Updated September 4, 2026. Quick answer: In Maryland your insurer must give you at least 45 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 code states no consequence at all. Ending the policy mid-term is a separate event on a separate clock: 45 days. Every answer below is taken from Maryland’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 Maryland law settles, in four lines
| Question | What the code says | Section |
|---|---|---|
| Notice required before non-renewal | 45 days | Md. Code Ins. § 27-602(c) |
| Must the insurer state a reason | The reason has to be in the notice | Md. Code Ins. § 27-604(b), |
| If the notice is late or defective | The code states no consequence at all | Md. Code Ins. §§ 27-601 to 27-608 |
| Notice required for mid-term cancellation | 45 days | Md. Code Ins. § 27-602(c)(1), (d), (c) |
Which policies this covers. Maryland’s rules cover ordinary personal insurance like an owner-occupied homeowners policy, and separately reach a narrower type of policy: homeowner’s insurance under which a onetime guaranteed fully refundable deposit is required, while excluding auto-liability, state-fund, and surety policies. Md. Code Ins. § 27-601
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 Maryland 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 Maryland requires
45 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.
(c) (1) Subject to paragraph (5) of this subsection, at least 45 days before the date of the proposed cancellation or expiration of the policy, the insurer shall send to the named insured at the named insured’s last known address, by a first-class mail tracking method, a written notice of intention to cancel for a reason other than nonpayment of premium or notice of intention not to renew a policy issued in the State.

Whether they have to tell you why
In Maryland, 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.
(b) (1) Whenever an insurer cancels or refuses to renew a policy subject to this section, the insurer must provide to the named insured a statement of the actual reason for the cancellation or refusal to renew. … (d) (1) The reason given in the statement of actual reason shall be clear and specific. (2) The use of generalized terms such as “personal habits”, “physical handicap or disability”, “living conditions”, “poor morals”, or “violation or accident record” does not meet the requirement of this subsection.

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 Maryland, the code states no consequence at all.
No quotable provision: this is a recorded absence, and the sections read contain none. Sections read: Md. Code Ins. §§ 27-601 to 27-608
The other letter: mid-term cancellation
45 days, and this is the clock that applies when the insurer ends the policy before its expiration date rather than declining the next term.
(d) At least 10 days before the date an insurer proposes to cancel a policy for nonpayment of premium, the insurer shall send to the named insured, at the named insured’s last known address, by a first-class mail tracking method, a written notice of intention to cancel for nonpayment of premium. … (5) An insurer may not cancel a policy midterm except: (i) when there exists: 1. a material misrepresentation or fraud in connection with the application, policy, or presentation of a claim; 2. a matter or issue related to the risk that constitutes a threat to public safety; or 3. a change in the condition of the risk that results in an increase in the hazard insured against; (ii) for nonpayment of premium; or (iii) in the case of homeowner’s insurance, conviction of arson.
What is specific to Maryland
- Maryland’s mid-term cancellation grounds list ends with a ground that applies to homeowner’s policies specifically and to nothing else on the list: in the case of homeowner’s insurance, conviction of arson. Md. Code Ins. § 27-602(c)(1), (d), (c)
- Maryland doesn’t just require a specific reason, it names the vague reasons an insurer isn’t allowed to use, expressly disqualifying phrases like “personal habits”, “physical handicap or disability”, “living conditions”, or “poor morals” as too generalized to satisfy the law. Md. Code Ins. § 27-604(b),
- Maryland requires 45 days’ notice and a specific written reason for a cancellation or non-renewal, but the statute never says what happens if the insurer skips either one; the search across every relevant section turned up no ‘not effective’, ‘void’, ‘continues in force’ or extension-of-term language was found at all. Md. Code Ins. §§ 27-601 to 27-608
- A brand-new Maryland homeowners policy gets none of these protections for its first six and a half weeks: the law expressly excludes policies in effect for 45 days or less, during which the insurer can cancel simply because the risk doesn’t meet its own underwriting standards. Md. Code Ins. § 27-601
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.
