Expert ADU Construction | At-Ease Contractors
At-Ease Contractors designs and builds accessory dwelling units for homeowners across Central Maine, managing every phase from site evaluation and permitting through foundation, framing, plumbing, electrical, and finished interiors on your property.
An ADU is not a guest room with its own entrance. It is a fully independent dwelling unit that has to meet every code requirement of a standalone home. That distinction changes the scope of the build entirely. At-Ease Contractors knows what it takes to get an ADU permitted, inspected, and livable in Central Maine.

Trevor was kind, responsive, and quick to take on my project. He made coordinating an appointment easy. He and his crew showed up on time and did a great job on my new garage.

A complete home on your property. Independent living space, built to code.
An ADU is a fully self-contained dwelling unit with its own kitchen, bathroom, entrance, and mechanical systems. The permitting, inspections, and construction scope mirror what goes into a new home build. We manage every detail from the first site visit forward.
Structural Evaluation and Code Requirements
We evaluate the existing structure to determine what stays and what changes. Foundation must support the new load. Walls need fire-rated assemblies. Egress windows, bathroom, kitchen, heating, and a separate entrance are all required. In Pittston and Randolph, we often find slabs poured without reinforcement.
The Most Complex Residential Work We Do
The structural and mechanical upgrades underneath the finished surfaces account for the majority of cost. Electrical, plumbing, framing, insulation, and final inspections all happen at separate stages. Each one has to pass before the next phase of work begins. We manage the full sequence.
Cost Range, Timeline, and What Drives Both
Basic conversions run 50,000 to 80,000. Full ADU builds with kitchen and separate systems range from 100,000 to 200,000 or more. Conversions take twelve to twenty weeks. New ADU construction reaches twenty to thirty weeks. The permit and inspection sequence alone sets the timeline.
We coordinate all permits, schedule every inspection, and manage the full project so nothing falls through the cracks on your property. Contact us to start planning yours.
