Raising a house above the flood line is one of the most effective ways to protect a New Orleans home — and one of the most misunderstood. Here’s a clear look at how elevation works, what it involves, and why so many homeowners decide it’s worth it.
What home elevation actually is
Elevation means lifting your existing home and rebuilding its foundation higher — on piers, pilings or an elevated slab — so the living space sits above the base flood elevation (BFE) set for your area. The house itself is preserved; what changes is how high and how securely it sits.
The process, step by step
A typical elevation starts with engineering and permitting, then separating the home from its foundation, lifting it with a coordinated jacking system, building the new elevated foundation, and carefully setting the home back down. Utilities are reconnected, access (stairs and ramps) is built, and the area below is finished appropriately for flood zones.
What it costs — and grants that help
Elevation is a significant project, and cost depends on the home’s size, construction and required height. The important part many homeowners miss: grant programs have historically helped fund elevation for qualifying properties, and the long-term insurance savings change the math considerably.
The flood-insurance payoff
Flood-insurance premiums are heavily influenced by how your home sits relative to the BFE. Elevating above that line can reduce premiums dramatically — sometimes enough to offset a meaningful share of the project over time — while protecting you from the far larger cost of flood damage.
Is elevation right for your home?
Not every home or lot is an ideal candidate, but for many flood-prone properties it’s the most durable protection available. We evaluate your flood zone, base flood elevation and structure, and give you a straight answer about whether elevation makes sense for you.

Frequently asked questions
How much does it cost to elevate a house in New Orleans?
It depends on the home’s size, construction and required elevation height. We provide a detailed assessment and estimate, and help you understand grant options and insurance savings that affect the true cost.
Will elevating my home lower my flood insurance?
Usually, yes — often significantly. Premiums are tied to how your home sits relative to the base flood elevation, so raising above that line can reduce them substantially.
