I am currently only inspecting in Missouri, but would like to move into Illinois as well. I have been trying to contact the Illinois Department of Professional Regulations, but it is impossible to actually speak with someone. I have a better chance of winning the lottery. I also have tried to look up the requirements online but there is sooooooo much conflicting information its unbelievable. Is there anyway someone could please help me or point me in the right direction to get certified in Illinois for home inspection as well as radon testing?
