Updated October 17, 2026. Louisiana homeowners preparing for a 2027 insurance renewal should ask for the FORTIFIED discount calculation in writing. The state’s benchmark percentages apply to the hurricane portion of the premium. A 29% hurricane-premium discount can produce a much smaller percentage reduction in the total annual bill.
The following tables explain the published benchmarks and show how the hurricane portion of a premium affects the total savings. A printable worksheet helps you compare quotes and request a written calculation from your insurer.
What takes effect, and when
LDI’s revised April 29, 2026 Bulletin 2026-04 directs insurers to implement the required discounts no later than January 1, 2027, for new or renewed residential property policies issued on or after that date. That is a policy-issuance and renewal trigger; it does not say every existing policy receives a midterm refund on January 1.
The final Regulation 136 was published September 20, 2026, and became effective upon final publication. Section 20903 applies it to admitted insurers authorized to write property and casualty coverage in Louisiana. Section 20907 addresses qualifying residential property with an IBHS FORTIFIED designation. Ask the agent to identify the actual insurer and confirm its admitted status, especially if the paperwork involves a surplus-lines placement.
Sections 20909–20915 connect the discount to LDI’s published benchmarks and require commissioner approval of the discounts. An insurer seeking a lower rate must request permission and supply actuarial justification; higher discounts must also be actuarially justified. If the quoted percentage differs, request the applicable approved schedule or deviation and its effective date. This guide addresses the residential benchmark program, rather than calculating commercial-property credits.
The published hurricane-premium benchmarks
Scroll horizontally to see all columns. Use the arrow keys when the table is focused.
| LDI zone | FORTIFIED Roof | FORTIFIED Silver | FORTIFIED Gold |
|---|---|---|---|
| North | 16% | 20% | 24% |
| Central | 27% | 35% | 42% |
| South | 29% | 43% | 49% |
Source: LDI’s benchmark table and official zone map. Match both the property’s zone and the designation shown on its certificate. Roof, Silver and Gold are alternative designation columns; adding the percentages together is not the calculation shown by the table.
The state explains that the benchmarks use modeled hurricane losses for representative homes, adjusted for expenses. They are benchmarks for premium calculation, not a prediction of what one house will save or how much damage it will avoid. Ask the insurer to confirm the address’s zone; do not substitute a grant-eligibility map or a broad description such as “south Louisiana.”
Why a 29% discount may cut the total bill by 5.8%
The following examples are hypothetical. Each starts with a $5,000 annual premium before the illustrated credit and assumes a South-zone FORTIFIED Roof discount of 29%, with all other pricing and coverage unchanged. The difference is how much of that premium is attributable to hurricane risk.
Scroll horizontally to see all columns. Use the arrow keys when the table is focused.
| Illustration | Hurricane component before credit | Other premium | Illustrated credit | Total after credit |
|---|---|---|---|---|
| A: larger hurricane share | $3,000 | $2,000 | $870 | $4,130 |
| B: smaller hurricane share | $1,000 | $4,000 | $290 | $4,710 |
In A, $3,000 × 0.29 = $870, which is 17.4% of the original $5,000 total. In B, $1,000 × 0.29 = $290, or 5.8% of the same total. Applying 29% to the full $5,000 would incorrectly suggest $1,450 in savings in both cases.
A renewal can also include changed rates or coverage amounts. Suppose last year’s bill was $5,000, while this year’s otherwise identical pre-credit quote is $6,000, including $3,600 in hurricane premium. The illustrated 29% credit is $1,044, producing $4,956. The year-over-year bill falls only $44 even though the credit is $1,044. This is why last year’s bill alone cannot establish whether the new credit was applied.
Use the insurer’s actual rating explanation. A displayed hurricane component may already include credits, and multiple discounts may interact. Do not subtract a FORTIFIED credit twice or assume every fee is reduced by the same percentage.
North Louisiana roofs: what the 16% benchmark means
On October 15, 2026, FHLB Dallas reported that a $129,442 grant through Bonvenu Bank helped eight Shreveport and Bossier City families obtain FORTIFIED-designated roofs. That funding answers how the improvements were paid for. A homeowner must separately confirm the designation and the insurance credit.
LDI’s published North-zone benchmarks are 16% for Roof, 20% for Silver, and 24% for Gold, applied to the hurricane portion of the premium, with implementation directed no later than January 1, 2027. Confirm the property’s zone and the insurer’s applicable approved schedule. These figures should not be applied to the entire homeowners bill.
A hypothetical North-zone Roof example: Assume a $2,400 annual premium before the illustrated credit includes a $400 hurricane component, and the applicable Roof discount is 16%. The credit would be $400 × 0.16 = $64. Holding everything else constant, the resulting premium would be $2,336. Applying 16% to the whole $2,400 would incorrectly suggest a $384 credit. The example does not estimate any of the eight families’ actual premiums or savings.
- Obtain the current IBHS designation certificate, including the property address, level, and expiration date.
