On the first weekend of February 2023, Bangor city crews answered 22 frozen-pipe calls and five water main breaks, according to NewsCenter Maine's reporting on the cold snap. The wind chill at Bangor International Airport hit minus 47. Some of those calls came from rentals. Some of those owners learned what Maine law says about frozen pipes the expensive way.
Here is the short version. In Maine, a frozen pipe is your problem by default. The statute says so in plain words, the insurance policy you're counting on has a condition you may not be meeting, and the lease clause you think protects you may be void. I'm going to walk through all three, then show you exactly how we keep pipes from freezing in the units we manage.
This post is educational, not legal advice. Maine landlord-tenant law is particular, and the facts of your situation matter. For advice on a specific property or tenant situation, talk to a Maine-licensed attorney or contact Pine Tree Legal Assistance at ptla.org.
Who is responsible for frozen pipes in a Maine rental?
The landlord, in most cases. Maine's warranty of habitability says that when you are obligated to provide heat, failing to run the heating system "so as to protect the building equipment and systems from freezing" is a breach. Plumbing failures count as habitability problems. The main exception is damage the tenant caused.
The statute is 14 MRSA §6021, Maine's implied warranty and covenant of habitability. Every written or oral rental agreement in the state carries it. Subsection 6 sets out three ways a landlord who provides heat breaches it: the indoor temperature is low enough to injure health, the system can't hold 68°F in the unit when it is minus 20°F outside, or the heat isn't operated to keep the building's systems from freezing. That third test is the one that matters here. It's freeze protection written straight into the habitability warranty.
The 2025 session made this sharper. Public Law 2025, chapter 515, added a definition of "leaking event" to §6021 that expressly includes a failure of the plumbing system. It also added subsection 6-B, which makes it a breach to rent a unit where a leak or chronic moisture outside the tenant's control has produced mold. A pipe that freezes, splits, and drips into a wall cavity for two weeks before anyone notices is now squarely inside the statute.
Two limits work in your favor. A tenant can only bring a §6021 claim if the condition "was not caused by the tenant or another person acting under his control." And the court cannot award consequential damages under §6021, so the tenant's remedy is rent abatement, repair orders, or the right to move out during repairs with no rent owed. On a multi-week repair, that adds up.
What if the tenant pays for heat?
Subsection 6 is triggered "when the landlord is obligated by agreement or lease to provide heat." On a tenant-paid-heat lease, the statute's freeze test doesn't clearly reach you. Our view at BHR: act as though it does. The burst pipe still lands on your insurance claim.
What the lease can do is put the day-to-day temperature on the tenant. Subsection 6-A says a landlord is not responsible if a tenant who controls the thermostat turns the heat below 68°F, as long as the system itself can meet the 68°F capability test. For the full breakdown of who pays for fuel under different lease structures, see our post on who pays for heat in a Maine rental.
What does Bangor's code add on top of state law?
Bangor adopted the 2003 International Property Maintenance Code with local amendments. If you furnish heat, habitable rooms must reach 68°F from 6:30 a.m. to 10:30 p.m. and 60°F overnight. Code enforcement can order a building vacated if it loses heat or water, and buildings vacant 60 days must register.
The adoption is in Bangor Code Chapter 223, Property Maintenance. Three parts matter here.
- PM-602.3 sets the 68°F daytime and 60°F nighttime minimums for any owner who rents "on terms, either express or implied, to furnish heat." Bangor's text doesn't include a heating-season date range, so don't assume one.
- PM-109.1 lets the Code Enforcement Officer order the immediate vacating of a structure that loses its heat, water supply, or sewer service. A burst main in a basement can trigger it.
- Article II, the vacant building rules, requires registration and a fee within 60 days of a building becoming vacant, plus a placard with a 24-hour contact. Snowbird vacancies are exempt from registration but must be maintained by a property manager.
Here's the gap in the vacant building article. Section 223-11 requires the owner to protect the building "from deterioration by the weather," but it has no specific winterization standard. Your insurance policy fills that gap, and I'll get to it below.
If you own in Brewer, Orono, or Old Town, check those municipal codes separately.
