Inspector Certification Scope and Combination Designation
A municipality has adopted a certification program where an inspector holds a single 'Combination Inspector' credential covering building, plumbing, mechanical, and electrical. You are the newly hired inspection supervisor. The roster shows: Inspector A holds a Combination Inspector certificate plus a separate electrical inspector certificate. Inspector B holds only a Combination Inspector certificate but has 12 years of field experience and a state-issued electrical contractor license that lapsed 18 months ago. Inspector C holds a Combination Inspector certificate and has completed the required continuing education hours for all four trades, but the certificate card shows an expiration date that passed 45 days ago; renewal paperwork was submitted but not yet processed. Today's schedule includes a rough electrical inspection on a 200-amp residential service, a final plumbing inspection, and a mechanical rough-in.
1. Which inspectors may legally perform the rough electrical inspection today, and what is the reasoning?
Read the worked answer
Only Inspector A may perform the rough electrical inspection. The Combination Inspector certificate is the credential that authorizes electrical inspections; Inspector A holds that plus a separate electrical certificate, so there is no question of scope. Inspector B's lapsed contractor license is irrelevant - a contractor license is not an inspector credential, and field experience does not substitute for a current certificate. Inspector C cannot inspect anything today because the certificate has expired; a pending renewal does not restore authority until the jurisdiction issues or extends the credential. The practical rule: match the credential on the card to the trade being inspected, verify the expiration date is current, and do not let experience or a lapsed license fill a credential gap.
2. The jurisdiction's policy allows combination-certified inspectors to cross-trade inspect only where the certificate lists the trade. How should you handle the plumbing and mechanical inspections on today's schedule?

Read the certificate's trade endorsements literally. If the Combination Inspector certificate lists plumbing and mechanical, any of the three could perform those inspections - but Inspector C's expired card removes C from the pool, and Inspector B's lapsed license still does not matter because the combination certificate is the operative credential. The judgment point is that 'combination' is not a blanket authorization to inspect every trade; the endorsements on the credential define scope. Assign the plumbing final and mechanical rough-in to an inspector whose current certificate lists those trades, document the assignment, and pull Inspector C off the schedule until the renewal is processed. If no current inspector lists a trade, the inspection must be rescheduled or referred to a qualified inspector rather than performed by an unqualified one.
