Read this before you act on anything below. This is my researched starting point for Tishomingo 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 rulesTishomingo County, MS

Zoning & raw-land occupancy

Unclear - verifyNo county zoning ordinance for unincorporated Tishomingo County was found; Mississippi's pattern is municipal zoning, and the county directs residents to the six incorporated towns. Confirm directly with the county or the relevant city if your land is near a municipal boundary. source

Dwellings, tiny homes & RVs

Unclear - verifyNo county-specific rule on tiny homes, RVs, or manufactured homes as permanent dwellings was found. This is decided at the county or municipal level in Mississippi and needs a direct call to confirm.

Building permits & codes

Unclear - verifyThe county's official departments list does not include a building or codes department, and no adoption of the International Residential Code by Tishomingo County was found. Building permitting, if it exists for your parcel, is most likely handled by the nearest municipality. source

Septic & composting toilets

Generally allowedSeptic and composting toilet systems go through the Mississippi State Department of Health's statewide onsite wastewater process, including a required soil and site evaluation before installation. No county-specific septic ordinance was found beyond this state process. source

Greywater reuse

RestrictedNo county-specific greywater rule was found, so it falls under Mississippi's Individual On-Site Wastewater Disposal Law administered by MSDH, which treats greywater as part of the wastewater system it regulates. source

Rainwater harvesting

Generally allowedNo Tishomingo County ordinance restricts rainwater harvesting, so the generally permissive Mississippi state baseline applies to residential rain barrels and cisterns.

Private wells & water rights

Generally allowedPrivate wells are permitted under the state baseline, with MSDH handling water sampling and the Mississippi Department of Environmental Quality overseeing well construction standards; no county-specific well ordinance was found. source

Living disconnected from utilities

RestrictedNo county ordinance on grid disconnection or off-grid power was found. Off-grid generation is legal under the state baseline, but full utility disconnection can be shaped by state-level interconnection rules rather than county code.
