State guide

North Dakota

North Dakota splits oversight: the Department of Environmental Quality licenses septic installers, while local public health units issue local permits and inspections before work begins. Several multi-county health districts publish their own onsite sewage program pages, and some link directly to the state installer list and the professional soil classifier roster.

Checked against official sources on October 4, 2026. Rules and links change; confirm with the office listed before you act.

What to do next

  1. Check which local public health unit serves your county before applying; several North Dakota programs cover multiple counties.
  2. If you are hiring a contractor, confirm both the DEQ installer license and the local permit requirements.
  3. Ask your local health program whether it needs a soil report, a professional soil classifier, or a local worksheet before permit review.
