Official Property Transfer Inspections You Can Trust

Across the Colorado Front Range, selling a property with an active On-Site Wastewater Treatment System (OWTS) requires a formal inspection prior to closing. At AB Septic, we provide the fully licensed evaluations needed to keep transactions moving smoothly.

As independent, certified NAWT Inspectors, our focus is providing an honest evaluation of the system's operational health. We deliver the structural findings required by local health departments to approve your county Use-Permit cleanly.

🏛️ Local County Regulations: What You Need to Know

Front Range counties enforce specific mandates during real estate transfers. We manage the technical paperwork to ensure closing compliance:

  • Boulder County: Requires a formal Property Transfer Certificate prior to closing. (Note: The county assesses a processing fee separate from inspection costs).
  • Jefferson County: Requires an official Property Transfer Acceptance document via JCPH before title transfer.
  • Weld & Adams Counties: Require transfer evaluations to be performed strictly by a National Association of Wastewater Technicians (NAWT) certified professional.

📋 Our Comprehensive Evaluation Protocol

A valid transfer inspection goes far beyond looking into an open lid. Our multi-point evaluation assesses every mechanical and structural component:

  • Locating, uncovering, and mapping the entire treatment layout.
  • Checking concrete integrity, dividing walls, and sanitary baffles for hydrogen sulfide gas corrosion.
  • Testing operational liquid levels, electrical alarms, control panels, and submersible pumps.
  • Examining absorption trenches to verify lateral line flow and rule out soil saturation.

Following testing, we provide an official findings report directly to you, your real estate agent, and the governing county health department.

If issues are identified, our technicians perform targeted septic component repairs, drain field restorations, structural tank replacements, and complete new septic installations.


Frequently Asked Questions

Can you sell a house with a failing septic system in Colorado?

Yes, typically via a Conditional Property Transfer. If an inspection reveals a failing system, counties permit closing if the buyer signs an agreement accepting responsibility to complete the required septic repairs or replacement within 365 days of closing.
