By Jon Merwin, Founder and CEO
Merrimack is a town of homeowners. Of the roughly 10,840 occupied homes counted in the latest five-year Census survey, only about 1,200 are rented, about one in nine, compared with roughly one in four statewide (ACS B25003). That small renter population lives in a fairly narrow set of places: apartment complexes, attached townhouses and a handful of rented single-family homes. Each comes with its own insurance questions.
Portsmouth Atlantic Insurance, an independent agency owned by one family since 2005, operates from Portsmouth, NH (601 Islington St, Unit 206). We work with Merrimack tenants over the phone and by email, and with 40+ carriers to compare we can fit a policy to a lease requirement, a first apartment or a move out of a house you sold. Email insure@portsmouthatlanticins.com or phone (603) 431-4020.
Key takeaways
- The owner’s insurance on your building or complex protects the owner; your belongings and your own liability need a renters policy.
- About seven in ten Merrimack renter homes are in buildings of five or more units, and the 1980s is the most common decade of construction.
- About one in five Merrimack renter homes is headed by someone 65 or older, many with more to insure than a typical first apartment.
- NH law caps deposits and sets move-in and move-out deadlines; your move-in condition list matters for both the deposit and any claim.
- A renters form leaves out flood damage, so tenants near water buy contents-only flood coverage as its own policy.

A snapshot of Merrimack renters
Here is how the Census Bureau’s 2020–2024 survey estimates sketch Merrimack’s tenants. With only about 1,200 renter homes, margins of error are wide, so read these as rough proportions.
| Measure (ACS 2020–2024) | Merrimack renters | Source |
|---|---|---|
| Rented homes | About 1,200 of 10,840 occupied homes (about one in nine) | B25003 |
| In buildings with five or more units | About 830 (roughly seven in ten) | B25032 |
| In buildings with 20 or more units | About 470 (close to four in ten) | B25032 |
| In attached one-unit homes, such as townhouses | About 160 | B25032 |
| Built in the 1980s | About 450, the most common decade | B25036 |
| Built in 2010 or later | About 280 (close to one in four) | B25036 |
| Headed by someone 25 to 34 | About 390 (about one in three) | B25007 |
| Headed by someone 65 or older | About 260 (about one in five) | B25007 |
| Average people per rented home | About 1.8, against about 2.7 in owner homes | B25010 |
Two groups stand out. Young professionals, often working along the Everett Turnpike corridor, fill the larger complexes. Older residents who have sold a family house make up a meaningful share too, and they tend to bring furniture, art and jewelry that a starter renters policy is not built around.
The coverage pieces
| Coverage | What it does | How it plays out in Merrimack |
|---|---|---|
| Personal property | Pays to repair or replace your belongings after fire, smoke, theft, vandalism, wind or sudden water damage | A balcony grill fire in a neighboring unit leaves smoke damage through your apartment |
| Loss of use | Covers the added cost of living elsewhere when a covered loss makes your place unlivable | Your building is closed for weeks after a sprinkler line breaks in a cold snap |
| Personal liability | Defends you and pays when you are legally responsible for injury to others or damage to their property | Your washer hose splits and water runs into the unit below |
| Medical payments to others | Modest treatment bills for a guest hurt at your home, no matter who was at fault | A visitor turns an ankle on your townhouse steps |
Theft away from home is usually covered as well, so a bike taken from a car rack at a trailhead or a laptop stolen from a car is part of the policy, subject to the deductible and any category limits. Jewelry, watches, silver and collectibles often carry low built-in theft limits, which is why scheduling them matters. Our renters insurance overview and the renters insurance in NH page go deeper into the standard forms.
Apartment complexes and lease requirements
Most Merrimack renters live in professionally managed complexes, and many leases there require tenants to carry renters insurance with a stated liability minimum. A few points help a complex tenant get it right:
- Interested party versus additional insured. Managers commonly ask to be listed as an interested party, which means they are notified if your policy cancels. That is different from adding them as an insured, and the lease wording tells us which they want.
- Water from above and below. In a stacked building, water damage often starts in another unit. Your policy handles your own belongings and displacement; the other tenant’s liability and the owner’s building policy sort out the rest.
- Storage units and garages. Belongings kept in a complex storage cage or detached garage are usually covered, but theft from storage areas can carry its own conditions. Keep a photo list.
- Pets. Dog liability is part of personal liability on most renters policies, though some carriers limit certain dogs or a dog with a bite history. Tell us about your pets up front.
Renting a townhouse or a house
About 160 Merrimack renter homes are attached one-unit homes, often a townhouse owned by an individual inside a condominium association. In that setup three policies are in play: the association’s master policy on the shared structure, the unit owner’s own coverage, and your renters policy. Only the last one protects your belongings and your liability. Owners on the other side of that arrangement can read our condo insurance guide for New Hampshire.
