Off-Grid Living in Gregory County, South Dakota

I'll be straight with you: Gregory County, South Dakota isn't one of those "no zoning, do what you want" rural counties some off-gridders dream about. The county has adopted a countywide zoning ordinance, and it's enforced by a Zoning Administrator under the Planning Commission. That's a meaningful difference from neighboring counties that have never adopted zoning at all, so don't assume South Dakota is a free-for-all just because you've heard that about parts of the state.

Zoning and permits. Per the county's own material, "No building or other structure shall be erected, moved, added to, or use changed without a permit issued by the Zoning Administrator," and building without one carries a daily fine. That's a county-level rule, not a state one. I also found Planning Commission minutes discussing whether to allow building on parcels smaller than 40 acres, which tells me minimum acreage requirements exist in some zones and are actively being debated, so don't assume any specific number without asking directly.

Tiny homes, RVs, dwelling type. I could not confirm any Gregory County ordinance language specifically addressing tiny homes or RV living. The general "any structure needs a permit" rule likely applies, but how the county classifies and treats these dwelling types isn't settled in what I found. Ask the Zoning Administrator before you commit to a build.

Building codes. The county requires a permit, but whether it's adopted a specific building code edition wasn't confirmed on the county site. Statewide, any jurisdiction that does adopt a code must align with the 2021 IBC, but enforcement decisions are made locally.

Septic. South Dakota's Department of Agriculture and Natural Resources (DANR) sets statewide standards for septic installation, requiring certified installers. Whether Gregory County itself issues the local septic permit or defers to the state wasn't confirmed, call the Zoning Administrator to find out how it actually works on the ground.

Greywater and rainwater. I found no Gregory County or state rule specifically addressing residential greywater reuse or rainwater harvesting. That's genuinely unclear territory, not a green light, just an absence of a found rule.

Wells. This one's cleaner: wells are regulated by DANR statewide, a licensed well driller is required, and most household use is exempt from needing a separate water-right permit unless you exceed fairly high daily or per-minute thresholds. No county-specific well rule was found, so the state framework is what governs.

Utilities. No Gregory County rule bars living disconnected from the grid. Electrical work is licensed through the state Electrical Commission, with an owner's exemption for your own residence, and that applies regardless of county.

One more thing worth remembering: incorporated towns inside the county (Gregory, Burke, Bonesteel, Fairfax, Dallas, Herrick) each run their own municipal codes, separate from the county's. If you're eyeing land inside town limits, county rules won't be the whole story.
