South Dakota, Charles Mix County Plumbing Permit Regulations and County Ordinances for Unincorporated Areas

Charles Mix County Building Permit Requirements

Charles Mix County, South Dakota, has established a Building Permit Ordinance (2015) that requires a building permit for any residential, agricultural, commercial, or industrial structure built or moved into the county. This also applies to remodeling, additions, and other improvements to existing structures. Permits are issued by the Director of Equalization Office. Applications can be mailed to this office, and permits can be issued by mail upon receipt of a properly prepared application and the required fee. A permit is valid for 180 days from the date of issuance, and construction must begin within this period. Failure to obtain a permit before commencing construction can result in a penalty of $100.

The provisions of the Building Permit Ordinance apply to the entire county, with the exception of any city or organized township that has its own established building permit program.

Unincorporated Areas

The Building Permit Ordinance explicitly states that its provisions apply within the unincorporated areas of Charles Mix County, South Dakota, including organized and unorganized townships. This excludes incorporated communities within the county that have their own building permit programs.

Plumbing Permit Specifics

While the county issues general building permits, plumbing work in South Dakota is regulated at the state level by the South Dakota State Plumbing Commission. South Dakota has adopted the Uniform Plumbing Code (UPC), with the most recent adoption being the 2024 UPC. Homeowners may be permitted to install plumbing in their own single-family residence or farmstead, provided they reside there or will reside there upon completion. This homeowner exception does not apply to commercial or rental properties, which must be serviced by a licensed South Dakota plumbing contractor.

Plumbing installations, even by homeowners, must comply with state plumbing codes and require inspections (underground, rough-in, and final) by a state plumbing inspector.

South Dakota Plumbing Legislation, Codes, and Guidelines

State Statutes and Plumbing Codes

The state of South Dakota regulates plumbing through South Dakota Codified Law (SDCL) Chapter 36-25. Under this authority, the state has adopted the 2024 edition of the Uniform Plumbing Code (UPC) as the foundational technical standard for plumbing systems. This adoption includes state-specific amendments and rules promulgated by the state commission to govern the design, installation, and maintenance of plumbing systems, including potable water distribution, drainage, waste, and vent systems.

Primary State Agency

The primary agency responsible for setting and enforcing these standards is the South Dakota Plumbing Commission. This commission, which operates under the South Dakota Department of Labor and Regulation, is tasked with administering state laws and regulations concerning plumbing, licensing plumbing contractors and plumbers, conducting examinations, and performing inspections of plumbing installations to ensure compliance with the adopted state code.
