Read this before you act on anything below. This is my researched starting point for Pearl River 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 rulesPearl River County, MS

Zoning & raw-land occupancy

Unclear - verifyNo adopted countywide zoning ordinance was found on the county's official site; as of 2024 it was still a proposal being discussed by the Board of Supervisors. Confirm parcel-specific status with Pearl River County Planning & Development Division. source

Dwellings, tiny homes & RVs

Unclear - verifyNo county-specific rule on tiny homes, RV occupancy, or minimum dwelling size was found; this likely defaults to state-level county discretion. Confirm with Planning and Building before purchasing or placing a dwelling.

Building permits & codes

RestrictedThe county Building Division enforces the adopted 2018 International Building Codes family, and Planning and Development issues permits and inspections; flood-zone parcels require an elevation certificate from a surveyor. source

Septic & composting toilets

Generally allowedSeptic systems are permitted through the Mississippi State Department of Health's Division of On-Site Wastewater, which handles applications and site evaluations directly for this county rather than a local health office. source

Greywater reuse

RestrictedNo county-specific greywater ordinance exists; greywater is folded into MSDH's regulated on-site wastewater rules with no separate simplified permit path found. source

Rainwater harvesting

Generally allowedNo county ordinance restricts rainwater harvesting, so the state's general allowance for rain barrels and cisterns applies by default.

Private wells & water rights

Generally allowedNo county-specific well ordinance beyond the state's licensed-contractor requirement was found; parcels within the Pearl River County Utility Authority's service area have additional coordination rules for wells sited near septic systems.

Living disconnected from utilities

RestrictedNo county rule loosens the general state-level expectation that on-grid electric connections often continue even with solar or off-grid generation; confirm interconnection policy with your electric provider and the Building Division.
