Off-Grid Living in Assumption Parish, Louisiana

I've been digging into what off-grid living actually looks like in Assumption Parish, Louisiana, and the short version is: this is a rural, farm-friendly parish without traditional zoning, but that doesn't mean anything goes. Here's what I found, broken down honestly by what's confirmed and what isn't.

Zoning and land use. Assumption Parish doesn't use Euclidean zoning with use-districts the way some places do. Instead, the Police Jury (the parish's governing authority) administers Chapter 26 land development regulations, which govern how land gets platted into lots, road standards, and setbacks. There's also a Chapter 19 tying the parish into the regional Louisiana Planning District Number 3. If you're eyeing raw, unplatted land to just live on, I couldn't find a rule addressing that scenario directly, since the parish's framework is built around subdivision and platting rather than a zoning map. Worth a direct call to the Police Jury before you assume anything.

Tiny homes, RVs, and dwellings. I did not find a parish-specific ordinance on tiny homes, Appendix Q, or how RVs/THOWs get classified. The parish's construction code (its Administrative Code) covers "buildings and structures" broadly and leans on the state-adopted construction code. One interesting wrinkle: the parish recognizes "family subdivisions" for large tracts (think farmland), which allow lower street standards, like aggregate-surfaced roads. That could matter for homesteaders splitting family land, but confirm specifics with the Permit Office.

Building permits. This part is clear: the Assumption Parish Permit Office issues building and occupancy permits for construction, moving structures, and mobile homes. The parish is also part of the South Central Regional Code Consortium, which coordinates code enforcement and fee schedules across member parishes.

Septic and composting toilets. Onsite wastewater is a state matter here, administered locally through the Parish Health Unit under the Louisiana Department of Health (LDH). LDH's statewide policy lets a property owner install a non-mechanical septic system for personal use, but only if they do the actual installation themselves. I found no Assumption Parish-specific composting toilet rule, so the state's plumbing/sanitary code baseline is what governs.

Greywater and rainwater. No parish-specific ordinances turned up for either. Both fall back to the Louisiana Plumbing Code baseline. Rainwater harvesting looks permitted under that same state framework, but neither has parish-level confirmation.

Wells. Much of the parish is served by Assumption Parish Waterworks District No. 1, a public water district set up by state statute. If you're outside its service area and drilling your own well, state oversight (DENR Office of Conservation and LDH) applies, since no distinct parish well ordinance exists.

Utility disconnection. I found no parish ordinance forcing individual residents to hook up to water, sewer, or electric. The one utility-related rule I found only applies to developers platting private-street subdivisions, requiring documented waste collection arrangements, not individual homeowners going off-grid.

Bottom line: the state sets most of the substantive rules here, and the parish's job is mostly permitting and platting oversight. Call before you build.
