What Massachusetts’s 45-Day Non-Renewal Law Actually Says
Massachusetts requires at least 45 days’ notice before a home insurance non-renewal takes effect — the shortest window of any state Coverage Clock covers. This page is just the statute — quoted directly and explained in plain language.
The statute, in its own words
“…the insurer will give written notice of its intent not to renew or reissue a policy to the insured at least forty-five days prior to the expiration of the policy…”
— M.G.L. c.175 §193P
Don’t confuse this with a cancellation notice: mid-term cancellation only requires 5 days’ notice to you (10 days if the stated reason is nonpayment) and 20 days to your mortgage lender, under a separate statute (M.G.L. c.175 §99). If your letter says “cancellation” rather than “non-renewal,” your timeline is much shorter than 45 days.
What this actually means for you
- Your insurer must give at least 45 days’ written notice of non-renewal.
- The notice must specify the reason for the decision — a bare notice with no explanation doesn’t satisfy the statute.
- This is the shortest statutory notice window among the states Coverage Clock tracks that set one — there’s less room to waste time than in CA, FL, or LA.
- Mid-term cancellation is a separate, much shorter process (5–10 days) — read your letter carefully to see which one you actually received.
