Coastal Home Insurance in Massachusetts

By Jon Merwin, Founder and CEO, Licensed Insurance Advisor

A house on the Massachusetts coast is rarely just a house. It is a Cape with cedar shingles a few streets back from a Falmouth beach, a year-round cottage behind a Marshfield seawall, a colonial in Newburyport that has watched the Merrimack rise and fall for a century, or a summer place on Martha’s Vineyard that the family has kept for three generations. Most of these are not mansions, yet near salt water each one runs into the same questions: who will insure it, what the wind deductible is, and what happens when the water comes in.

This page is for those everyday coastal homes. If your house is larger or more valuable, our coastal Massachusetts high-value home page and Massachusetts high-value home insurance page go deeper. We are licensed in Massachusetts and work with owners there by phone and email; our family-owned independent agency has been based in Portsmouth, NH since 2005. For each house we compare 40+ carriers. Write to insure@portsmouthatlanticins.com or phone (603) 431-4020 with questions.

With 1,000+ Google reviews and over 2,000 testimonials from clients, we are New Hampshire’s highest-rated agency on Google.

Wind and water: where the claim lands

After a nor’easter or a tropical storm, coastal damage nearly always sorts into two piles. Shingles torn loose, a window broken by flying debris, a tree on the porch roof and the rain that blows in through the gap are wind losses, which the homeowners policy generally pays once the wind deductible is met. Ocean water that tops a seawall, fills a basement or pushes through the first floor is flood, and homeowners policies exclude it. Without a flood policy, that second pile comes out of your own pocket.

That split matters more in Massachusetts than many owners expect, because the costliest local storms are often winter nor’easters rather than hurricanes. A slow storm that lingers across several high tides can do more harm to a low street in Hull or Scituate than a fast-moving hurricane that passes at low water.

What insurers look at on a coastal Massachusetts house

• Distance to the shoreline, often measured in bands, which can decide whether a wind deductible applies and which carriers will offer.
• Roof covering, age and attachment, since roof damage drives most wind claims.
• Windows and doors: shutters, impact-resistant glass and reinforced garage and entry doors.
• Foundation and elevation, especially in mapped flood zones; slab, crawlspace, full basement or pilings all read differently.
• Heating and plumbing, including how a seasonal home is kept warm and watched in winter.
• Occupancy: year-round, summer only or rented by the week.
• Claims history on the house and for you.

Wind and hurricane deductibles on the Cape, Islands and South Coast

The Massachusetts Division of Insurance explains that carriers may attach a specific wind or hurricane deductible to a policy, set either as a fixed amount or as a share of the dwelling limit, based on that limit and how close the home is to the coast (Mass.gov: Understanding Home Insurance). In its 2023 report on the Massachusetts home insurance market, the Division says these mandatory deductibles typically apply in coastal territories of Bristol, Plymouth and Barnstable counties and on the Islands, or within a set distance of the shore. Among the 25 largest home insurers, the highest share-of-limit deductible it found was one-twentieth of the dwelling amount, and roughly three in five coastal-area policyholders carried one in 2023.

The Division’s hurricane season reminder adds a detail many owners miss: check whether your wind deductible applies per storm, per season or per calendar year. The Atlantic season opens June 1, and the Division notes that Massachusetts tends to see the most activity from August on, so the time to read your declarations page is early summer.

Mitigation can change the picture

The same 2023 report found that six of the companies it surveyed will reduce or remove a mandatory wind deductible when a house has features such as storm shutters, impact-resistant glass, reinforced doors or roof and foundation tie-downs, and 18 offer credits for them. Not every carrier does this, and proof is usually required, so keep invoices and photos of any work. When we quote a coastal home, we ask about these features up front.

The FAIR Plan (MPIUA) and finding coverage near the water

The Massachusetts Property Insurance Underwriting Association, known as the FAIR Plan, was created in 1968 to provide basic property insurance to eligible owners who cannot get it in the voluntary market. It offers homeowners and dwelling fire programs. On the Cape and Islands it is a mainstream choice: the Division’s 2023 report shows the FAIR Plan writing about a third of home policies on the Cape and Islands, against fewer than one in ten in every other county.

FAIR Plan coverage is more basic than many voluntary-market policies, and its options and limits are narrower, so we treat it as one tool rather than the default. Since 2018 the plan has run a clearinghouse that offers FAIR Plan policyholders voluntary-market options through the agent listed on the policy. If you are on the FAIR Plan today, that is one more reason to have an independent agency review the home each year.

If you get a nonrenewal notice

The Division’s report notes that insurers must give 45 days’ notice before nonrenewing a home policy. It also found that in coastal areas nonrenewed policies had far more claims than renewed ones, while most coastal policyholders who did file a claim were still renewed. A single claim does not automatically end a policy, but a notice deserves a prompt call so there is time to compare options before the end date.

