Off-Grid Living in Orleans Parish, Louisiana

I'll be straight with you up front: Orleans Parish is the toughest place in Louisiana to try to go off-grid, mostly because of a quirk of Louisiana government. Orleans Parish and the City of New Orleans are the same jurisdiction. There's no unincorporated parish land, no rural back-forty to quietly build on. Every acre is inside city zoning, administered by the City Planning Commission under the Comprehensive Zoning Ordinance (CZO).

Zoning. The CZO covers the entire parish, no exceptions. That's very different from rural Louisiana parishes with no zoning at all. If you're picturing raw, unzoned land to homestead on, that doesn't exist here. Any land-use question runs through the City Planning Commission.

Tiny homes and RVs. I couldn't find an official city page that lays out a specific tiny-house or "tiny home on wheels" ordinance. General practice elsewhere treats foundation-built tiny homes as regular dwellings under the state building code, and wheeled units as RVs confined to RV parks or campgrounds, but that's not confirmed for New Orleans specifically. Call the Department of Safety and Permits before you plan anything.

Building codes. Louisiana sets its building code at the state level (the Louisiana State Uniform Construction Code, built on the IRC/IBC), and the city's Department of Safety and Permits handles local permitting and inspection.

Septic and composting toilets. Statewide, on-site sewage systems are regulated by the Louisiana Department of Health. Orleans Parish has an unusual setup where the parish health officer is the city's health director, appointed by the mayor rather than the state. But practically speaking, nearly the whole parish is already on the Sewerage & Water Board's sanitary sewer system, so getting approval for an individual septic or composting system would be a rare exception, and I found no city ordinance spelling out that process.

Greywater. No New Orleans-specific greywater ordinance turned up in my research. The state plumbing code sets the baseline for on-site reuse systems, and the Sewerage & Water Board's Plumbing Department reviews any private-side plumbing work.

Rainwater harvesting. This one looks fine. No ordinance restricting rain catchment showed up, and the CZO's stormwater/site-improvement provisions (Article 21-23) address drainage broadly but don't appear to ban collecting rainwater.

Wells. Private wells fall under the state Office of Conservation in theory, but the Sewerage & Water Board actually meters and bills well water that gets discharged into the sanitary sewer. No outright ban is confirmed, but between universal water-service coverage and subsidence concerns, private wells are uncommon here and closely watched.

Full utility disconnection. State law protects your right to use utility service, but nothing I found describes a legal pathway to live inside the city with no water or sewer hookup. In fact, state law now shifts connection costs to property owners rather than waiving them, which tells you the trend is toward connection, not away from it.

Bottom line: think "urban resilience upgrades" (rain barrels, efficient plumbing, careful permitting) rather than a classic rural off-grid homestead here.
