Typical Maine range: $100,300 - $365,800 per unit. Adjusted for local labour 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.
Salt air plus freeze-thaw is the harshest combination for fasteners and coatings, so material choice matters more than it does inland.
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.

ADU Construction questions in Maine
How much does adu construction cost in Maine?
Most adu construction projects in Maine land between $100,300 and $365,800, 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 your Maine contractors licensed and insured?
Yes. We only refer contractors carrying current licensing for their trade and active liability coverage, and we re-check both before a referral goes out.
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?
For repair-scale work, usually the same week. Larger builds depend on design and permitting, which is where most of the calendar goes, not the construction.
What areas around Maine do you cover?
Maine and the surrounding metro. Call (844) 624-3161 and we will confirm your street - we usually do.
