Montgomery County, MS
33.6447, -89.7265 · 253 ft elevationRead this before you act on anything below. This is my researched starting point for Montgomery County, MS, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.
The local rulesMontgomery County, MS
Zoning & raw-land occupancy
Unclear - verifyI couldn't find a published countywide zoning ordinance or planning department for Montgomery County, MS. Many small rural Mississippi counties don't adopt zoning at all, but I couldn't confirm that one way or the other, so call the Board of Supervisors before you buy or build. source
Dwellings, tiny homes & RVs
Unclear - verifyThere's no county-level ordinance I could find addressing tiny homes, RVs, or manufactured homes as permanent residences. Winona and Duck Hill may have their own municipal rules if you're inside those town limits, so this needs a direct check with the county or the relevant town.
Building permits & codes
Unclear - verifyI found no evidence Montgomery County has adopted a residential building code or runs a permit office for unincorporated land, and Mississippi has no mandatory statewide residential code either. That said, I couldn't confirm this is actually the case, so ask the Board of Supervisors directly before assuming no permit is needed. source
Septic & composting toilets
Generally allowedMontgomery County is one of the counties served by the Mississippi State Department of Health's on-site wastewater program, so a septic system needs an MSDH-administered permit and site/soil evaluation through the county health office. I didn't find any separate county septic ordinance beyond that state program. source
Greywater reuse
RestrictedThere's no separate greywater rule for Montgomery County that I could find, so it falls under the same MSDH on-site wastewater permitting umbrella as septic, meaning informal greywater setups likely aren't recognized outside an approved system. Check with MSDH's on-site wastewater office for specifics. source
Rainwater harvesting
Generally allowedI found nothing from the county restricting rainwater collection, so this follows the general Mississippi baseline where rain barrels and cisterns are legal without a permit.
Private wells & water rights
Generally allowedPrivate wells in Montgomery County are handled through state-level licensing and drilling regulations rather than a distinct county water authority, and MSDH staff also handle well-water sampling here. No separate county well ordinance turned up in my research. source
Living disconnected from utilities
Unclear - verifyNo Montgomery County ordinance on grid disconnection or off-grid power turned up, so this defaults to the general Mississippi picture where generating your own power is fine but a guaranteed right to fully disconnect from utilities isn't clearly established. Worth confirming with the Board of Supervisors if full disconnection matters to your plans.