Can a landlord charge a tenant for frozen pipe damage in Maine?
Yes, when the tenant's negligence caused the freeze and you can prove it. Maine law allows charges to recover reasonable repair costs for tenant-caused damage. It does not allow a lease clause that excuses your own negligence, and it doesn't let you bill a tenant for a freeze your heating system or insulation caused.
The governing rules are in 14 MRSA §6030. Subsection 2(A) makes any lease provision that "absolves the landlord from liability for the negligence of the landlord" unenforceable, and treats it as an unfair trade practice under 5 MRSA §207. Subsection 2(E)(3) expressly permits charges for "reasonable expenses incurred in the repair of damage to a dwelling unit caused by the tenant."
So the lease clause you want is narrow. The tenant keeps the unit at 55°F or above when they control the thermostat, reports any heating failure immediately, and is liable for freeze damage that results from failing to do either. The clause you don't want says the tenant bears all freeze risk, period. That one won't survive.
| What caused the freeze | Who usually bears the repair | Maine authority |
|---|---|---|
| Landlord-supplied heat failed or oil tank ran dry | Landlord | 14 MRSA §6021(6)(C) |
| Uninsulated pipe in exterior wall or crawlspace | Landlord | 14 MRSA §6021; §6030(2)(A) bars shifting it by lease |
| Tenant turned heat off or left windows open in a tenant-controlled unit | Tenant, if documented | 14 MRSA §6030(2)(E)(3); §6021(3) tenant-caused carve-out |
| Tenant-paid fuel ran out and tenant didn't report it | Likely tenant, depending on lease terms | 14 MRSA, §6026 if the condition was caused by the tenant |
| Vacant unit, owner kept no heat and didn't drain | Owner, and possibly no insurance coverage | Standard policy freezing exclusion |
Recovering the money usually means the security deposit. Under 14 MRSA §6033, you have up to 30 days on a written lease, or 21 days on a tenancy at will, to return the deposit with an itemized statement. Wrongful retention costs you double the amount withheld plus attorney's fees under §6034, and the burden is on you to prove the deduction was proper. Photos, the plumber's invoice naming the cause, and the thermostat setting at the time of discovery are what win that argument. Our guide to Maine security deposit law covers the itemization rules in full.
Can your insurer go after the tenant?
Only if your written lease clearly says so, based on the closest Maine precedent. In North River Insurance Co. v. Snyder, 2002 ME 146, the Law Court held that a residential tenant is not liable in subrogation to the landlord's insurer for a fire absent an express agreement in the written lease. That case was about fire, not freezing. No Maine decision I can find extends it to water losses, but I wouldn't bet a claim on the difference.
Is a landlord liable when a burst pipe ruins a tenant's belongings?
Usually not, unless you were negligent. Maine's general rule is that a landlord isn't liable for conditions inside premises the tenant controls, with three exceptions: a hidden defect you knew about, a repair you botched, or an express promise to keep the premises in repair. Otherwise, the tenant's renters insurance covers their stuff.
The rule comes from Nichols v. Marsden, 483 A.2d 341 (Me. 1984), and the Law Court reaffirmed it in Boles v. White, 2021 ME 49. Boles held that reserving a right to enter, inspect, and repair is not the same as an express agreement to maintain the premises. Common areas you control are a different matter. Section 6021 expressly includes them in the habitability warranty, and a basement supply line that freezes because the shared furnace failed is your problem.
Translate that into frozen-pipe facts. If you knew the kitchen line in the second-floor unit froze last January and you didn't insulate it, that's the latent-defect exception. If your handyman wrapped heat tape around a pipe and didn't plug it in, that's the negligent-repair exception. Either one puts the downstairs tenant's ruined couch on you.
The Maine Bureau of Insurance's homeowners and renters FAQ is plain about this: the landlord insures the building, and the landlord's policy does not cover the tenant's personal belongings. We strongly encourage renters insurance in every lease we sign.
Does landlord insurance cover frozen pipes in a rental?
Usually, for a sudden burst. But standard property forms exclude freeze damage unless you used reasonable care to maintain heat in the building or shut off the water and drain the system. In a vacant or unoccupied unit, that condition decides whether you have a claim or a five-figure bill.
