Title 5 inspections, explained

Everything Massachusetts property owners should know before a sale or transfer.

What is Title 5?

Title 5 is the Massachusetts state code that governs private septic systems. When a property served by a septic system is sold or transferred, state law generally requires a passing Title 5 inspection to confirm the system protects public health and the environment.
