This page covers ADU construction in Clifton, Maine: in-law apartments for parents, units in garages or other accessory buildings, and small detached cottages, in a town where 13.5 percent of the housing is held for seasonal use.
ADU Builders Bangor reads Clifton's Section 8.3.1, which allows a unit of at least 400 square feet and no more than 750 square feet or half the house, by code officer and plumbing permits, and settles the septic before a plan.
The figure to keep: a garage ADU with a kitchenette in Clifton averages $87,000 to $133,000, and a detached ADU with a full kitchen $153,000 to $224,000+. Each range averages many quotes and is not a quote for your lot.
Why Does Clifton Set Both a Smallest and a Largest ADU?
Clifton sets both a smallest and a largest ADU because Section 8.3.1 asks for 400 square feet with one bedroom, plus 120 for each added bedroom, and caps the unit at 750 square feet or half the house, whichever is smaller. Beside a modest cape, half the house is often the tighter limit, so we measure the home first.

- Ten-foot side and rear setbacks in every area
- Each unit tied to an approved septic system

What Towns Border Clifton on Our ADU Map?
See all 22 towns we serveWhat ADU Suits a Clifton Lot and Household?
An ADU, short for accessory dwelling unit, is a second, smaller home placed on a lot beside its main house, and in Clifton the person it is for usually picks its shape.
Detached Cottages on Clifton Lots
Detached ADUs in Clifton sit in an accessory building on the same lot, a form Section 8.3.1 names outright. State law also allows a new structure built mainly for the ADU, so we ask the code office how Clifton reads the two before anything is drawn.
The cottage can sit 10 feet from a side or rear line, while the front setback runs 50 feet along Route 9 or Route 180. Each unit needs its own tie to an approved septic system, which a licensed site evaluator designs on the state's form.
Apartments Over or Inside a Clifton Garage
Garage ADUs fit Clifton's rule closely, since the ordinance names an accessory structure such as a garage as a place for the unit. Residential buildings here may reach 35 feet, which leaves room for an apartment over two bays.
The half-house cap applies here too, so a garage unit beside a small home stays small. An older garage gets a structure check on its slab and framing before we promise anything upstairs.
In-Law Apartments for Clifton Parents
In-law apartments are built into the house or onto it, which suits the older homes of the GMA 1A village core, where Clifton's first settlement grew. A parent gets a separate door and kitchen, one wall away from the family.
That wall or floor is built as the fire separation the code requires between two homes, and a basement unit gets egress windows large enough to climb out of. Because one bedroom needs 400 square feet here, a small ell may need an addition to qualify.
What ADU Building Services Do We Offer in Clifton?
Clifton work tends to draw on three of them.
- In-law apartments for a parent nearby
- Units in a garage or accessory building
- Septic design backed by a site evaluation
Under Section 8.3.1, the code officer issues the building permit for an accessory residential unit, a plumbing permit goes with it, and no Planning Board review is needed. Clifton's code enforcement page posts the state's HHE-200 septic design application, and we file what the job requires while each decision stays with the town.
How to Get a Clifton ADU From Measurements to Move-In
Measure the house, then the lot.
We measure your home to find the half-house cap, walk the yard to the 10-foot side and rear lines, and read Clifton's 2017 rule beside the state law.
Settle the price before the work.
A written price comes first, a contract both of us sign covers any job over $3,000, the opening payment is held to one third, and a surprise found mid-job is priced on a signed change order before we go on.
Build it, pass inspection, walk it through.
We apply for both permits, the building one and the plumbing one, then build under the code officer's inspections and tour the unit with you before your first box arrives.
Who Are the Right ADU Builders in Clifton, ME?
The right ADU builders in Clifton, ME measure both size limits and confirm the septic before they price anything, since a unit that misses 400 square feet or passes half the house goes back to the drawing table. For a household planning around a parent, we favor an in-law apartment in the house, which keeps help one door away and builds on the heat and water already there.
Maine's ADU law lets an ADU go inside a house, onto it as an addition, or into a new building of its own, and it bars a town from banning ADUs across its whole shoreland zone. Clifton's 2017 text predates that rule: it leaves the Shoreland Management Area out and sets a 400 square foot floor above the state's 190, so we confirm both with the code office first.
Maine's home construction contract law puts any job above $3,000 on a written agreement both sides sign, and it caps the up-front payment at a third.
Where Does Clifton Allow an ADU, and When Does That Change?
Where does Clifton allow an accessory unit?
Clifton allows an accessory unit in all three growth management areas, inside a single-family house or in an accessory building on its lot. A mobile home cannot serve as the unit, and a unit cannot be added to one.
When does Clifton's owner-occupancy rule end?
Clifton's owner-occupancy rule, Section 8.3.1.5, ends on July 1, 2027, when the state's ban on such rules reaches every Maine town. Until then the town's rule may still apply, and we ask the code office how it is enforced today.
When can a Clifton unit set aside the lot size rules?
A Clifton unit can set aside the town's minimum lot size, road frontage and shore frontage rules under Section 8.3.1.7, though every other part of the ordinance still applies. It must also meet Maine's minimum lot size rules for septic systems, 12 MRSA 4807.

How Much Will an ADU Cost in Clifton?
An ADU in Clifton will cost $87,000 to $133,000 when it is a kitchenette unit in or over a garage, and $153,000 to $224,000+ when it is a separate cottage with full cooking. Both are averages across many quotes, a starting budget and never your number.
| Kind of ADU | Typical size | Average range |
|---|---|---|
| Garage ADU with a kitchenette | 400 to 600 square feet | $87,000 to $133,000 |
| Detached ADU with a full kitchen | 600 to 900 square feet | $153,000 to $224,000+ |
| In-law apartment on or in the house | shaped by the house | priced from a visit |
These Clifton ranges are pooled averages, never a bid for your property. They swing most on three points: a stand-alone unit or one in a garage, a full kitchen or a kitchenette, and fresh septic and well work or a connection to the house's. Land is never inside them, and a town request that surfaces after drawing gets its own written price.
What pushes a Clifton cottage to the high end?
A Clifton cottage climbs toward the high end when it needs a new septic system and well, a long trench back to the house, or a full kitchen. The foundation follows the ground, and the 750 square foot cap keeps size from driving the number far.
Is a unit over an existing Clifton garage cheaper?
A unit over an existing Clifton garage costs less only if a structure check finds the slab and the framing ready for a second floor. If it does not, a new garage built around the apartment is the steadier choice.
Why isn't there a Clifton in-law apartment price?
There isn't a Clifton in-law apartment price because the house decides the scope: the rated wall or floor between the homes, the plumbing route and, in a basement, egress and moisture control. A visit sets that price.
