Updated August 17, 2026. Quick answer: In Washington your insurer must give you at least 60 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, the insurer’s duty to renew is not displaced — the code makes renewal the default and a compliant notice the exception to it. Ending the policy mid-term is a separate event on a separate clock: 60 days. Every answer below is quoted from Washington’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 Washington law settles, in four lines
| Question | What the code says | Section |
|---|---|---|
| Notice required before non-renewal | 60 days | RCW 48.18.2901(1)(a) |
| Must the insurer state a reason | The reason has to be in the notice | RCW 48.18.2901(1)(a)(i) |
| If the notice is late or defective | The insurer’s duty to renew is not displaced — the code makes renewal the default and a compliant notice the exception to it | RCW 48.18.2901 |
| Notice required for mid-term cancellation | 60 days | RCW 48.18.290(1)(a)- |
Which policies this covers. Washington’s statute is the general one for all insurance policies, with medical malpractice, surplus lines and the narrow anti-arson fire route carved out. Homeowners policies are named inside its own text. RCW 48.18.290(1)(a), (4),
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 Washington the two carry the same notice period, and the rest of the answer follows from that word rather than from the state.
How much warning Washington requires
60 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.
Each insurer must renew any insurance policy subject to RCW 48.18.290 unless one of the following situations exists: (a)(i) For all insurance policies subject to RCW 48.18.290 (1)(a): (A) The insurer must deliver or mail written notice of nonrenewal to the named insured at least 60 days before the expiration date of the policy; and (B) The notice must include the insurer’s actual reason for refusing to renew the policy.
Whether they have to tell you why
In Washington, 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.
The notice must include the insurer’s actual reason for refusing to renew the policy.
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 Washington, the insurer’s duty to renew is not displaced — the code makes renewal the default and a compliant notice the exception to it.
Each insurer must renew any insurance policy subject to RCW 48.18.290 unless one of the following situations exists: (a)(i) … (b) At least 20 days prior to its expiration date, the insurer has communicated … its willingness to renew in writing …; (c) The insured has procured equivalent coverage …; (d) The contract is evidenced by a written binder …; or (e) The contract clearly states that it is not renewable …
The other letter: mid-term cancellation
60 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) For all insurance policies other than medical malpractice insurance policies or fire insurance policies canceled under RCW 48.53.040: (i) The insurer must deliver or mail written notice of cancellation to the named insured at least 60 days before the effective date of the cancellation; and (ii) The cancellation notice must include the insurer’s actual reason for canceling the policy. … (c) If an insurer cancels a policy described under (a) or (b) of this subsection for nonpayment of premium, the insurer must deliver or mail the cancellation notice to the named insured at least 10 days before the effective date of the cancellation.
What is specific to Washington
- Washington is the outlier where nothing gets shorter. The mid-term cancellation notice is the same 60 days as the non-renewal notice, with no reduced clock for ordinary reasons and no initial window letting the insurer cancel a new policy freely. Non-payment is the one exception, at 10 days. RCW 48.18.290(1)(a)-
- The section is captioned “Renewal required — Exceptions”, and that structure is the remedy: renewal is mandatory unless one of five listed situations exists, and the first of them requires a notice that is both at least 60 days early and states the insurer’s actual reason. A late or reasonless notice does not meet the exception. RCW 48.18.2901
- The insurance commissioner’s own rule sets the standard the reason has to meet — the true and actual reason, in clear and simple language — so a notice reciting “underwriting reasons” is not a stated reason. RCW 48.18.2901(1)(a)(i)
What this page does not tell you
- The remedy above is a reading of the section’s structure, not a phrase it uses. The code never says a defective notice is void. It makes renewal mandatory and then lists the exceptions, and a notice that fails the first exception does not displace the duty. Two other states are drafted identically and are read the same way here.
- 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.
