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 rulesCatawba County, NC
Zoning & raw-land occupancy
Varies locallyUnincorporated county land follows the county's Unified Development Ordinance administered by Planning, Parks and Development, but eight towns (Brookford, Catawba, Claremont, Conover, Hickory, Long View, Newton, Maiden) apply their own zoning within limits/ETJ. Always confirm which jurisdiction covers your parcel. source
Dwellings, tiny homes & RVs
RestrictedA zoning permit with site drawings is required before building, and manufactured homes must follow the state Manufactured/Mobile Home Code setup process. Specific numeric limits on RVs or tiny homes were not confirmed in official sources, so ask Planning directly. source
Building permits & codes
Generally allowedCatawba County Building Services enforces the statewide NC Building Code countywide, including inside all eight municipalities, with staged inspections like a footing inspection before concrete is poured. source
Septic & composting toilets
Generally allowedSeptic systems are permitted and supervised by the county's Environmental Health On-Site Wastewater Program under state rules, but zoning approval must happen before a septic application is processed. Composting toilet policy specifically was not confirmed. source
Greywater reuse
Unclear - verifyNo county-specific greywater ordinance or program was found; this likely defaults to the state DEQ/DHHS framework. Not confirmed beyond that, so check with County Environmental Health.
Rainwater harvesting
Generally allowedNo county restriction on rainwater harvesting was found; state law generally protects collection. Not confirmed whether the county has added any local rule.
Private wells & water rights
Generally allowedWells are permitted through County Environmental Health under state well construction standards, using the same application system as septic permits. source
Living disconnected from utilities
Unclear - verifyNo explicit county ban on disconnecting from utilities was found, but because septic requires zoning approval first and building permits are mandatory countywide, fully off-grid occupancy runs into practical hurdles rather than a clear legal bar. source
