What Arizona Homebuyers Should Know About Septic Inspections

If you’re buying a home in Arizona with a septic system, understanding the inspection process is essential. Septic systems operate differently from municipal sewer connections, and failing to properly evaluate them before closing can lead to expensive surprises. Here’s what every Arizona homebuyer should know about septic inspections, from state requirements to what’s involved in the process.

The ADEQ Transfer of Ownership Program

In Arizona, the Arizona Department of Environmental Quality (ADEQ) requires a specific inspection process whenever a property with an on-site wastewater treatment system (septic system) changes ownership. This is known as the Transfer of Ownership (TOO) program.

• The inspection must occur within 6 months before the sale.
• The seller is responsible for initiating the inspection process.
• The buyer must submit a Notice of Transfer after closing.

Purpose of the Inspection

A septic inspection ensures the system is functioning properly and meets current regulations. It protects buyers from inheriting costly repairs and helps sellers document the system’s condition at the time of sale.

What the Inspection Involves

The process is more thorough than a routine maintenance check. A licensed inspector will:

• Locate and uncover the septic tank lids.
• Measure sludge and scum levels.
• Inspect inlet and outlet baffles.
• Check for cracks, leaks, or corrosion in the tank.
• Examine the drain field for signs of failure.
• Conduct a flow test to ensure wastewater is moving properly.

Documentation and Reporting

Once the inspection is complete, the inspector submits a detailed report to ADEQ or the delegated county agency. The report typically includes diagrams, photographs, and maintenance recommendations. A copy should be provided to both the buyer and seller.

Common Issues Found During Inspections

• Damaged or missing baffles
• Excessive sludge or scum levels
• Cracks or leaks in the tank
• Root intrusion into pipes or the tank
• Saturated or failing drain field

Who Can Perform a Septic Inspection?

In Arizona, only inspectors certified by ADEQ or a delegated county program may conduct official Transfer of Ownership inspections. This ensures the inspection meets all regulatory standards and is accepted for property transfer.

Why Homebuyers Should Attend the Inspection

Attending the inspection allows buyers to see the system firsthand and ask questions about its condition, maintenance history, and future care. It’s an opportunity to learn about the system’s location, capacity, and specific features.
