ADU Construction costs in Montana
Typical Montana range: $85,000 - $310,000 per unit. Adjusted for local labor and material costs. An estimate for planning - not a quote.
An ADU is a zoning project before it is a construction project. Setbacks, lot coverage, parking relief, owner-occupancy rules and utility capacity decide what can legally go on your lot, and they vary street by street.
Garage conversions read as the cheap route and often are, but the slab usually sits below the required floor height and lacks a moisture barrier, so the real scope includes the floor system most quotes leave out.
Utilities are the line item that surprises people: whether your existing panel and sewer lateral can carry a second dwelling, or whether you are trenching to the main.
Deep frost depth and heavy snow load shape everything structural here, from footing depth to ice-dam protection at the eaves.
What is included
- Zoning and feasibility review
- Plan sets and permit submittal
- Detached, attached and garage conversions
- Separate utility metering
- Kitchen and bath rough-in
- Final inspection and occupancy sign-off

ADU Construction questions in Montana
How much does adu construction cost in Montana?
Most adu construction projects in Montana land between $85,000 and $310,000, depending on scope, access and material grade. That is an estimated range for planning, not a quote - call (844) 624-3161 and we will scope your job properly.
Are the contractors you refer in Montana licensed and insured?
Yes. We only refer contractors carrying current licensing for their trade and active liability coverage.
Can I legally build an ADU on my lot?
That depends on your zoning, setbacks, lot coverage and utility capacity. Feasibility review comes first, before any design spend.
Do you pull permits?
Where the work needs them, yes - the contractor files and schedules inspections. Unpermitted work surfaces at resale and is far more expensive to resolve then.
How soon can someone come out?
That depends on the contractor's schedule - we tell you what we are told when we connect you. Larger builds depend on design and permitting, which is where most of the calendar goes, not the construction.
What areas around Montana do you cover?
Montana and the surrounding metro, through our national line. Call (844) 624-3161 with the address and the project and we confirm whether we have a contractor who can take it on.
