If you are selling or buying a house on a septic system around Tucson, someone has probably told you that you need a "septic certification." The word shows up in listings, in emails from agents, and in escrow instructions. It is not a separate product. It is the everyday name for the septic inspection done when a property changes hands, and the report that comes out of it. Here is what the term means in practice.
When someone says certification, they usually mean three things at once: a qualified inspector looks at the system, the inspector writes down what was found, and the report goes into the sale file so the transfer can move forward. The legal rule behind it is explained on our ADEQ septic inspection page, and we do not repeat it here. The inspection itself is described on our transfer inspection page.
In most Tucson sales the seller arranges it, because the seller is the one who has to show the system was looked at. Sometimes a buyer asks for their own inspection as well, especially when the first report is old or the buyer wants a second opinion. Agents often start the request, so if yours has mentioned it, they are likely expecting a quick call to schedule. For agents, we have a separate page at for realtors.
The report records what was found in plain terms so everyone reading it, including the buyer and the lender, can see what the system looked like on that day.
It does not promise how long the system will last. It does not fix anything. It is a snapshot of the system on the day it was inspected, and a good inspector will say so. If the inspection turns up a problem, a repair is a separate job, and our page on what fails a septic inspection explains the usual causes.
Pumping empties the tank. An inspection examines the system. They are not the same, and one does not replace the other. Sometimes the tank has to be uncovered or pumped so the inspector can see the inside, and that is scheduled alongside the inspection. If you only want to know about service, read our septic pumping page. And if you cannot find the tank, our guide on locating a tank lid will help before we arrive.
Tell us the address, the closing date if there is one, and whether you know where the tank is. Send any earlier reports or permit paperwork you may have. Clear the area around the lids so the inspector can reach them. A little preparation is the difference between a smooth appointment and a rescheduled one. If cost is on your mind, our cost page explains what drives it.
Keep the report with your closing papers. A seller should give a copy to the agent and the title company, and a buyer should file one for their own records, since it shows the condition of the system on the day it was looked at. If the report lists items to watch, such as a lid that needs replacing or a tank that was close to full, ask the inspector what they would do first and in what order. Some items are quick fixes done before closing, and some are better handled by the new owner after they move in. Either way, it helps to have the choice made in writing so nobody is surprised at the table.
