What it is

A post-installation inspection is performed by your local building/electrical authority to confirm the work meets code before the system is signed off. A system health inspection, done by a technician, checks wiring, fuel connections, the pad, and the transfer switch on an existing unit without necessarily doing full maintenance.

When it's needed

• After any new standby generator installation — this one isn't optional.
• Before buying a home with an existing generator, to confirm it was installed to code.
• If you suspect prior work (by a previous owner or unlicensed installer) wasn't done correctly.

Process

• Scheduling with the local permitting authority for a code inspection, or with a technician for a voluntary check.
• Visual and functional review of wiring, fuel connections, and the transfer switch.
• A written report noting any deficiencies.

Cost factors

• Code inspection fees are typically set by the local permitting authority
• Voluntary technician inspections vary by scope and region

Limitations

A code inspection confirms the installation met code at the time — it isn't the same as an ongoing maintenance check and doesn't replace one.
