How Does a Septic Inspection Work in Elizabeth and Elbert County, Colorado? – Marjorie Engle

If you’re buying or selling a home in Colorado’s Elbert County or Douglas County, how does the septic inspection process actually work, and what do you need to know before closing?

In Colorado, a septic inspection for a home sale involves a certified inspector locating your system, opening the tank, testing flow to the leachfield, and submitting results to the county so a “use permit” can be issued before the property transfers ownership.

Why Septic Inspections in Colorado Matter Right Now

If you’re looking at homes for sale in Elizabeth, Kiowa, Franktown, or anywhere across Elbert County, there’s something you need to understand: the overwhelming majority of these properties are on septic systems, not municipal sewer. The same is true for many homes on acreage in rural Douglas County, along the Monument corridor, and throughout the Colorado Springs foothills.

Colorado does not have a single statewide mandatory pre-sale septic inspection law, according to industry sources. Instead, every county writes its own transfer rules. That means the inspection process, who can perform it, and whether a permit is even required before closing all depend on which county line your property sits inside. As of 2026, 20 Colorado counties require a septic inspection when a home sells, per septictransfer.com.

What does that mean for you? It means you cannot assume the rules from Parker apply in Elizabeth, or that what your friend experienced selling in Highlands Ranch will match what you face in Kiowa. With 23 years in Colorado real estate and a specialty in wells and septic properties, I can tell you this is the number one area where buyers and sellers get caught off guard.

What Colorado’s “Use Permit” Process Looks Like in Elbert and Douglas Counties

Here’s the term you’ll hear constantly once you start the transaction: use permit. Both Douglas County and Elbert County call their septic inspection process a “use permit,” according to the Realtors Guide to Septic Inspections in Southern Colorado published by Septic Remedy. The use permit is generally good for 6 to 12 months depending on the county and allows the property to be listed and sold.

So how do you get one? You hire a certified inspector, they perform the inspection, and then the results get submitted to the county health department. If the system passes, the county issues the use permit. If it does not pass, repairs or replacement must happen before the permit is granted.

Who Can Perform the Inspection?

Not just anyone. Douglas County requires that use-permit inspections be conducted by a certified NAWT (National Association of Wastewater Technicians) inspector, per affordablesepticpumping.com. The county may reject reports completed by uncertified inspectors. El Paso County, which covers Colorado Springs and Monument, accepts inspectors who have passed the NAWT exam, the Colorado state exam, or, uniquely, El Paso County’s own exam.

What I tell my clients is simple: verify your inspector’s certification with the county before they set foot on the property. A rejected report means paying for a second inspection and losing time in your transaction window.

Step-by-Step: What Happens During a Colorado Septic Inspection

You’ve hired your certified inspector. Now what? According to the Realtors Guide to Septic Inspections in Southern Colorado, the process for a conventional gravity-fed system (the most common type in Elizabeth, Kiowa, and Franktown) includes these steps:

Locating the septic tank and removing the lids to access the interior
Identifying the tank type, whether concrete, poly, or metal (metal tanks are not allowed in Colorado)
Examining the lids and risers for structural integrity
Inspecting the tank interior for degradation such as cracks, root intrusion, or erosion
Checking inlet and outlet pipes and baffles to confirm they are intact and functioning
Verifying the presence of an effluent filter on the outlet baffle
Running a flow test by adding a minimum of 100 gallons to the tank and watching for proper flow to the leachfield
Probing the leachfield to check for excessive moisture, odors, seepage, lush vegetation, compaction, or surfacing wastewater
Inspecting the distribution box if accessible

If you have a pressure dosing system (common on some newer Elizabeth and Castle Rock acreage properties), the inspection includes additional steps for pumps, alarms, and dosing chambers.

Does that sound like a lot? It is. A thorough inspection typically takes a few hours, and the inspector will usually pump the tank during the process. This is why you should never schedule a septic inspection as an afterthought the week before closing.

Who Pays for the Septic Inspection in Colorado?

This is one of the most common questions I hear from both buyers and sellers across Elbert County and Douglas County. The answer: it is negotiable.

Traditionally in this market, sellers have handled the septic inspection and use permit as part of preparing the property for sale. That makes sense because the use permit is required before transfer, and sellers control access to the property. However, buyers sometimes take on the cost as part of their due diligence inspection, especially in competitive situations.

What I always recommend is getting the inspection done early. If you’re a seller in Elizabeth or Kiowa and you know your property is on septic, getting the use permit before you even list can eliminate one of the biggest negotiation leverage points a buyer will have. Rated 5 out of 5 stars by 118 past clients, I’ve guided sellers through this exact scenario many times, and proactive preparation almost always leads to a smoother closing.

What Happens If Your Septic System Fails Inspection in Colorado?

This is where things get real. A failed septic inspection does not automatically kill the deal, but it does create a significant decision point.

If the inspector finds issues like a cracked tank, failed baffles, a saturated leachfield, or a non-compliant system, the county will not issue the use permit until repairs or replacement are completed. Depending on severity, that could mean:

Minor repairs such as replacing a baffle, adding an effluent filter, or fixing a riser (often a few hundred dollars)
Moderate repairs such as replacing a distribution box or addressing minor leachfield drainage issues
Major work like full leachfield replacement or installing an entirely new system, which can cost thousands of dollars

Who covers the cost is, again, negotiable. In my experience, this is where having an agent who genuinely understands septic systems becomes critical. One of my past clients described exactly this dynamic: “She handled a very difficult inspection situation with the seller. Instead of letting it become stressful or discouraging, she protected our peace, advocated for us, and guided us through every step with calm reassurance.”

Having closed 138 transactions and specializing in wells and septic properties across Elbert County and Douglas County, I can tell you that the difference between a deal that survives a failed septic report and one that falls apart almost always comes down to how the negotiation is handled in the days immediately following.

Colorado County Septic Rules Vary, and That Matters for Your Transaction

Here is the part that surprises most buyers relocating from the Denver Metro suburbs. The state regulation governing all onsite wastewater systems is Colorado Regulation 43 (5 CCR 1002-43), issued by the Colorado Department of Public Health and Environment, Water Quality Control Commission. But the state sets only the floor. Each county writes the rest.

Elbert County (Elizabeth, Kiowa, Elbert, Franktown): Use permit required at transfer. NAWT-certified inspector required.
Douglas County (Castle Rock, Parker, Franktown areas): Use permit required. NAWT-certified inspector required, and the county may reject uncertified reports, per affordablesepticpumping.com.
El Paso County (Colorado Springs, Monument): Inspectors must pass the NAWT exam, the Colorado state exam, or El Paso County’s own exam.
Adams County: Use/transfer-of-title permit required in most cases. Inspectors must be NAWT- or NSF-certified, and in most cases the tank must be pumped, per the Adams County Health Department.

If you’re buying a property near the county line, say along the Franktown corridor where Elbert and Douglas counties meet, confirming which county your parcel sits in is step one. The rules, the forms, and even the approved inspector lists can differ.
