Off-Grid Living in St. Landry Parish, Louisiana

I've been digging into St. Landry Parish, Louisiana for anyone thinking about building or living off-grid out here, and the honest answer is: this parish is looser on paper than a lot of counties I've researched, but "looser" doesn't mean "unregulated." Here's what I found.

Zoning: St. Landry Parish doesn't seem to have a comprehensive countywide zoning map covering every parcel use. What I found in the parish's Code of Ordinances (Chapter 32, hosted on Municode) mostly addresses specific overlay districts, like the I-49 Midway Corridor, and rules for utility-scale energy facilities, not general residential land-use zoning. That's good news if you're worried about a zoning board blocking off-grid living outright, but I couldn't confirm there's no restriction hiding somewhere outside those named districts, so I'd call the parish permit office before assuming anything goes. Incorporated towns inside the parish, like Opelousas, Eunice, and Sunset, run their own separate zoning through their town halls.

Dwellings, tiny homes, RVs: The parish permit office says any construction or placement of a "movable structure" in unincorporated areas (plus the towns of Arnaudville, Palmetto, and Melville) needs a permit, though movable structures skip the standard plan-review step. The parish repealed its old mobile/manufactured home ordinance in 2024 and replaced it with new "Park Planning Requirements," but I couldn't pin down current tiny-home/RV siting specifics, so confirm those directly with the permit office.

Building codes: Louisiana runs a state Uniform Construction Code (via the Louisiana State Uniform Construction Code Council), and the parish permit office defers to it. Permits are issued out of the parish office in Opelousas. If you're in a FEMA flood zone A or AE, the parish requires your lowest floor and equipment to meet base flood elevation.

Septic: This runs through the Louisiana Department of Health, not a parish septic ordinance. You contact LDH for sewer/septic permitting, and after installation an installer certification and ID tag go back to the department. Composting toilet rules specifically weren't confirmed anywhere I could find.

Greywater and rainwater harvesting: I found no parish-specific ordinances on either. It looks like St. Landry defaults to whatever the state plumbing code says, without local add-ons, but that's an inference, not a confirmed rule.

Wells: Well construction and water quality fall under state authority (Louisiana Department of Health and Office of Conservation), not the parish. The parish permit application does ask you to name your utility provider, but that looks administrative for addressing purposes.

Utility disconnection: I found no parish ordinance requiring a hookup to grid utilities or barring off-grid living. That utility-provider question on the permit form seems to be for record-keeping and inspection, not a mandatory-connection rule.

Bottom line: get the parish permit office on the phone before you buy land or start building here. A lot of the "not confirmed" gaps in this brief mean the rule genuinely may not exist, or it just hasn't been published where I could find it.
