Coastal wind and hurricane deductibles — the percentage-of-Coverage-A trap
By Severance Calculator Editorial · Updated
The problem
Standard HO-3 deductibles in non-coastal counties run $1,000-$2,500 flat. In coastal counties from Texas through North Carolina (and inland in Florida), carriers replace the flat deductible with a percentage of Coverage A that triggers on named windstorms or hurricanes. Homeowners often see only the headline premium and miss that they have effectively self-insured the first $10,000-$25,000 of every storm. The deductible applies per occurrence — multiple storms in one season mean multiple deductibles.
The data
Florida statute §627.701 requires carriers to offer hurricane deductibles of 2%, 5%, or 10% of Coverage A. A $400,000 Coverage A policy: 2% = $8,000; 5% = $20,000; 10% = $40,000 per hurricane. Texas, North Carolina, South Carolina, and Gulf-coast Louisiana and Mississippi follow similar patterns, with the percentage often higher (3-5%) in barrier-island and immediate-coastal ZIP codes. The 2022 Hurricane Ian losses in Lee County, FL exposed thousands of homeowners to $15,000-$30,000 deductibles they had not budgeted for.
What to do
Read your declarations page for the wind/hurricane deductible line — it is separate from the all-other-perils deductible. If you are in a coastal county, calculate the dollar amount and set aside a savings buffer equal to one deductible. Ask your carrier whether buying down to a 2% deductible (vs default 5%) is cost-effective — the premium difference is often $400-$1,200/yr, which pays back in a single claim. In Florida, review the annual Office of Insurance Regulation rate filings for your carrier.
