Cass County, North Dakota
Gardner is a city in Cass County, North Dakota. Septic permits inside Gardner come from the county and state together. 4 rules below are quoted from official sources and independently re-checked, most recently on November 6, 2026. Rules for unincorporated land are on the Cass County page.
Gardner does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.
Private sewage-treatment systems serving premises, including premises inside Gardner city limits.
public or noncommunity sewer availability distance: <= 200 feet (A premise used for human occupancy within this distance must discharge sewage into that system.)
“"Permit" means authorization from a local public health unit or other political subdivision [...] the department has the exclusive authority to adopt rules regarding licensing, permitting, and inspections of onsite wastewater treatment systems.”
Installation, addition to, or alteration of an individual sewage-treatment system at a building of human occupancy, including inside Gardner city limits.
“Where public or noncommunity sewage treatment systems are not available [...] previous to beginning any construction may be required to make application to the local or district health units for a written permit to make the desired installation.”
Human-waste disposal at premises inside Gardner city limits where water under pressure is not available.
“Where water under pressure is not available [...] approved privies, chemical toilets, or such other installations acceptable to the administrative authority.”
A premise used for human occupancy inside Gardner city limits, where a public or noncommunity sewage-treatment system is deemed available.
sewer availability distance: <= 200 feet (The premise must discharge sewage into the available public or noncommunity sewage-treatment system.)

We looked and could not find an official answer yet. Silence is not permission; ask Gardner or Cass County directly.
Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
Unanswered questions are usually a sign that Gardner publishes no rule on the point, not that none exists. Cass County’s page lists the county offices to call.
