Ala. Code § 34-33-3: Installation, Repair, Etc., of Fire Protection Sprinkler Systems - Conformity with Chapter Required.

Nothing in this chapter, however, shall be construed to apply to fire protection sprinkler system owners who employ registered professional fire protection engineers, and skilled workers who regularly and routinely design, install, repair, alter, add to, maintain, and inspect sprinkler systems on and within the premises of their employer, provided such systems are for the owners’ use only.
