Sewer/Water Licensing in Key Largo CDP, Florida

Who Needs a License

Any person who contracts to construct, repair, or maintain public or private water supply systems, wastewater treatment systems, or sewage systems in Key Largo must hold a valid state license under Florida's construction industry regulatory framework. This includes work on potable water lines, reclaimed water systems, septic systems, and connections to municipal sewer infrastructure.

Under Fla. Stat. § 489.105, "contractor" means any person who undertakes to, offers to, or does construct, repair, alter, or improve any building or structure for others. Water and sewer work falls within the purview of construction licensing requirements.

How to Get Licensed

Florida regulates sewer and water contractors through the Construction Industry Licensing Board, established under Fla. Stat. § 489.107. To obtain a license:

1. Determine your classification. The state issues licenses for different contractor types. Water and sewer work typically requires a license as a Class A or Class B contractor, depending on scope and contract value.

2. Meet qualifications. Under Fla. Stat. § 489.113, you must demonstrate competency through examination and documented experience in the trade. Specific experience requirements vary by license class.

3. Apply through the state. Submit your application to the Department of Business and Professional Regulation (DBPR) Construction Industry Licensing Board. The board reviews applications, administers exams, and issues licenses.

4. Pass the required exam. You must pass the Florida Construction Industry Licensing Board examination covering trade knowledge, business practices, and law.

Applicants should contact the Construction Industry Licensing Board directly for current application procedures, fees, and exam schedules.

Local Requirements

In Key Largo CDP, permits for sewer and water work are administered through Monroe County rather than a separate municipal building department, as Key Largo is an unincorporated community within Monroe County.

Before beginning work, obtain a permit from the appropriate Monroe County permitting office. Local amendments or additional inspection requirements may apply under the Key Largo Municipal Code. Contractors should review this code for any local standards specific to sewer/water installations in the Key Largo area.

Contact the Monroe County Building Department for specific permit requirements and local code provisions applicable to your project.

Exemptions

Fla. Stat. § 489.103 exempts certain work from licensing requirements, including:

• Work performed by property owners on their own property (with limitations)
• Labor performed under the direct supervision of a licensed contractor
• Certain emergency repair work (subject to specific conditions)

Verify your specific work type against current exemptions, as they are narrowly construed.
