What custom homes actually cost in southern Maine in 2026
Langone Site Services builds custom homes across southern Maine and New Hampshire — from York and Kennebunk on the coast to Rochester and the Lakes Region. Here's what current pricing actually looks like — with line-item honesty, not "it depends" vagueness.

- Basic tier: $270/sq ft. Contractor-grade finishes, standard cabinets, laminate counters, builder-grade fixtures.
- Mid tier (most common): $300/sq ft. Mid-range cabinets, quartz or granite counters, upgraded fixtures, LVP or engineered hardwood floors.

Why our pricing is higher than some quotes you'll see
Two reasons. First, we build to spec with no "what else will come up" surprises — our number is what you pay. Second, we self-perform site work on an owned fleet, which adds quality and timeline certainty but isn't always the lowest bid.
If a contractor quotes you $225/sq ft in southern Maine in 2026, ask what's missing. Usually: the foundation, the utilities, or the permit fees.

Frequently asked questions
What does a custom home cost per square foot in southern Maine in 2026?
Roughly $270 per sq ft for a basic spec, $300 for mid-grade, and $425–$600+ for premium and luxury finishes. A mid-spec 1,400 sq ft ranch with a 2-car garage and full basement lands near $535,000 all-in.
Does that price include the land and site work?
Site work, yes — excavation, driveway, septic or sewer tie-in, and utility runs are part of our number because we self-perform them. Land is not included; if you have not bought yet, read our land feasibility checklist first.
Is it cheaper to build one story or two?
Per square foot, two stories are usually cheaper — one foundation and one roof cover twice the living area. A two-story layout runs roughly 7% less per square foot than the same area in a single-story ranch.
Can you build on a sloped or wooded lot?
That is our specialty — we are an excavation company that builds homes. Clearing, ledge, retaining walls, walkout basements, and long driveways are priced up front after a site walk, not discovered as change orders.
