About Us

Built on Craftsmanship, Not Shortcuts

Klein Electric LLC was started by two brothers who believed electrical work should be done right the first time. That same hands-on approach applies to every ADU and tiny home project we take on across Maine. Small structures still need solid electrical systems, and we treat each one with the same attention we give to larger commercial jobs.

How It Works

Our ADU Electrical Process

ADU projects move fast and involve multiple trades. Here is how we keep the electrical work on schedule and inspection-ready.

01Step 1

Site Assessment

We review the ADU layout, planned load requirements, and utility access before any work starts so there are no surprises mid-build.

02Step 2

Rough-In Wiring

Once framing is complete, we run all circuits, conduit, and service wiring before walls close. This stage needs to pass inspection, and we plan for that from the start.

03Step 3

Panel and Service Connection

We install and wire the panel, connect the service entrance, and size everything to handle the ADU's actual electrical load, including future needs.

04Step 4

Finish Wiring and Fixtures

After drywall, we return to install outlets, switches, fixtures, and any specialty items like EV charger circuits or exterior lighting.

05Step 5

Final Inspection

We walk through the completed work and make sure everything meets Maine electrical code before you hand over the keys.

Frequently asked

Common Questions About ADU Electrical Work

Common questions get answered quickly so the page feels more trustworthy before someone reaches out.

Q1

Does an ADU need its own electrical panel?

In most cases, yes. A detached ADU typically requires its own subpanel or separate service. We assess your setup and determine the right configuration for the structure and load requirements.

Q2

Can you work directly with my contractor or builder?

Absolutely. We coordinate with builders, general contractors, and project managers regularly. Clear communication between trades keeps an ADU project moving without delays waiting on electrical work.

Q3

Do tiny homes on foundations need permits for electrical work?

Yes. Any permanent ADU or tiny home on a foundation in Maine requires permitted electrical work. We handle the process and ensure the installation is ready for the required inspections.

Q4

What about tiny homes on wheels or mobile units?

Electrical requirements differ for mobile tiny homes. We can discuss what applies to your specific situation, including shore power connections or permanent hookups depending on how the unit will be used.

Q5

How far in advance should I contact you for an ADU project?

As early as possible. Rough-in work has to happen during framing, so we need to be scheduled before walls close. Reaching out early also gives us time to pull permits and plan the service connection.

Q6

Do you serve areas outside of Oakland, Maine?

Yes. We work throughout Maine, including Augusta, Waterville, Bangor, Winthrop, Freeport, and the Belfast and Rangeley areas. If you are unsure whether we cover your location, just give us a call.

Q7

Can you add an EV charger circuit to the ADU at the same time?

Yes, and it is much easier to run that circuit during the rough-in stage than after the walls are finished. We can plan for an EV charger, additional outdoor outlets, or other circuits as part of the initial scope.

Q8

What size panel does a typical ADU require?

It depends on the square footage, appliances, and whether the unit has electric heat. Most ADUs work well with a 100-amp subpanel, but we size based on actual load calculations specific to your project.
