Off-Grid Living in Madison County, Mississippi

If you're eyeing a piece of land in Madison County, Mississippi for an off-grid setup, the first thing I have to flag is a scope issue: most of the county is unincorporated, but Madison, Ridgeland, Canton, Flora, and Gluckstadt are all separate cities with their own zoning and building departments. Everything below is about the unincorporated county, governed by the Madison County Board of Supervisors through its Planning and Zoning Department. If your parcel sits inside one of those city limits, throw this out and call the city instead.

Zoning. Unlike a lot of rural Mississippi counties, unincorporated Madison County actually has a countywide zoning ordinance, administered by Planning and Zoning. What's allowed on raw land depends on the district you're in, and the ordinance has conditional/special-exception processes for uses that don't fit neatly. I couldn't pin down from the ordinance text exactly which districts welcome off-grid homesteading outright, so that's a call-and-ask situation.

Dwellings, tiny homes, RVs. The zoning ordinance defines manufactured/mobile homes and has a whole article on Manufactured Home Park Residential Districts, including inspection requirements. What's murkier is full-time living in a tiny home on wheels or an RV outside a designated park. I saw commercial (non-official) sources claiming that's treated as temporary RV use and restricted to RV parks, but I couldn't confirm that directly against the county's own ordinance language, so I'm calling this restricted with real uncertainty. Confirm with Planning and Zoning before you commit.

Building permits. The same Planning and Zoning Department handles permits and inspections for unincorporated county construction, so it's a one-stop office for both zoning approval and building sign-off.

Septic and composting toilets. Septic systems fall under the Mississippi State Department of Health's statewide On-Site Wastewater program, which does the soil and site evaluations required before you can even get a water meter. I didn't find a Madison County-specific health department page separate from the state site, so route septic questions through MSDH's wastewater call center.

Greywater and rainwater. No county ordinance on either topic turned up in my research. That means the state's default posture applies: greywater is treated cautiously (essentially like sewage needing approved disposal), while rainwater harvesting is generally fine with no county pushback found.

Wells. Domestic wells are permitted, but plan on the same MSDH environmental health review tied to your septic evaluation, plus a state-licensed well driller. No county water authority page came up in my search.

Grid disconnection. I found nothing in Madison County's ordinance addressing whether you can fully disconnect from utilities. Mississippi's general baseline allows off-grid power generation, but full disconnection can bump into code or occupancy expectations, so I'd confirm directly with Planning and Zoning rather than assume.

Bottom line: Madison County isn't a lawless off-grid frontier, it has real zoning and permitting infrastructure, but several of the details that matter most to off-gridders (RV living, greywater, disconnection) aren't spelled out in what I could find. Call before you build.
