Read this before you act on anything below. This is my researched starting point for Miner County, SD, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesMiner County, SD

Zoning & raw-land occupancy

RestrictedMiner County has adopted a full countywide zoning ordinance under SDCL 11-2, dividing unincorporated land into districts (Agricultural, FloodPlain Overlay, Aquifer Protection Overlay, Commercial/Industrial, Town, Planned Residential). This is more regulated than counties with no zoning at all, so where you can put a place and what you can do with raw land depends on the district; check with the Zoning Administrator before you buy or build. source

Dwellings, tiny homes & RVs

Unclear - verifyI could not find specific language in the zoning ordinance addressing tiny homes or RVs used as full-time residences. The ordinance defines 'building' broadly, but you'll need to call the Miner County Zoning Administrator (also the Director of Equalization) directly to find out how they treat these structures in each district. source

Building permits & codes

RestrictedMiner County requires a building permit, issued through the Director of Equalization acting as Zoning Administrator. There's a fillable application on the county's zoning page, but I didn't find a published fee schedule or code edition, so confirm those specifics with that office. source

Septic & composting toilets

Generally allowedSeptic systems are governed by South Dakota's statewide rules under ARSD Chapter 74:53:01, administered through DANR with installer certification, and it appears county staff (likely the Zoning/Equalization office) handle local site visits and approvals. No Miner County-specific septic ordinance turned up in my research, so confirm local administration details with the county. source

Greywater reuse

Unclear - verifyI found no Miner County ordinance or South Dakota state rule specifically addressing residential greywater reuse. This is a gap you'd need to ask the county Zoning office about directly.

Rainwater harvesting

Unclear - verifyThere's no Miner County or DANR page I found that specifically addresses rainwater harvesting for domestic use. South Dakota's domestic-use exemption from water-right permitting may be relevant, but nothing county-specific was confirmed, so ask the county or DANR Water Rights office directly.

Private wells & water rights

Generally allowedWells fall under the state's Water Rights Program: a licensed well driller is required, and domestic use is generally exempt from needing a water-right permit unless it exceeds set thresholds (25,920 gallons per day or 25 gpm). Miner County's Aquifer Protection Overlay District may add its own siting standards, so check with the county Zoning Administrator on top of the state process. source

Living disconnected from utilities

Varies locallyNothing in South Dakota law or the Miner County ordinance text I reviewed bans living off the grid or disconnected from utilities. But the county's zoning districts, especially the Aquifer Protection Overlay, could carry additional standards affecting off-grid setups, so it's worth a direct call to the Zoning Administrator before you commit to a site. source
