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.

The local rulesMiller County, AR
Zoning & raw-land occupancy
Varies locallyUnincorporated Miller County appears to have no countywide zoning currently; a county comprehensive/land-use plan is being drafted via the Southwest Arkansas Planning and Development District. Land inside Texarkana, Fouke, or Garland city limits is zoned separately by those cities. source
Dwellings, tiny homes & RVs
Unclear - verifyNo Miller County ordinance on tiny homes or RV occupancy was confirmed for unincorporated land; within Texarkana city limits, the Planning Division handles occupancy permits and inspections.
Building permits & codes
Unclear - verifyNo dedicated Miller County building department or adopted building code was confirmed; residents are directed to city/town halls for permits, with the County Judge's office administering county ordinances generally. source
Septic & composting toilets
Generally allowedSeptic and onsite wastewater systems statewide, including Miller County, are permitted through the Arkansas Department of Health's Onsite Wastewater Program in cooperation with the local county Environmental Health Specialist. A narrow permit exemption exists for a single residence on ten or more acres with the system over 200 feet from any property line. source
Greywater reuse
RestrictedGreywater disposal is regulated under the same statewide ADH onsite wastewater framework; no Miller County-specific variance was found. source
Rainwater harvesting
Generally allowedNo Miller County ordinance addressing rainwater harvesting was found, so it appears to fall under the general unregulated state baseline.
Private wells & water rights
Generally allowedPrivate well construction is standardized by the Arkansas Department of Health statewide; no separate Miller County well ordinance was confirmed. source
Living disconnected from utilities
Unclear - verifyNo official Miller County or city source was found requiring hookup to electric, water, or sewer utilities, though onsite wastewater must still meet ADH permit standards regardless of grid status. source
