Off-Grid Living in Chickasaw County, Mississippi

Chickasaw County, Mississippi is one of those rural places where the paper trail runs thin, and I want to be upfront about that rather than paper over it with guesses. I could not find an official Chickasaw County zoning ordinance, building code, or planning department page anywhere online. That doesn't mean rules don't exist, it means I couldn't confirm them from an official source, and you should treat "unconfirmed" as a real answer, not an oversight on my part.

Zoning and raw land. Mississippi law lets counties and municipalities adopt comprehensive plans and zoning, but it's optional (Miss. Code Title 17, per Justia's hosting of the statute). I found no evidence Chickasaw County itself has adopted a countywide zoning ordinance. The county contains four towns, Houston, Okolona, New Houlka, and Woodland, and it looks like zoning and building permits are handled inside those town limits rather than county-wide. If your land is outside all four towns, you may be in a genuinely unzoned pocket, but confirm that with the Chancery Clerk's office before you assume anything.

Dwellings, tiny homes, RVs, and building permits. Same story: no county ordinance found. Mississippi has no mandatory statewide residential building code, so unincorporated land in Chickasaw County may not require a building permit at all, but incorporated towns like Houston likely run their own permitting. I'd call ahead rather than guess.

Septic and wells. This is the one area with a clear state hand on it. The Mississippi State Department of Health (MSDH) administers on-site wastewater (septic) permitting statewide, and Chickasaw County is explicitly listed in MSDH's coverage area. New septic systems need a permit and a site/soil evaluation through MSDH, and this is the same office that also handles private well water sampling in the region. Composting toilets aren't separately addressed, so I'd assume MSDH's standard wastewater rules apply.

Greywater. Mississippi has no separate greywater framework at the state level, so greywater is legally treated like sewage, meaning it needs to go through an MSDH-approved wastewater system. No Chickasaw County-specific exception was found.

Rainwater harvesting. No county restriction found, and Mississippi's state baseline is permissive: residential-scale rainwater collection doesn't require a permit.

Utilities. Off-grid power generation is legal under the state baseline, but full disconnection from grid services can run into utility interconnection rules depending on your provider. No Chickasaw County ordinance was found addressing this either way.

Bottom line: for septic and wells, MSDH is your authority and that part is solid. For zoning, building, and dwelling type, Chickasaw County itself is a blank page in the official record, so your real answers will come from a phone call to the Chancery Clerk or the relevant town hall if you're near Houston, Okolona, New Houlka, or Woodland.
