Florida has only one classification of inspector. It's called "standard inspector" (BN) with the particular qualifier such as electrical, plumbing, ect...
Plans examiners are the same. The classification is standard plans examiner (PX) with the particular qualifier.
The third classification is for the Building Code Administrator (BU) which is just the fancy name for the building official (CBO).
Then you have all the specialty licenses such as coastal construction, fire, energy, ect...
In my jurisdiction, we only have the electrical inspectors, electrical plans examiners, and an electrical division manager. A neighboring jurisdiction uses the classifications of Inspector I, II, III, and cheif.
