Key takeaways
  • Moultonborough has 89 miles of shoreline, the most of any New Hampshire town, and 51 percent of its homes are seasonally vacant, per the 2025 hazard plan.
  • New docks and boathouses need an NHDES wetlands permit, town zoning bars expanding existing boathouses, and standard policies exclude ice damage to docks.
  • Boat-access islands, the single bridge to Black Cat Island and the one road onto the Neck all shape how carriers view fire response.
  • A nonconforming home destroyed by fire may be rebuilt in place, but the town gives owners 30 months to restore or replace it.
  • No fees, 40+ carriers, flood quoted alongside every home, boat coverage through five carriers, and claim help until resolution.

No town in New Hampshire touches more water than Moultonborough. Its 2025 Hazard Mitigation Plan, written with the Lakes Region Planning Commission, counts 89 linear miles of shoreline, the most of any town in the state, and the adopted Master Plan land use chapter says the same. Moultonborough Bay, the Neck, Long Island and a chain of Lake Winnipesaukee islands sit on the south side of town, with Squam Lake, Lake Kanasatka and several ponds to the north and west, all below the Ossipee Mountains and Red Hill. The Census Bureau put the year-round population at 5,293 in July 2025. In summer, the hazard plan says, as many as 25,000 more people arrive.

A shorefront estate on the Neck, a boat-access cottage in the bay and a hillside home with a view of the Ossipees are three very different things to insure. Jon Merwin founded Portsmouth Atlantic Insurance, a family-owned independent agency, in 2005. Today we hold licenses in 10 states, compare 40+ carriers for every home, and charge no fees on any line. We have earned 1,000+ Google reviews and over 2,000 testimonials from homeowners across New England, and we work with Moultonborough owners by phone, email and online.

Lakefront estates on Winnipesaukee

Most homes in town sit near water. The Master Plan land use chapter found that most residential development lines the shoreline and that much of it is seasonal housing, and the hazard plan lists strong waterfront development among the town’s defining land use patterns. Under the Moultonborough Zoning Ordinance, adopted in 1985 and most recently amended in March 2026, a waterfront lot needs at least 150 feet of shore frontage and 40,000 square feet of area, houses must stand at least 50 feet back from the high-water line, and no building may rise above 34 feet.

Big lakefront houses tend to be underinsured for one reason: the dwelling limit tracks what was paid for the house or an old estimate instead of what it would cost to rebuild. Custom timber framing, stone chimneys, walls of glass, radiant heat, a generator and a boathouse all push that number up, and shoreline sites add cost of their own, from barge deliveries to tight staging. We build each Moultonborough review around a current replacement cost estimate, then look at extended or guaranteed replacement cost, ordinance-or-law limits, and loss of use long enough to cover a full rebuild season.

Islands, the Neck and one-road neighborhoods

The hazard plan names more than a dozen Moultonborough Bay islands that are lived on in some capacity but reachable only by boat, among them Goodwin, Badger, Evergreen, Round, Whaleback, Black, Guay, Gansy, Birch Hill, Nineacre, Perch, Dow, Glines, Hermit and Hull, plus Kent Island on Squam Lake. Long Island and Black Cat Island can be reached by car, but Black Cat Island’s only access is a privately owned wooden bridge, and the plan calls for keeping in touch with the island association about bridge upkeep so emergency vehicles can still get across. The Master Plan notes that Moultonborough Neck Road is the only road into that part of town.

Underwriters ask the same questions about all of these places. How long would it take a fire crew to arrive, what would they draw water from, and what happens if the only road or bridge is blocked by a fallen tree? Fewer carriers write boat-access homes, so we present them carefully, with details on construction, heating, alarms, generators, fuel storage and who checks the property. A monitored smoke and low-temperature system and a clear plan for winter access go a long way.

Docks, boat lifts and boathouses

Building in the water involves two sets of rules. The state needs a wetlands permit for any new dock or boathouse, and for changes to the size, location or configuration of an existing one, according to the NHDES dock FAQ. Permanent piling or crib docks are allowed only on lakes over 1,000 acres where wind or waves make a seasonal dock impractical; boat lifts and jet ski lifts need a permit too. In November 2025, NHDES adopted rules that allow over-water boathouses for the first time in decades, limited to one story and 18 feet, and only as the least-impact option.

Town zoning adds its own limits. Section 4.6 says dug-in boathouses in or over the water are not allowed and that existing boathouses may not be expanded, and Section 3.2.2.5 keeps docks at least 20 feet from a side lot line. Stairs and walkways down to the water inside the setback need a special exception. Put together, an older boathouse may be very hard to replace in kind, so ask how your policy and the town would treat it after a total loss.

