What drives the risk for expensive homes in Louisiana
- Catastrophe exposureLouisiana's dominant exposures are hurricanes and tropical storms with storm surge, and heavy-rain and river flooding. The state hazard plan also covers tornadoes, hail, high wind, subsidence and coastal erosion. Source
- Wind and hurricane deductiblesFor owner-occupied 1-2 family home policies issued or renewed since 2010, any separate named-storm or hurricane deductible applies once per calendar year (La. R.S. 22:1337). For later storms in the same year, the insurer may apply only the unused balance of that deductible or the all-other-perils deductible, whichever is greater. The Department of Insurance explains how this works in Advisory Letter 2018-01, reissued in 2023. Source
- FloodFlood is excluded from homeowners policies and NFIP caps building coverage at $250,000. For most expensive Louisiana homes, especially in greater New Orleans, the Northshore and coastal parishes, private excess flood coverage above the NFIP limit is a common need. Source

When the standard market says no, and what earns credits
- Insurer of last resort and wind poolsLouisiana Citizens Property Insurance Corporation is the state's insurer of last resort. It writes through a statewide FAIR Plan and a Coastal Plan for designated coastal areas with higher hurricane exposure, and it is open to owners who have been declined by an authorized insurer. Source
- Mitigation credits and programsThe Louisiana Fortify Homes Program gives grants of up to $10,000 toward re-roofing to the IBHS FORTIFIED Roof standard for homesteaded homes in eligible parishes, chosen by lottery in funded rounds. Separately, La. R.S. 22:1483 requires admitted insurers to give an actuarially justified wind-premium discount for FORTIFIED-designated homes. Source
Worth knowing in Louisiana
Louisiana requires admitted insurers writing wind coverage to give a discount for homes with an IBHS FORTIFIED Roof designation, and the state helps pay for those roofs through Fortify Homes grants. For an expensive coastal home, a FORTIFIED roof can affect both premium and insurability. Source

Common questions
Do Louisiana homeowners policies have a separate wind or hurricane deductible?
For owner-occupied 1-2 family home policies issued or renewed since 2010, any separate named-storm or hurricane deductible applies once per calendar year (La. R.S. 22:1337). For later storms in the same year, the insurer may apply only the unused balance of that deductible or the all-other-perils deductible, whichever is greater. The Department of Insurance explains how this works in Advisory Letter 2018-01, reissued in 2023.
Where can an expensive home in Louisiana get coverage if insurers decline it?
Louisiana Citizens Property Insurance Corporation is the state's insurer of last resort. It writes through a statewide FAIR Plan and a Coastal Plan for designated coastal areas with higher hurricane exposure, and it is open to owners who have been declined by an authorized insurer.
Is flood insurance enough for a high-value home in Louisiana?
Flood is excluded from homeowners policies and NFIP caps building coverage at $250,000. For most expensive Louisiana homes, especially in greater New Orleans, the Northshore and coastal parishes, private excess flood coverage above the NFIP limit is a common need.
