risks run on a different set of sections with different numbers. Cal. Ins. Code § 675
Two different letters are in play and the codes handle them separately. A non-renewal declines to write the next term: the policy runs to its expiration date and stops. A cancellation ends the policy mid-term, before the date you have paid through, and is usually limited to grounds the statute lists. The first thing to establish about the letter in front of you is which one it is — in California the two carry different notice periods, and the rest of the answer follows from that word rather than from the state.
How much warning California requires
75 days. The number on its own is not the rule, though — a day count means nothing without the two things the statute states and the comparison tables drop: what it counts back from, and when the clock starts. Both are on the face of the section quoted here.
At least 75 days before the policy expiration, the insurer shall deliver the notice of nonrenewal to the named insured or mail the notice of nonrenewal to the named insured at the address shown in the policy.
Whether they have to tell you why
In California, the reason has to be in the notice. That matters more than it looks: the reason is the thing you would have to dispute, and a notice that gives none is a notice that does not comply.
A notice of nonrenewal of the policy. That notice shall contain all of the following: (i) The specific reason or reasons for the nonrenewal.
What a late or defective notice actually gets you
This is the part of the law worth knowing and the part that almost never appears in a comparison table. In California, coverage is extended for a period the statute states.
If an insurer fails to give the named insured a notice of nonrenewal at least 75 days before the policy expiration, as required by paragraph (1), the existing policy, with no change in its terms and conditions, shall remain in effect for 75 days from the date that the notice of nonrenewal is delivered or mailed to the named insured.
The other letter: mid-term cancellation
20 days, and this is the clock that applies when the insurer ends the policy before its expiration date rather than declining the next term.
A notice of cancellation with respect to a policy covered under Section 675 shall be delivered at least 20 calendar days prior to the effective date of the cancellation, except that in the case of a cancellation for nonpayment of premiums, or for fraud, the notice shall be given at least 10 calendar days prior to the effective date of the cancellation.
What is specific to California
- California’s 75-day rule is written to override the older 45-day figure still printed in the same section, and it applies to every policy expiring on or after 1 July 2020 — which is all of them now. A table quoting California at 45 days is quoting the surviving alternative path, where the insurer sends an offer of renewal instead of a non-renewal notice. Cal. Ins. Code § 678(c)
- The 20-day mid-term figure is the residential one. A separate section sets 30 days for commercial policies, and that is the number published tables usually report for California — it is the wrong subsection for a home. Cal. Ins. Code § 677.4
- The statute also forbids refusing to renew solely because a claim is pending, with a carve-out for earthquake coverage. Cal. Ins. Code § 675
What this page does not tell you
- This is what the code requires, not what a court has done with it. No case law was read. A state whose courts supply a remedy the code omits will read as silent here, and that is the honest limit of a statutory page.
- Your policy can be more generous than the statute and never less. These are floors. Your own contract may promise more notice; it cannot promise less.
- Catastrophe moratoria are a separate rule. Several states suspend non-renewals in a declared-disaster area on their own timetable, with their own trigger. Folding that into a notice period would misstate both.
- No federal answer exists to check this against. Congress left the business of insurance to the states, so the answer is genuinely different in every jurisdiction and a national number is not a thing that exists.
Two neighbouring questions are answered elsewhere: the claims file your insurer read before deciding and what your lender buys if you end up uninsured.
