Off-Grid Living in Lowndes County, Mississippi

I've been digging into what it actually takes to live off-grid in Lowndes County, Mississippi, and here's my honest read after going through the official sources I could find.

First, the big picture: Lowndes County (county seat Columbus) is a zoned county, which sets it apart from a lot of rural Mississippi counties that have no zoning at all. That means the county Planning Department and Building Inspection division have real authority here over land use, setbacks, and construction, not just a rubber-stamp role. If you're used to the "unzoned county, do what you want" reputation Mississippi sometimes has, don't assume that applies in Lowndes.

On dwellings, the county requires a building permit for accessory dwelling units, and those ADUs need to sit on a permanent foundation and be located in a residential district. What I couldn't find anywhere on the county's own site is a clear policy on tiny homes on wheels or full-time RV living on private land. That's a real gap, not me being cagey. Where the county is silent, I'd assume the state's general caution against permanent RV occupancy applies, but you really need to call the Planning Department and ask directly before you commit to that route.

Building permits themselves are mandatory before you start any construction, full stop, per the Building Inspection department. Worth noting: Lowndes County participates in the National Flood Insurance Program, so if you're anywhere near a flood-prone area, expect extra floodplain review layered onto the standard permit.

For septic and composting toilets, you're dealing with the Mississippi State Department of Health (MSDH), not the county. Lowndes falls under MSDH's on-site wastewater program, and their environmentalists handle the soil and site evaluations that lead to a permit. Greywater reuse as its own separate category doesn't seem to have a distinct pathway; it appears folded into the same wastewater framework, so I'd treat standalone greywater irrigation systems as something to clear with MSDH first.

Rainwater harvesting looks fine, no county restriction turned up, so it inherits Mississippi's generally permissive stance.

Private wells go through the Mississippi Department of Environmental Quality (MDEQ), which requires a licensed water well contractor, and MDEQ maintains a well schedule specifically for Lowndes County. Domestic wells for personal use are generally exempt from the state's water withdrawal permitting.

On full utility disconnection, I found no county ordinance forcing a grid hookup as a condition of occupancy. The Mississippi Public Service Commission just tracks utility service areas here, it doesn't mandate you use them.

Bottom line: this is a county where zoning has teeth, so don't skip the Planning Department conversation before buying land or building anything.
