Raising a house in Louisiana typically costs $20,000 to $80,000 or more. The lift alone runs about $12,000–$28,000 for a pier and beam home and $15,000–$40,000 for a slab home. Flood-insured, substantially damaged homes can get up to $30,000 from Increased Cost of Compliance, and FEMA mitigation grants can cover 75% or more.
Foundation Repair Baton Rouge talks through house raising with homeowners in Central, Denham Springs, Gonzales and other places the 2016 flood hit hardest. In Louisiana this work is often called shoring. Here’s what it costs and how people pay for it.

What drives the price
- Foundation type. Slab lifts cost more and involve more engineering.
- Height. Every additional foot of elevation adds foundation, stairs and bracing.
- House size and shape. Additions, L-shapes and brick veneer complicate a lift.
- Utilities. Plumbing, electrical, gas and HVAC must be disconnected, extended and reconnected.
- Access and permits. Engineering, permits and elevation certificates are part of the total.
- Finishing. Stairs, landings, skirting and ADA access can be a big share of the bill.
How homeowners pay for it
Increased Cost of Compliance (ICC). If your NFIP-insured home is declared substantially damaged by a flood, ICC can pay up to $30,000 toward elevation, on top of the building claim. FEMA Flood Mitigation Assistance. Applications go through your parish, not directly to FEMA; the federal share is typically 75%, rising to 90% for repetitive-loss and up to 100% for severe repetitive-loss properties. Ask your parish floodplain manager what programs are open. See does flood insurance cover foundation damage.
Raise, or repair in place?
If your home has flooded and sits below current base flood elevation, raising it deals with both the foundation and the flood risk, and can lower flood insurance premiums. If it has never flooded and sits at or above flood elevation, repairing in place with slab foundation repair or pier and beam repair is far cheaper. We’ll give you both numbers.
Bottom line
Most Louisiana house raising projects cost $20,000–$80,000, with ICC and FEMA mitigation funds covering a large share for eligible homes. For an honest comparison of raising versus repairing, call Foundation Repair Baton Rouge.
