Single-family houses on generous lots define Amherst: Census estimates count about 3,930 detached homes out of roughly 4,580 housing units, and owners live in about nine of every ten occupied homes. Most were built between the 1960s and the 1980s, a cluster of older homes surrounds the town green, and the town’s hazard plan tracks how past droughts have hit local wells. A homeowners policy here has to fit all of that.
We are Portsmouth Atlantic Insurance, an independent agency owned by one family since 2005, with our office at 601 Islington St, Unit 206, Portsmouth, NH. Amherst homeowners work with our team by phone and email. We compare 40+ carriers for a 1970s colonial off Route 122, an antique Cape near the green or a newer house on a cul-de-sac. You can write to insure@portsmouthatlanticins.com or phone (603) 431-4020.
Key takeaways
- About six in ten owner-occupied Amherst homes were built between 1960 and 1989, so roof, wiring and heating updates drive much of the quote.

- The town’s hazard plan names Mac Hill and Chestnut Hill as the areas most prone to wildfire.
- About 15% of Amherst lies in mapped floodplain; flood needs its own policy.
- We can write Amherst homes with carriers that include Vermont Mutual, Hanover, Andover, Cincinnati, Chubb and Plymouth Rock, among others.

Amherst homes by the numbers
The figures below come from five-year Census survey data covering 2020–2024 for the town of Amherst. Treat them as estimates; each carries a margin of error.
| Measure (ACS 2020–2024) | Amherst | Source |
|---|---|---|
| Median value of homes lived in by their owners | $537,600 | B25077 |
| Median income of all homes in town | $153,196 | B19013 |
| Share of occupied homes lived in by owners | About 4,200 of 4,570 occupied homes (about nine in ten) | B25003 |
| Detached single-family houses | About 3,930 of 4,580 housing units | B25024 |
| Built in the 1970s (homes lived in by owners) | About 1,170, the largest single decade | B25036 |
| Built 1960–1989 (homes lived in by owners) | About 2,590 (roughly six in ten) | B25036 |
| Built in 1939 or earlier (homes lived in by owners) | About 460 | B25036 |
| Valued at $750,000 or more (homes lived in by owners) | About 540, including roughly 210 at $1 million or more | B25075 |
For insurance, the median value is less important than what it would cost to rebuild. A 1970s colonial with a finished basement, a two-car garage and a detached barn can cost more to replace than what it would sell for, especially with current labor and material costs. We set the dwelling limit from a replacement cost estimate, not the assessment.
Houses from the 1960s through the 1980s
Most Amherst homes are now 35 to 65 years old. Underwriters look at whether the original systems have been replaced, and a few items come up again and again on houses from this era:
- Roof age and material. An asphalt roof past its expected life can limit carrier choices or lead to roof payments on an actual cash value basis. A documented replacement date helps.
- Electrical panel and wiring. Some carriers ask specifically about older panels and about any original wiring that has not been updated.
- Heating. Oil tanks (age and location, especially in the basement), wood and pellet stoves, and the date the furnace or boiler was installed.
- Plumbing and water. Supply lines to the washer, dishwasher and fridge, water heater age, and whether you have water leak detection or automatic shutoff, which some carriers credit.
- Finished basements. Water backup of sewers or drains, including a failed sump pump, is excluded unless you add it by endorsement.
If your home is older still, our older and historic home insurance page for New Hampshire covers what carriers ask about knob-and-tube wiring, stone foundations and plaster walls.
The Amherst Village Historic District
Voters created the Amherst Village Historic District at the March 1970 Town Meeting, and late in 1982 the National Register of Historic Places accepted 167 buildings and properties within it. In 1986 the town expanded the local district to cover the approaches to the village, bringing in 147 more properties, according to the Historic District Regulations and Design Guidelines adopted in January 2026.
Those guidelines shape what happens after a loss. Deteriorated features are to be repaired rather than replaced whenever possible, and where replacement is needed, the new material is to match the old in composition, design and texture. Aluminum or vinyl siding is not permitted, nor are vinyl or solid fiberglass replacement windows, and roofs that define a building’s character are protected. Most exterior changes need a Certificate of Approval from the Historic District Commission before work begins, though ordinary maintenance with the same materials, storm windows that keep original features, and repainting do not.
For your policy, that points to three things: a dwelling limit that reflects wood clapboards, true divided-light windows and period trim; extended replacement cost, which adds a cushion above the dwelling limit, where a carrier offers it; and enough ordinance or law coverage to pay for upgrades the town or building code requires during a rebuild.
Wells, lightning and wildfire
Amherst’s hazard mitigation plan (2015 update, prepared with the Nashua Regional Planning Commission) records events that bear directly on homeowners:
- Drought. Wells went dry for two years running in the mid-1960s, and the 1999 and 2002 droughts brought low water in dug wells; 2002 marked the first Level 3 drought emergency. A homeowners policy does not pay to deepen a well that runs dry.
- Lightning. The plan lists a home struck by lightning on Nathanial Drive in 2011, along with strikes on large trees in the Amherst Village Oval in 2001 and 2006. Lightning damage to the house, its wiring and electronics is a covered peril; surge protection still helps.
- Wildfire. The plan identifies larger wooded areas such as Mac Hill and Chestnut Hill as particularly prone to wildfire. Clearing brush and keeping firewood away from the house help, and so does clear access for fire trucks on a long driveway.
- Snow load. The plan recalls March 9, 1931, when the porch roof of the Moonbeam Ballroom at Baboosic Lake collapsed under rain-soaked snow and pulled down much of the building. Collapse from the weight of ice and snow is generally covered; ice dam leaks depend on how the water gets in.
Flooding along the Souhegan
The same plan puts about 15% of the town inside mapped floodplain, most of it in the zone with a 1-in-100 yearly chance of flooding and the rest in the 1-in-500 zone. Among the roads it flags as prone to flooding are Stearns Road, Route 122, and the stretch of Boston Post Road where it crosses the Souhegan. A homeowners policy excludes flood from rising water, so a house near the river or one of its brooks needs a separate flood policy. We place new NFIP policies through Selective and can compare private flood options such as Neptune Flood. Check your address on FEMA’s Flood Map Service Center and see our flood insurance page.