- Ask the insurer to confirm the designation qualifies under its approved schedule and identify the property’s LDI zone.
- Request the hurricane-premium component, percentage, and dollar credit in writing, including whether the quoted premium already includes the discount.
- Compare total premiums using the same coverage limits and deductibles, and keep grant records separate from the insurance calculation.
The FHLB Dallas FORTIFIED Fund is separate from Louisiana’s state Fortify Homes Program. The bank’s October announcement says its 2026 homeowner allocation had been exhausted as of July 1; the completed-project announcement should not be read as an invitation to apply for available funds. Confirm any later funding round directly with the program.
Keep the designation, grant award, contractor invoices, and insurer’s response together. That file helps resolve whether a missing credit results from missing documentation, the policy’s rating treatment, or another issue. The contractor verification guide addresses the separate licensing and insurance checks for the company doing the roof work.
A worksheet for comparing renewal quotes
Download the two-page FORTIFIED renewal comparison worksheet (PDF). It includes the benchmark table, an arithmetic example and room to record two competing quotes. You can also use the fields below in an email to your agent.
Scroll horizontally to see all columns. Use the arrow keys when the table is focused.
| Record or question | What to enter or request |
|---|---|
| Property and policy | Street address, insurer’s legal name, admitted status, policy term and quote date. |
| Designation | Certificate number, Roof/Silver/Gold level, issue date and current expiration date. |
| Zone and discount | Insurer-confirmed LDI zone; applicable percentage; approved schedule or deviation if different. |
| Calculation | Hurricane premium before this credit, dollar credit and whether the displayed premium already includes it. |
| Comparable coverage | Dwelling limit, replacement-cost terms, hurricane and other deductibles, exclusions and endorsements. |
| Total cost | Annual policy premium, separate fees and installment charges, and any separate policy being compared. |
| Follow-up | Who answered, date, written explanation, missing documents and promised correction date. |
For competing quotes, ask each agent to price the same coverage and deductible choices. A lower premium with a larger hurricane deductible or reduced coverage is a different bargain. Record those changes before deciding which offer is cheaper. Keep any separate flood-policy cost on its own line so that it does not enter this hurricane-credit calculation.
Confirm the certificate before relying on a projected discount
IBHS’s renewal guidance describes five-year designation periods and a renewal inspection by a certified evaluator. It also says some certificates expiring during 2024–2027 received adjusted expiration dates. Obtain the current certificate rather than assuming the date on an old copy is still controlling, and send it to the insurer.
Before signing a roofing contract, ask who will arrange the evaluation, what documentation will be delivered, and how the property will obtain its designation. For an already completed project, reconcile the property address and level on the certificate with the insurer’s record. Keep the certificate, evaluation correspondence, invoices and written insurance response together. An invoice using the word “FORTIFIED” is a reason to request the certificate, not a substitute for checking it.
Historic homes: coordinate the roof, permits and insurance
A historic home may require several separate approvals. New Orleans’ HDLC Express Lane guidance expressly includes roof replacement, including FORTIFIED roofing, among projects that may use that review route. It still requires a complete application and supporting materials. Confirm the property’s applicable historic-district review and roofing permits before work starts; an insurance quote does not approve a construction design.
Keep four files or checklist lines: construction scope, historic/building approvals, IBHS designation, and insurance calculation. Add grant paperwork as a separate funding item if applicable. A grant award does not establish the premium savings, and a projected discount does not establish grant eligibility. Check the program’s current application dates before making plans that depend on a grant.
For budgeting, compare the extra project cost with an actual written insurance estimate. If the extra out-of-pocket cost were $4,000 and the annual credit were $290, a simple division would produce about 13.8 years; at $870 it would be about 4.6 years. Those illustrations ignore financing, future premiums, maintenance and the protective value of the improvements. They are not investment-return forecasts.
Ask for a written calculation
You can send this request with the current designation certificate: “Please confirm my property’s FORTIFIED level and LDI zone, the applicable discount percentage, and the hurricane-premium amount used to calculate it. Please show the dollar credit and confirm whether it is already included in this renewal quote. If your percentage differs from the published benchmark, identify the approved schedule or deviation. Please also identify changes in coverage, deductibles, fees or other credits that affect the total.”
If the response is incomplete, ask the insurer to identify the missing document or disputed input. Keep the quote and your submission confirmation. LDI’s consumer complaint guidance includes premium-rate and refund concerns and explains the online and paper complaint routes. The department lists 1-800-259-5300 for assistance. Present the calculation and written responses so the reviewer can see the precise issue.
Authorities and policy-specific questions
The rules discussed here come from final Regulation 136, revised Bulletin 2026-04 and LDI’s published benchmark table, available October 17, 2026. The certificate and historic-review sections refer to IBHS and New Orleans guidance. The numerical examples are hypothetical and assume the stated premium components.
For an individual policy, confirm the current approved rate schedule, the home’s designation and zone, and the insurer’s calculation. Those documents determine the applicable credit and provide the starting point for resolving a disputed renewal premium.
