Here's how to check. South Dakota has **no mandatory statewide residential building code**. Whether the IRC applies to your project — and which edition — depends entirely on whether your city or county has adopted one, and if so, when and with what amendments. There’s no single figure set to point to here. Where a local jurisdiction has adopted the IRC, a house stair typically follows the standard figures — 7¾ in max riser, 10 in min tread, 6 ft 8 in headroom, 36 in min width, 34–38 in handrails, 36 in guards, the 30 in guard trigger and the 4 in sphere — see the [US stair & guard rules](https://www.chippy.tools/building-codes/us/stairs/stair-and-barrier-requirements/). But treat those as a starting point only: **check with your city or county building department** for the edition and amendments actually in force before you build. ## Adoption status Local Current code in force local adoption — no statewide residential (IRC) code Next edition — Adoption / transition local adoption; state has no mandatory statewide one/two-family dwelling code (edition varies by jurisdiction) Last verified 2026-07-28 No state-specific variations recorded yet for this jurisdiction. This page is general information for tradespeople and is not compliance, engineering or legal advice. Requirements are subject to state and territory variations and adoption timing. Always confirm requirements with your building certifier and relevant state authority. ## Page directory ## Other languages - [es](https://www.chippy.tools/es/building-codes/us/sd/index.md)
