Short-Term Rental Management in the Dartmouth-Lake Sunapee Region, NH

What the Dartmouth-Lake Sunapee Region Is

The region spans three New Hampshire counties along Interstate 89 and the Connecticut River.

• The Upper Valley (Grafton County). Hanover is home to Dartmouth College, founded in 1769, and Lebanon to Dartmouth Hitchcock Medical Center, New Hampshire's only academic medical center and only Level I trauma center. Lebanon Municipal Airport has Cape Air service to Boston.
• The Lake Sunapee towns. New London (Merrimack County) has Colby-Sawyer College, Pleasant Lake and the New London Barn Playhouse. Newbury (Merrimack County) has Mount Sunapee Resort, the state park beach and The Fells. Sunapee, on the west shore, is in Sullivan County, as is Claremont to the west.

Demand and Seasons

The two halves of the region behave differently.

• Upper Valley demand is steady. Dartmouth's calendar drives the peaks: Commencement (June 14 in 2026), reunions and Homecoming (October 2 and 3 in 2026). DHMC brings patients' families, clinicians and traveling nurses all year, some for a month or more, which suits furnished mid-term rentals; see our mid-term rentals guide.
• The lake towns are seasonal. Summer is the peak, with lakefront weeks and the League of NH Craftsmen's Fair at Mount Sunapee in early August. Fall foliage keeps weekends busy, and winter follows Mount Sunapee's ski season.

The Rules Landscape

Every owner needs a New Hampshire Meals and Rooms license, and stays under 185 consecutive days carry the 8.5% rooms tax; see New Hampshire short-term rental laws and the NH rooms tax guide. Local rules, as of October 2026:

FAQ

Can I Run an Airbnb Near Dartmouth?

In Hanover, only in your principal residence and for up to 90 days a year. In Lebanon, the zoning does not list short-term rentals, so confirm with the city first. Furnished stays of a month or more are an alternative.

Does New England Host Co Manage Homes in Sunapee or Claremont?

Both are in Sullivan County, outside our listed New Hampshire counties. Call with the address and we will confirm whether a home is within 45 minutes of a crew base.

When Are the Busiest Weeks in the Region?

Dartmouth's Commencement, reunions and Homecoming in the Upper Valley, and July and August on Lake Sunapee, with early August's Craftsmen's Fair at Mount Sunapee.
