Florida homeowners insurance is the line item that surprises Northeast buyers most. The good news is that the home you choose affects it more than almost anything else.

In general, newer homes cost less to insure than older ones in Florida. Here’s why, and how to make sure you capture the savings.

The Main Reason: The 2002 Building Code

Florida’s building code was strengthened significantly after Hurricane Andrew. Homes permitted on or after March 1, 2002 were built under the 2001 Florida Building Code, which requires:

  • Stronger roof coverings
  • Better roof-deck attachment
  • Reinforced roof-to-wall connections

According to Florida Department of Financial Services guidance, homes built to the 2001 code or later qualify for a minimum 68% discount on the windstorm portion of the premium. Citizens Property Insurance also gives a built-in discount for homes built in 2002 or later.

That discount applies to the wind portion of your premium, not the whole bill, and the actual dollar savings depend on your carrier and home.

The Five Features That Earn Credits

Florida law (Statute 627.0629) requires insurers to give credits for documented hurricane-resistant features. The ones that move the needle most:

  • Hip roof shape, which resists wind better than a gable roof
  • Roof-to-wall connections such as hurricane straps or clips
  • Ring-shank nails on the roof deck
  • A secondary water barrier, usually a peel-and-stick membrane under the roof covering
  • Opening protection, such as impact windows, shutters, or impact-rated doors

Most St. Johns County new construction has several of these built in.

Roof Age: The Other Big Factor

  • Carriers often decline or surcharge asphalt shingle roofs older than about 15 years
  • Insurers can’t non-renew a policy solely because of roof age under 15 years (Florida Statute 627.7011)
  • A brand-new roof resets your age rating from day one
  • Older homes with a new roof permitted under modern code can earn some of the same credits, but the house itself still ages

For a buyer, a new-build roof removes one of the biggest sources of premium surcharges and underwriting trouble.

What the Savings Can Look Like

No honest source offers one statewide number, since the amount varies by carrier, home, and documentation. Industry estimates:

  • A favorable wind mitigation report can cut the wind portion of the premium by roughly 20% to 50%
  • That is often worth $500 to $2,000 or more per year
  • A homebuilt after 2002 with a hip roof, secondary water barrier, and impact windows or shutters can cut premiums by a further 20% to 40%, according to one local guide
  • A new roof alone is often estimated to lower premiums by 10% to 30%

These are broad ranges. Get actual quotes before assuming a number.

How to Capture the Savings

1. Ask the builder for the documentation. Request the permit date, roof specs, and any wind mitigation documentation.

2. Order a wind mitigation inspection. It’s performed on the state’s OIR-B1-1802 form (a revised form took effect April 1, 2026). Cost is typically $75 to $150.

3. Send the report to your insurer. Credits are not automatic. Your carrier must receive the form.

4. Renew the inspection every five years. After five years, carriers aren’t required to keep applying the credits.

5. Shop multiple carriers. An independent broker can compare admitted carriers and find the best fit.

6. Set the right dwelling limit. It should reflect rebuild cost, not purchase price.

Where Newer Isn’t Automatically Cheaper

  • Flood zone: a new home in a high-risk zone can still need flood insurance. Check the specific lot.
  • Coastal location: homes near the ocean cost more to insure regardless of age.
  • Purchase price and CDD: new construction often costs more upfront and may carry a CDD assessment, so compare total cost, not just insurance.
  • Pre-2002 communities: older sections of St. Johns County may need updated roofs or documentation to earn credits.

The Market Backdrop

Florida’s insurance market has begun to stabilize. Citizens Property Insurance reduced its homeowner rates by about 8.8% effective July 1, 2026, its first decrease in years, and several private carriers have filed lower rates. Premiums are still higher than in the Northeast, so the advantage of a newer home matters.

The Bottom Line

A newer home in St. Johns County usually costs less to insure because of the 2002 building code, modern roof construction, and documented wind features. To get the savings, you need to document the features, send the inspection to your carrier, and compare quotes. Confirm flood zone and coastal exposure before you assume a low premium.
