Building permits, zoning and land rules 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 schedule¹. 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 Zoning⁴. 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 zoning⁷.

Spink County Planning and Zoning is the first stop for building permits and zoning questions⁴. The office is at 210 E 7th Avenue, Suite 7, Redfield SD 57469-1299; call (605) 472-4585 or email ericka.dale@spink.sdcounty.gov⁴. The county says the office monitors building permits, keeps setbacks consistent, and handles variances, plats, and rezoning⁴. 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 compliance⁸. 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 paid¹. 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 fee⁹. Ask Planning and Zoning for the current fee and what construction documents or closeout approvals apply to the specific project⁴.

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 ordinance¹. The official zoning map determines the parcel's district, and district-specific rules control uses, lot standards, and setbacks¹. 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 dwelling¹. 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 lines¹. Lake Front Residential standards differ, so do not apply the agricultural numbers to a lake lot¹. Planning and Zoning should confirm both the responsible jurisdiction and the standards for the parcel⁴.

On-site wastewater systems in Spink County are governed by South Dakota DANR requirements, with local Planning and Zoning handling site-level permitting². DANR publishes installation requirements and a checklist for submitting septic-tank installation plans; the on-site wastewater program can be reached at (605) 773-4647². 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 Commission³. State requirements are minimums, and a local government may impose more stringent standards³. 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 site¹⁰. 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 installation¹¹. A general county septic-inspection schedule was not confirmed, so ask Planning and Zoning and DANR what reviews apply to the proposed system^2,4.

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 one⁴. The same caution applies to temporary camping and accessory dwellings because the available rules do not establish one result for every parcel⁴. 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 parks¹. 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 communities¹. For an off-grid sanitation plan, state rules allow specified unconventional systems only under stated conditions, and most require state approval before installation¹¹.

1. Call Spink County Planning and Zoning at (605) 472-4585 to confirm jurisdiction, the zoning district, allowed use, setbacks, and the applications your project needs⁴.

1. Prepare the building-permit application with parcel dimensions, existing improvements, the proposed building or alteration, uses, and other site details required for ordinance review⁸. Ask for the current fee schedule and pay the applicable charges so review can begin¹.

1. Confirm the wastewater design with local Planning and Zoning and South Dakota DANR before installation².

1. If the water use requires a state water-right permit, obtain approval before drilling and use a licensed well driller⁶.

1. 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 inspection⁵.

1. 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 highway^1,12.

Start with the zoning map, legal access, buildable setbacks, and wastewater feasibility rather than assuming a large rural tract is ready to build¹. 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 removed¹. The Spink County Highway Department is at 1518 E 7th Avenue, Redfield SD 57469 and can be reached at (605) 472-5008¹³. Spink County is very rural, with 6,166 residents and a density of 4.1 people per square mile¹⁰. The county receives about 22.1 inches of precipitation annually, while 99.4% of its land has a slope of 15% or less¹⁰. The effective property-tax rate is about 1.3%, and the median annual property-tax bill is $1,539¹⁰. Development in a mapped special flood-hazard area faces additional county standards, including limits on floodway encroachments¹.
