Ala. Code § 34-33-7
The State Fire Marshal's permit shall expire annually at midnight on September 30. At least 30 days prior, the fire protection sprinkler contractor I or II must submit a renewal application. A renewal fee must be submitted with the application. Failure to renew the permit prior to the expiration shall cause the permit to be null and void as of the expiration date, and it shall be unlawful under this chapter for any individual, partnership, corporation, association, or joint venture to engage in the business of installing, repairing, altering, adding, maintaining, or inspecting a fire protection sprinkler system without a valid State Fire Marshal's permit. The permit may be reinstated by making application as before, and payment of the fee; however, until such time as a new permit is issued, it shall be unlawful for the fire protection sprinkler contractor I or II to engage in installing, repairing, altering, adding, maintaining, or inspecting fire protection sprinkler systems.
