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 rulesBrunswick County, NC
Zoning & raw-land occupancy
Varies locallyBrunswick County Planning & Community Enforcement administers the county UDO for unincorporated areas under NC Chapter 160D, but incorporated towns like the City of Northwest have their own separate zoning ordinances. source
Dwellings, tiny homes & RVs
Varies locallyThe county follows state residential code minimums and offers tiny-home guidance, but no separate county minimum size was found; RV use as a standalone residence is not confirmed by an official county source. source
Building permits & codes
Generally allowedBrunswick County Code Administration handles building permits and inspections, applying state code and allowing stricter local rules only where state law permits it. source
Septic & composting toilets
Generally allowedBrunswick County Environmental Health Services requires an Improvement Permit Application, a site evaluation, and Construction Authorization and Operation Permits, following adopted state health rules; composting toilets are not separately addressed. source
Greywater reuse
Unclear - verifyNo Brunswick County-specific greywater page was found; this defaults to state DEQ/DHHS rules, so confirm directly with county Environmental Health.
Rainwater harvesting
Unclear - verifyNo county ordinance restricting rainwater harvesting was found; state law generally protects the practice, but there's no dedicated Brunswick County policy page to cite.
Private wells & water rights
Generally allowedBrunswick County Environmental Health issues well permits, typically required alongside a septic permit application when a property lacks public water. source
Living disconnected from utilities
RestrictedThere's no outright ban on going off-grid, but zoning, building permits, and approved water/wastewater review are all cross-referenced and generally required together, with no standalone off-grid homestead category identified. source
