Gentlemen:
I am a licensed Electrical Contractor-Unlimited in Florida. I have been licensed in several states in the past. I have noted some discrepancies as to the qualifications that vary from state to state in my profession. 
Realizing that the Department of Health is responsible for licensing, under DBPR in Florida Statutes Chapter 404 (Section 404.056),  regarding Radon Inspection, mitigation and remediation these regulations should apply, as long as the standard applies to all doing business in Florida. Should a business entity wish to possess a license in Florida for this service, they must meet all qualifications for a license in Florida. There should be no “grandfathering” of any out-of-state business for Radon work of any kind unless it is proven that the out-of-state standard is either higher or equal to Florida’s qualification statute. This particularly applies to grandfathering. The state that the entity comes from may change their standard of qualifications. All qualifications for licensure must be met to comply with Florida Statute and regulation at the time of application for licensure in Florida and those qualifications must be equal to or greater than the entity coming from out of state. 
What I do not want to see is entities coming to Florida to take business from companies that do have to comply with business operations in Florida. 
Therefore I propose that any company coming into the state wishing to enter into business under a Radon license must operate under a licensed, legitimate business that already does business in Florida. Example: If a company wants to do business in Electrical Contracting Profession in Florida but possess no license to do so, would be able to hire a licensed contractor to be their representative on that particular project as a qualified business agent of the entity wanting to provide services in Florida. The same criteria should apply to out-of-state companies not directly licensed in Florida to provide Radon testing or Radon mitigation and remediation services. If a company wants to do business in Florida under their own business license, they should be required to meet all the obligations other resident businesses have to comply with. They must comply with all regulations to perform business services in Florida; licensure, insurance, etcetera.

I feel this is the only way to treat all businesses that operate in Florida fairly and on a level playing field.
