 Inspectors: Multi-hats and Single-hats

One of the largest questions we face is in the evolution of the job of the electrical inspector. With increasing budgetary restraints, more and more jurisdictions are facing the need for what we call multi-hat inspectors, or inspectors who perform more than one type of inspection. These additional inspections range from building to plumbing to mechanical.

What % of jurisdictions use single-hat electrical inspectors?
If we look at the 3,938 jurisdictions as a stand-alone unit, the numbers change only slightly. For example, the city of Birmingham, Alabama, has 6 single-hat (electrical) inspectors, but they are one jurisdiction. Nationwide, 66% of these jurisdictions use multi-hat inspectors, while 34% use single-hat inspectors.