Flood insurance on the Massachusetts coast

Flood coverage is where coastal owners are most often underinsured. The Division’s 2023 report counted 11,524 NFIP policies on the Cape and Islands, 8,068 in Plymouth County and 8,333 in Essex County, out of 54,997 statewide, and estimated that only about nine homes in a hundred on the Cape and Islands had flood coverage. Private residential flood policies in Massachusetts grew from 1,668 in 2018 to 4,558 in 2023. State law also limits a lender to requiring flood coverage no greater than the outstanding mortgage balance, so the amount your bank asks for may not be enough to rebuild.

We write new NFIP policies through Selective, and we also quote private flood options such as Neptune Flood, Beyond Floods, Flow Flood, Aon Edge, CatCoverage and The Flood Insurance Agency, which can offer different limits or terms. FloodSmart notes that NFIP policies cover building and contents separately with separate deductibles, that belongings kept in a basement are generally excluded, and that items outside the building such as decks, patios and landscaping are not covered (FloodSmart: buying a flood policy). Start with our flood zone check tool, look up your official map on the FEMA Flood Map Service Center, then ask for a flood quote or see our overview of flood insurance.

VE, Coastal A and AE zones

Massachusetts coastal flood maps use a few labels worth knowing. V zones are coastal high-hazard areas where base-flood waves reach three feet or more. Under the state residential code, a Coastal A Zone is the band landward of a V zone where breaking waves can still reach a foot and a half; its inland edge is the Limit of Moderate Wave Action when FEMA has drawn that line on the map (780 CMR 51, R202 definitions). AE zones farther inland flood with smaller waves. A house in a V or Coastal A zone faces stricter building rules and closer flood underwriting than one in an AE zone, even on the same street.

Rebuilding after a storm: Massachusetts rules that matter

Massachusetts adds its own requirements on top of FEMA’s. Under 780 CMR 51, section R322, the design flood elevation for new and substantially improved homes is the base flood elevation plus two feet in A zones and plus three feet in V zones and Coastal A zones. Heating, electrical and plumbing equipment generally has to sit at or above that height. In mapped coastal dunes, section R322.4 requires the bottom of the first-floor framing to be above the design flood elevation or the height set by the local conservation commission, and no less than two feet above the ground, on open pilings in most cases, with no enclosures beneath it.

Dunes are also protected under the Wetlands Protection Act. The state regulation at 310 CMR 10.28 presumes coastal dunes matter for storm damage prevention and flood control, and any work on a dune or within 100 feet of one must not harm its ability to move, its volume or its vegetation. In practice, a damaged house near a dune may need a conservation commission review before it can be rebuilt, and the new design may look quite different from the old one.

Those rules cost money that a basic dwelling limit is not built to pay. Ordinance or law coverage helps with the extra cost of meeting current code, and extended replacement cost adds a cushion when labor and materials jump after a regional storm. On the flood side, an NFIP policy includes Increased Cost of Compliance coverage, which FEMA describes as help paying to elevate, relocate, demolish or floodproof a building that a community declares substantially damaged, meaning repairs equal at least half its pre-damage market value, or repetitively damaged. FEMA notes that this claim is filed separately from the flood claim itself (FEMA: Increased Cost of Compliance).

Storms that shaped the Massachusetts coast

Coastal underwriting in Massachusetts still carries the memory of the Blizzard of 1978. The U.S. Geological Survey describes how spring tides, a stalled storm and hurricane-force winds produced record flood levels along much of the coast from Massachusetts northward on February 7, 1978, with property damage greatest along the Massachusetts coast north of Cape Cod and 54 lives lost across the storm (USGS report on the 1978 coastal flood). On January 4, 2018, a winter storm pushed the Boston tide gauge to a new record, beating the 1978 mark, and forced rescues from flooded homes and cars in Boston and other communities (AP via CBS Boston, citing NWS Boston).

The January 10 and 13, 2024 storms were a reminder that the risk has not gone away. The state’s Coastal Storm Damage Assessment Team documented flooding of low-lying roads and neighborhoods in 39 communities on January 13 alone, with moderate flooding reaching farther inland along the South Shore, Boston and the North Shore and damage to homes in Salisbury. Ponded flooding after the January 10 storm was recorded in places including Hull, Marshfield, Newburyport, Falmouth, Wareham and Edgartown (CZM Storm Team release, January 2024).

Some towns flood again and again. Scituate’s 2016 hazard mitigation plan counted 520 repetitive loss structures, among the most in the state, and noted that flood events damaging those properties had occurred on average nearly twice a year (Town of Scituate Natural Hazard Mitigation Plan, 2016). Carriers know these patterns, which is why the same house can get very different answers depending on its street.

Coastal Massachusetts, region by region

South Shore

From Hull and Cohasset down through Scituate, Marshfield, Duxbury and Plymouth, the South Shore faces the open Atlantic with no Cape to shelter it from nor’easters. Homes behind seawalls and on barrier spits such as Humarock deal with overwash, and flood coverage is a must in many neighborhoods. See our pages for Scituate, Marshfield, Hull, Duxbury and Plymouth.

