South Dakota Statewide Rule

South Dakota state law: detached sheds and accessory storage structures

Few RestrictionsApplies statewide across South Dakota (2026)

South Dakota has no statewide shed permit, size limit, or setback rule. SDCL Chapter 11-4 (municipal zoning) and SDCL Chapter 11-2 (county zoning) delegate shed regulation entirely to local governments. Most South Dakota jurisdictions adopt the International Residential Code (IRC), which exempts detached one-story tool/storage sheds under 200 sq ft from the building-permit requirement under IRC Section R105.2 — but ZONING setback and height rules still apply.

Full Breakdown

South Dakota is a Dillon's-Rule state under Article IX § 2 of the South Dakota Constitution; statutory cities operate under powers expressly granted in SDCL Title 9, and only Sioux Falls, Rapid City, and Watertown have adopted home-rule charters under SDCL Chapter 6-12. The state has not enacted a uniform building code — each county and municipality adopts its own version of the International Residential Code (IRC). Under IRC Section R105.2 (as commonly adopted in South Dakota), 'one-story detached accessory structures used as tool and storage sheds, playhouses and similar uses, provided the floor area does not exceed 200 square feet (18.58 m²)' are exempt from the building-permit requirement. This building-permit exemption is NOT a zoning exemption: sheds still must comply with the local zoning code's setback (typically 3–10 ft from rear/side property lines), maximum height (typically 12–15 ft), and prohibitions on front-yard accessory structures. Sheds over 200 sq ft, sheds with electrical service, sheds with plumbing, sheds on permanent foundations, and any shed proposed within a FEMA Special Flood Hazard Area require a building permit and floodplain-development permit. SDCL Chapter 11-4 grants municipal zoning authority; SDCL Chapter 11-2 grants the parallel county zoning authority over unincorporated areas. Home-rule cities (Sioux Falls Title 153, Rapid City zoning code, Watertown code) impose their own shed standards under SDCL 6-12 charter authority.

Violations & Penalties

Violations of local shed/accessory-structure ordinances are typically zoning code violations enforced civilly: stop-work orders, notice of violation, requirement to remove or relocate the shed to comply with setback, and daily fines accruing until compliance. Constructing a permit-required shed (over 200 sq ft, with utilities, or in a floodplain) without a permit may require demolition or after-the-fact permit with double fees. SDCL 9-32 provides municipal nuisance-abatement authority where a shed becomes dilapidated or unsafe.

Frequently Asked Questions

Does South Dakota require a state permit to build a backyard shed?

No. South Dakota does not issue accessory-structure permits at the state level. Permitting is delegated to the local city or county building department under SDCL Chapter 11-4 (municipal zoning) or SDCL Chapter 11-2 (county zoning). Most jurisdictions follow IRC Section R105.2 and exempt detached storage sheds under 200 sq ft from the building-permit requirement, though zoning setbacks still apply.

Is there a statewide shed size or setback rule in South Dakota?

No. The state codified laws contain no uniform residential shed size, height, or setback standard. Every shed standard you must comply with comes from the local zoning code adopted by your city (statutory or home-rule) or county. Typical local rules limit sheds to 3–10 ft from rear/side lot lines, prohibit front-yard sheds, and cap height around 12–15 ft.

When is a building permit required for a shed in South Dakota?

Under the IRC adopted by most South Dakota jurisdictions, a permit is required when the shed exceeds 200 sq ft of floor area, includes electrical or plumbing, has a permanent foundation, is sited in a FEMA Special Flood Hazard Area, or when local zoning otherwise requires a zoning permit. Confirm with your local building department before building.
