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.
House raising costs by scope
| Scope | Typical range |
|---|---|
| Lift only — pier and beam | $12,000–$28,000 |
| Lift only — slab | $15,000–$40,000 |
| Lift + partial services (foundation, utilities) | $40,000–$80,000 |
| Complete turnkey with new foundation | $80,000–$150,000+ |
| Per square foot (varies with scope) | $10–$90 |

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 in a high-risk flood area and your community finds it substantially damaged (repairs of 50% or more of its pre-damage market value) or repetitively flooded (twice in 10 years, with repairs averaging at least 25% of value each time), ICC can pay up to $30,000 toward elevation, on top of the building claim (FEMA, updated Jan. 12, 2026). 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.
If you live in Livingston Parish, the Comite Diversion Canal could change your flood zone, and FEMA map revisions will not come before late 2027 at the earliest, so compare both numbers before you commit to a lift.
What Baton Rouge’s elevation rule means for the target height
In East Baton Rouge Parish, new development and substantial improvements must have the lowest floor at least one foot above the highest of several reference elevations, including FEMA’s Base Flood Elevation, the Community Defined Flood Elevation and the Record Inundation (City-Parish QuickFacts: Flood Hazard Areas). That one-foot margin is why an elevation certificate comes before a quote: the lift height, and so the cost, follows from it. Ask the parish floodplain office which reference elevations apply to your address.
Slab homes are the hard case
FEMA’s retrofitting guide (P-312) says slab-on-grade houses “present special difficulties and require a different lifting technique.” The slab is usually 4 to 6 inches thick, its wire mesh is not intended to provide structural strength, and the work “should be performed only by a highly skilled contractor with extensive experience in lifting slab-on-grade houses.” That is the main reason slab lifts cost more than pier and beam lifts in the table above. Ask any contractor for slab-lift references, and check the license: see Louisiana foundation contractor license rules.
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.
