In Florida, electrical contractors must hold a license issued by the Department of Business and Professional Regulation (DBPR) Electrical Contractors' Licensing Board. The most common license type for residential and commercial work is EC (Electrical Contractor). You can verify a contractor's current license and status by searching the DBPR's online licensing portal by the contractor's name or license number.

Before hiring, ask your contractor whether their license covers the type of work you need—for example, an EC license permits general electrical installation, repair, and design. Check that the license is active and in good standing. The contractor should also be prepared to discuss permits; most electrical work in Florida requires a permit from your local jurisdiction, and your contractor should handle the permit application and ensure the work meets Florida Building Code requirements.
