Maximize Your Property's Living Potential

Turnkey service with design and permitting handled throughout

ADU Homes of Maine is a family-owned design-build contractor specializing in accessory dwelling units, tiny homes, and backyard living structures throughout Portland and surrounding areas. Whether you need space for aging parents, adult children, long-term guests, or caregivers, we create functional solutions that address Maine's evolving housing needs. Each project reflects a practical approach to expanding your property's capacity without sacrificing quality or comfort.



You'll work with one contractor from concept through completion, which means fewer coordination issues and more accountability at every stage. Design considerations, permitting assistance, site preparation, electrical, plumbing, roofing, and final construction all move forward under a single oversight structure. You can review downloadable floor plans and spec sheets to see what fits your space, then move into a consultation that addresses zoning, layout, and timeline.

Our commitment is grounded in craftsmanship and a straightforward process that respects both your investment and your property. Projects start at $157,500, with many homes completed in approximately 90 days depending on scope and conditions. ADU Homes of Maine helps homeowners turn underutilized land into purposeful, well-built living environments designed to last.

How Projects Move from Planning to Completion

You shouldn't have to manage multiple subcontractors or interpret conflicting timelines. Our turnkey model means one team oversees design, permitting, site work, utilities, and final assembly. Every phase is documented, and you'll know what's happening at each step—no guesswork, no gaps in responsibility. That level of coordination makes it easier to plan around the construction and understand what comes next.



We handle the details that often slow down backyard builds: zoning compliance, utility hookups, foundation work, and inspection scheduling. You receive updates as the project progresses, and any adjustments are discussed before they affect the timeline or budget.

Our approach is built to deliver homes that serve a clear purpose while fitting naturally into your property:

Customizable layouts sized between 400 and 1,000 square feet to meet local regulations and your specific needs

Complete oversight of electrical, plumbing, roofing, and finish work under one contractor's accountability

Assistance navigating permits and site preparation so the build starts on solid ground

Homes designed for Maine's climate and built to accommodate year-round living or seasonal use

Dependable Craftsmanship Rooted in Family Ownership

ADU Homes of Maine is a family-owned business, which means the people overseeing your project are invested in its outcome beyond the contract. We understand the properties in Portland and the surrounding region, and we recognize what it takes to build structures that hold up through Maine winters and evolving household demands. Our work reflects a long-term view—homes that function well now and remain practical years later.



Quality isn't an add-on. It's embedded in material selection, assembly standards, and how we finish each structure. You're hiring a contractor who shows up, follows through, and delivers what was agreed upon. That reliability extends to how we treat your property during construction and how we address questions or concerns as they arise.
