Off-Grid Living in Stanley County, South Dakota

Stanley County, South Dakota is one of the more zoned-and-regulated pockets of the state when it comes to off-grid living, at least on paper. Here's what I found researching official sources, with the caveat that some questions (tiny homes, greywater, rainwater) simply aren't answered anywhere in writing yet, and you'll need to call the county directly.

First, a jurisdictional note: this brief covers unincorporated Stanley County. If your land is inside Fort Pierre city limits or within its one-mile extraterritorial zoning radius, the City of Fort Pierre governs instead, not the county.

Zoning. Unlike some rural counties that have no zoning at all, Stanley County has adopted a countywide zoning ordinance under state law (SDCL 11-2). The Planning & Zoning Administrator handles building permits, variances, and rezoning, and the County Commission approves plat and ordinance changes. So don't assume "rural" means "unregulated" here.

Dwellings, tiny homes, RVs. I couldn't find a Stanley County page that specifically addresses tiny homes or living in an RV on raw land. Given the county's general permit trigger for any structure, I'd assume some kind of permit or review applies, but the details aren't confirmed. Call Planning & Zoning before you set anything up.

Building permits. The county requires a building permit before erecting, moving, adding to, or changing the use of any structure, anywhere in the county outside Fort Pierre's zoning radius. Applications go through the Equalization Office at the County Courthouse. South Dakota has no mandatory statewide residential code, but any local code adopted has to align with the state's 2021 IBC baseline.

Septic and composting toilets. Onsite wastewater systems are regulated statewide by DANR, with design standards meant to protect health and the environment. Permitting is typically administered county by county; for Stanley County, this appears to run through Planning & Zoning, though I didn't find a dedicated septic page from the county itself, so confirm directly.

Greywater. Not confirmed for Stanley County specifically. I did find that South Dakota regulations generally prohibit discharging untreated wastewater onto the ground surface (confirmed via a Minnehaha County government FAQ referencing the statewide rule), but nothing Stanley County-specific exists in writing that I could locate.

Rainwater harvesting. No county or state rule addressing this directly was found. It may intersect with water-use permitting only if usage is heavy (see wells, below), but simple catchment doesn't appear to be separately regulated.

Wells. DANR's Water Rights Program sets statewide well construction standards, and domestic use is exempt from water-right permits unless you exceed 25,920 gallons per day or a 25 gallon/minute peak rate. No Stanley County-specific well rule was found, so the county appears to defer to the state entirely.

Utilities. No rule bans living off-grid or disconnected from utilities outright, but any structure still needs a building permit, and electrical work is subject to statewide licensing (with an owner's exemption for your own residence).

Bottom line: Stanley County is genuinely zoned, permits matter, and several everyday off-grid questions (greywater, rainwater, tiny homes) just aren't spelled out publicly, so a phone call to Planning & Zoning will save you guessing.
