Buying Land in Perkins County, South Dakota

No confirmed zoning -- a comprehensive plan is not the same thing

Perkins County appears to fall on the unzoned side of the divide the state hub describes: while the county commission worked with the Black Hills Council of Local Governments to draft a county Comprehensive Plan (approved for review at the County Courthouse in Bison after a Planning Committee recommendation), we could not find any separate, adopted zoning ordinance, zoning district map, or dedicated Planning & Zoning department for the county -- unlike Grant, Hughes, Minnehaha, Moody, and Pennington Counties, all of which publish an actual zoning ordinance document. Under South Dakota Codified Laws Chapter 11-2, a comprehensive plan and a zoning ordinance are two separate steps: a county can adopt the former as a policy guide without ever adopting the latter as an enforceable regulation. That distinction matters directly for a land buyer -- a comprehensive plan describes intended future land use in general terms, but without an adopted zoning ordinance, there's no enforceable zoning district, permitted-use table, or rezoning process to check for a specific parcel. Confirm current zoning status directly with the Perkins County Auditor's office or Board of Commissioners before assuming either way.

A shrinking, ranching-dominated county on the northwestern border

Perkins County is large by South Dakota standards and sparsely populated, sitting on the state's northwestern border with both North Dakota and Montana, with Harding County to its west. Its population trajectory runs opposite to the growth story playing out in counties like Minnehaha and Pennington: the county has lost population in every recent decade, falling from 3,363 residents in 2000 to 2,835 at the 2020 Census, with both of its towns -- Lemmon (the largest city, down to 1,160 residents from a 1950 peak of 2,760) and Bison (the county seat, down 9.3% between 2010 and 2020 to 302 residents) -- individually shrinking as well. For a land buyer, that decline shapes practical realities distinct from a growth-market county: fewer comparable sales, thinner local demand for residential development, and land values driven primarily by agricultural production value rather than development or subdivision potential.

That agricultural character is the county's defining economic feature: roughly 79% of Perkins County's land is in agricultural use, with cattle ranching and wheat farming forming the core of the local economy and Agriculture, Forestry, Fishing & Hunting the county's largest employment sector. Some regional reports have noted moderate oil and gas exploration potential in the broader northwestern South Dakota area, but the productive Bakken shale formation to the north does not extend into South Dakota, so unlike land near the North Dakota border on the other side of the state line, mineral leasing activity has not developed into a significant land-use or land-value factor here. A Perkins County land purchase is, in practice, primarily a ranching or dryland-farming decision -- evaluate accordingly, and confirm mineral ownership through a standard title search rather than assuming oil and gas potential either way.
