Do it yourselfers are hamstrung?

You're allowed to do your own plumbing/electrical if you're licensed for those trades in Hawaii. Of course, any previous non-Hawaii licensure you may have had in the past does not count here, and you can't get the required 2000 hours' apprenticeship unless you're related to a licensed electrician/plumber.

It would be "illegal" for someone to sign off work they did not perform.

Hooray for the State.
