ADU Builder in Gardiner, ME
Standalone and garage-integrated accessory dwelling units, full systems, permitted for both Gardiner's historic downtown lots and its larger outlying parcels.
An ADU (accessory dwelling unit) in Gardiner is a second, smaller home on your property: standalone in the yard or built into a garage. Both come with full systems (plumbing, electrical, heat) so they work year-round.
Gardiner splits into two kinds of jobs. The tight, older lots downtown near the Kennebec need careful planning and historic-district know-how, while the bigger parcels toward West Gardiner give you more room to build.
We check local zoning before any design work starts, and the owner walks your site in person first so you get a straight answer on what fits, what it costs, and how long it takes. Same crew handles standalone and garage-integrated builds start to finish.

Site work and foundation for a Gardiner ADU
Foundation, framing, and full residential systems, plumbing, electrical, and HVAC, planned around whether your Gardiner lot is a tighter downtown parcel or a larger outlying property.
Standalone vs. garage-integrated in Gardiner
Garage-integrated ADUs often fit Gardiner's historic downtown lots better, where space is at a premium. Standalone units have more room to work with in outlying neighborhoods toward West Gardiner.
Finish work and full systems
Full kitchen or kitchenette, bath, and finish work sized to the actual use. Near Gardiner Common that often means a rental, further out it is usually family space.

Worth knowing
ADU builder in Gardiner, ME
Gardiner is a historic Kennebec River mill city, and its downtown lots around the Gardiner Common historic district are noticeably tighter and older than the larger parcels found toward West Gardiner. Which part of the city your property sits in changes what's realistic for an ADU more than almost 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 Gardiner rules rather than assuming a blanket standard. Downtown properties may also fall under historic district review.
Plan on 2 to 4 months minimum before groundbreaking, given the permitting and full residential-systems scope involved. Downtown properties should budget extra time for historic district review if it applies.
City of Gardiner Code Enforcement may require historic district review for downtown properties, in addition to a standard building permit elsewhere in the city.
Maine does not license general contractors or builders, so ask to see photos of past ADU projects specifically, and ask whether a contractor has worked within Gardiner's historic district review process before.

Downtown lots subject to historic district review can add time and design constraints versus outlying Gardiner properties.
Does my Gardiner property allow an ADU?
Zoning varies by district and changes often, so we confirm current rules with the city before we design anything.
Does my downtown Gardiner property need historic review for an ADU?
It can. We check whether your property falls within the historic district before finalizing a design.
Can I fit a standalone ADU on a downtown Gardiner lot?
It depends on the lot. Garage-integrated is often the better fit downtown; standalone units have more room in outlying neighborhoods.
How long does an ADU build take in Gardiner?
Expect at least 2 to 4 months of permitting ahead of groundbreaking, with construction time separate.
