Florida Low Voltage Practice cheat sheet
Florida Low Voltage Practice · Keep the key ideas within reach.
Scope, Licensing Categories, and Registration Limits
Florida regulates electrical and alarm contracting under Chapter 489, Part II, F.S.; the Electrical Contractors' Licensing Board within DBPR governs certification and registration.
State certification (unrestricted statewide scope) categories include electrical contractor, alarm system contractor I, alarm system contractor II, and registered alarm system contractor; local specialty licenses are registration only.
Alarm System Contractor I scope: burglar alarm, fire alarm, CCTV, access control, and intercom systems, including low-voltage wiring incident to those systems.
Alarm System Contractor II scope: burglar alarm, CCTV, access control, and intercom systems - fire alarm work is excluded from Category II.
A registered contractor may work only within the jurisdiction(s) that issued the registration certificate; a certified contractor may work anywhere in Florida.
Certificate of competency holders must also hold the required local occupational license before contracting; the state certificate alone does not authorize business activity.
Fire alarm system work requires the appropriate alarm contractor certification plus compliance with NFPA 72 and local fire official permitting; a fire alarm permit is separate from the building permit.
Qualifying a business requires the qualifier to be a primary or secondary qualifying agent with direct supervision duties; a qualifier may not qualify more than one competing business without Board approval.
Exemptions from licensure include work by employees of a licensed contractor under supervision, and certain public utility or communications company personnel acting within their utility scope.
Florida Laws and Rules
DBPR disciplinary grounds under s. 489.533, F.S. include fraud, incompetence, abandoning a project, failing to obtain permits, and aiding unlicensed contracting.
Contracting without a required license is a criminal offense: first offense is a first-degree misdemeanor; subsequent offenses are third-degree felonies.
Written contract requirements for residential work include the contractor's license number, a description of work, and a statement of the buyer's right to cancel under the 3-day rule where applicable.
The notice of commencement and lien law framework sits in Chapter 713, F.S.; contractors must give the owner the required lien-law notice language before starting residential work.
Workers' compensation coverage is required for construction employers with four or more employees (one or more for certain trades); a stop-work order may issue for noncompliance.
Continuing education for certificate renewal generally requires 14 hours per biennium, including 1 hour each on workplace safety, business practices, and workers' compensation, plus code updates.
Florida's construction lien statute allows a lien for unpaid labor or materials; the contractor must record a claim of lien within 90 days of last furnishing and file suit within one year.
The Florida Building Code is adopted under Chapter 553, F.S., and local amendments must be approved through the state process; local jurisdictions may not adopt conflicting technical amendments without approval.

Chapter 1, FBC-Building establishes the permitting process, including submittal documents, plan review timelines, and inspections required before covering work.
The FBC applies to new construction, additions, alterations, repairs, and changes of occupancy; existing structures are addressed by the Existing Building Code volume.

NFPA 72 requires smoke detectors spaced at 30 ft maximum on smooth ceilings, with the first detector within 15 ft of the wall; spacing reduces with ceiling height and obstructions.
Notification appliance circuits must meet candela ratings per the audibility and visibility requirements; public mode fire alarm audible levels are typically 15 dBA above ambient.
Grounding and bonding: telecommunications and low-voltage systems bond to the building grounding electrode system per Article 250 and ANSI/TIA-607.
Access control and CCTV low-voltage power supplies must be listed, and Class 2 power supplies must not exceed the power limitations of Article 725 tables.
