Florida Septic Tank Contractor License Requirements: Complete 2026 Guide

Official-source review: August 25, 2026

Florida septic tank contractor license: Florida DEP calls the individual credential a Registered Septic Tank Contractor registration. The route requires three years or 6,000 hours of accepted experience, the registration examination, moral-character review, a state criminal-history check and a $100 application.

What the Florida septic tank contractor license covers

DEP separately regulates the individual and, for most business structures, the company name. Both must be active before offering services, and local permitting remains job-specific.

• Installation, repair, modification and maintenance of onsite sewage systems.
• Septic-tank pumping and abandonment when properly permitted.
• Individual work under active DEP registration.
• Business activity under an authorization certificate when required.
• Compliance with local permits and inspections.

2. Apply for and pass the contractor examination.
3. Request the FDLE record be sent directly to DEP.
4. Submit Form 4075 and the $100 fee.

Important Florida rules and boundaries

• A sole proprietor operating only under the owner’s legal name can qualify for the business-authorization exemption.
• A registered contractor generally cannot be sole qualifier for more than one authorized business.
• A state-licensed plumber is exempt from septic registration but must still follow all other DEP and permit rules.
• Unregistered contracting can lead to administrative and legal action.

Florida may separate the credential held by a worker from the contractor license held by the business, while preserving local authority over permits and inspections. Confirm every applicable layer before bidding, advertising or beginning regulated work.
