If you are performing residential electrical, plumbing, or HVAC work less than $10,000, a state license is not required, but you must contact the local building official or permit office regarding the local requirements.
"I am a Journeyman Plumber in Colorado. I have wanted to get my master license for a while, but having three kids it's been difficult with time. I found this course online and my employer backed me on taking it. I highly recommend this course."
