Off-Grid Living in Tensas Parish, Louisiana

I'll be upfront: Tensas Parish is Louisiana's least populated parish, and it shows in the paper trail. Digging through the parish's Municode-hosted code of ordinances, I could not find a countywide zoning ordinance or zoning map. Tensas is governed by a Police Jury, the traditional Louisiana parish structure, rather than a home-rule charter government, and police juries in small rural parishes often don't adopt formal land-use zoning at all. If any zoning exists, it would come from one of the incorporated towns (St. Joseph, Newellton, Waterproof), not the parish itself. Louisiana also has no statewide zoning statute, so absent a parish or town ordinance, unincorporated land in Tensas likely has no zoning restriction, but I'd confirm that directly with the Police Jury before assuming so.

The same gap applies to tiny homes, RVs, and alternative dwellings: no Tensas-specific rule turned up. Louisiana's State Uniform Construction Code (LSUCC), adopted by the state's LSUCC Council, sets the baseline statewide, including optional adoption of IRC Appendix Q for tiny homes, but whether that applies to your specific situation in unincorporated Tensas isn't confirmed.

Building permits themselves are handled locally: the Tensas Parish Police Jury runs a Building Permit Office in St. Joseph, so there is an active permitting function even without a visible zoning code. Because Louisiana's uniform code applies statewide, the parish can't invent its own divergent building rules, only administer the state code.

Septic systems and any on-site wastewater work route through the Louisiana Department of Health's Office of Public Health (LDH-OPH) sanitarian program, the same state authority that oversees this statewide. Composting toilets aren't separately addressed in anything Tensas-specific I found, so I'd assume they fall under the same state sanitary code until told otherwise.

Greywater reuse and rainwater harvesting both default to the state's plumbing code since no parish variance exists: greywater is permitted only as a regulated "on-site nonpotable water reuse system," while rainwater harvesting is treated more permissively and isn't lumped in with greywater rules.

Private wells are common here; the state Department of Energy and Natural Resources' Office of Conservation regulates well construction/registration, and LDH-OPH handles private well water testing requests. Tensas also has local rural water systems for anyone who'd rather hook up than dig a well.

On utility disconnection, I found no Tensas ordinance mandating hookup to water, sewer, or electric service as a condition of living somewhere. Louisiana law actually protects a resident's right to use utility services, but that's different from requiring you to use them, so this looks open, though not explicitly confirmed either way.

Bottom line: call the Police Jury before you buy or build. A lot here rests on the absence of documented rules rather than a confirmed green light.
