Add livable space, generate income, and keep family close. We build custom ADUs across NH and Southern Maine — from design and permits to the final coat of paint.
Accessory Dwelling Units are increasingly one of the smartest property decisions a homeowner can make. NH and Maine state laws have made them easier to permit and build than ever before.
Whether you're looking to generate rental income, create a private space for aging parents, accommodate adult children, or simply add value to your property — an ADU delivers on all fronts.
New Hampshire RSA 674:71–73 requires municipalities to allow at least one attached or internal ADU on single-family lots. Maine's LD 2003 (2022) and LD 1829 (2025) further streamlines the process, eliminating parking mandates and permitting detached units. We handle all permitting for you.
Offset your mortgage or build a passive income stream. A well-finished ADU in the Seacoast can rent for $1,200–$2,200/month.
Create private, comfortable space for aging parents or adult children — nearby but with their own independence and privacy.
ADUs consistently add more value to a property than they cost to build, making them one of the highest-ROI home improvements available.
Home office, artist studio, guest suite, caretaker unit — ADUs adapt to your life as your needs change over time.
Every ADU is designed on-site to integrate seamlessly with your existing home's exterior and style.
An addition connected to the main home sharing at least one wall. Most cost-effective — shares existing utilities and foundation.
A standalone structure on the same property — maximum privacy for both parties. Ideal for rental or independent living.
Convert an attached or detached garage into livable space. Most efficient path — structure already exists.
We walk your property, discuss your goals, and identify the best ADU solution for your lot, budget, and needs.
We handle all local zoning research, permit applications, and develop detailed plans tailored to your property.
Our crew begins construction — foundation, framing, roofing, and rough mechanicals (plumbing, electrical, HVAC).
Siding matched to your home, insulation, drywall, flooring, cabinetry, fixtures — every detail finished to spec.
We manage all required inspections and obtain your CO so the unit is legal, insurable, and ready to occupy or rent.
We walk every inch of the finished unit with you. Not complete until you're fully satisfied with the result.
