Rules for Properties in Unincorporated Areas
For properties in unincorporated areas of Marshall County, permits are required for septic systems (ISTS - Individual Sewage Treatment Systems) throughout the entire county. These permits must be obtained from the Water and Land Office prior to installation. All sewage systems require soil verifications and must be designed, installed, inspected, altered, and repaired by a Minnesota-licensed ISTS professional, with exceptions noted under MN Rules 7083. A minimum lot size of one acre is required for properties with a septic system, with adequate space for two drain fields.
While the search results primarily detail septic system requirements for unincorporated areas, it's important to note that general Minnesota state plumbing codes apply. According to the Minnesota State Plumbing Code (MSPC), permits are required for any installation, addition, extension, alteration, or replacement of a plumbing system. Separate utility permits are needed for outside underground sewer, water, or septic systems, or connections to municipal utility systems. The state Department of Labor and Industry also requires plan review and approval for plumbing systems serving the public or a considerable number of persons, which includes various types of commercial and multi-unit residential buildings.
