Water Conditioning Licensing in Duck Key CDP, Florida

Who Needs a License

Under Florida law, a person engaged in the business of installing, maintaining, or servicing water conditioning equipment must hold a license as a "water conditioning contractor." [Fla. Stat. § 489.105] defines this trade and establishes that work involving water softeners, filters, reverse osmosis systems, and similar equipment constitutes regulated construction activity requiring licensure.

Not all water-related work is covered. The scope is limited to the installation and servicing of conditioning systems themselves—not general plumbing or well work unless directly connected to a conditioning system installation.

How to Get Licensed

Florida regulates water conditioning contractors through the Construction Industry Licensing Board (CILB). To obtain a license:

  1. Meet qualifications: You must demonstrate competency through either trade experience or a combination of education and experience. [Fla. Stat. § 489.113] sets specific requirements for applicant qualifications and restrictions on practice.

  2. Pass the CILB exam: Contact the CILB (operated by the Florida Department of Business and Professional Regulation) to register for the water conditioning contractor examination.

  3. Apply to CILB: Submit your application, proof of qualifications, exam results, and required fees directly to the state board. The CILB issues the state license—not the town.

  4. Obtain local authorization: After receiving your state license, you must register with Duck Key CDP's Building Department to conduct business locally.

Reference [Fla. Stat. § 489.107] for the CILB's authority and licensing procedures.

Local Requirements

Water conditioning work in Duck Key CDP is subject to Monroe County permitting and the Duck Key Municipal Code. Duck Key Municipal Code governs local business licensing and construction requirements.

Contact the Duck Key Building Department to determine:
- Whether a local permit is required before beginning work
- Any local licensing or registration fees beyond state licensing
- Whether Monroe County has additional requirements for your specific installation

Duck Key is unincorporated and operates under county jurisdiction, so coordination between the town and Monroe County may be necessary.

Exemptions

[Fla. Stat. § 489.103] exempts certain work from licensure. Exemptions typically include:
- Work performed by the property owner on their own property
- Work performed by utility companies in their regular operations
- Certain incidental or minor repairs below a defined threshold

Review the statute directly to confirm whether your specific work qualifies for exemption.
