Do you need a building permit in South Dakota?

Usually yes, but not from South Dakota itself: permits are issued by the city or county, not the state, so the rule that governs your project is the one your own jurisdiction publishes. 7 of those local rules require a permit outright, 5 depend on a size or scope condition the office publishes, and 0 need none. South Dakota sets the building code those local rules derive from; your city or county sets the threshold and the fee.

Building without a permit in South Dakota

South Dakota has no single statewide crime for building without a building permit; building permits are issued and enforced by cities and counties under their own ordinances (9-33-6, 11-10-5, 11-10-12). State law caps those local penalties: a city may seek an injunction and set penalties for an ordinance violation no greater than a Class 2 misdemeanor (9-19-3), and a county may punish each ordinance violation by a fine up to the Class 2 limit, up to 30 days in jail, or both, or sue for an injunction (7-18A-2).

What each South Dakota jurisdiction publishes

One line per jurisdiction, written from its own rules rather than from a state summary. This is the section that used to be a list of links, and the states with the fewest jurisdictions to compare are the ones it says the most about.
