Certificate of Authorization Requirements

All septic tank contracting activities must be conducted under the name authorized by the department. The structure of the business determines whether a certificate of authorization is required. If required, mail a completed DEP Form 4077, Application for Certificate of Authorization, supporting documentation and a $250 check or money order payable to the Florida Department of Environmental Protection (DEP) to the address listed above.

The following business structures require a certificate of authorization:

  • An individual offering contracting services under a fictitious name as defined by the Florida Department of State. The individual proprietor or a legal employee must be a registered septic tank contractor to qualify the business.
  • A business that is structured as a corporation, limited liability company, partnership, or association. All individuals who act on behalf of the business as contractors must be registered or master contractors. At least one of the principal officers, partners, or members must be a registered or master septic tank contractor.

Septic tank businesses structured as a sole proprietorship, operating under the owner’s legal name, are not required to obtain a certificate of authorization. To request exemption from the certificate of authorization requirement, please provide a written statement that your business is a sole proprietorship offering septic tank contracting services under the proprietor’s (registered septic tank contractor’s) legal name. 

Section 489.555(1), Florida Statutes, states, in part, “A registered contractor may not be the sole qualifying contractor for more than one business that requests a certificate of authorization.” Any business name change or change of qualifying septic tank contractor change must be accompanied by the appropriate supporting documentation from the Florida Department of State for the fictitious name, partnership, or corporation.
