Who the section binds

Read the first clause again. The prohibition runs against “a county, municipality, or township.” It is a limit on governmental permitting power, and it says nothing at all about private covenants.

An owner in a South Dakota subdivision replacing siding still owes the architectural review committee whatever the declaration requires. Fencing panels and posts, windows, doors, gutters and soffits are exactly the items a design covenant regulates by colour, material and style — and every one of them is on this list.

The predictable failure mode is an owner who reads a headline about permit-free repairs, replaces siding in a colour the declaration does not allow, and is genuinely surprised. The two systems were never the same system. Our architectural review and fences and exteriors pages cover the covenant side.

The scope exclusion most readers will miss

The section reaches a “detached single-family owner-occupied residential structure.” Three qualifiers, and each one excludes a common association property type.

Detached leaves out attached townhomes, rowhouses and any shared-wall unit. Single-family leaves out duplexes through fourplexes and any multi-family building. Owner-occupied leaves out rentals, including an investor-owned unit inside an otherwise owner-occupied subdivision.

A condominium unit is outside the section entirely. So is a townhome in a townhome association — which is a large share of the association-governed housing in Sioux Falls and Rapid City.

And in most condominium and townhome regimes the exterior components on this list are common elements maintained by the association rather than the unit owner, so the question of who pulls a permit does not arise for an owner at all.

The related change that does reach townhomes

SB 129 of the same session moved South Dakota's statutory building-code references from the 2021 to the 2024 editions of the International Building Code, International Property Maintenance Code and International Residential Code, amending SDCL 11-10-5, 11-10-6, 11-10-11 and 11-10-12. Senate 34-0, House 64-3, signed March 4, 2026, effective July 1, 2026.

SDCL 11-10-12 as amended defines the residential structures it covers: “a detached one-family or two-family dwelling, and townhouses not more than three stories in height, with a separate means of egress and any accessory structure of the dwelling or townhouse.”

Townhouses up to three stories are expressly inside the IRC definition. So a townhome association's maintenance specifications, reserve study component list and contractor scopes that cite the 2021 editions are now citing a superseded reference wherever a local jurisdiction has adopted the state baseline.

SB 129 also has a history worth noting: the identical bill failed in 2025 as SB 98, deferred to the 41st legislative day by Senate Commerce and Energy 5-4 on February 6, 2025, and returned a year later to pass 34-0.

What actually changes on the ground

For a detached-home subdivision: the association's approval process becomes the only review for these eight items. Where a board previously learned of a siding replacement because the city posted a permit, it now learns when it sees the siding.

For a townhome or condominium association: nothing changes on permits, and the code baseline underneath the building moved.

For historic districts: permits can still be required, which matters in Deadwood and in the historic districts of Sioux Falls and Yankton — and that overlaps with the 2025 seller-disclosure change discussed on our estoppel and resale page.

What to watch next

Whether local jurisdictions adopt the 2024 code editions promptly, since the state reference only matters where a jurisdiction has taken it up, and whether the permit exemption is extended in a future session to attached dwellings — the detached-only limit is the kind of line that generates a follow-up bill.
