How many Florida-licensed plumbing contractors are active in Seminole County as of mid-2026?

Short answer: Roughly 950 to 1,100 — depending on the week and how you count.

Where the number comes from

The figure is from the Florida Department of Business and Professional Regulation (DBPR) public license lookup at myfloridalicense.com. The DBPR categorizes plumbing work under Certified Plumbing Contractor (CFC), codified in Florida Statute 489.131. We filter to records where:

• License status is one of Active, Current, or Active - Delinquent.
• Primary service county on file is Seminole (FIPS 12117).
• The license type is CFC (or successor categories added in the 2024 statute update), not Registered Plumbing Contractor (license code 'RP' — typically owner-occupied self-work).

What changes the count

• Renewal cycle: Plumbing license renewal runs in even-numbered years. The DBPR publishes a final-orders feed monthly; an unusually large disciplinary batch can move the count by 10-20 in either direction.
• Insurance licensure: Florida Statute 489.1155 requires workers' comp and general liability minimums. Residential plumbers whose policies lapse get an administrative hold during peak season, which the DBPR reports as delinquent.
• Practice scope: Roughly 8% of CFC license holders in the metro do commercial-only work; counting those changes the picture if you need residential-only contractors.

Cross-connection control notes (Florida Administrative Code 64E-6)

New residential service in Seminole County must pass a backflow prevention test per FAC 64E-6.009 and county ordinance §17.8. The proof of test is filed with Seminole County Utility's backflow tracking system within 10 days of the install date; failure to file freezes the property's water permit on subsequent resale. Plumbers who don't have a backflow-assembly-tester endorsement (BFE) on the CFC cannot sign the test; most do, but residential-only newcomers sometimes do not.
