Do you need a building permit in Clark County, South Dakota?
Yes. Clark County requires a permit before a building is erected, enlarged, or structurally altered1. Clark County maintains its own zoning ordinance and map, while incorporated municipalities may apply separate rules2. Ask Planning & Zoning which application and current district standards apply before ordering plans or beginning site work4. South Dakota does not allow local governments to require a building permit for substantially similar repair or replacement of specified exterior parts of a detached, owner-occupied single-family home, but other codes and ordinances still apply9. The statewide residential energy-efficiency standard is the voluntary 2009 International Energy Conservation Code; we could not confirm that Clark County has adopted a separate building code10. Ask Planning & Zoning about fees, inspections, and occupancy approval4.
Who is the Clark County zoning office, and how do you reach them?
Start with Clark County Planning & Zoning on the second floor of the courthouse at 605-532-37514. The county page links the zoning ordinance, official map, and amendment materials4. For questions about access from a county road, contact the Clark County Highway Superintendent at the courthouse, PO Box 294, Clark, SD, at 605-532-366711. South Dakota DANR administers the statewide on-site wastewater standards; its listed program contact is at 523 E Capitol Ave, Pierre, SD 57501-3182, at (605) 773-4647125. These are separate approvals: a county building permit or zoning approval does not replace state electrical, plumbing, septic, water-right, or state-highway requirements13141516.
Does Clark County have zoning?
Yes. Clark County maintains a county zoning ordinance and official zoning map, while municipalities may apply their own rules inside incorporated boundaries2. The official map identifies Commercial/Industrial, Town, two aquifer-protection zones, and municipalities, and it replaces the map adopted with the original county ordinance3. The map is only a starting point because district regulations remain subject to the ordinance and later amendments17. We could not confirm the current minimum lot size, setbacks, lot coverage, building height, or minimum dwelling size. Give Planning & Zoning the parcel number and proposed use, then ask for the current ordinance section and every amendment that applies4.
How do septic permits work in Clark County?
South Dakota sets the minimum requirements for on-site wastewater systems in Clark County, and local governments may impose stricter requirements5. A conventional individual on-site system may be designed and installed under the state rules without submitting project plans to DANR, while other systems receiving human waste require state review and approval before construction7. A certified installer is required, and a public sewer can rule out a private system when the state availability conditions are met7. Ask Planning & Zoning whether the parcel has an additional local land-use or aquifer-overlay condition4. Only 6.3% of Clark County soils are rated without severe limitations for a conventional drain field, so test the site early18. We could not confirm a general county inspection process; ask DANR what review applies before hiring or excavating12.
Can you live in an RV or tiny home on your land in Clark County?
We could not confirm whether Clark County allows full-time RV occupancy, temporary camping during construction, or a tiny home as a permanent dwelling. Do not treat that gap as permission. Ask Clark County Planning & Zoning about the exact parcel, mapped district, proposed duration, utility connections, and whether the unit will be on wheels or a permanent foundation194. Manufactured-home occupancy, accessory dwellings, and minimum dwelling size also remain unconfirmed. South Dakota's sanitation rule answers only waste disposal where water or electricity is unavailable: listed alternatives are limited, and every listed option except a vault privy requires advance approval as an experimental system20. That sanitation rule does not authorize residential occupancy. Get the county's written land-use answer before buying an RV or tiny home for the site, and separately confirm sanitation requirements with DANR412.
Building a home in Clark County: the steps, in order
Ask Clark County Planning & Zoning to confirm the parcel's mapped district, permitted use, current setbacks, and application requirements34.
Apply for the required county building permit before construction1.
Test septic feasibility early and ask DANR whether state plan review is required; only 6.3% of county soils are rated without severe conventional-drain-field limitations718.
Determine whether the proposed well use needs a water-right permit; when one is required, approval must precede drilling15.
Secure state electrical and plumbing paperwork and inspections. Qualifying owners may perform wiring under the owner exemption, but must obtain the homeowner permit and pass final inspection before occupancy212214.
Contact the Highway Superintendent about county-road access, or obtain South Dakota DOT permission before building an approach to a state highway1116.
What to check before you buy land in Clark County
Check the county zoning map and obtain the current district standards before treating acreage as buildable34. Investigate septic feasibility early because only 6.3% of county soils are rated without severe limitations for a conventional drain field18. Clark County is mostly gentle ground, with 98.7% of land at a slope of 15% or less, but just 1.7% is wooded, so a parcel may offer little natural wind cover2324. Annual precipitation is about 24.1 inches, and severe drought occurs in about 2.7% of years2526. Verify legal road access and ask the Highway Superintendent about a county-road approach; a connection to a state highway needs South Dakota DOT permission before construction1116. If a well is planned, determine whether the proposed use needs a water-right permit before drilling15. The effective property-tax rate is about 1%, and the median annual bill is about $1,3922728.
Watch-outs
Clark County's current permit fees, local building-code adoption, inspection sequence, and certificate-of-occupancy process were not confirmed; ask Planning & Zoning before budgeting or scheduling work4.
RV, temporary-camping, tiny-home, manufactured-home, and accessory-dwelling occupancy rules remain unconfirmed; get a parcel-specific answer from Planning & Zoning4.
Only 6.3% of Clark County's soils are free of severe limitations for a conventional septic drain field; get a site evaluation before you make an offer on land that depends on a standard system18.

