Off-Grid Living in Livingston Parish, Louisiana

I've been digging into Livingston Parish, Louisiana for anyone thinking about building or living off-grid here, and the big headline is: this parish recently changed the rules in a way that catches a lot of people off guard. Until February 27, 2025, Livingston was one of those rural Louisiana parishes with no zoning at all. That's no longer true. As of that date, the whole parish, unincorporated areas included, is zoned under the Land Development Code (Chapter 117), administered by the Livingston Parish Planning and Zoning Commission. If you're picturing "no zoning, buy land, do whatever," check that assumption at the door and call the Planning and Zoning office first.

Keep in mind Livingston Parish also contains several incorporated towns, Livingston, Denham Springs, Walker, Albany, French Settlement, and Port Vincent, each running its own permitting through its own building department. Everything in this guide is about unincorporated parish land; if your parcel is inside town limits, that town's code controls instead.

On dwellings: standalone RV living on raw land outside a designated trailer park, mobile home park, or campsite doesn't look straightforwardly authorized based on what I found. RVs in those designated spots go through the Permit Office. Manufactured and mobile homes have their own siting standards. I did not find confirmation on tiny-home or Appendix Q minimum-size rules specific to Livingston Parish, so treat that as an open question for the Permit Office.

For actual stick-built construction, the parish enforces the statewide code (2021 IBC, IRC, IPC, IECC, IMC, plus NEC) through its own Permitting Office, since Louisiana law doesn't let parishes water down the state code. There's also a real flood-elevation rule here: the I-beam has to sit at a set height above base flood elevation, and an engineered foundation plan kicks in once a structure is elevated past a certain point, per a parish ordinance adopted in December 2024.

Septic is handled by the state, not the parish directly: applications go through the Livingston Parish Health Unit, a local office of the Louisiana Department of Health. I found nothing addressing whether a composting toilet alone can satisfy code without a permitted wastewater system, so that's a call to the Health Unit.

Greywater, rainwater harvesting, and private wells all appear to run on the state baseline here, no parish-specific rules layered on top that I could confirm. Same with utility disconnection: I didn't find a parish rule forcing hookup to public water, sewer, or electric on unincorporated land, aside from the septic requirement tied to any building permit.

Bottom line: the zoning shift is the thing to internalize, everything else largely defaults to Louisiana's state rules with the parish enforcing them.
