Buffalo County, South Dakota Plumbing Permit Requirements

Instead, plumbing regulations and permit requirements are primarily governed at the state level by the South Dakota Plumbing Commission. For properties within unincorporated areas of Buffalo County, state regulations will apply.

South Dakota has adopted the 2024 Uniform Plumbing Code (UPC) as its standard. Homeowners in South Dakota may be permitted to perform plumbing work on their own single-family residences or farmsteads where they currently reside or will reside upon completion, provided they obtain a homeowner's permit. This exemption does not extend to other structures on the property. All plumbing work must adhere to the state plumbing code and is subject to inspection by a state plumbing inspector. Inspections typically include underground, rough-in, and final inspections, requiring advance notice.

Licensed South Dakota plumbing contractors are required for properties that do not qualify for the homeowner exemption. Contractor licensing in South Dakota involves meeting experience requirements, submitting an application with fees, and passing state plumbing exams. The state offers journeyman and contractor licenses.
