Off-Grid Living in Humphreys County, Mississippi

Humphreys County is one of those small Mississippi Delta counties where I couldn't find a published, indexed zoning or building code online, and there's no Municode/eCode360 page for it either. That's not unusual for rural counties with low populations, but it does mean a lot of what would normally be a clean county ordinance answer here is genuinely "not confirmed" and I want to be upfront about that rather than guess at numbers that don't exist.

Zoning and land use. I could not locate an official Humphreys County zoning ordinance or map. It looks like the county largely defers to state-level code enforcement (via the Mississippi State Fire Marshal's Office) for construction outside the towns of Belzoni, Isola, Louise, and Silver City, rather than running its own planning department. If you're eyeing unincorporated land, call the Board of Supervisors directly to ask what, if anything, governs your parcel.

Dwellings, tiny homes, RVs. No county-specific rule found. Mississippi has no statewide tiny-home law, so this is an open question here, confirm directly with the county or the relevant town hall if you're inside Belzoni, Isola, Louise, or Silver City.

Building permits. Outside the towns, permitting appears to reference state building codes as applied by the State Fire Marshal, but I found no ordinance formally adopting the IRC or IBC at the county level. Inside the four municipalities, each town handles its own permitting separately.

Septic and composting toilets. This one is solid: septic systems statewide, including in Humphreys County, are regulated by the Mississippi State Department of Health (MSDH) under Title 41, Chapter 67 of the Mississippi Code. Humphreys County is served by MSDH's regional program, and you apply directly to MSDH (online or by paper form) rather than through the county. Composting toilets and alternative systems fall under this same MSDH review, no separate county rule exists.

Greywater. No Humphreys-specific greywater ordinance exists; it's folded into the same MSDH onsite wastewater rules as septic, so treat greywater disposal as regulated, not something you can just release freely.

Rainwater harvesting. I found nothing restricting this at the county or state level, so I'm treating it as permitted by default, but there's no dedicated county page confirming best practices either.

Private wells. No county well ordinance was found. Domestic wells are generally exempt from state withdrawal permits, but drilling still requires a licensed well contractor under state rules. A commercial listing mentioned town halls issuing "water system permits," but I couldn't verify that against an official page, so treat it as a "confirm locally" item.

Off-grid utilities. No explicit Humphreys County rule bans disconnecting from the grid. Any requirement would most likely surface through occupancy permitting tied to state building code enforcement, but nothing specific was found targeting solar-only or fully off-grid homes.

Bottom line: for anything beyond septic (which is clearly MSDH's jurisdiction), your best move is a direct call to the Board of Supervisors or, if you're within town limits, the relevant city hall.
