Alternative Housing Notes

Tiny Homes

Madison County official building permit materials and county website context identify county building and planning/zoning review. Tiny home feasibility should be checked through county building, planning and zoning, septic, water, access, subdivision status, and Rexburg or other city jurisdiction before purchase.

RV Living

RV or camper occupancy should be confirmed directly with Madison County because permit applications do not establish blanket long-term RV living permission.

Off Grid

Off-grid projects should verify building permits, planning and zoning review, legal access, septic, well or water source, winter access, agricultural context, city boundaries, and private restrictions before relying on rural acreage.

Container Homes

Container homes should be reviewed as dwelling or structure proposals through county building and planning/zoning review before relying on a parcel.

ADUs

ADU feasibility should be checked against county planning and zoning requirements, parcel size, utilities, septic capacity, access, city boundaries, and private restrictions.
