As of July 2006, Arizona law requires home owners with onsite wastewater treatment (septic) systems have their system inspected by a qualified Transfer of Ownership Inspector. The inspection report provides a full disclosure of the conditions of the septic system. The report does not guarantee compliance with codes, nor does it guarantee that the system will work in the future.

Inspection of a Cesspool

Once an inspector discovers a cesspool during an inspection, the inspection and report becomes one of full disclosure to the buyer and no longer qualifies as an inspection for the Transfer of Ownership program as ADEQ does not recognize cesspools as legitimate onsite wastewater treatment facilities. As a realtor, it is important to provide full disclosure to potential buyers. Any system that was installed prior to 1976 including but not limited to cesspools, homemade septic tanks, or other sewage disposal hybrid devices are grandfathered in until these "systems" fail or the residence plumbing is modified.  As always, check with Yavapai County Environmental Services for more information on your system.
