Off-Grid Living in Wilkinson County, Mississippi

I'll be upfront: Wilkinson County, Mississippi doesn't have much of an official online paper trail. I went looking for a county zoning ordinance, a building code adoption page, and any dedicated environmental health rules specific to the county, and I came up mostly empty on the county's own site. Here's what I can tell you honestly, and where the gaps are.

Zoning. Wilkinson County itself doesn't appear to run a unified countywide planning and zoning department. Instead, zoning verification happens at the municipal level, in whichever of the county's cities (Woodville, Centreville, or Crosby) a property sits in. If you're in unincorporated county land, this may mean there's no formal zoning code at all, which is common in rural Mississippi counties, but I couldn't confirm that one way or the other for Wilkinson specifically. Call the municipality nearest your parcel, or the county government, before assuming anything.

Dwellings, tiny homes, RVs. No county-specific rule turned up. Mississippi has no statewide tiny-home law, so this falls to local rules, which for Wilkinson County I simply couldn't locate. Most Mississippi counties that do regulate this restrict full-time RV living, so don't assume you're clear.

Building permits. Same story. No official county building department page or code adoption ordinance found. Mississippi has no mandatory statewide residential building code, meaning each county or city decides for itself whether to require one. Some third-party permit directories mention multiple "jurisdictions" tied to Wilkinson County, hinting permitting may be split among the county and its towns, but I couldn't verify that against an official source.

Septic. This one is solid: septic systems statewide, including here, are administered by the Mississippi State Department of Health (MSDH), not the county. You can't self-permit; a Licensed Professional Evaluator has to do the soil evaluation and a Licensed Installer has to build the system. The county health office implements these state rules locally, but the regulations themselves come from MSDH.

Greywater. No local exception exists, so it inherits the state default, which effectively treats greywater like septic waste, requiring an approved disposal system rather than a permissive reuse rule.

Rainwater. Legal statewide with no permit needed for small-scale rain barrels or cisterns, and I found nothing from the county that changes this.

Wells. Drilling is a state, not county, function, done by a licensed contractor. Domestic wells are exempt from state withdrawal permits. Wilkinson County does have its own Soil and Water Conservation District, but that's for conservation incentives, not well permitting.

Off-grid utilities. Off-grid solar and generation are legal, but full grid disconnection can run into state-level utility rules. No Wilkinson County ordinance on this was found.

Bottom line: for anything touching zoning, dwellings, or building codes, you're going to need to call around, because the official record just isn't published where I can verify it.
