Sewer/Water Licensing in Marathon city, Florida

Who Needs a License

In Florida, any person who engages in the business of installing, repairing, or maintaining potable water systems, wastewater systems, or irrigation systems must hold a valid license as a Water/Sewer Contractor or related classification under Chapter 489, Florida Statutes.[^1] The work is regulated because it directly affects public health and safety infrastructure.

This applies to contractors performing work in Marathon, Monroe County, Florida. If you install, repair, or maintain these systems for compensation—whether for residential, commercial, or municipal clients—you must be licensed.

How to Get Licensed

Licensing is administered by the Construction Industry Licensing Board established under Fla. Stat. § 489.107.[^2]

Steps:
1. Verify your eligibility under Fla. Stat. § 489.113, which establishes qualifications including work experience, financial responsibility, and knowledge of Florida construction law.[^3]
2. Complete required experience: For a Water/Sewer Contractor license, you typically need documented years of practical experience in the trade (specific hours vary by classification).
3. Pass the state examination: The Board administers licensing exams testing knowledge of construction codes, safety standards, and trade-specific regulations.
4. Submit your application to the Construction Industry Licensing Board with proof of experience, exam results, and any required documentation.
5. Obtain state licensure before performing any regulated work.

Consult the Board's current application requirements and exam schedules on the official Florida construction licensing website.
