Non-Local Inspectors
Third-Party Inspectors
In some jurisdictions, third-party agencies are used in place of having an in-house inspector. In some smaller towns, the municipality will contract out with a third party such as Bureau Veritas or Middle Department Inspection Agency. This is most common in the Mid-Atlantic region of the United States.
Quick stat. 674 third-party inspection agencies were identified in the study.
State Electrical Inspectors
State-wide electrical inspectors are be used in a variety of circumstances. In some states, such as Minnesota, the majority of electrical inspections within the state are required to be inspected by a state electrical inspector (with the exception of a few municipalities). Other states such as Alabama use state electrical inspectors for state-owned buildings only. State electrical inspectors can also be called out to inspect local inspections if called upon by a local AHJ, such as in Arkansas.