On the policy, a dock, lift or boathouse usually falls under other structures coverage, which is commonly 10 percent of the dwelling limit, and that is often too low on Winnipesaukee. Standard homeowners forms also exclude damage to docks and piers from freezing, thawing or the weight of ice, which is exactly what ice-out can do to a crib dock. Pull a seasonal dock before ice-in, keep its NHDES registration and photos on file, and list every structure on your application.

Boats, jet skis and liability on the lake

A homeowners policy offers little or nothing for most boats, and liability for a powerboat typically has to come from a separate watercraft policy. We write boat coverage through Progressive, Foremost Specialty, American Modern, Hanover and Chubb, matched to the boat’s size, horsepower and value; see our boat and watercraft insurance page. Guests on the swim raft, a tube behind the boat and a neighbor at the end of your dock are all liability exposures, so we line up the home, the boat and an umbrella policy so the limits fit together. If you keep collector cars or an SUV at the lake, ask about high-value auto coverage as well.

Second homes, empty winters and weekly rentals

The hazard plan cites the town’s 2025 Housing Needs Assessment: 5,821 housing units, 51 percent of them seasonally vacant, and a short-term rental market of 477 active listings, many of them on the water. The 2020 Census had counted 2,533 seasonal units out of 4,910. So a typical Moultonborough house may be open from June through October, closed for the winter, and rented for a few weeks in between.

Each of those choices matters to an insurer. Many policies narrow what they pay for frozen pipes, water leaks or vandalism after a house sits empty past a set number of days, and many restrict renting by the week unless the policy is written for it. Tell us how the house is heated in winter, who checks it and how often, and how many weeks it is rented. For more detail, see seasonal home insurance and our New Hampshire second-home guide.

Fire protection, dry hydrants and water supply

Moultonborough Fire Rescue works from the Public Safety Building on Whittier Highway and the Middle Neck Fire Station. The hazard plan describes ten full-time staff members and 12 to 18 call members across two fire rescue stations. In the 2025 Annual Town Report, the department logged 1,090 incidents, including 43 fires and 17 severe weather calls, and it described automatic aid with Center Harbor and Sandwich. It keeps a fire boat, and its crews train with a hovercraft on Winnipesaukee ice.

Water supply is the bigger underwriting question. About 980 homes are on community water systems and the rest of town relies on individual wells, according to the hazard plan, and the department maintains 107 dry hydrants plus 14 pressurized hydrants at Bald Peak Colony Club. In September 2025 the department joined a regional rural water supply drill, practicing long-distance water shuttles with other Lakes Region departments. When we quote a house, carriers want its distance to the nearest station and a reliable water source, so tell us about any nearby dry hydrant, sprinkler system or fire pond.

Wildfire is part of the picture too. The plan ranks it a high-risk hazard because most of town is heavily wooded, recalls the 1989 and 1990 Red Hill fires (262 and 316 acres), and singles out 231 single-family and 16 multi-family homes on Long Island’s northwest side where terrain, vegetation and poor access raise the risk, recommending the Firewise program there.

Wind, lightning and falling trees

Moultonborough sits between the Ossipee Mountains and Red Hill, and the hazard plan committee said that setting creates a wind tunnel, putting land along Routes 171, 109 and 25 and parts of the Neck at higher risk in high winds. A July 21, 2022 macroburst with winds over 70 knots downed more than 500 trees across Moultonborough, Tuftonboro and Effingham. Lightning has a local record as well: in 2005 a strike set a tree on fire that spread to and destroyed a cottage on Badger Island, lightning fires damaged two more homes that August, and a 2020 strike caused a structure fire.

Wind, falling trees and lightning are generally covered perils on a homeowners policy, subject to the deductible. What we check is whether the dwelling limit, other structures limit and debris removal coverage are large enough for a wooded shore lot, where one storm can mean a damaged roof, a crushed boathouse and a dozen trees to haul out by barge.

Heavy snow, ice storms and days without power

The town averages about 68 inches of snow a year, the hazard plan says, and it warns that several small storms can add up to the same roof load as one big one, with flat roofs most at risk. It notes that residents may have to go several days without power and that backup generators are common. The town report described a December 29, 2025 ice storm as the department’s busiest day of the year, with 29 incidents in one day. Moultonborough also has about 110 miles of private roads, most of them dirt, where plowing and tree clearing depend on the road association.

Homeowners policies generally cover roof collapse from the weight of snow and ice, though coverage for docks, decks and some detached structures can be narrower, and they cover sudden pipe bursts in a heated home. In a closed-up lake house, the risk is a furnace or power failure during a cold snap. A standby generator, sensors that alert you to low temperatures or leaks, and an automatic water shutoff all help. See our snow and ice damage guide for more.

