Read this before you act on anything below. This is my researched starting point for Hughes 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 rulesHughes County, SD

Zoning & raw-land occupancy

Varies locallyHughes County has countywide zoning (Agricultural Districts A, B, B2, plus PUD option) administered by the Planning and Zoning Department, but this only applies outside Pierre, Blunt, and Harrold city limits (and Pierre's ETJ), where municipal zoning governs instead. source

Dwellings, tiny homes & RVs

RestrictedPermanent RV or tiny-home living isn't clearly allowed; the county only confirms a conditional-use permit for temporary 'Long Term Private Camping' while building a house, per Ordinance 2013-03. Standalone tiny-home-as-primary-residence rules are not confirmed, so ask Planning and Zoning. source

Building permits & codes

RestrictedHughes County has adopted an ICC-based building code (Ordinance 2019-5) covering structural, sanitation, and utility standards, with permits mandatory outside the exempt municipalities. Fee amounts were updated in 2023 but aren't detailed in this research; confirm current fees with the department. source

Septic & composting toilets

Generally allowedSeptic systems are permitted and inspected at the county level by Planning and Zoning, but design and installation standards are set by the state DANR under its administrative rules for on-site wastewater systems. Composting toilets are not addressed in either county or state material found. source

Greywater reuse

Unclear - verifyNo Hughes County ordinance or South Dakota DANR rule specifically addressing residential greywater reuse was found; this is an open question for the county building/septic official.

Rainwater harvesting

Unclear - verifyNo Hughes County-specific ordinance on rainwater harvesting was found, and state guidance is limited to water-rights exemptions for domestic use rather than rainwater collection specifically.

Private wells & water rights

Generally allowedWells are regulated at the state level by DANR: a water right permit is generally required before drilling, except for domestic use under certain volume/pump-rate limits, and a licensed well driller must do the work. No distinct Hughes County well ordinance was found. source

Living disconnected from utilities

Generally allowedLiving disconnected from public utilities isn't separately prohibited, but Hughes County's building code (Ordinance 2019-5) still requires compliant water supply and sewage disposal per code, so an off-grid dwelling must meet those standards even without grid electric or municipal hookups. source