If you are renting after selling a house, look at more than a basic contents limit. Replacement cost on your personal property, scheduled coverage for jewelry or art, and a liability limit high enough to keep an umbrella policy in force are all worth discussing.
Storms, lightning and power outages
Merrimack’s 2026 hazard mitigation plan update notes lightning strikes on homes and on Fire Station No. 1 on August 14, 2025, about three feet of wet snow from the March 13–15, 2023 storm, and a July 2024 microburst in neighboring Milford with winds near 95 mph (Merrimack Hazard Mitigation Plan Update 2026). Events like those bring down lines and trees across the area.
For a tenant, the practical issues are a power surge that damages electronics, food lost while the power is out, and a stretch away from home if a tree comes through the building. Sudden damage to your property is usually covered; spoilage from an off-site outage often is not, unless an add-on is available. Loss of use responds when a covered loss leaves your unit unlivable.
Flooding near the rivers and brooks
The plan maps floodplain beside the Souhegan and Merrimack rivers and Baboosic Brook, and it names streets with a history of flooding, including Island Drive, Wire Road, Brenda Lane and Baboosic Road (Merrimack HMP 2026). Garden-level apartments and ground-floor storage in those areas are the most exposed.
Renters can buy contents-only flood coverage without the building owner’s involvement. New NFIP business we write goes to Selective, and private markets such as Flow Flood and Beyond Floods are also available to compare. Search your street on FEMA’s flood map viewer, read how NFIP contents coverage works on FloodSmart, and see our flood insurance page.
New Hampshire deposit rules in brief
A New Hampshire landlord cannot collect a deposit larger than a month of rent (or $100 if that is more), according to RSA 540-A:6. That section also gives you five days from move-in to put any needed repairs in writing to the landlord. After you move out, RSA 540-A:7 sets a 30-day deadline for returning the deposit with an itemized list of any deductions. These rules sit outside your insurance, but dated photos and that move-in list help in both a deposit dispute and a claim.
Carriers for Merrimack renters
For Merrimack renters we commonly compare Concord Group, Andover, Safety, Vermont Mutual, Hanover, Liberty Mutual and Stillwater, among others. Pairing renters with your car insurance is usually easy to set up, and an umbrella can sit over both when your liability exposure grows.

Frequently asked questions
My Merrimack apartment complex has insurance. Why do I need my own?
The complex’s policy is written for the owner. It pays to repair the buildings and defends the owner when the owner is at fault. It does not replace your couch after a fire two doors down, and it does not defend you if your dog bites a neighbor or your bathtub overflows into the unit below. Those are the gaps a renters policy closes.
My lease says I must carry renters insurance. What limits should I pick?
Read the lease first: many require a minimum liability amount and ask that the property manager be listed as an interested party so they are told if the policy lapses. Beyond that, set the personal property limit from a quick room-by-room tally of what it would take to replace your things, and choose liability at a level that matches what you have to protect. We can match the policy to the lease wording.
I sold my house and now rent a townhouse in Merrimack. What changes?
Your homeowners policy ends with the sale, and the townhouse owner’s policy covers the unit they own, not you. A renters policy picks up your furniture, art and collections, plus your liability. If you kept valuable jewelry or silver from the house, schedule it, and if your liability limits on the old homeowners policy supported an umbrella, ask us to keep that umbrella in place on top of the new renters and car policies.
Is water from the Souhegan or Merrimack River covered on a renters policy?
No. Rising water from a river, brook or heavy rain is a flood, and standard renters forms exclude it. Contents-only flood coverage is sold on its own, either from the federal flood program, where we place new NFIP business with Selective, or from a private flood insurer. Expect a 30-day wait on most new NFIP policies before taking effect, so do not leave it until a storm is in the forecast.
What happens to my deposit when I move out in New Hampshire?
Under RSA 540-A:7, the deposit must come back within 30 days of the end of your tenancy, and any deduction has to appear on a written, itemized list limited to damage for damage beyond reasonable wear and tear. Whatever repair list you sent the landlord in your first five days, as RSA 540-A:6 allows, is your best evidence of what was already there.
Does renters insurance pay for food that spoils when the power goes out?
It depends on the policy. Spoilage from an outage that starts away from your apartment, like a downed line after a thunderstorm, is often limited or excluded on a basic renters form, though some carriers offer a modest add-on for refrigerated food. A lightning surge that damages your television or computer is a different question and is often covered as sudden damage to your property, subject to the deductible.
What do you need to quote renters insurance in Merrimack?
The street address and unit, the kind of building (complex, townhouse or a house), who lives with you, a ballpark figure for your belongings, any pieces worth scheduling, and whether you have pets. Request a quote. There’s no obligation to buy. Share those through the form on this page, at insure@portsmouthatlanticins.com, or by calling (603) 431-4020.
