Off-Grid Living in Iberville Parish, Louisiana

I've been digging into what off-grid living actually looks like in Iberville Parish, Louisiana, and the first thing worth knowing is that this parish is a bit unusual for rural Louisiana: it actually has a countywide land-use framework. Most rural Louisiana parishes have no zoning at all, but Iberville adopted a Unified Development Code back in 2000 and has Subdivision Regulations dating to 1981, both administered by the Iberville Parish Planning Commission. That said, several incorporated towns inside the parish, like Plaquemine, St. Gabriel, White Castle, Maringouin, and Grosse Tete, run their own permitting separately within their town limits. So the first question I'd ask myself before doing anything is: am I inside a town, or in the unincorporated parish?

On the building side, the Iberville Parish Permits & Inspections Department handles new construction, plumbing, electrical, mechanical, demolition, solar, and mobile home permits, and it follows the International Building Codes as adopted by the state. All applications go through an online portal now. If you're building anything other than a single-family home, the Louisiana State Fire Marshal also has to sign off on plans before construction starts, which is a state-level requirement layered on top of the parish process.

Septic is where things get more restrictive. Onsite wastewater systems statewide are licensed and permitted through the Louisiana Department of Health's Bureau of Sanitarian Services, with a sanitarian working out of the parish Health Unit as your local contact. There is a narrow allowance for owner-installed non-mechanical septic systems for personal use, but hiring an unlicensed installer for any part of the job isn't allowed. I found nothing on composting toilets specifically at the parish or state level, so I'd call the Health Unit directly if that's your plan.

Greywater and rainwater harvesting don't appear to have any Iberville-specific rules on the books; both would fall back to whatever the state plumbing code says about nonpotable water reuse and storm drainage, with no local add-ons that I could confirm.

Wells are an interesting case here. Iberville sits outside the Capital Area Groundwater Conservation District, which covers East and West Baton Rouge, East and West Feliciana, and Pointe Coupee. That means the special regional well-permitting authority those parishes use doesn't apply in Iberville, and wells here fall under the general state well-construction framework, with small domestic wells typically exempt from stricter registration requirements anyway.

As for cutting ties to utilities altogether, I didn't find a parish ordinance forcing hookup, though the parish Utility Department does charge tie-in fees for anyone who chooses to connect. Whether a specific town or subdivision covenant mandates hookup is something I'd confirm town by town.
