Water Conditioning Licensing in Marathon, Florida

Who Needs a License

Under Florida law, any person who installs, maintains, or services water conditioning equipment—including water softeners, filters, and treatment systems—must hold a valid license if the work involves plumbing connections or modifications to a potable water system. [Fla. Stat. § 489.105] defines water conditioning as a regulated trade within Florida's construction industry licensing framework. If your work is limited to selling or servicing equipment without system installation or alteration, you may fall under an exemption; however, most hands-on installation work requires licensure.

How to Get Licensed

Water conditioning contractors in Florida must be licensed through the Construction Industry Licensing Board under the Department of Business and Professional Regulation (DBPR).

Steps:

1. Meet qualifications under [Fla. Stat. § 489.113], which requires:
2. At least 4 years of experience in water conditioning work within the 10 years preceding application, OR
3. A high school diploma/GED plus an apprenticeship program completion, OR

4. An associate degree in a related field plus documented experience

5. Pass the DBPR-administered state exam covering water conditioning installation, maintenance, and safety codes.

6. Submit your application to the DBPR Construction Industry Licensing Board with proof of experience, exam passage, and applicable fees.

7. The board will issue your license upon approval.

Contact the Florida Department of Business and Professional Regulation for current exam dates, fees, and application procedures.