North Shore and Cape Ann

Salisbury and Newburyport sit on low beaches and the Merrimack estuary, while Gloucester and Rockport mix rocky shoreline with harbor neighborhoods. Storm damage to Salisbury homes in January 2024 showed how exposed a low beachfront street can be. Our Newburyport, Salisbury and Gloucester pages cover local details.

Cape Cod

Cape homes range from capes and ranches tucked inland to cottages right on the bay or sound. Barnstable County is where wind deductibles and FAIR Plan placements are most common, so a careful look at the declarations page pays off. See our Falmouth and Chatham pages, and our Massachusetts second and vacation home page if the house is seasonal.

Martha’s Vineyard and the Islands

Island homes face open ocean on several sides, and repairs depend on ferries, barges and a limited pool of contractors, so rebuilding after a storm can take longer. Loss of use coverage, which helps with extra living costs while you are displaced, deserves attention, along with flood. Our Edgartown page has more.

Carriers we use for coastal Massachusetts homes

Potential company options for a coastal Massachusetts home include Andover, Chubb, Cincinnati, Concord Group, Foremost, Hanover, Liberty Mutual, National General, Openly, Plymouth Rock, Providence Mutual, Safety, Stillwater, Universal and Vermont Mutual, along with the FAIR Plan (MPIUA) when the voluntary market falls short. None of these is a sure fit for any one house. Each carrier draws its own lines near the coast, by town, distance to the water and construction, and some do not write homes on the Cape or the Islands at all, so the list that fits a Chatham cottage may differ from the one that fits a Gloucester colonial. Many companies require underwriting review and approval before they will offer on a coastal home, or require a higher wind/hail deductible. We shop the house across our 40+ carriers and tell you which ones offered, and why, before you choose.

Around the home policy, an umbrella policy adds liability protection, and our umbrella insurance calculator helps you size it. If you rent the house out, see our Massachusetts landlord insurance page; for a two-unit condex, our condex insurance page.

Coastal Massachusetts homeowner checklist

• Find your wind or hurricane deductible on the declarations page and work out what it means for your dwelling limit.
• Ask whether shutters, impact glass, reinforced doors or roof tie-downs could reduce or remove that deductible, and keep proof.
• Look up your flood zone and get an elevation certificate if you do not have one.
• Buy or review flood coverage before storm season; most NFIP policies start 30 days after purchase.
• Confirm ordinance or law coverage and an extended replacement cost cushion.
• Tell us about seawalls, docks, decks and outbuildings so nothing is assumed.
• For a seasonal house, plan winter heat, a water shutoff and regular checks, and mention any rentals.
• Photograph each room and the exterior every year and store the files off-site.

Frequently asked questions

Do I need a special policy for a house near the Massachusetts coast?

Usually not a special policy, but a more carefully built one. Most coastal homes go on a standard homeowners form with a wind or hurricane deductible added, plus a separate flood policy for rising water. What changes near the shore is how many carriers will offer, which deductible they require and how closely they look at the roof, the foundation and the distance to the water.

What is a mandatory wind deductible in Massachusetts?

It is a separate deductible that applies when wind, a hurricane or a named storm causes the damage. The Division of Insurance says carriers commonly require one in coastal parts of Bristol, Plymouth and Barnstable counties and on the Islands, and sometimes based on distance to the shore. It can be a fixed amount or a share of your dwelling limit, and it should be spelled out on your declarations page.

Is the Massachusetts FAIR Plan a bad option for a Cape Cod home?

No. The FAIR Plan, formally the Massachusetts Property Insurance Underwriting Association (MPIUA), is a legitimate insurer of last resort that wrote about a third of Cape and Islands home policies in 2023. It offers more basic coverage, so it makes sense to check the voluntary market first and look again at renewal. Its clearinghouse also helps move policyholders back to regular carriers through their agent.

Does my homeowners policy cover storm surge from a nor’easter?

No. Surge, waves and tidal flooding are flood, and standard homeowners policies exclude flood no matter what storm caused it. Wind that tears off shingles or breaks a window is generally a homeowners claim, subject to any wind deductible. For the water side you need an NFIP policy, which we write through Selective, or private flood coverage from options such as Neptune Flood, Beyond Floods, Flow Flood, Aon Edge, CatCoverage or The Flood Insurance Agency.

How long does it take for a new flood policy to start?

An NFIP policy generally takes effect 30 days after purchase. FloodSmart lists exceptions: no wait when coverage is bought with a new, increased, extended or renewed mortgage or changed at renewal, and a one-day wait when a property is newly mapped into a high-risk zone and the policy is bought within 12 months of the map change. Private flood waiting periods vary by company, so plan before a storm is in the forecast.

What do you need from me for a coastal Massachusetts quote?

The address, your current declarations page and a few facts: year built, square footage, roof type and age, heating system, foundation type, distance to the water, and how the home is occupied (year-round, seasonal or rented). An elevation certificate helps with flood. Request a quote. There’s no obligation to buy. Write to insure@portsmouthatlanticins.com, phone (603) 431-4020 or complete the request form on this page.
