Off-Grid Living in Greene County, Mississippi

I'll be upfront: Greene County, Mississippi is a hard place to research online. Every search I ran kept surfacing the much bigger Greene County, Missouri or Greene County, Tennessee instead. Those don't apply here, and I've excluded them. What follows is built honestly from what I could actually confirm for Greene County, MS (county seat Leakesville), plus Mississippi statewide defaults where local information simply isn't published.

Zoning. Mississippi has no statewide land-use code, and it's common for small, rural, largely unincorporated counties to skip a countywide zoning ordinance entirely. I could not find an official Greene County zoning ordinance or map, so I can't confirm one way or the other. If zoning exists at all here, it would most likely apply inside incorporated towns like Leakesville or State Line, not the unincorporated county. Call the Greene County Chancery Clerk/Board of Supervisors to check your specific parcel.

Dwellings, tiny homes, RVs. No statewide Mississippi tiny-home law exists, and I found nothing from Greene County addressing tiny homes or full-time RV living. Not confirmed either way.

Building permits. Mississippi doesn't require a statewide residential building code, so adoption is left to individual counties. I found no evidence of a Greene County building department, permit office, or code adoption online. This needs a direct call to county government.

Septic systems. This is the one area with a solid answer. The Mississippi State Department of Health (MSDH) runs the statewide on-site wastewater program, and Greene County is explicitly listed among the counties it covers. New septic systems need MSDH permitting and a site evaluation; MSDH also handles well-water sampling and complaints.

Greywater. No Greene County-specific rule turned up, so the state default applies: greywater is generally treated as wastewater needing an approved disposal system, not a separate lenient category.

Rainwater harvesting. Nothing county-specific found. Mississippi's general state-level allowance for rain barrels and cisterns should apply by default.

Private wells. No Greene County water authority page was found. Well drilling falls under state contractor licensing, and domestic wells are typically exempt from state withdrawal permitting under Mississippi's baseline rules. Confirm locally, since rural water associations sometimes have their own hookup rules.

Grid disconnection. No county ordinance found addressing off-grid power or grid-connection requirements. The general statewide caution applies: some solar/generation setups may run into utility interconnection expectations, so it's worth asking before you build a fully disconnected system.

Bottom line on my research: Greene County, Mississippi simply doesn't have much of an indexable government web presence for planning, building, or septic topics. I'd treat everything above except the septic section as "unconfirmed, ask the county directly," not as a green light.
