Not by law — but skip it at your own risk. A standard home inspection does NOT evaluate the septic system. Only a dedicated septic inspection opens the tank, checks the drain field, and tells you the system's real condition.
$300–$600 for the full inspection. Compare that to $15,000+ for a full system replacement — it's the cheapest insurance in the transaction.
