Do you need a building permit in Butte County, South Dakota?
Yes, outside the city limits of Belle Fourche, Newell and Nisland: the county's building permit application is required for property located there1. The fee is $50 per structure, payment is due when you apply (cash or check only), and work must start within 180 days and finish within 2 years1. The completed application, documentation, plans and fees are due at submission, and the checklist includes a 911 address application, proof of the sewer permit and septic design, a site plan and plans or blueprints9. A new driveway needs an approval letter for the approach, and property in a floodplain also needs a floodplain development permit1011. We could not confirm whether the county performs building inspections or issues certificates of occupancy, so ask Butte County Planning12. State electrical and plumbing requirements remain separate from the county permit1314.
Who issues building permits in Butte County, and how do you reach them?
Butte County Planning is the first stop for building permit and septic permit questions outside city limits12. The office is at 117 5th Ave, Belle Fourche, SD 57717, phone (605) 892-3950, and the county Planning Board meets monthly at the courthouse12. Bring the legal description, a site plan and your septic design, since the application checklist asks for them9. If the parcel is inside Belle Fourche, Newell or Nisland, contact that city for building permits instead, because the county form applies only outside their limits; septic permits still come from the county115. We could not locate those cities' own zoning rules.
Does Butte County, South Dakota have zoning?
No. A county source states plainly that Butte County does not have zoning or code enforcement2. Because of that, the county sets no zoning districts, minimum lot size, minimum dwelling size, setbacks, lot coverage or building height for unincorporated land1645171819. That absence covers county zoning only: the building permit, septic, driveway and floodplain rules above still apply, and the county permit form still asks for project distances from property lines17. South Dakota law lets a county board adopt a zoning ordinance, so confirm with Butte County Planning that nothing has changed before you buy2012. Inside Belle Fourche, Newell and Nisland, city rules may differ and we could not confirm them.
How do septic permits work in Butte County?
Butte County issues the septic permit, and the permit application names Butte County Planning as the payee15. A septic permit is required to install or modify any wastewater system in the county3. Obtain a 911 address before installation and use a South Dakota-licensed installer3. A single disposal system on a single parcel of 40 acres or more need not be designed by an engineer, but the rest of the county's Wastewater Disposal Permit Ordinance still applies3. Only about 9.2% of mapped soils lack severe limitations for a conventional drain field, so plan for a site evaluation and possibly an engineered system on smaller parcels21. The building permit checklist asks for proof of the sewer permit, so apply for septic first9.
Can you live in an RV or tiny home on land in Butte County?
Butte County has no county zoning, so no county zoning district restricts an RV or tiny home on unincorporated land2. We could not confirm a separate county rule on long-term RV occupancy, temporary camping, tiny homes or accessory dwellings, so ask Butte County Planning about the exact parcel and unit12. Any dwelling still needs lawful wastewater: a county septic permit is required3. Where water or electricity is unavailable, South Dakota allows vault privies, chemical toilets, incinerator toilets or composting units, but all unconventional systems other than vault privies are experimental and need state plan approval before installation7. A permanent structure, including a tiny home on a foundation, falls under the county building permit outside city limits1.
What are the steps to build a home in Butte County?
Confirm whether the parcel is outside the limits of Belle Fourche, Newell and Nisland, then call Butte County Planning with the legal description and intended use.112
Get a 911 address and apply for the county septic permit with a licensed installer.3
Submit the building permit application with plans, site plan, proof of the septic permit and the $50 per structure fee.91
If the driveway is new, get the approach approval letter; if it connects to a state highway, get the state access permit before construction.1022
If the property is in a floodplain, also obtain a floodplain development permit.11
Determine whether a state water-right permit is needed; when it is, approval must come before well drilling.8
Arrange state electrical and plumbing permits and inspections, with the electrical final inspection before occupancy.1314
What should you check before buying land in Butte County?
Confirm the parcel is outside city limits, since the county rules apply only there1. Treat septic feasibility as a purchase contingency: only about 9.2% of mapped soils avoid severe drain-field limitations21. Butte County has about 4.8 people per square mile, and the nearest city of 100,000 or more is about 254 miles from the county center2324. For frontage on a state highway, South Dakota bars construction of a new or modified access until the permit is issued22. Floodplain parcels need permits, so ask Planning which floodplain administrator covers the parcel1125. The median property tax bill is about $2,197 per year at an effective rate of about 1.1%2627.
Watch-outs
Butte County says it has no zoning or code enforcement, but the county building permit still applies outside Belle Fourche, Newell and Nisland, so no zoning does not mean no permit.21
A large parcel does not erase septic rules: the 40-acre provision removes the engineer-design requirement for one system on one parcel, while the rest of the wastewater ordinance still applies.3
A qualifying owner may perform electrical work at an owner-occupied residence or farmstead, but the exemption is from licensure, not from the homeowner permit or inspections.6

