Bill Overview

Analyzed Economic Effects

3 provisions identified: 0 benefits, 0 costs, 3 mixed.

Default building standards where local rules lack

Covered construction starting after July 1, 2026, must use the 2024 International Building Code as its design base. This applies in South Dakota areas without a local construction ordinance under the law. Local governments can adopt ordinances to administer and enforce these standards. Residential structures, mobile or manufactured homes, farmsteads, and farmstead accessory structures are excluded. Mobile or manufactured homes used for nonresidential purposes are exempt when they meet applicable federal housing and accessibility standards. Specialty resorts and vacation home establishments are also exempt when built to the 2024 code's Group R-3 requirements.

Updated local building rules with homeowner protections

South Dakota local governments that adopt nonresidential building rules must base them on the 2024 International Building Code. They can change or remove parts of the code, but cannot require sprinklers in single-family homes. These ordinances exclude mobile or manufactured homes built to federal housing standards that applied when built. They also exclude specialty resorts and vacation home establishments built to the 2024 code's Group R-3 requirements. Municipalities can adopt the 2024 International Residential Code for homes and amend its rules. They cannot require residential sprinklers or impose rules stricter than that code. Covered homes include detached one-family and two-family homes, plus townhouses no taller than three stories with separate exits. Their accessory structures are also covered. Nonresidential ordinance changes take effect upon adoption and filing with the municipal finance officer or, for counties, the county auditor.

Updated upkeep rules for property owners

South Dakota local governments that adopt upkeep rules for existing buildings and premises must use the 2024 International Property Maintenance Code. They can change or remove parts of the code. Ordinance changes take effect upon adoption and filing with the municipal finance officer or, for counties, the county auditor. Local rules cannot conflict with federal housing standards that applied to manufactured homes when they were built.
