A house on septic carries a second set of questions that the listing rarely answers. Is the system on file with the county? When did anyone last look inside the tank? Is the drain field healthy, or just dry this week? This checklist turns those questions into eighteen items, each tied to the Alabama Department of Public Health's onsite sewage rules or to EPA and extension guidance for buyers. Tick each one as the seller, the county health department or a septic contractor confirms it, and the box at the bottom lists what you still need and who to ask. It works on a phone at the property; nothing is sent anywhere.
The checklist
| Done | What to confirm | Who can confirm it |
|---|---|---|
| The house is on a septic system, not city sewer, and the seller can point to the tank lids and the field. (EPA homebuyer guide) | Seller | |
| An Approval for Use is on file. ADPH says the completed permit carries a diagram of how the system was actually installed. | County health department | |
| The system was permitted. Under rule 420-3-1-.33, evidence that a system went in without a Permit to Install on or after March 18, 1982 can lead the county to decline an evaluation. | County health department | |
| A receipt showing the tank was pumped in the last 3 years by a pumper licensed by the Alabama Onsite Wastewater Board. | Seller | |
| The history of failures and repairs, especially whether the drain field was ever moved or replaced. (Virginia Cooperative Extension) | Seller | |
| No bedrooms or living space were added after the system went in, or the system was enlarged to match. (Virginia Cooperative Extension) | Seller | |
| For an engineered system: the recorded covenant (ADPH form CEP-7) and what upkeep it requires of whoever owns the house. | County health department | |
| The liquid level was noted before pumping: not low (a sign of leakage) and no staining above the outlet (a sign of backup). (EPA) | Septic contractor | |
| Sludge and scum layers were measured and written down. (EPA) | Septic contractor | |
| The tank walls and the inlet and outlet pipes are sound. (EPA) | Septic contractor | |
| An effluent filter sits on the outlet side and was cleaned. Current ADPH rules call for one meeting NSF Standard 46; older tanks may not have one yet. | Septic contractor | |
| Lids and risers are watertight and secure against children and pets. The current rule wants risers at least 18 inches across over the inlet and outlet. | Septic contractor | |
| The distribution box sends an even share of flow to each line. (EPA) | Septic contractor | |
| The field was walked: no standing water, no sewage smell, no bright, spongy green stripes. (EPA) | Septic contractor | |
| For a pump system: the high-water alarm was tested. ADPH rule 420-3-1-.27 puts it on its own circuit, separate from the pump, and requires that it can be tested. | Septic contractor | |
| Nothing has been built, paved or parked on the field, and no trees or shrubs crowd it. (ADPH) | You, on the walk-through | |
| Whether a public sewer line is within 500 feet. If the system ever fails and can't be repaired under the rules, rule 420-3-1-.32 requires connecting to it. | County health department | |
| Whether your lender wants a county health department evaluation, and the pump-out receipt that has to come with it. | Lender |
Without JavaScript the boxes still tick, but nothing is totaled. Work down the table and note what's blank; the third column says who to ask.
When to work through it
The useful window is between a signed contract and the end of your inspection or due-diligence period, while you can still ask for repairs, a price change, or walk away. Ask your agent for the dates on day one. Records requests to the county can take time, and a septic contractor's calendar fills in spring, so start on the paperwork items, the first seven on the list, the same week the offer is accepted and book the tank opening right after.
The county health department for the property depends on where the lot is: Madison County's office is in Huntsville, Limestone's in Athens and Marshall's in Guntersville. ADPH says property owners and their agents, a category that includes real estate agents, can ask the local office for septic information, and anyone else can request a copy of a permit through the department's records request page. Your agent can usually make that call for you.

Who confirms what, and why it matters
The seller
Only the people who have lived with the system know when it was last pumped, whether a field was ever dug up and moved, and whether that bonus room over the garage was added after the tank went in. Virginia Cooperative Extension's buyer guide makes the point that a house enlarged without a matching system can overload it, and that the cost of fixing that belongs in the offer or the contingency list. Get answers in writing where you can.
The county health department
The county office holds the permit file. A system with an Approval for Use has an official diagram, which settles where the tank and lines really are. The file also shows whether a system was ever permitted at all. That matters because Alabama's onsite rules let the county decline to evaluate a system that appears to have been installed without a permit on or after March 18, 1982, and may require it to be brought into compliance or replaced.
A licensed septic contractor
The tank and field items, from the liquid level down through the pump alarm, need someone to open the tank. EPA's guide for new homebuyers lists what a septic inspection should cover: pumping records, the system's age, sludge and scum depth, leaks, signs of backup, the condition of the tank and its pipes, the drain field, and the distribution box. Ask whoever you hire to write the layer depths and liquid level on the report. Alabama's rules add a warning worth repeating: an inspection by a home inspector or a licensed septic professional is not done under the state's authority and does not mean the system complies with the rules. A clean private report is good news about condition, not a legal sign-off.
Your lender
Some loans call for a county health department evaluation of the existing system. The rules allow one when the owner or a lender representing the buyer or seller asks, and before it is completed someone has to show the tank was pumped within the last three years by an AOWB-licensed pumper. If the seller's last receipt is older, the pump-out has to happen first, so find out early.
Reading the gaps
- Missing paperwork is a reason to dig, not to panic. Older systems often have thin files. But a system with no permit, on a house with additions, deserves a closer look before closing.
- A low tank level, staining above the outlet, or a wet field point at a real problem. Bring the report to a septic repair contractor for a scope and price, and read the permit walkthrough, because field work in Alabama runs through the county.
- A pump system with an alarm that doesn't sound is a cheap fix that protects an expensive one. See pump and alarm service.
- A sewer main within 500 feet changes the long-term math: a system that fails beyond repair would have to connect.
For the inspection itself, start with septic inspections in Huntsville. When you're ready to book the tank opening, call the number on this page and we'll pass it to a licensed contractor who covers that county.

FAQ
Does Alabama require a septic inspection before a house sale?
The ADPH onsite rules do not make one automatic. The county health department evaluates an existing system when the owner or a lender asks, and many buyers hire a septic contractor to open and inspect the tank during the inspection period.
Can my real estate agent get the septic permit from the county?
ADPH says property owners or their agents, including real estate agents, can ask the local health department for septic information. Others can request a copy of a permit through the department's records request page.