Frequently asked questions
What does a homeowners policy in Amherst cover?
A standard policy covers the house, detached structures such as a barn or garage, your belongings, the extra cost of living elsewhere after a covered loss, and your personal liability. It responds to fire, lightning, wind, hail, the weight of ice and snow, theft and sudden water damage. Flood from rising water and earth movement are left out and need separate coverage.
My house is in the Amherst Village Historic District. Does that change my insurance?
It changes what a rebuild involves. The district’s design guidelines favor repairing original features, call for replacements that match the original material, and do not permit vinyl or other synthetic siding or vinyl windows. Your dwelling limit should reflect that kind of work, and ordinance or law coverage helps with costs that come from complying with codes and rules during repairs. Exterior work in the district generally needs a Certificate of Approval from the Historic District Commission first.
What affects the cost of homeowners insurance in Amherst?
The biggest factors are the rebuilding cost of the house, the age and condition of the roof, wiring, plumbing and heating, your claims history, your deductible and the coverage options you choose. Distance to a fire station and hydrant, a wood stove, a pool or a trampoline, and a home business can matter too. Pairing your car insurance with the home often helps, and we compare carriers side by side so you can see how each one treats your house.
Does homeowners insurance cover my well pump or septic system?
A sudden covered event, such as lightning frying the well pump, is often covered under the dwelling. Wear and tear, a well running dry in a drought, or a septic system failing with age generally is not. Some carriers offer equipment breakdown and service line endorsements that reach further, and those are worth asking about on a house with a private well and septic.
How much personal liability should an Amherst homeowner carry?
Most policies start at a modest liability limit, and many owners raise it to the highest the home policy allows. If you have significant assets, teenage drivers, a pool, or a dock at Baboosic Lake, an umbrella policy adds a much larger layer over your home and car policies.
Can I insure a vacation or second home through you?
Yes. Amherst itself has very few seasonal homes, but many Amherst owners also have a lake house or a ski place elsewhere. A second home can often go with the same carrier as your primary home, and our seasonal home page explains what changes when a house sits empty part of the year.
What do you need for an Amherst homeowners quote?
The address, year built, square footage, roof age and type, heating system and fuel, updates to wiring and plumbing, any pool or wood stove, the names of everyone in the home and the declarations page from your current policy. Request a quote. There’s no obligation to buy. The form on this page works, or reach us at insure@portsmouthatlanticins.com or (603) 431-4020.
