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 rulesMontgomery County, NC
Zoning & raw-land occupancy
RestrictedMontgomery County has adopted a countywide Zoning Ordinance administered by the Planning Department, with classifications set by the Board of Commissioners; this is not a no-zoning county. source
Dwellings, tiny homes & RVs
Varies locallyRVs and campgrounds are governed by separate county ordinances (RV Resort, Twin Harbor Campground); general tiny-home rules aren't confirmed at the county level, so the state Appendix Q baseline is presumed to apply, but confirm with Planning. source
Building permits & codes
Generally allowedBuilding permits are mandatory under the NC State Building Code, administered by the county Inspections Department (Central Permitting), and require proof of an approved wastewater method before issuance. source
Septic & composting toilets
Generally allowedSeptic systems are permitted through county Environmental Health, the state-delegated local authority under NC's onsite wastewater rules; composting toilet policy specific to the county is not confirmed. source
Greywater reuse
RestrictedNo county-specific greywater program was found; the state's general regulatory baseline applies by default, and local variance is not confirmed.
Rainwater harvesting
Generally allowedNo county-specific restriction or ordinance was found on rainwater harvesting, so the generally permissive state baseline applies.
Private wells & water rights
Generally allowedPrivate well construction permits and water sample testing are issued by county Environmental Health, consistent with the statewide 2008 delegation of well permitting authority to local health departments. source
Living disconnected from utilities
Unclear - verifyNo standalone ordinance bans off-grid living, but building permits functionally require proof of an approved sewage method, which likely blocks fully off-grid new construction; whether a well-and-septic home with no electrical hookup can get a certificate of occupancy is not confirmed and is handled case-by-case by Inspections. source
