Louisiana environmental factors
Building for Louisiana's conditions.
Louisiana home improvement is dominated by water and wind: extensive flood zones, statewide hurricane requirements, the worst Formosan termite pressure in the country, and a high water table. New Orleans layers on historic-district rules.

What shapes a Louisiana project
Substantial improvement triggers elevation requirements, sometimes lifting the house. The #1 renovation cost surprise. Get an elevation certificate first.
Hurricane straps, impact glazing, wind-rated doors required. FORTIFIED earns insurance discounts.
Pretreatment, bonds, treated framing essential. Termite damage is a frequent expensive surprise in older homes.
Raised/pier foundations common. Under-slab plumbing and drainage behave differently. Sump systems matter.
Strict architectural review; authentic materials. 1.5-3x stock cost on covered renovations.
No frost-depth footing requirement. Slab and pier foundations dominate.
