Hi, I’m Austin Williams, founder of Mod Septics.

When people think about buying or selling a home, septic systems usually aren’t top of mind — until something goes wrong. One of the most important steps I recommend during any real estate transaction involving a septic system is a septic system sale inspection.

I’ve seen too many buyers inherit costly problems and too many sellers get caught off guard late in the process. A proper inspection helps prevent both.

What Is a Septic System Sale Inspection?

A septic system sale inspection is an evaluation of the system during a property transfer. The goal is simple:
to confirm the system is functioning properly, accessible, and suitable for continued use by the next owner.

This isn’t just a quick look. A sale inspection focuses on system condition, visible components, and whether there are any red flags that could turn into expensive issues down the road.

How Sale Inspections Protect Home Buyers

From a buyer’s perspective, a septic system sale inspection is one of the smartest investments you can make.

A septic system is a major piece of infrastructure, and repairs or replacement can be costly. Without an inspection, buyers may take ownership of a system that is already failing, undersized, or poorly maintained.

A proper inspection can:

• Identify existing problems before closing
• Help avoid unexpected repair costs
• Confirm the system matches the home’s size and usage
• Give buyers confidence in what they’re purchasing

I always tell buyers: it’s much better to learn about a septic issue before closing than after.

Why Sale Inspections Matter for Sellers Too

Sale inspections don’t just protect buyers — they benefit sellers as well.

Knowing the condition of your septic system early allows you to:

• Avoid last-minute surprises
• Address issues on your timeline, not under pressure
• Support a smoother, faster closing
• Show transparency and good faith to buyers

In my experience, transactions go far more smoothly when septic questions are answered early.

LCRA Requirements: When a Sale Inspection Is Mandatory

In certain parts of Central Texas, septic system inspections aren’t just a good idea — they’re required.

Properties located within LCRA (Lower Colorado River Authority) jurisdiction, particularly near Lake Travis and the Highland Lakes, must complete an OSSF resale inspection whenever ownership changes.

These inspections are required to ensure septic systems are operating properly and protecting water quality and public health in sensitive areas.

This process includes specific paperwork, preparation requirements, and timelines. One of the most common issues I see is inspections being delayed because systems aren’t prepared correctly or requirements aren’t fully understood.

That’s why many homeowners choose to work with a septic professional who understands LCRA rules and can help guide the process from start to finish.

Who Should Have a Septic System Sale Inspection?

I recommend a sale inspection for:

• Anyone buying a home with a septic system
• Sellers preparing to list a property
• Homes that haven’t been inspected or pumped in several years
• Properties in environmentally sensitive or regulated areas
• Transactions involving LCRA or other regulatory authorities

Even when inspections aren’t legally required, they’re still one of the best ways to protect everyone involved.

My Bottom Line

Septic system sale inspections are about protection — for the buyer, the seller, and the property itself.

They provide clarity, prevent surprises, and help transactions move forward with confidence. Whether required by LCRA or simply recommended as a best practice, I believe sale inspections are a smart step in any septic property transfer.

If you’re buying or selling a home with a septic system and aren’t sure what’s required, my team and I at Mod Septics are always happy to help explain the process and make sure everything is handled the right way.
