A tenant moves out of a Kalispell rental in February, and the electric baseboard heat had been running non-stop through a hard freeze the whole month before — except the tenant assumed heat was included in rent, and the landlord assumed the tenant had set up their own electric account months ago. Nobody transferred anything. Now there’s a utility bill nobody planned for, and a dispute nobody wants.
Utility responsibility trips up more Montana landlords than you’d expect, mostly because there’s a common assumption that this is purely a matter of what the lease says — the same way it works in many other states. In Montana, that’s only partly true. The state’s landlord-tenant law actually assigns some baseline utility-related duties by default, and you need a specific written agreement to shift them.
Montana’s Default Rule: The Landlord Starts With These Obligations
Under the Montana Residential Landlord and Tenant Act, MCA §70-24-303, a landlord’s baseline habitability obligations explicitly include:
- Providing running water and a reasonable amount of hot water
- Providing adequate heat during the colder months
- Providing trash receptacles and arranging for waste removal, where applicable
This is a meaningful difference from states like California, where there’s no statewide default rule on utilities at all and the matter is left entirely to the lease. In Montana, the starting point under state law actually puts heat, hot water, and trash on the landlord’s side of the ledger — unless you and the tenant agree otherwise, in writing.
How You Can Legally Shift These Responsibilities to the Tenant
The same statute, MCA §70-24-303(3), allows a landlord and tenant to agree in writing that the tenant will take on the landlord’s default duties around trash, heat, and hot water — but only if that agreement is entered into in good faith, not as a way of evading the landlord’s underlying obligations. In practice, this means:
- The arrangement needs to be explicit and in writing in the lease, not just assumed or implied.
- It needs to reflect a genuine agreement, not a one-sided term buried in fine print designed to offload responsibilities the tenant didn’t realize they were accepting.
- Even after shifting responsibility, the underlying habitability standard doesn’t disappear — if a tenant genuinely can’t afford to keep the unit adequately heated because the utility was shifted to them, that can still circle back to a habitability question if the unit becomes unsafe as a result.
This is one of the more distinctly Montana aspects of managing a rental here. A lease that’s silent on who pays for heat doesn’t leave the question open the way it might elsewhere — Montana law fills that silence in the landlord’s direction by default.
What About Electricity, Gas, and Everything Else?
Outside the specific categories addressed by MCA §70-24-303 (heat, hot water, and trash), other utilities — general electricity beyond heating, internet, cable, and in many cases water and sewer service where they’re separately metered — are governed by whatever your lease says, similar to the pattern in most states. It’s common practice across the Flathead Valley for tenants to establish their own accounts for general electric and gas service directly with the utility provider, while heat-related obligations get more scrutiny given the statute above.
For water and sewer specifically, many single-family rentals bill the service to the property rather than splitting it per unit, and landlords often either absorb the cost or pass it through as a flat fee or usage-based charge — as long as the arrangement is clearly stated in the lease.
Why This Matters More in a Montana Winter
The heat provision in MCA §70-24-303 isn’t an abstract legal technicality here — it reflects a genuinely serious safety issue. A rental unit without adequate heat during a Flathead Valley winter isn’t just uncomfortable; it’s a habitability problem that can lead to frozen and burst pipes, extensive water damage, and a legitimate tenant complaint or repair-and-deduct claim under the same statute. We’ve written separately about preparing rental properties for the season in our guide to winterizing a rental property in the Flathead Valley — it’s a natural companion read to this one, since heat responsibility and winter preparedness are two sides of the same issue.
Where Self-Help Remedies Cross the Line
Here’s where utility responsibility intersects directly with the topic we’ve covered in what a landlord cannot do in Montana: regardless of who’s technically right in a billing dispute, a landlord cannot shut off or fail to maintain heat, water, or electricity as a way of pressuring a tenant — that’s a self-help eviction tactic prohibited under MCA §70-24-411, even if the tenant genuinely owes you money for a utility you covered on their behalf. The only legal path to recovering unpaid amounts is through the proper channels: a demand for payment, small claims court, or, if it’s serious enough, the formal eviction process. Essential utilities have to stay on throughout.
What Belongs in Your Lease
Given Montana’s default statutory rule, your lease should be explicit about:
- Whether heat, hot water, and trash remain the landlord’s responsibility (the default) or have been shifted to the tenant by written agreement
- Which other utilities (electricity, gas, water, sewer, internet) the tenant is responsible for setting up and paying directly
- How any shared or pass-through utility costs are calculated, if applicable
- The deadline for a tenant to transfer any utilities into their own name after move-in
- What happens to utility accounts at move-out, and what documentation is required to confirm accounts were properly closed or transferred
Sub-Metering and Shared Buildings
For multifamily properties without individually metered utilities, a fairly allocated cost-splitting method (based on square footage or another reasonable formula) can work, provided it’s clearly disclosed in the lease and applied consistently. Whatever method you choose, the same underlying rule applies: heat and hot water are Montana’s default landlord responsibility unless you’ve documented a good-faith agreement shifting that responsibility elsewhere.
Where Most Disputes Actually Happen
In practice, utility disputes cluster around two moments: move-in, when a tenant hasn’t gotten around to transferring an account they were supposed to take over, and move-out, when a departing tenant assumes an account will simply close itself and leaves an outstanding balance behind. A simple, effective habit: require proof that a tenant has opened any utility accounts they’re responsible for as a condition of receiving keys, similar to how we recommend handling renters insurance requirements, and build a specific utility transfer step into your move-out checklist.
A Quick Compliance Check for Your Existing Lease
If you’re not sure where your current lease stands, ask yourself three questions: Does it explicitly say who’s responsible for heat and hot water, or is it silent? If it’s silent, remember that Montana law fills that silence in your direction as the landlord, not the tenant’s. If you’ve shifted that responsibility to the tenant, is that agreement actually in writing, or just something you’ve always done verbally? And finally, does your move-in checklist confirm the tenant has actually opened any accounts they’re responsible for, or does it just assume they will? A surprising number of long-standing leases fail at least one of these three checks, simply because they were written before the landlord fully understood how MCA §70-24-303 actually works.
Why This Small Detail Causes Outsized Headaches
Utility responsibility doesn’t get nearly as much attention as security deposits or eviction procedures in most landlord conversations, but the disputes it creates — a surprise bill months after a tenant moves out, a tenant who feels blindsided by a shifted heat obligation they didn’t fully understand, a habitability complaint stemming from an underheated unit — are entirely avoidable with clear, statute-aware lease language from the start.
Keeping This Off Your Plate
Tracking which utilities are in whose name, verifying transfers at move-in, and following up on balances after move-out are exactly the kind of recurring, easy-to-deprioritize tasks that quietly cause problems for self-managing landlords, particularly with properties spread across Kalispell, Whitefish, and Columbia Falls. Our property management services handle this as a standard part of move-in and move-out processing, so utility responsibility is documented correctly under Montana law from the start.
