ADU Builder in Randolph, ME
Standalone and garage-integrated accessory dwelling units, full systems, sized to fit Randolph's compact riverside village lots.
An ADU in Randolph is a full second dwelling on your property: its own kitchen, bath, and systems, built as a standalone unit or worked into a garage. Around here that means fitting one onto a tight village lot, right across the Kennebec from Gardiner.
We check Randolph's zoning before any design work starts, so you know what fits before you spend money on plans. The owner walks your site in person first, whether it is a compact riverside lot or something with more room.
The same crew handles standalone and garage-integrated builds, and we give you a straight answer on cost and timeline up front.

Site work and foundation for a Randolph ADU
Foundation, framing, and full residential systems, plumbing, electrical, and HVAC, planned around Randolph's tighter village-lot setbacks and, near the water, shoreland drainage.
Standalone vs. garage-integrated in Randolph
Garage-integrated ADUs are often the better fit on Randolph's compact village lots, where a standalone build has less room to work with. Standalone units are still possible on the town's larger parcels.
Finish work and full systems
Full kitchen or kitchenette, bath, and finish work sized to the actual use. On these compact village lots the unit is usually a rental or an office.

Worth knowing
ADU builder in Randolph, ME
Randolph sits directly across the Kennebec from Gardiner, connected by the Randolph-Gardiner bridge, and its village lots are noticeably more compact than the surrounding rural towns. That tighter footprint is the biggest factor shaping an ADU plan here, more than anything else.
ADU zoning rules vary town by town in Maine and change more often than most other permitting categories, so we always confirm current Randolph rules rather than assuming a blanket standard. Properties near the Kennebec need shoreland zoning setbacks checked before we finalize a design.
Plan on 2 to 4 months minimum before groundbreaking, given the permitting and full residential-systems scope involved. On a tighter village lot, confirming setbacks early matters even more than usual.
Town of Randolph Code Enforcement requires a standard building permit for any new ADU, plus shoreland zoning review for properties near the Kennebec.
Maine does not license general contractors or builders, so ask to see photos of past ADU projects specifically, and ask whether a contractor has designed around tight village-lot setbacks near a riverfront before.

Tight village-lot setbacks near the Kennebec can limit which scope tier fits your Randolph property.
Does my Randolph property allow an ADU?
Randolph Code Enforcement handles this, and setbacks on these village lots run tighter than the towns around it. We confirm the numbers before we design anything.
Can I fit a standalone ADU on a small Randolph lot?
It depends on your setbacks. We walk the site first. Garage-integrated is often the better fit on tighter village lots here.
Can an ADU be built close to the Kennebec River in Randolph?
Yes, within shoreland zoning setbacks. We confirm the buildable scope and drainage plan before finalizing a design.
How long does an ADU build take in Randolph?
Expect at least 2 to 4 months of permitting ahead of groundbreaking, with construction time separate.
