The law gives you 75 days. Here is how to use them.

California Insurance Code section 678 sets the timing. If your insurer will not renew, it must mail or deliver a notice at least 75 days (90 days beginning January 1, 2028) before your policy expires. The 90 days come from a 2026 law, SB 1301.

This applies no matter the reason: your house, your claims history, or the company pulling back from your area entirely. After a declared wildfire emergency, a moratorium can bar non-renewals for wildfire risk in and around the fire area. If the insurer renews with less coverage, the offer must list "any reduction of limits or elimination of coverage" at least 45 days before the policy ends.

The notice also has to say something. It must give the reason for the non-renewal. It must also come with a note about the Department of Insurance's Home Insurance Finder, a free lookup of insurance companies and agents by ZIP code.

If the reason on your letter is one vague sentence, ask the company or your agent for the specific reasons in writing.

None of this stops the non-renewal. The rule is not a right to keep the policy. It is a right to time, and a right to be told why.

The notice period runs from the day the notice was mailed or delivered. Not the day you opened it, and not the date printed at the top of the page. Those three dates are often different from each other, which is why the envelope is worth keeping.

If the insurer mails the notice, it must also add days for the mail, which the Department of Insurance calls "extra mail time-delay-days." Code of Civil Procedure section 1013 extends "any period of notice" five calendar days when the place of mailing and the place of address are both in California. It extends it 10 calendar days when either is outside California but within the United States, and 20 when either is outside the United States.

If the notice went out late, the law has a fix. Your policy stays active, on the same terms and price, for 75 days (90 days beginning January 1, 2028) from the day the notice was given.

You do not lose coverage on the printed expiration date. You get the full window the law intended.

Insurers get this wrong, and it is worth checking every time. Compare the postmark date against the expiration date in your policy paperwork, and count the days. If the gap is short, you have more room than the letter suggests.

75 days is enough time to do this properly. It is not enough time to set the letter aside for ten weeks.

The homeowners who end up rushed into the most expensive option are almost always the ones who started with three weeks left.

Here is what the window looks like when you use it.

• Week one: write down three dates: when the notice was mailed, the date on the letter, and your expiration date.
• Week one: also confirm the 75-day math and read the stated reason for the non-renewal.
• Week one: gather your home's basics: roof age and material, year built, and square footage.
• Week one: also note when you last updated the plumbing, wiring, and heating, and any claims in the last five years.
• Weeks two and three: search standard and specialty insurers, in one pass.
• Compare the yearly price, the rebuild coverage amount, and the deductible together, not just the price by itself.
• Weeks four through eight: if you need a repair done or a document tracked down, this is your window. That room disappears once you wait too long.
• Before the expiration date: have your new policy active, with no gap between the two.
• If you have a mortgage, send the new policy to your mortgage company and confirm they have it.

A non-renewal ends coverage at the end of a policy term. A cancellation ends it in the middle of one.

They are not the same event, and the 75-day rule does not cover a cancellation at all.

Once a home policy has been active 60 days, or from day one of a renewal, Insurance Code section 676 limits cancellation to a short list of reasons. They are an unpaid bill, fraud or a false fact that mattered, physical changes making the home uninsurable, and a conviction or gross negligence raising a covered risk. In a new policy's first 60 days, the list does not apply.

The notice is much shorter: at least 20 days before the cancellation takes effect, or at least 10 for nonpayment or fraud (section 677.4). A mailed notice gets the same extra days for the mail. Section 677 requires it in writing, and after the first 60 days, or on a renewal, it must name its reason.

The practical difference is time. A non-renewal gives you at least 75 days (90 days beginning January 1, 2028). A cancellation can give you under three weeks.

If your letter says cancelled, not non-renewed, treat it as urgent. Read the reason first: a non-payment cancellation can sometimes be fixed just by paying. If the insurer acted because you host short-term renters, read what California law allows over hosting.

Start with the paperwork. Keep the envelope, photograph the postmark, and write down three dates: when it was mailed, the date on the letter, and your expiration date.

Then ask the insurer, in writing, to confirm when the notice was mailed. Get it in writing, because that date is the whole question.

If the math says the notice was late and the company will not continue your coverage, you can file a complaint with the California Department of Insurance. Their consumer services unit handles exactly this kind of timing question, and it costs you nothing.

Do that while you shop, not instead of shopping. Being right about the date can add weeks of coverage, and those weeks only help if you spend them looking.

Either way, the outcome you want is the same: a policy you chose, active before the old one ends.