Flood: lake levels, not rivers

The hazard plan says most flooding in Moultonborough comes from rising lake levels, not rivers and streams, and it judges the impact of flooding to be low. It flags flooding on private roads in the Balmoral subdivision and one recent flash flood, on June 28, 2023, that flooded and undermined part of Route 109. The town joined the NFIP on October 21, 2001. As of July 2024 there were 25 flood policies in force (8 in A zones, 17 in X zones), five paid losses and no repetitive losses. Since late 2022, OpenFEMA lists Carroll County in five major disaster declarations for storms or flooding, most recently one for June 2026 storms, all with public assistance for towns and none with individual assistance for homeowners.

Low risk is not no risk. A homeowners policy excludes flood, and a high lake against a walkout basement or a boathouse is flood, not water backup. We quote flood alongside every Moultonborough home policy, and our NFIP policies are written through Selective. For houses worth more than the NFIP building limit, we also look at private markets such as Neptune Flood, The Flood Insurance Agency and Aon Edge. Look up your address at the FEMA Flood Map Service Center, and see FloodSmart for NFIP waiting periods. For background, our New Hampshire flood coverage overview explains the choices.

Town floodplain rules also matter after a loss. Under the zoning ordinance, a building in a mapped flood zone that is substantially damaged, meaning repairs equal or exceed 50 percent of its pre-damage market value, must meet current floodplain construction standards. That is one more reason to carry ordinance-or-law coverage on an older shorefront house.

Rebuilding near the water: the 30-month window

Many lake cottages predate zoning and sit inside today’s 50-foot shore setback. Section 7.5.5.3 of the zoning ordinance allows a nonconforming structure destroyed by fire or another natural disaster to be restored or replaced within 30 months, as long as the rebuild creates no new or expanded nonconformity, and Section 7.5.5.4 requires it to meet current life safety and building codes. Work inside the 250-foot protected shoreland also needs state approval under the Shoreland Water Quality Protection Act, administered by NHDES, and the town will not issue a building permit until those state permits are in hand. Moultonborough applies some shoreland standards more strictly than the state, including a 30 percent cap on impervious surface within the protected shoreland.

Surveys, two layers of permits and builders booked well ahead can eat into 30 months quickly. That is why we look hard at additional living expense, ordinance-or-law and debris removal limits on older lakefront homes, so the policy pays for a complete rebuild in time.

Carriers for high-value lake homes

Replacement cost, not market value, decides which carriers fit. High-value policies tend to offer broader replacement terms, higher limits for jewelry, art and wine, and adjusters who know custom construction. Our page on high-value home insurance in New Hampshire has more detail. Each carrier decides on the specific house, so treat this as a rough guide:

  • Homes that cost less than about $2 million to rebuild: the large majority of our 40+ carriers are options.
  • Through about $5 million: National General and Openly can both be considered.
  • Cincinnati and Chubb both write homes at any dwelling limit, so we quote both. Cincinnati usually wants at least about $150,000 in dwelling coverage.

We have reviewed Openly, Cincinnati and Chubb in more depth.

When something goes wrong

Ice-out shoves a crib dock off its base, a squall drops a pine onto the porch roof, or you open the house in May to a burst pipe. Call us first. We help report the claim, explain what the adjuster needs to see, and stay in touch with you and the insurer until it is resolved.

Frequently asked questions

Do you insure homes in Moultonborough from Portsmouth?

Yes. Our license covers all of New Hampshire, and we serve Moultonborough homeowners by phone, email and online from 601 Islington St, Unit 206, Portsmouth. Call (603) 431-4020 to get started.

Can I insure a Moultonborough island home with no road access?

Yes, though fewer carriers write boat-access homes and they ask more questions. The town’s hazard plan lists more than a dozen inhabited Moultonborough Bay islands reachable only by boat. Expect questions about fire department access, heating, alarms, a generator and who looks after the property.

Does my homeowners policy cover my dock, boat lift and boathouse?

In most policies they fall under other structures, a limit that is often 10 percent of the dwelling limit and may be too low. Standard forms exclude dock damage from freezing, thawing or the weight of ice. New docks and boathouses need an NHDES wetlands permit, and Moultonborough zoning does not allow existing boathouses to be expanded.

Can I rent my Moultonborough lake house by the week?

Many owners do; the hazard plan cites 477 active short-term rental listings in town. But many homeowners policies restrict weekly rentals, so tell us how often you rent. We can find a policy written for rental use and add an umbrella for the extra liability.

If fire destroys my older lakefront cottage, can it be rebuilt in the same spot?

In many cases. Moultonborough zoning allows a nonconforming structure destroyed by fire or natural disaster to be restored or replaced within 30 months if the rebuild creates no new or expanded nonconformity, and it must meet current codes. State shoreland permits also apply within 250 feet of the lake.