Building code adoptedPartial
South Dakota building-code adoption framework for local governments, including residential structures and county or municipal construction standards.
For residential structures, the statute authorizes the governing body of a municipality to adopt the 2024 International Residential Code; the quoted residential authorization does not name counties.
A residential-structure rule may not require installation of a sprinkler system and may not impose requirements more stringent than the 2024 International Residential Code.
A residential structure means a detached one-family or two-family dwelling, a townhouse not more than three stories with a separate means of egress, and related accessory structures.
For buildings other than residential structures, a local-unit ordinance must comply with the 2024 International Building Code, subject to statutory exclusions and permitted amendments.
The nonresidential rule does not apply to HUD-compliant mobile or manufactured homes, may not require fire sprinklers in a single-family dwelling, and does not apply to qualifying specialty resorts or vacation-home establishments constructed to Group R-3 requirements.
Where a local unit has not adopted a qualifying ordinance, the default 2024 International Building Code design standard applies to covered construction commenced after July 1, 2026, but the default does not apply to residential structures, mobile or manufactured homes, farmsteads, or accessory structures.
residential model code: 2024 International Residential Code (Municipal governing body authorization; no sprinkler requirement; no requirements more stringent than the code) · nonresidential model code: 2024 International Building Code (Statutory exclusions apply) · default nonresidential design-standard commencement: > 2026-07-01 (The default does not apply to residential structures, mobile or manufactured homes, farmsteads, or accessory structures)
“The governing body of a municipality may enact requirements for construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal, and demolition of a residential structure by adopting the 2024 edition of the International Residential Code, as published by the International Code Council, Incorporated.”

The default standard applies to building work commenced after July 1, 2026.
The local unit of government may adopt an ordinance allowing local administration and enforcement of the design standard.
The exclusion is from SDCL 11-10-6's default 2024 International Building Code design standard; it does not establish that all local zoning, building, occupancy, or other requirements are waived.
The statute defines farmstead as a farm or ranch, including any structure or building located on the land.
Residential structures and mobile or manufactured homes are also excluded from this specific default-standard provision.
construction commencement date: > 2026-07-01 (The provision applies to buildings commenced after July 1, 2026.) · building standard: 2024 International Building Code (The default standard does not apply to a farmstead or accessory structure or building thereto.)

county zoning authorityGeneral
South Dakota county boards' authority to adopt zoning ordinances, including for unincorporated county land.
The authority is granted for promoting the health, safety, or general welfare of the county.
The statute authorizes regulation of building and land-use characteristics including height, number of stories, building and structure size, lot coverage, yards, courts, open spaces, population density, and locations and uses of buildings, structures, and land.
The authorized purposes expressly include trade, industry, residence, flood plain, and other purposes.
This claim identifies statewide enabling authority; whether a particular county has adopted an ordinance is a separate local question.
“For the purpose of promoting health, safety, or the general welfare of the county the board may adopt a zoning ordinance to regulate and restrict the height, number of stories, and size of buildings and other structures, the percentage of lot that may be occupied, the size of the yards, courts, and other open spaces, the density of population, and the location and use of buildings, structures, and land for trade, industry, residence, flood plain, or other purposes.”
county building authorityLimited
County authority to prescribe building standards and issue building permits for construction in South Dakota, including unincorporated areas.
Section 11-10-5 expressly addresses ordinances adopted by any local unit of government, and expressly provides for amendments to a county ordinance filed with the county auditor.
That provision concerns buildings other than residential structures as defined in § 11-10-12.
Section 11-10-12 expressly authorizes a municipality to enact residential-structure requirements using the 2024 International Residential Code, rather than expressly extending that authorization to counties.
A county, municipality, or township may not require permits for specified repairs or substantially similar replacements to existing exterior parts of a detached single-family owner-occupied residential structure, except designated historical property repairs authorized under chapter 1-19B.
Construction under the default § 11-10-6 standard is subject to the residential, manufactured-home, farmstead, accessory-structure, and specialty-resort exclusions stated there.
nonresidential code: 2024 International Building Code (County ordinances may amend, modify, or delete portions before enactment; HUD-compliant mobile or manufactured homes and specified Group R-3 specialty resorts or vacation home establishments are excluded; no single-family dwelling fire sprinkler may be required.) · permit exemption effective date: 2026 (Applies to listed repairs and substantially similar replacements of existing exterior parts.)
“Additional deletions, modifications, and amendments to the county ordinance may be made by the governing body and are effective upon their adoption and filing with the county auditor. [...] Notwithstanding any authority granted to a county, municipality, or township to prescribe building codes or standards or to issue building permits, a county, municipality, or township may not require a building permit for the repair or substantially similar replacement of any of the following existing exterior parts of a detached single-family owner-occupied residential structure:”
