Sewer/Water Licensing in Largo city, Florida

Who Needs a License

In Florida, any person who contracts to construct, repair, or maintain water or sewer systems must hold a valid license from the Construction Industry Licensing Board unless they qualify for an exemption.[^1] This includes installation, modification, and repair of potable water lines, wastewater collection systems, and related infrastructure.

The state defines regulated work under "water and sewer" contracting as work that affects public health, safety, and welfare through proper installation and maintenance of these critical systems.[^2]