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.”

Partial — South Dakota building-code standards for construction within local units of government, including unincorporated county areas.
“The design standard for construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal, and demolition of any building commenced after July 1, 2026, within the boundaries of any local unit of government that has not adopted an ordinance prescribing the standards pursuant to § 11-10-5, must be based on the 2024 edition of the International Building Code as published by the International Code Council, Incorporated. [...] The provisions of this section do not apply to any residential structure as defined in § 11-10-12, mobile or manufactured home, or farmstead and any accessory structure or building thereto.”
InspectionsRequired
Plumbing installations in South Dakota outside cities that administer their own plumbing inspection requirements.
The exception is for cities with their own inspection requirements.
Inspection requests generally require at least 72 hours advance notice, excluding weekends and holidays.
Inspections occur after a plumbing installation certificate is secured.
“You must have a plumbing inspection certificate for all plumbing installations.”

Limited — Electrical wiring installations subject to South Dakota Electrical Commission inspection.
“A final inspection is required for all jobs prior to occupancy.”
Off-grid sanitationAllowed (with conditions)
Unconventional off-grid sanitation systems where a water or electrical system is unavailable statewide.
Vault privies, chemical toilets, incinerator toilets, or composting units must be used when a water or electrical system is unavailable.
Except for vault privies, all unconventional systems are experimental systems and require plans and specifications submitted to the secretary for approval before installation.
“all unconventional systems are considered experimental systems”
Well permitLimited
Water-well drilling and proposed water uses statewide in South Dakota.
A water-right permit is required only for proposed water uses that fall within the permitting requirements; the official page directs applicants to the Using Water in SD page to determine whether a permit is needed.
When a water-right permit is required, state law requires approval before well drilling.
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
“If a water right permit is needed, state law requires the permit to be approved prior to doing any well drilling.”
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.)
“farmstead and any accessory structure or building thereto.”
Subdividing landRegulated (with conditions)
Division of a government subdivision or platted tract or lot, within or outside municipal corporate limits, into parcels for transfer when the parcels cannot be described except by metes and bounds.
The parcels must be platted into lots, numbered, and the plat recorded before any instrument of transfer may be recorded.
If an actual survey is necessary, the land must be surveyed and the plat recorded.
The requirement does not apply to parcels subject to a contract with the United States Secretary of Agriculture under the Conservation Reserve Program that are being transferred to or from the South Dakota Building Authority.
“within or without the corporate limits of any municipality [...] he shall cause the parcels of land so divided to be platted into lots”
Permit feesPublished (with conditions)
South Dakota state electrical wiring permits, including residential and farmstead wiring subject to state administration.
A wiring permit is required for electrical service entrances over 60 amperes, owner-exemption wiring, and other installations with an estimated inspection fee of at least $30.
Local inspection systems may have their own procedures, inspection fees, and regulations.
Inspection fees are separate from the $20 wiring-permit fee.
wiring permit fee: 20 USD · permit validity: 3 years (A new permit is required if the installation extends beyond three years.) · late permit administrative fee: 250 USD (Applies when the permit is not dated at job start or is not renewed before expiration.)
“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.
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:”
