Building permits, zoning and land rules in Perkins County, South Dakota

Yes. Within the Perkins County planning jurisdiction shown on the official zoning map, the appropriate zoning permit is required before a land use begins or changes and before a structure is erected or moved¹. Building/Use Permit applications require newspaper notice and a 14-day public-comment period; conditional uses add Planning Commission review, notice to adjoining owners and County Commission consideration¹. The Planning and Zoning Director may inspect a proposed site at a reasonable time after notifying the applicant¹.

A fee is due with a zoning-permit, variance or ordinance-amendment application, but the amount is set by County Commission resolution rather than stated in the ordinance¹. We could not confirm a separate Perkins County building-code adoption, general construction-inspection program or certificate-of-occupancy requirement. South Dakota's building-code framework identifies model codes, but local adoption and enforcement for a Perkins County project were not established⁷. Covered plumbing and electrical work can still require state permits and inspections^8,9.

Perkins County's ordinance assigns zoning-permit applications to the Planning and Zoning Department, while the county Finance Office is the verified public contact for routing a caller to the current zoning official^1,10. The Finance Office is at PO Box 126, Bison, SD 57620 and lists 605-244-5624 as its auditor phone¹⁰.

Request the appropriate county form and the list of materials for the permit type¹. Ask for the current fee resolution because a fee is required but no amount appears in the ordinance¹. Building/Use Permit applications have a 14-day public-comment period, while conditional-use applications require additional review and public notice¹. A zoning permit expires if the authorized building or use does not begin within 365 days, although a written extension of up to 180 days may be available¹. State plumbing, septic and electrical requirements remain separate from county zoning approval^2,8,9.

Yes. The Perkins County ordinance governs land within the County Commissioners' planning jurisdiction shown on the official zoning map, and the commissioners administer and enforce it¹. The ordinance establishes the General Agricultural District¹. A primary structure in that district needs a lot of at least 39 acres¹. The general district standards call for 25-foot setbacks and a 35-foot maximum structure height, with use-specific exceptions¹.

A proposed agricultural building avoids a Building/Use Permit only if it is in the General Agricultural District, is on at least 39 acres or a parcel in a larger contiguous agricultural operation, stands at least 100 feet from every property line or public road, and serves an existing or clearly potential agricultural use¹. We could not confirm a county minimum dwelling size, lot-coverage rule, accessory-dwelling rule or operative subdivision ordinance, so ask Planning and Zoning before fixing a house site.

South Dakota sets minimum requirements for on-site wastewater systems, and local governments may impose stricter requirements². A conventional individual system may be designed and installed under the state chapter without submitting plans for advance state approval; other installations receiving human waste require state review and approval before construction, and installers must be certified by the South Dakota Plumbing Commission¹¹. The state or its authorized representative may inspect an on-site system at any time, but the rule does not establish a universal pre-operation inspection¹¹.

A septic system cannot be installed or operated where public wastewater is available, which requires the parcel to be within a municipality or sanitary district, a sewer collection system within 400 feet, and a request from that municipality or district to provide service¹¹. The state septic program answers on-site wastewater questions at (605) 773-4647¹². Only 7.6% of mapped county soils are rated without severe limitations for a conventional drain field, so obtain a parcel-level site evaluation and confirm whether county rules add review before excavation¹³.

Within Perkins County's mapped planning jurisdiction, a commercial RV park in the General Agricultural District requires a Conditional Use Permit, and an RV-park stay may last no more than 30 days¹. That rule does not answer whether long-term RV occupancy is allowed on an ordinary private parcel outside an RV park, so ask Planning and Zoning for a written parcel-specific answer¹.

A tiny home can use the single-dwelling framework if it qualifies as a dwelling unit with independent sleeping, cooking and sanitation facilities; a Building/Use Permit is required in the General Agricultural District¹. If a proposed tiny-home use does not fit an ordinance definition or the applicable use table, the use is prohibited; a use variance is unavailable, but the owner may seek an ordinance amendment¹. We could not confirm a minimum dwelling floor area or accessory-dwelling rule, so get the county's classification in writing before ordering a structure.

1. Give the Finance Office the parcel description and project concept, and ask for the current Planning and Zoning contact¹⁰.

1. Confirm that the parcel is within the mapped planning jurisdiction, then verify its zoning designation and allowed use; primary structures in the General Agricultural District require at least 39 acres¹.

1. Request the correct application and fee resolution, then submit the required materials early enough for public notice and review¹.

1. Obtain the zoning permit before beginning or changing the use or erecting or moving a structure; verify every condition before relying on the agricultural-building exemption¹.

1. Determine whether public wastewater is available before designing septic; if not, confirm whether the proposed system requires state plan approval¹¹.

1. Confirm water, plumbing and electrical requirements; an owner doing qualifying electrical work may avoid licensure but still needs the homeowner permit and inspections^4,6,8.

1. An owner building solely for personal use without intending to sell or lease may avoid a contractor's excise-tax license for the owner's own work, while hired contractors still owe the tax on their receipts⁵.

1. If the driveway enters a state highway, obtain state permission before access construction¹⁴.

Begin with legal buildability, wastewater, water and access. Perkins County has about 1 person per square mile, and the nearest city of 100,000 or more is about 281 miles from the county center¹³. That remoteness makes contractor availability, hauling distance and emergency planning practical parts of a building budget.

For wastewater, only 7.6% of mapped soils avoid a severe conventional-drain-field limitation, so obtain a parcel-level site evaluation before committing to a house location¹³. For water, confirm likely well conditions and whether the intended use needs a water-right permit before drilling⁶. If access is from a state highway, construction cannot start until the state access permit is issued¹⁴. Ask the county whether the parcel lies in a regulated floodplain because participating South Dakota communities require permits for floodplain development¹⁵. Finally, treat the county's 1.3% effective property-tax rate and $1,405 median annual bill as context, then obtain the parcel's assessment and actual tax history¹³.