The standard homeowners form excludes freezing while a dwelling is vacant or unoccupied unless you used reasonable care to maintain heat, or to shut off the water supply and drain the system and appliances. Dwelling-property forms, which is what most small landlords carry, apply a similar reasonable-care condition more broadly.
The Bureau of Insurance flags one more risk. An insurer may cancel mid-term if the insured property is vacant and custodial care isn't maintained. A vacant duplex nobody checks on is exposed twice: once to the pipe, once to the policy.
The dollars are real. The Insurance Information Institute puts the average homeowners claim for water damage and freezing at $15,400 for 2019 through 2023, and estimates roughly one in 60 insured homes files one each year. State Farm reported in January 2026 that its average frozen-pipe claim payment exceeded $30,000 from 2024 through mid-2025. Neither number includes lost rent while the unit is down, which your policy may or may not cover.
How do you prevent frozen pipes in a Maine rental?
Keep every unit at 55°F or warmer, or shut off and drain the water. Insulate or heat-tape pipes in exterior walls, crawlspaces, and unheated basements. Never let an oil tank run dry. Put low-temperature alarms in vacant units and basements. In Bangor, the average January night is well below the temperature where exposed pipes start to freeze.
The research benchmark most insurers use comes from University of Illinois Building Research Council field tests: uninsulated pipes in unconditioned space began freezing when it was 20°F or colder outside. Bangor's normal January low is about 9°F under the 1991 to 2020 normals, and the National Weather Service office in Caribou says Bangor averages eight nights below zero in January. Our normal January night is more than ten degrees past the alert line. Every exposed pipe in a central Maine rental is at risk every winter.
Heating oil: the dry-tank problem
Roughly half of Maine households heat primarily with fuel oil, according to the Maine Department of Energy Resources, the highest share of any state. Maine Public reported in September 2026 that heating oil had climbed to $5.77 a gallon. High prices mean tenants on tenant-paid-heat leases stretch deliveries, and stretched deliveries mean dry tanks on the coldest night of the month.
On a heat-included lease, a dry tank is a §6021(6) breach the moment the unit can't hold temperature. It also creates exposure under 14 MRSA §6014, which bars a landlord from willfully causing the interruption of heat or water, with actual damages or $250, whichever is greater, plus attorney's fees. My opinion: if you include heat, put every oil-heated building on automatic delivery. Will-call is how owners run out.
Heat pumps and the cold basement
Heat pumps are not the problem. The problem is what happens to the basement after you install one. Efficiency Maine's heat pump guidance warns that shutting off a boiler or furnace in a poorly insulated basement can raise the risk of frozen pipes. The old boiler heated the basement as a side effect. Take it offline and the sill-plate supply lines lose their only heat. If you've converted, you need insulation, heat tape, or a thermostatically controlled heater in that basement.
Our pre-winter checklist
Here is what we do on every building we manage before the first hard freeze.
- Service every boiler and furnace in September or October, with a licensed technician, and keep the service record in the property file.
- Confirm automatic delivery on every landlord-paid oil and propane tank, and check tank gauges on vacant units weekly.
- Walk every basement and crawlspace looking for pipes along exterior walls, sill plates, and fieldstone foundations, then insulate or heat-tape them.
- Close and seal crawlspace vents, basement windows, and any foundation gaps where cold air reaches plumbing.
- Disconnect garden hoses and shut off exterior sillcocks from the inside.
- Tag the main water shutoff in each building so a tenant, plumber, or our staff can find it in the dark.
- Install low-temperature and water-leak sensors in vacant units, utility rooms, and any basement that has frozen before.
- Send tenants written winter instructions: keep the heat at 55°F or above, report heat failures immediately, and open sink cabinets on exterior walls during cold snaps.
For routine inspections inside an occupied unit, give notice. 14 MRSA §6025 presumes 24 hours is reasonable notice and now carries a $250 minimum penalty for violations. A pre-winter pipe check is not an emergency. A burst pipe is.
