Off-Grid Living in Moody County, South Dakota

I've been digging into what off-grid living actually looks like in Moody County, South Dakota, and the short version is: this is one of the counties that has opted into zoning, so you're dealing with real local rules on top of the state baseline, not just open land with no oversight.

Zoning. Moody County has adopted its own countywide Zoning Ordinance (Ordinance #2020-02, as amended), administered by a Planning & Zoning Board that's made up of the county's Board of Commissioners, with a Zoning Administrator handling the day-to-day work. Unincorporated land is split into districts, Agricultural, Commercial/Industrial, Lake Park, Natural Resources, and Planned Residential, plus a Floodplain Overlay. Where you land in that district map matters a lot for what you can do, so a call to the Zoning Administrator before you buy land is worth it.

Dwellings, tiny homes, RVs. The ordinance has dedicated chapters on modular and manufactured homes, permanent foundations required for dwellings, and moved-in buildings. That tells me a tiny home or RV used as a year-round residence likely needs to meet foundation and manufactured-home standards, not just get parked on a lot. I could not confirm exact RV occupancy thresholds from what's available online, so ask the Zoning Administrator directly.

Building permits/codes. The county's Planning and Zoning office issues building permits, 911 addresses, and handles conditional use permits and variances. South Dakota doesn't mandate a uniform statewide building code, and I couldn't confirm whether Moody County has formally adopted a specific IBC/IRC edition, so ask before you plan construction.

Septic. This is state-regulated under DANR's Administrative Rules (Chapter 74:53:01), with installer certification required, and the county ordinance has its own septic chapter confirming local administration of that state design standard. Composting toilets aren't separately addressed anywhere I found.

Greywater and rainwater. Both are genuinely unconfirmed. I found no county or state page directly addressing residential greywater reuse or rainwater harvesting here, which doesn't mean it's banned, it means you should ask the county and DANR directly before you build a system.

Wells. These fall under state jurisdiction, licensed well contractors work under DANR's well construction standards (ARSD 74:02). I found no Moody-County-specific well ordinance layering on top of that.

Utilities. No county rule bars living disconnected from the grid, as far as I could confirm. State electrical licensing through the SD Electrical Commission still applies to any wiring work regardless of grid status.

Bottom line: Moody County is more hands-on than a no-zoning county, so plan on talking to the Zoning Administrator early, and treat septic/well/electrical as governed by clear state rules with county administration layered on top.
