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 rulesHot Spring County, AR
Zoning & raw-land occupancy
Unclear - verifyNo official Hot Spring County zoning ordinance for unincorporated land was found. The City of Malvern has its own zoning and subdivision code, but it only applies inside Malvern's city limits. source
Dwellings, tiny homes & RVs
Unclear - verifyMalvern's code addresses manufactured homes within city limits, but no Hot Spring County ordinance on tiny homes or RV residency in unincorporated areas was located.
Building permits & codes
Unclear - verifyA commercial directory lists a Malvern Building Department for city permits, but no official Hot Spring County building-permit office for unincorporated land was confirmed. State law requires any permitting city or county to adopt the Arkansas Energy Code, but it's unconfirmed whether the county issues permits at all. source
Septic & composting toilets
Generally allowedThe Arkansas Department of Health's statewide Onsite Wastewater program, administered locally through the county health unit's Environmental Health Specialist, permits septic systems. A narrow exemption exists for a single residence on ten-plus acres with the system over 200 feet from all property lines. source
Greywater reuse
RestrictedGreywater is governed by the same ADH Onsite Wastewater Rule as septic systems. No separate Hot Spring County ordinance was found. source
Rainwater harvesting
Generally allowedNo Hot Spring County ordinance on rainwater collection was found, so this defers to Arkansas's generally permissive state baseline for outdoor collection.
Private wells & water rights
Generally allowedThe Arkansas Department of Health sets statewide well-construction standards. No separate Hot Spring County well ordinance or water authority page was found; the local Onsite Environmental Specialist office coordinates well siting. source
Living disconnected from utilities
Unclear - verifyNo Hot Spring County ordinance requiring utility hookup was found. In practice, the binding requirement is an ADH-approved sewage system, not a utility connection.
