Grant County Building and Safety Regulations
Grant County, South Dakota, handles building permits through its Planning & Zoning Office. This office administers county zoning ordinances and processes applications for building permits. For properties in unincorporated areas, the Grant County Planning & Zoning Office is the primary point of contact for permit requirements. They adopt and enforce the 2021 International Building Code (IBC) as their standard for new construction.
HVAC work, like other mechanical systems, generally requires a building permit in South Dakota, with local jurisdictions defining the specifics. While South Dakota does not have state-level HVAC licensing, individual cities and counties may have their own licensing requirements.
Rules for Properties in Unincorporated Areas
For properties located in unincorporated areas of Grant County, the County Planning & Zoning Office is responsible for issuing building permits. This includes permits for new residential structures, garages and sheds larger than 79 square feet, building additions, decks, demolition, and moving existing structures.
It is important to note that even if a property is tax-exempt, such as farm residence properties, new structures on these properties are still subject to permit requirements.
Electrical and plumbing work, which would include HVAC systems, requires a state-licensed contractor regardless of project size.
Applications for building permits in Grant County should be submitted to the Planning & Zoning Office at 210 E 5th Avenue, Milbank, SD 57252. A site plan drawing showing property lines and the proposed structure's location is mandatory. For new construction, a property sketch is also required.
Permit applications are available daily, and approval is granted by the Planning & Zoning Officer after review. It is recommended to submit applications at least two months prior to the start of construction.

State-Level HVAC and Building Code Framework in South Dakota
South Dakota utilizes a decentralized approach to building codes, meaning there is no single, uniform building code enforced statewide by a central agency. Instead, the adoption and enforcement of building codes, including those for HVAC systems, are largely handled at the local municipal or county level. When local jurisdictions choose to adopt building ordinances, they are generally guided by the International Code Council (ICC) standards, such as the International Mechanical Code (IMC) and the International Fuel Gas Code (IFGC).
Regulatory Oversight and Licensing
While building code enforcement is decentralized, specific aspects of HVAC and mechanical work are regulated through state-level licensing and safety programs:
- South Dakota Plumbing Commission: This commission oversees the licensing of contractors and professionals involved in mechanical and plumbing work, including appliance installation. It ensures that practitioners meet examination and continuing education requirements.
- South Dakota Department of Public Safety (State Fire Marshal): The State Fire Marshal's Office is responsible for fire safety standards and the inspection of specific equipment, such as boilers, under South Dakota Codified Law (SDCL) 34-29A.
- South Dakota Electrical Commission: This body oversees electrical standards, which are critical for the operation of HVAC systems, and enforces the National Electrical Code (NEC) across the state.
