Marco Island Plumber License Requirements (2026)

📋 Your checklist

State

1. Florida plumbing contractor license (DBPR CILB)
   Florida law says nobody may run a contracting business without being certified (statewide) or registered (local) in the proper classification. Plumbing contractor is its own classification. Unlicensed workers may only work under a licensed contractor's supervision.
   ⏰ Renew with DBPR each cycle, with continuing education (check the date on your license)

2. Business name and entity filings (Sunbiz)
   LLCs and corporations file an annual report ($138.75 for an LLC). Using a name other than your legal name? Register it as a fictitious name.
   ⏰ Annual report: May 1 ($400 late fee). Fictitious name: renew every 5 years

Local (Marco Island / Collier County)

1. City of Marco Island zoning certificate
   Get a city zoning certificate (home occupation or commercial) first; commercial locations also need a Marco Island Fire inspection. Whether the city issues its own tax receipt: verify.
   ⏰ One-time, per location
