Do you need a building permit in Hanson County, South Dakota?
Yes. Unincorporated Hanson County requires a zoning permit before erecting, moving, adding to or changing the use of a building or other structure.1 The permit must conform to the zoning ordinance unless the applicant has a written Board of Adjustment order for administrative review, a conditional use or a variance.1
The reviewed county ordinance establishes zoning approval but does not identify an International Building Code edition or say that Hanson County adopted it as a building-code ordinance.1 For certain nonresidential work begun after July 1, 2026, South Dakota defaults to a standard based on the 2024 International Building Code where a local government has not adopted its own standards; residences, manufactured homes and farmsteads are excluded, and we could not confirm whether that default applies in Hanson County.14 Ask the Zoning Administrator about code and inspection requirements.15
Who handles Hanson County building permits and zoning?
The Hanson County Zoning Administrator is the first call for the county zoning permit at 605-239-4445.15 The application requires the owner of record's signature or written approval and a site plan showing the parcel and proposed work.2
A project that does not meet the ordinance may require Board of Adjustment review, conditional-use approval or a variance.1 The permit expires if work has not begun within 180 days or has not been substantially completed within 2 years.1 The ordinance also requires a zoning-compliance application after completion or substantial completion, and fees must be paid before the county acts.2 Fee amounts, construction inspections and any certificate-of-occupancy requirement remain unconfirmed; ask the Zoning Administrator about costs and the full sequence before ordering materials.15
Does Hanson County have zoning?
Yes. Hanson County zoning applies throughout unincorporated territory but not inside Alexandria, Emery or Fulton.8 The official map includes Agricultural, Residential, Rural Commercial, Industrial, Floodplain, Planned Unit Development and Manufactured Home Park districts.3 Agricultural single-family lots generally require at least 10 acres, while Residential lots for single- or two-family dwellings require at least 1 acre and 100 feet of width; stated exceptions may apply.4
Agricultural yards generally require 75 feet in front and 50 feet at the rear and sides, while Residential yards require 30 feet in front, 25 feet at the rear and 7 feet at the sides.5 Agricultural coverage is capped at 10 percent and Residential coverage at 40 percent.6 Residential buildings generally may not exceed 35 feet, while Rural Commercial and Industrial structures generally may not exceed 75 feet.7 Confirm the mapped district before laying out a homesite.15
How do septic permits work in Hanson County?
South Dakota's Department of Agriculture and Natural Resources sets the statewide minimum requirements for on-site wastewater systems, and local governments may impose stricter rules.9 DANR lists (605) 773-4647 for questions.16 Contact DANR before installing a new system unless it is a conventional system serving an individual residence; other covered systems require plans and specifications, and works of sanitary significance require submission at least 30 days before construction.10
Only 9.8% of Hanson County's mapped soils are rated without severe limitations for a conventional septic drain field.17 Evaluate the actual homesite before fixing the house location or closing on land. We could not confirm a Hanson County septic-inspection rule. Unconventional sanitation may be used where water or electricity is unavailable, but systems other than vault privies are experimental and require state approval before installation.18
Can you live in an RV or tiny home on your land in Hanson County?
We could not confirm a Hanson County rule that specifically resolves long-term RV occupancy on private unincorporated land. Campground rules do not answer that question: an approved campground must use the conditional-use process and provide sanitary and water stations, toilets and refuse containers.1920 Ask the Zoning Administrator how the parcel's district treats one RV used as housing.15
Manufactured homes are allowed in Residential districts when they meet the ordinance's performance and district standards.11 Outside an approved manufactured-home park, occupancy of a parked manufactured home is limited to 48 hours without a special permit; construction-related occupancy on land owned by the occupants may be permitted for up to 180 days and renewed once for up to another 180 days.21 We could not confirm a rule specific to tiny homes or a minimum dwelling floor area, so ask how the proposed unit will be classified before buying it.15
Building a home in Hanson County: the steps, in order
Call the Hanson County Zoning Administrator at 605-239-4445 to identify the parcel's district, allowed use and any need for Board of Adjustment action.153
Lay out the home using the district's lot-size, setback, coverage and height limits.4567
Prepare the site plan, obtain owner approval and apply before construction or a change of use.21
Evaluate the septic site and contact DANR when the proposal requires state review.1016
Check the flood map and obtain a county development permit before work in a special flood hazard area.13
Arrange applicable state electrical and plumbing permits, certificates and inspections.2223
Determine whether a state water-right permit is required before drilling a well, and obtain state permission for access to a state highway.2425
What should you check before buying land in Hanson County?
Confirm the zoning district before treating acreage as buildable. Agricultural home sites generally need 10 acres, Residential home sites need at least 1 acre and 100 feet of width, and district setbacks can consume a substantial part of a parcel.45 Land under 10 acres generally cannot be subdivided, transferred or recorded as separate parcels without a plat, subject to the ordinance's exemptions.26
Check septic feasibility, flood exposure, legal access and water before closing. Only 9.8% of mapped soils avoid severe limitations for a conventional drain field, and development in a special flood hazard area needs a county permit.1713 A state water-right permit may be required before well drilling, and access onto a state highway requires state permission before construction.2425 Farmland value averages about $5,155 per acre, while the median property-tax bill is about $1,973 per year; an individual parcel may differ.2728
Watch-outs
A Hanson County zoning permit is required for a building or structure's erection, movement, addition or change of use; do not treat the lack of a confirmed inspection program as a permit exemption.1
A tract under 10 acres generally must be platted before it is subdivided, transferred or recorded as separate land, subject to the ordinance's exemptions.26
A manufactured home parked outside an approved park generally may not be occupied beyond 48 hours without a special permit; construction housing has a separate temporary-permit path.21

The chief engineer may permit construction of a test well before obtaining the water-right permit; the test well may serve as the production well if the application is approved.
A water-right permit, when required and approved, provides five years to construct the water-use system and an additional four years to place all water to beneficial use.
A well driller's license is required before drilling any well or contracting to drill a well.
construction period after water-right permit approval: 5 years · period to place water to beneficial use: 4 years

Agricultural exemptionAvailable (with conditions)
Farmsteads and accessory structures or buildings thereto under South Dakota's default construction-design standard when the local unit of government has not adopted an ordinance prescribing standards under SDCL 11-10-5.
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.)

“A wiring permit may be obtained for twenty dollars from the commission office. A wiring permit is valid for three years from the date the permit is issued.”
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.
