Do you need a building permit in Spink County, South Dakota?
Yes. Spink County requires a building permit for a new structure or an improvement when its market value, including labor and materials, exceeds $2,5001. A moved structure needs a permit regardless of moving cost, and any structure requiring additional land or area for siting also needs one1. Mobile homes brought into Spink County require a permit; units more than 15 years old require a variance supported by interior and exterior photographs1. The Zoning Administrator may inspect buildings, structures and land uses to check compliance, though the reviewed ordinance sets no universal inspection schedule9. The ordinance does not establish a general owner-builder exemption from the county permit requirement, so an owner doing the work should still start with Planning and Zoning5. South Dakota separately excludes farmsteads and their accessory buildings from the state's default 2024 International Building Code design standard for work commenced after July 1, 2026, but that exclusion does not waive Spink County permits or zoning10.
Who issues building permits in Spink County, and how do you reach them?
Spink County Planning and Zoning is the first stop for building permits and zoning questions5. The office is at 210 E 7th Avenue, Suite 7, Redfield SD 57469-1299; call (605) 472-4585 or email ericka.dale@spink.sdcounty.gov5. The county says the office monitors building permits, keeps setbacks consistent, and handles variances, plats, and rezoning5. Building-permit applications must show the lot dimensions, existing buildings, the proposed building or alteration, intended uses, dwelling or rental-unit count, and enough site information to check ordinance compliance11. The County Commissioners set fees for building permits, certificates of zoning compliance, appeals, and other zoning matters, and the county takes no action until applicable charges are paid12. The county's 2026 non-mandated fee schedule lists a $30.00 building permit for projects valued at $0 to $50,000 and $60.00 for $50,001 to $150,000, with a one-time renewal fee of 50% of the original fee13. Ask Planning and Zoning for the current fee and what construction documents or closeout approvals apply to the specific project5.
Does Spink County have zoning?
Yes, but who administers zoning varies by location. Spink County's ordinance covers unincorporated county land and the listed communities of Ashton, Brentford, Conde, Doland, Frankfort, Hitchcock, Mellette, Northville, Tulare, Turton, Athol, and Mansfield, but it excludes land inside Redfield city limits; inclusion in that list does not by itself mean the county administers every municipal ordinance2. The official zoning map determines the parcel's district, and district-specific rules control uses, lot standards, and setbacks14. In the Agricultural District, the minimum lot is 1 acre with 150 feet of width, while the Rural Urban District allows 7,200 square feet for a single- or two-family dwelling715. Agricultural District structures generally must sit at least 75 feet from an improved public-road right-of-way and at least 20 feet from side and rear lot lines16. Lake Front Residential standards differ, so do not apply the agricultural numbers to a lake lot16. Planning and Zoning should confirm both the responsible jurisdiction and the standards for the parcel5.
Who issues septic permits in Spink County, South Dakota?
On-site wastewater systems in Spink County are governed by South Dakota DANR requirements, with local Planning and Zoning handling site-level permitting3. DANR publishes installation requirements and a checklist for submitting septic-tank installation plans; the on-site wastewater program can be reached at (605) 773-464717. South Dakota's rules direct that DANR be contacted before any new on-site system other than a conventional system serving an individual residence, and installers must be certified by the South Dakota Plumbing Commission18. State requirements are minimums, and a local government may impose more stringent standards19. Only 18.9% of Spink County soils are rated without severe limitations for a conventional septic drain field, so septic feasibility deserves attention before choosing the house site20. South Dakota allows a vault privy, chemical toilet, incinerator toilet, or composting unit where water or electrical service is unavailable, but every listed option except a vault privy is treated as experimental and needs plans and specifications approved before installation21. A general county septic-inspection schedule was not confirmed, so ask Planning and Zoning and DANR what reviews apply to the proposed system517.
Can you live in an RV or tiny home on land in Spink County?
Spink County's reviewed ordinance does not provide a confirmed countywide answer for living in an RV or occupying a tiny home, so ask Planning and Zoning about the parcel's district and the exact proposed use before placing either one5. The same caution applies to temporary camping and accessory dwellings because the available rules do not establish one result for every parcel5. Mobile homes have clearer rules: the Agricultural District permits single- or two-family dwellings including mobile homes, and the Lake Front Residential District permits them but excludes mobile home parks22. Every mobile home brought into Spink County needs a building permit, and one more than 15 years old needs a variance with interior and exterior photographs1. Zoning coverage also changes at Redfield's boundary because the county ordinance excludes Redfield city limits while covering unincorporated land and several named communities23. For an off-grid sanitation plan, state rules allow specified unconventional systems only under stated conditions, and most require state approval before installation21.
How do you build a home in Spink County, step by step?
Call Spink County Planning and Zoning at (605) 472-4585 to confirm jurisdiction, the zoning district, allowed use, setbacks, and the applications your project needs5.
Prepare the building-permit application with parcel dimensions, existing improvements, the proposed building or alteration, uses, and other site details required for ordinance review11. Ask for the current fee schedule and pay the applicable charges so review can begin12.
Confirm the wastewater design with local Planning and Zoning and South Dakota DANR before installation317.
If the water use requires a state water-right permit, obtain approval before drilling and use a licensed well driller8.
Arrange separate electrical and plumbing approvals; qualifying owner-occupants may perform their own wiring with an approved homeowner permit, but the exemption is from licensure rather than inspection6.
Contact the Spink County Highway Superintendent before adding or removing an approach on a county road, and obtain a South Dakota DOT permit before constructing access to a state highway2425.
What should you check before buying land in Spink County?
Start with the zoning map, legal access, buildable setbacks, and wastewater feasibility rather than assuming a large rural tract is ready to build1416. County-road approaches must be at least 500 feet apart, with each side treated separately, and the Highway Superintendent must be contacted before an approach is placed or removed24. The Spink County Highway Department is at 1518 E 7th Avenue, Redfield SD 57469 and can be reached at (605) 472-500826. Spink County is very rural, with 6,166 residents and a density of 4.1 people per square mile2728. The county receives about 22.1 inches of precipitation annually, while 99.4% of its land has a slope of 15% or less2930. The effective property-tax rate is about 1.3%, and the median annual property-tax bill is $1,5393132. Development in a mapped special flood-hazard area faces additional county standards, including limits on floodway encroachments33.
Watch-outs
A project below the $2,500 permit threshold may still have to meet district setbacks, so contact Spink County Planning and Zoning before starting15.
Every mobile home brought into Spink County requires a permit, and a unit more than 15 years old requires a variance with photographs1.
Only 18.9% of Spink County soils are rated without severe limits for a conventional septic drain field20.
Spink County's reviewed materials do not confirm a general rule for RV living, tiny-home occupancy, or minimum dwelling size; ask Planning and Zoning about the specific parcel and use5.

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:”
