Maine Apartment Building Insurance: 5+ Units, Mixed-Use and Seasonal Rentals

Maine apartment buildings have to get through Maine winters. A brick block in Portland’s West End, a converted mill building in Biddeford or Lewiston, a multi-family on a hill in Bangor or a waterfront building in Rockland or Bar Harbor all deal with the same things: long heating seasons, heavy snow on the roof, ice dams, frozen pipes in a vacant unit, and on the coast, nor’easters and storm surge. Many buildings are also old, and some owners mix year-round tenants with seasonal or short-term rentals.

Portsmouth Atlantic Insurance is an independent agency based in Portsmouth, New Hampshire, just across the Piscataqua River, and licensed in Maine. We don’t have a Maine office, but we serve Maine owners by phone and online, and we work with 40+ carriers. Most of what we do is personal insurance. On the commercial side we write one focused area: habitational buildings, meaning apartment buildings and condominium association master policies.

2-4 units vs. 5+ units

Two- to four-family rentals

Most carriers insure a two-, three- or four-family rental on a dwelling or landlord policy (often a DP-3 form), which is personal lines. That’s true whether you live in one unit or rent them all. Our Maine landlord insurance page covers 1-4 unit rentals in detail.

Five units and up

At five units, most carriers treat the building as a commercial habitational risk, usually written on a commercial policy that combines property, loss of rents and general liability. A building with a store or restaurant on the ground floor often falls here even with fewer apartments. Underwriters look at:

• Year built and the dates of roof, electrical, plumbing and heating updates
• Heating type and fuel: oil, propane, natural gas, heat pumps, wood or pellet stoves
• Fuel tank age and location, especially older oil tanks in basements
• Construction type, sprinklers and distance to the fire department and hydrants
• Seasonal use, vacancy and any short-term rental units
• Loss history and how the building is managed

In Maine, the carriers we work with for 5+ unit habitational buildings include Safety Insurance, Concord Group, Vermont Mutual, Andover Companies and Providence Mutual. Which one fits depends on the building’s age, construction, location and loss history, and we compare them for you.

What a Maine apartment building policy usually covers

• Building coverage at replacement cost
• Loss of rents while units can’t be rented after a covered loss. Winter rebuilds in Maine can take longer, so the length of this coverage matters.
• General liability for slips on icy walkways, stairs and parking areas, and other common-area injuries
• Equipment breakdown for boilers, furnaces and heating systems
• Ordinance or law for code upgrades required during repairs
• Water and sewer backup, usually limited unless added
• Umbrella or excess liability; see umbrella insurance

Coverage forms and exclusions differ by carrier, and the policy itself controls.

Maine issues that shape the policy

Heating and frozen pipes

Freeze-ups are one of the most common winter claims in Maine rental buildings. A heating failure in a vacant unit, or a pipe in an outside wall, can freeze during a cold snap and flood the floors below once it thaws. Many policies have conditions about maintaining heat or draining the system in vacant buildings, so read them closely if a unit sits empty. Low-temperature alarms, leak sensors and annual boiler or furnace service help, and underwriters notice them.

Snow load and ice dams

Heavy, wet snow and repeated freeze-thaw cycles put real stress on older flat and low-slope roofs. Ice dams can push water under shingles and into top-floor units. Keep a plan for roof snow removal on low-slope roofs, keep gutters and roof drains clear, and keep records of roof work. Underwriters ask about roof age and condition on nearly every quote.

Older buildings and code upgrades

Portland, Lewiston, Biddeford, Saco, Bangor and Augusta have plenty of late-1800s and early-1900s buildings with old wiring and heating. When a damaged building is repaired, local code enforcement will require current code for that work. Ordinance or law coverage can help with those added costs. Pre-1978 buildings may also have lead paint, and renovation work in older rental housing must follow lead-safe rules, so ask how your liability policy treats lead.

Seasonal and short-term rentals

Some Maine owners rent a few units by the week in summer. That changes the risk, and many policies treat short-term rentals differently from year-round leases, so tell us exactly how each unit is used. Towns regulate this too. In Portland, for example, rentals of 29 days or less must be registered as short-term rentals each year, and the registration number must be posted in the unit and on online listings. Portland also caps how many short-term units a mainland building can have based on its total unit count (for example, no more than five in a building of 10 or more units), and limits non-owner-occupied short-term rentals citywide. Check your town’s rules before listing. Source: City of Portland, Short-Term Rental Registration.

Coastal wind and flood

Buildings in York County, along Casco Bay and up the Midcoast face nor’easters, wind-driven rain and storm surge. Coastal policies may carry separate wind deductibles, and standard property policies exclude flood. Waterfront and riverfront buildings need separate NFIP or private flood coverage. See flood insurance.

Converted mills and historic blocks

Maine’s former mill cities have turned big brick mill buildings into apartments and mixed-use space. These buildings can be well built, but they’re large, with heavy timber framing, long open floors and sometimes historic designations that affect how repairs must be done. Replacement cost on a building like this can be far higher than its market value, so make sure the building limit reflects what it would take to rebuild, and review ordinance or law coverage with care.

Snow removal and slip-and-fall claims

Icy steps, walkways and parking lots are a steady source of liability claims for Maine landlords. If you hire a plow or shoveling contractor, use a written agreement, ask for a certificate of insurance showing the contractor’s liability coverage, and keep a log of when areas were plowed, shoveled and sanded. Those records help if someone falls. Higher liability limits or an umbrella are worth a look on larger buildings.

Loss of rents in a Maine winter

A fire in February doesn’t get rebuilt in February. Adjusting, permits, contractor availability and weather can stretch repairs well past what owners expect, and seasonal rental income lost in July can’t be made up later. Ask how your quote defines loss of rents (a set number of months, or actual loss sustained over a period), and whether it includes extra time to re-rent units after repairs.

What owners can do to make a building easier to insure

• Service heating systems every year and keep the records
• Replace older oil tanks and keep the replacement date on file
• Install low-temperature alarms and water leak sensors, especially in vacant or seasonal units
• Keep a snow and ice removal plan for roofs, stairs, walkways and parking
• Record roof, electrical and plumbing updates with dates
• Use written leases that require renters insurance

What to send for a review

2. Year built, construction, heating type and update dates
3. How each unit is used: year-round, seasonal or short-term
4. Current declarations page and renewal
5. 3-5 years of loss history

Frequently asked questions

When does a Maine rental building need a commercial policy?

Most carriers write 1-4 unit rentals on a personal dwelling or landlord policy. At five units and up, or with ground-floor commercial space, carriers usually treat the building as a commercial habitational risk.

Are frozen pipe claims covered in a vacant unit?

It depends on the policy. Many policies require you to maintain heat or drain the system when a building or unit is vacant. Read those conditions closely and tell us about any vacant units.

Can I rent some units short-term?

Possibly, but tell us exactly how each unit is used. Many policies treat short-term rentals differently from year-round leases, and towns such as Portland require short-term rental registration.

Is flood covered on my building policy?

No. Standard property policies exclude flood. Coastal and riverfront buildings need separate NFIP or private flood coverage.

Which carriers do you work with for Maine apartment buildings?

For 5+ unit habitational buildings in Maine, the carriers we work with include Safety Insurance, Concord Group, Vermont Mutual, Andover Companies and Providence Mutual.

Do you have an office in Maine?

No. We’re based in Portsmouth, New Hampshire, and we serve Maine owners by phone and online. We’re licensed in Maine and we don’t charge any fees.

Do I need loss of rents coverage?

If rents pay the mortgage, it’s usually important. It helps replace rental income while units can’t be rented after a covered loss, up to the policy limits.
