Hello. To what degree (if any) can a homeowner perform their own
electrical and plumbing work in Massachusetts?

A new 200 amp service was installed (with the proper permit) by a
licensed electrician; can we install the new wiring for the house
interior without a permit?

Also wondering if all the plumbing can be done by the homeowner so
long as it's signed-off by a licensed plumber?


Here's a novel thought. Although, this might sound a bit crazy. Why don't
you ask your own building department?
