Cross into northern New England and the entire grammar of sidewalk law changes. In the 40 states we had read before these three, the recurring machine is city-orders-owner-pays. Maine, New Hampshire, and Vermont run the Massachusetts pattern instead: the town owes the duty, and the fights are about notice and liability, not about your wallet. New Hampshire even wrote the owner's exemption down in so many words.
New Hampshire: "without further assessment to the abutting owner"
RSA 231:113, in full: "The highway agent, under the direction of the mayor and aldermen of a city or the selectmen of a town shall have charge of the repair of all sidewalks therein constructed under the provisions of this subdivision, and such sidewalks shall be maintained, repaired and reconstructed by the city or town in which they are located without further assessment to the abutting owner."
That is the most explicit city-pays repair statute in our 50-state database. The one cost owners can face is at birth, not during life: when a sidewalk is first built by petition, RSA 231:112 lets the city "assess upon the owners of the property abutting on such street a portion not exceeding 1/2" of construction cost, payable over as long as ten years. After that, repair and reconstruction are the city's, forever, by statute. The liability side is town-flavored too: written notice of an "insufficiency" to the town is the trigger (RSA 231:90-93), and RSA 231:92-a immunizes municipalities for hazards "caused solely by snow, ice, or other inclement weather" under a good-faith winter maintenance policy.
Maine: the town's ways, and a notice-gated claim
23 M.R.S. 3651 sets the duty: "Highways, town ways and streets legally established must be opened and kept in repair so as to be safe and convenient for travelers." Sidewalks ride inside "ways"; no Maine statute orders abutting owners to repair them. Injured travelers "may recover for the same in a civil action pursuant to section 3655," but only after written notice of the specific defect and only if the town then "unreasonably neglects" to fix it in a reasonable time; there is no fixed day-count. One disclosure in keeping with our methodology: the text of section 3655 itself, which likely carries the claim's mechanics and any damages cap, resisted every retrieval attempt against the legislature's site and mirrors, so we quote what we verified and assert nothing about a cap.
Vermont: a permissive power and a narrower door than it first appears
Vermont's grant is purely permissive: "The legislative body of a municipality may construct and maintain suitable footpaths, bicycle paths, or sidewalks, or any combination of these, within the limits of town highways" (19 V.S.A. 905). May, not shall; and no owner duty anywhere.
The liability door is narrower than the other two states'. Vermont's statutory notice-and-recovery scheme (19 V.S.A. 985-987, with its 20-day written notice "within 20 days of the time of the occurrence of the injury or damage") is textually tied to "the bridge or culvert," not to ways generally. Our own verification caught this: the section our researcher first read as a general highway-claim clock names bridges and culverts specifically. So a Vermont sidewalk injury claim does not ride that statute, and anyone telling you that you have 20 days to file over a sidewalk fall in Vermont is quoting the wrong section. Claims against towns over sidewalks run into ordinary municipal-liability doctrine instead, a genuinely harder path.
What to do
- New Hampshire: keep 231:113 handy. If a city bills you for sidewalk repair on an established sidewalk, the statute's own words are your answer. Only initial-construction assessments, capped at half, are authorized.
- Maine: the written notice is the lever. The town's duty sharpens the moment a defect is reported in writing. Report, keep proof, and the "unreasonable neglect" clock starts running against them.
- Vermont: do not rely on the 20-day statute for sidewalks. It is a bridge-and-culvert provision. For a sidewalk injury, get advice on municipal-liability doctrine early, because no statutory claim path is waiting for you.
