A building permit in unincorporated Minnehaha County is issued by the county's Planning and Zoning Department, which adopted the International Residential and Existing Building Codes and inspects new construction — so this county is a real building authority, unusual in a state where many counties enforce no building code at all.
Two things shape a Minnehaha County project. The unincorporated county is overwhelmingly zoned Agricultural, and the zoning ordinance regulates how many dwellings may be built on an agriculturally zoned parcel, so the number and placement of houses is a zoning question before it is a building one. And while the county inspector handles footing, framing and final, the electrical inspection is the state's, reflecting South Dakota's statewide electrical program.
This guide covers the unincorporated area of Minnehaha County. Sioux Falls and other incorporated cities run their own departments and issue their own permits; confirm the address is unincorporated before filing with the county.
Zoning decides the house before the building code does. Because most of unincorporated Minnehaha County is zoned Agricultural and the ordinance limits the number of dwellings on such a parcel, confirming the zoning and how many houses the parcel may carry is the first step — ahead of the building permit itself.
What requires a building permit in Minnehaha County?
So in Minnehaha County the questions are whether a building code is enforced at all, which edition it is on, and how the county's agricultural zoning limits where a house may go, and that the county inspects the building while the state inspects the electrical.

Whether a building code is enforced where you are building
Minnehaha County enforces adopted International Codes — the 2021 Residential and Existing Building Codes among them — and issues building permits in the unincorporated area, which most South Dakota counties do not. Two county features stand out: the vast majority of the unincorporated county is zoned Agricultural, where the ordinance limits how many houses a parcel may carry, and the county inspects footing, framing and final while the electrical inspection is done by the state inspector.
South Dakota has no state-enforced building code: each city or county decides whether to adopt one. The state Electrical and Plumbing Commissions permit and inspect those trades, except in a few cities that run their own inspections. South Dakota rules
Who handles permitting in Minnehaha County?
Unincorporated Minnehaha County is served by the county Planning and Zoning Department in the county Administration Building in Sioux Falls, which issues zoning and building permits, enforces the adopted codes, and inspects construction outside city limits. A separate county building inspector line handles inspection scheduling; electrical and plumbing are permitted through the state.

Permit types
Residential permits
New houses, additions, remodelling and certain structural repairs in the unincorporated county need a building permit from Planning and Zoning, and detached accessory structures under 120 square feet are exempt, though setbacks still apply. The county inspects footing, framing and final; the electrical inspection is the state's.
Commercial permits
Commercial and agricultural-support construction is reviewed under the county’s adopted codes, with the zoning ordinance controlling use and placement. Schools, day care centres for 21 or more children, group family day care homes (13 to 20 children) and fuel or LP-gas storage installations additionally need State Fire Marshal plan approval, and electrical and plumbing run through the state commissions.
The state permits that run regardless of local code
In Minnehaha County the county building inspector handles footing, framing and final, but the electrical inspection is carried out by the state, and plumbing is permitted by the state commission.
South Dakota licenses electricians and plumbers at state level but has no state general contractor licence; a city may add its own. South Dakota rules
Minnehaha County permit costs and fees
Minnehaha County scales its building permit to the project and issues the zoning permit alongside it. The costs particular to the county are the separate state electrical and plumbing permits, which are not billed by the county.
Rather talk it over?
Call 1-855-478-4290 →| Item | Fee or rule |
|---|---|
| Building permit | Scaled to the project under the county's fee schedule and confirmed at intake |
| Zoning permit | Issued alongside the building permit; agricultural zoning governs dwelling count and placement |
| County inspections | Footing, framing and final carried out by the county building inspector |
| Electrical and plumbing | Permitted and inspected by the state, billed separately from the county |
The state inspects the wiring, not the county. Even though Minnehaha County runs a full building department, the electrical inspection is the state's and plumbing is permitted by the state commission, so those fees and inspections sit outside the county building permit.
Trade permits and who may pull them
Permit required
- Electrical — by a licensed electrician, or by the owner in their own owner-occupied home or farmstead, permitted and inspected by the South Dakota Electrical Commission (by the city in Sioux Falls and Rapid City)
- Plumbing — by a licensed plumber, or by the owner in their own home, permitted and inspected by the South Dakota Plumbing Commission (by the city in Aberdeen, Brandon, Rapid City, Sioux Falls and Spearfish)
- Mechanical and fuel gas — under the code edition the city has adopted, where it enforces one
- Fire protection — to the standard the State Fire Marshal or the city fire code sets for the occupancy
Typically exempt
- Building trades in a jurisdiction that enforces no building code, beyond the state electrical and plumbing permits
- Like-for-like replacement not amounting to a new installation
Electrical and plumbing permits come from the state commissions, except in a few cities that issue their own. South Dakota rules

Cities with building departments enforce their adopted code; many counties and small towns enforce none, and then there is no local building permit.
The city inside its limits, the county in unincorporated areas only if it has adopted a code, or no one for building work.
Where a code applies, state law sets the edition, but each city makes its own amendments — Sioux Falls and Rapid City are not the same.
From the South Dakota Electrical Commission and Plumbing Commission, except in the few cities that run their own electrical or plumbing inspections.
Required for schools, day care centres, group family day care homes and fuel or LP-gas storage installations.
City or county inspections where a code is enforced, state electrical and plumbing inspections except in the few cities that do their own, then the certificate of occupancy where a code applies.
Review, corrections and what actually causes delay
The Minnehaha County delays that recur are zoning delays: an agriculturally zoned parcel that cannot carry an additional dwelling, or a placement that fails the setback. Settling the zoning and dwelling-count question before the building permit, and lining up the state electrical and plumbing permits, keep the county review on track.
Inspections in Minnehaha County
Where a city enforces a code, inspections follow the sequence in its adopted edition — footing, foundation, framing, rough trades, insulation and final — requested from the city against the permit number. Electrical and plumbing inspections are separate: they are carried out by the state commissions, and their approvals are what the city and, where it is involved, the State Fire Marshal rely on. Where a jurisdiction enforces no building code, the state electrical and plumbing inspections may be the only ones the work receives. A certificate of occupancy closes the file where a code is enforced. In Minnehaha County the footing, framing and final inspections are carried out by the county building inspector against the permit number, while the electrical inspection is done by the state inspector and plumbing is inspected by the state commission.

Frequently asked questions
Does Minnehaha County require a building permit?
Yes, in the unincorporated area. Unlike many South Dakota counties, Minnehaha County runs a building department, adopted the International Residential and Existing Building Codes, and issues permits and inspects construction. Cities inside the county issue their own permits.
How does agricultural zoning affect building a house?
Most of the unincorporated county is zoned Agricultural, and the zoning ordinance limits how many dwellings may be built on such a parcel. The number and placement of houses is a zoning question that comes before the building permit.
Inspections are where schedules slip.
Get a free quote →Who inspects the electrical work?
The state. Minnehaha County inspects footing, framing and final, but electrical inspections are carried out by the state inspector, and plumbing is permitted and inspected by the state commission.
Which building codes does the county enforce?
Adopted International Codes including the 2021 Residential and Existing Building Codes. Confirm the current editions and county amendments with Planning and Zoning before you design to them.
Do I need a permit for a small shed?
Detached accessory structures under 120 square feet are exempt from the building permit, but zoning setbacks still apply. Confirm the current threshold with Planning and Zoning first.
Does the State Fire Marshal review my project?
Only for the occupancies within its narrow reach — schools, day care centres for 21 or more children, group family day care homes (13 to 20 children) and fuel or LP-gas storage installations. Most county projects do not draw a State Fire Marshal review.