Vacant units: heat it or drain it
Every vacant unit gets one of two treatments. There is no third option. Either the heat stays at 55°F or warmer and someone physically checks the unit on a fixed schedule, or a licensed plumber shuts off the water, drains the lines, and puts antifreeze in the traps. Both satisfy the reasonable-care condition in standard policies. Doing neither is how an owner ends up paying the full repair bill with no coverage. If the building has fire sprinklers, don't shut off the water without talking to your sprinkler contractor and insurer first, because draining can disable the system.
What should you do the moment a pipe bursts?
Shut off the water at the main, cut power to any wet electrical circuits, and get a licensed plumber in. You can enter without the usual 24-hour notice in a genuine emergency. Document everything before cleanup, call your insurer the same day, and restore water as fast as repairs allow, because utility interruption has its own legal rules.
- Shut off the main. If water is near the panel or outlets, kill those circuits, or call an electrician if it isn't safe.
- Enter the unit. Section 6025 waives notice "in the case of emergency," and an active leak or no heat in sub-freezing weather is the textbook case. Tell the tenant you're coming as soon as you reasonably can.
- Photograph and video the damage, the thermostat setting, open windows, and the fuel gauge before anything is moved.
- Call a licensed plumber. Ask that the invoice state the cause of the failure in writing.
- Notify your insurer the same day and start a water mitigation company drying the structure.
- Restore water and heat as quickly as the repair allows. Section 6014 permits temporary interruption while repairs are actually underway. It does not permit leaving a tenant without water for a week because the plumber is busy.
- Watch for mold for weeks afterward. Under the new §6021(6-B), mold from a leak outside the tenant's control is its own habitability breach.
If the unit is uninhabitable, Bangor's code enforcement can order it vacated, and the tenant has rights under §6021 to stop paying rent while repairs are made. Talk to your attorney before you discuss rent abatement or relocation with the tenant. Never use a burst pipe as an excuse to push someone out; that's an illegal eviction under §6014.
Frequently Asked Questions
Who is responsible for frozen pipes in a rental?
In Maine, usually the landlord. If you are obligated to provide heat, 14 MRSA §6021(6)(C) makes failing to protect the building's systems from freezing a breach of the warranty of habitability. A tenant who caused the freeze, for example by shutting off the heat in a unit they control, can be held responsible for the repair if you document the cause.
Can a landlord charge a tenant for frozen pipes?
Yes, if the tenant's negligence caused the damage. 14 MRSA §6030 allows charges for reasonable repair costs of tenant-caused damage, and you can deduct them from the security deposit with an itemized statement within the 30-day or 21-day deadline in §6033. You cannot charge a tenant for a freeze caused by your own failed heating system, and a lease clause excusing your negligence is void.
Is a landlord liable for frozen pipes damaging a tenant's belongings?
Only if the landlord was negligent. Under Nichols v. Marsden, a Maine landlord generally isn't liable for conditions in premises the tenant controls unless the landlord concealed a known defect, made a negligent repair, or expressly agreed to maintain the premises. Otherwise, the tenant's renters insurance covers their belongings. The landlord's policy covers the building, not tenant property.
What temperature should a vacant house be kept at in winter?
At least 55°F, which is the figure State Farm recommends to prevent freezing. The alternative is to have the water shut off and the system drained by a plumber. One of the two is what your insurer means by reasonable care. In Bangor, a building vacant for 60 days also has to be registered with the city under Chapter 223.
Does insurance cover frozen pipes in a rental property?
Usually, for a sudden burst in a building where heat was maintained. Standard forms exclude freeze damage in vacant or unoccupied buildings unless the owner used reasonable care to maintain heat or shut off and drain the water. Tenant belongings need the tenant's own renters policy. Read your specific policy's freezing exclusion and vacancy clause before winter, not after the claim.
Can a landlord enter a rental without notice to check for frozen pipes?
Only in an emergency. 14 MRSA §6025 presumes 24 hours' notice is reasonable for inspections and repairs, and a routine pre-winter pipe check needs that notice. An active leak, a burst pipe, or a no-heat condition in freezing weather is an emergency, and the statute waives notice in that case. Violations now carry a minimum of $250 in damages.
