Hurricane Risk in St. Augustine, FL: Storm History, Flood Zones & What It Costs to Insure
St. Augustine sits in St. Johns County, which NOAA records show under hurricane or tropical-storm conditions in 15 of the last 76 years (1950–2025), most recently 2024. 88% of sampled St. Augustine listing addresses sit outside the FEMA Special Flood Hazard Area, and 75% of homes on the market were built to the post-2002 Florida Building Code. That combination — wind exposure every few years, mostly moderate flood risk, and a young housing stock — is what an insurer prices; the sections below show each piece with its source.

">How St. Augustine homes are built
Of 43,880 St. Augustine homes with a recorded MLS sale since 2000 (public-record join; the newest-built homes are over-represented because they have all sold at least once), 75% were built in 2002 or later under the statewide Florida Building Code (post-Andrew wind standards: rated windows or shutters, strapped roofs, 130+ mph design loads in most of the county), 83% since 1995, and 7% before 1980. The median year built is 2009. Roof age and wind-mitigation features (roof-to-wall straps, secondary water barrier, opening protection) are what move a premium most; a wind-mitigation inspection costs about $100-$150 and routinely cuts premiums 15-45%.
">What hurricane risk costs: insurance in St. Johns County
Citizens Property Insurance's average St. Johns County premium is $1,378 a year across 977 policies in force (Citizens data, 2026). statewide, Citizens' 2026 rate change averaged -8.7% and private carriers filed -7% to -10%, with 17 new carriers entering the market. Every Florida policy carries a separate hurricane deductible of 2%, 5% or 10% of dwelling coverage — on a $400,000 house a 5% deductible is $20,000 out of pocket before the policy pays. Flood is a separate policy (NFIP or private); Citizens now requires it on homes valued at $400,000+ and on every policy from 2027.

">Evacuation zones and what to do before you buy
St. Johns County assigns every address an evacuation zone (A is the first to be ordered out, usually barrier islands and low-lying waterfront). Look yours up with St. Johns County Emergency Management before you make an offer; a Zone A home is not a reason to walk away, but it is a reason to price in shutters, a generator plan and a higher flood premium. Ask the seller for the wind-mitigation report and the 4-point inspection, check the roof's permit date, and get a flood elevation certificate if the home is in an AE or VE zone.
