This list includes Licensed Onsite System Inspectors/Evaluators who are authorized to inspect or evaluate onsite wastewater treatments systems (OWTS) for real estate transactions. Individuals are not licensed to perform regulatory functions, such as inspecting installation or repairs when an onsite system construction permit or a building permit is needed.

There may be additional requirements to work in some counties. Contact the county onsite sewage authority to confirm that an individual is authorized to inspect/evaluate onsite systems for real estate transactions in that county.

A Licensed Evaluator (EVAL) can only perform evaluations. A Licensed Inspector (INSP) can perform both inspections and evaluations. More information is available about inspections and evaluations.
