Here’s what you need to know if you’re buying or selling a home with a septic tank in Maryland.

Maryland recently passed House Bill 747 — Environment: On-Site Wastewater Systems – Inspection and Pumping Requirements. The law is scheduled to take effect June 1st, and it’s going to impact any property that uses an on-site septic system.

The goal is pretty simple: catch failing septic systems before a new homeowner inherits a very expensive surprise.

First — septic inspections can no longer be waived.
If a home is served by an on-site septic system, the system must now be professionally inspected as part of the property transfer.

Second — the septic tank may need to be pumped before settlement.
If the system hasn’t been inspected or serviced within the past three years, the law requires that the tank be pumped and evaluated by a licensed professional.

So if your home runs on septic, this is a big change in how transactions will work.

Bottom line:
If you’re buying or selling a septic property in Maryland after June 1st, plan for a septic inspection and possibly a pump-out before closing.

Real estate rules are always evolving — and knowing them ahead of time can save you a lot of surprises.

This is a critical update, Ellie! Dealing with septic systems is common in our mountain market here in Big Bear, so I know how vital these inspections are. Staying ahead of new legislation like HB 747 is exactly why clients need a pro like you.

Ellie McIntire I am normally not a fan of more rules and regulations, but I think this is a wise one.
