Coahoma County, MS
34.1827, -90.5914 · 157 ft elevationRead this before you act on anything below. This is my researched starting point for Coahoma 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 rulesCoahoma County, MS
Zoning & raw-land occupancy
Varies locallyCoahoma County is zoned countywide and the Planning office administers land use, but specific agricultural-district rules for off-grid dwellings on raw land are not confirmed from the county's own documents. Confirm your parcel's district with the Planning office. source
Dwellings, tiny homes & RVs
Unclear - verifyManufactured homes are a recognized, permitted dwelling category countywide, but no official Coahoma County page addresses tiny-house-on-wheels or full-time RV occupancy specifically. Mississippi leaves this to individual counties, and Coahoma's position isn't confirmed. source
Building permits & codes
Generally allowedThe Coahoma County Building Official issues residential, commercial, electrical, plumbing, and gas permits under an IBC/IRC-based code with state amendments, and allows homeowners to pull their own permits. A claim about farm-structure exemptions and floodplain rules could not be verified on the county's own site. source
Septic & composting toilets
Generally allowedSeptic systems, including onsite wastewater generally, are permitted through the Mississippi State Department of Health's standard statewide process, which covers Coahoma County. No additional county-specific restriction was found. source
Greywater reuse
RestrictedNo distinct Coahoma County or MSDH greywater-reuse allowance was found; greywater falls under the same statewide onsite wastewater permitting framework as septic systems. source
Rainwater harvesting
Generally allowedNo Coahoma County ordinance restricting rain barrels or cisterns was found, so Mississippi's general allowance for rainwater harvesting applies.
Private wells & water rights
Generally allowedDomestic wells are exempt from state withdrawal permitting, but drilling must be done by a contractor licensed under MDEQ's water well regulations; larger agricultural withdrawals go through the Yazoo Mississippi Delta Joint Water Management District. source
Living disconnected from utilities
RestrictedNo Coahoma County or Mississippi state page was found authorizing full disconnection from grid utilities; the state-level caution about maintaining electric service connection appears to still apply. source
