Land — Gulf South — LA
Water rights, rainwater law, cottage food rules, right-to-farm protections, livestock zoning, and growing conditions for Louisiana landowners and buyers.
Land law varies by county, municipality, and HOA. Verify all information with your county planning department, state water agency, and a licensed attorney before any land purchase or development decision.
Water law
Civil law riparian doctrine (Napoleonic Code tradition). Landowners adjacent to waterways have use rights under the Civil Code. Groundwater largely unregulated for domestic use.
No state restrictions. Collection permitted.
Land use and production law
Louisiana Cottage Food Law: $20,000 gross annual cap; direct consumer sales; label required. Verify with Louisiana Department of Health.
Louisiana Right to Farm Act (R.S. 3:3601) protects established agricultural operations.
Parish-level zoning varies widely. Rural parishes very permissive. Suburban parishes around Baton Rouge and New Orleans have increasing restrictions.

Soil notes
Mississippi River delta alluvial soils are extremely fertile but drainage is the primary challenge. Most Louisiana soils are poorly drained; raised beds are essential in many areas.
