- Who regulates septic permits
- For typical residential onsite systems in Iowa, regulation is primarily by local county boards of health or county environmental health offices, with Iowa DNR providing the state framework and handling larger public systems.
- Who can do the soil or perc test
- Iowa rules require a percolation test or soil analysis, and county permit pages reviewed here say applicants obtain that work from a qualified soil evaluator rather than county staff performing every test.
