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

Zoning & raw-land occupancy
Unclear - verifyI couldn't find a published countywide zoning ordinance for unincorporated Pike County. Zoning in Mississippi is set at the county or municipal level, and cities like McComb run their own zoning departments separately from the county, so if you're outside city limits you'll want to call the Pike County Board of Supervisors directly to find out what, if anything, governs your parcel. source
Dwellings, tiny homes & RVs
Unclear - verifyNo county-specific rule on tiny homes, tiny homes on wheels, or full-time RV living turned up in my research for Pike County. Mississippi has no statewide tiny-home law, so this gets decided locally, and inside McComb city limits you'd deal with their Zoning, Inspections & Permits department, while unincorporated land needs a direct call to the county. source
Building permits & codes
Varies locallyMississippi doesn't mandate a statewide residential building code, so code adoption is a local decision. McComb has an active permitting and inspection department for construction within city limits, but I found no equivalent published building-permit rule for unincorporated Pike County, so confirm directly with the county whether a permit is required outside town. source
Septic & composting toilets
Generally allowedSeptic systems and composting toilets fall under the Mississippi State Department of Health's statewide On-Site Wastewater program, not a separate Pike County ordinance. You'd go through the local county health department/environmentalist office for a soil and site evaluation and permit, same as anywhere else in the state. source
Greywater reuse
RestrictedThere's no distinct greywater ordinance for Pike County that I could find, and Mississippi doesn't have a separate statewide greywater framework either, so greywater reuse gets folded into the same MSDH onsite-wastewater permitting rules as septic. source
Rainwater harvesting
Generally allowedNo Pike County ordinance restricting rain barrels or cisterns turned up in my research, so this defers to the general state-level allowance for rainwater harvesting in Mississippi.
Private wells & water rights
Generally allowedPrivate wells fall under Mississippi Department of Environmental Quality standards statewide, and MSDH environmentalists handle site evaluations and water sampling tied to well and septic permitting. No Pike County-specific well ordinance was found, so the state baseline applies: domestic wells are generally exempt from withdrawal permits but must be drilled by a licensed contractor. source
Living disconnected from utilities
RestrictedI found no Pike County ordinance that either requires or waives a grid hookup. This defers to the state-level position that off-grid power generation is legal, but going fully disconnected can still run into requirements from whichever authority, state or municipal, has jurisdiction over your property.
