Florida Plumbing Permits & Licensed Plumber Requirements Guide
In Florida, all non-exempt plumbing work requires a valid permit issued under the Florida Building Code (FBC), Plumbing Chapter 13. Only licensed contractors—Certified Plumbing Contractors (CPC), Certified General Contractors (CG) with plumbing scope, or Certified Plumbing Contractors (CFC)—may obtain permits and perform regulated work. Local jurisdictions enforce these statewide standards but may add supplemental requirements.
Permit Process & Jurisdictional Authority
Plumbing permits in Florida are issued by the local building department—county or municipality—and must comply with the Florida Building Code (FBC), 7th Edition (2020), incorporating the 2018 IPC with Florida amendments. A permit is required for new installations, replacements of fixtures, water heaters, backflow preventers, or any alteration affecting drainage, venting, or supply systems. Exemptions are narrow: minor repairs like faucet washer replacement or clearing stoppages do not require permits. Applicants must submit plans signed and sealed by a Florida-licensed design professional if structural modifications or system redesigns are involved. The permit application includes proof of contractor licensure (CFC, CPC, or CG), site plan, plumbing riser diagram, and product submittals. Fees vary by jurisdiction but typically scale with project valuation. Electronic permitting is widely adopted (e.g., Miami-Dade ePermit, Pinellas County Permit Portal), and most counties require pre-application coordination for commercial or multi-family projects. Failure to obtain a permit before work begins may result in stop-work orders, fines up to $5,000 per violation under Section 455.228, F.S., and mandatory re-inspection after demolition.
Licensing: CFC, CG, and CPC Requirements
Florida law mandates that only individuals holding a valid Florida Certified Plumbing Contractor (CFC) license—or a Certified General Contractor (CG) or Certified Plumbing Contractor (CPC) license with active plumbing scope—may pull plumbing permits and supervise regulated work. The CFC license is administered by the Florida Construction Industry Licensing Board (FCILB) and requires 4 years of documented plumbing experience, passing the state exam (covering FBC Plumbing, business practices, and trade knowledge), and $100,000 general liability insurance. CG licensees may perform plumbing only if their scope explicitly includes it and they meet the same insurance and bonding thresholds ($100k GL, $15k bond). All licensees must complete 14 hours of board-approved continuing education biennially, including 1 hour on Florida laws and 1 hour on workplace safety. Unlicensed activity is a third-degree felony under Section 489.127, F.S. Local governments may impose additional registration (e.g., Broward County’s Trade License) or require local qualifying agents for out-of-county firms. Subcontractors must be listed on the prime contractor’s permit and maintain current licensure verified via the MyFloridaLicense.com portal.
Inspection Stages & Compliance Milestones
Florida plumbing inspections follow a strict staged sequence defined in FBC Plumbing Section 105.5 and enforced locally. Required inspections include: (1) Rough-in (after piping is installed but before wall/drywall concealment), verifying pipe sizing, slope, venting, cleanouts, and support; (2) Drain-Waste-Vent (DWV) test (air or water, per FBC 312.2–312.3); (3) Water distribution pressure test (150 psi for 15 minutes minimum, no drop); (4) Final inspection (after fixture installation and connections). Backflow prevention devices require separate certification testing by a Florida-certified Backflow Prevention Assembly Tester (BPAT) prior to final inspection. Inspectors verify compliance with FBC Table 606.3 (pipe materials), Table 709.1 (vent sizing), and Section 1307.2 (water heater seismic bracing). Digital inspection scheduling is standard; missed appointments incur rescheduling fees and delay certificate of occupancy. Re-inspections due to failures require corrective documentation and may trigger third-party verification for repeated deficiencies. Counties like Hillsborough mandate pre-inspection checklists signed by the CFC before scheduling.
Backflow Prevention & Water Heater Requirements
Florida mandates backflow prevention per FBC Plumbing Section 608 and Chapter 62-550 F.A.C., requiring Reduced Pressure Principle (RP) assemblies for high-hazard connections (e.g., irrigation with fertilizer injection, fire sprinklers) and Double Check Valve Assemblies (DCVA) for moderate hazards (e.g., boiler systems). All assemblies must be installed above grade, accessible, and tested annually by a Florida-certified BPAT—with reports filed electronically via the Florida Department of Environmental Protection’s Backflow Prevention Program. For water heaters, FBC Section 507.2 requires temperature and pressure relief (TPR) valves discharging to an approved location (within 6 inches of floor, terminating in plain sight), plus seismic bracing per ASCE 7-16 for installations in Seismic Design Category C or higher (all of Florida). Gas water heaters require combustion air provisions per FBC 1307.2. Electric units must comply with NEC Article 422.13 and GFCI protection where installed in garages or unfinished basements. Tankless units require dedicated gas lines sized per manufacturer specs and FBC Table 2403.2. Non-compliant installations fail final inspection and may void manufacturer warranties.

Can a CG contractor legally install a tankless water heater without a CFC endorsement?
No. Under Florida Statute §489.105(7)(a), a CG contractor may only perform plumbing work if their license scope explicitly includes plumbing and they possess the requisite experience, insurance, and bonding. Installing a tankless water heater constitutes regulated plumbing work requiring either a CFC or a CG with plumbing scope—and the work must be supervised by the licensee named on the permit.
Do I need a permit to replace a residential water heater in Miami-Dade County?
Yes. Miami-Dade County requires a plumbing permit for all water heater replacements—even like-for-like—per its Supplemental Requirements to the FBC. The permit must be pulled by a CFC or qualified CG, include seismic bracing calculations, and pass both rough-in and final inspections. Temporary installations without permits are prohibited and subject to enforcement under Miami-Dade Code §13-12.
Is annual backflow testing required for a single-family home with an irrigation system in Orlando?
Yes. Orange County requires annual testing of all backflow prevention assemblies—including those serving residential irrigation systems—per Chapter 15-128, Orange County Code, which adopts F.A.C. 62-550. Test reports must be submitted electronically to the county’s Backflow Program within 30 days of testing and retained for five years.
