If you've ever compared insurance quotes on two homes a block apart and gotten wildly different numbers, you're not imagining it. Florida insurers price risk down to surprisingly specific details — and a handful of factors can swing your premium by hundreds or even thousands of dollars a year.
Here's what actually drives the difference, and what to look for whether you're buying, building, or re-shopping your current policy.
1. New Construction Beats Older Homes — Often by a Lot
The single biggest factor is often simply when the home was built. Florida adopted a statewide building code in 2002 that dramatically raised construction standards, especially for wind resistance — stronger roof-to-wall connections, better-rated roofing materials, and tighter structural requirements than what came before. The code gets updated roughly every three years, so a home built in 2023 is held to a higher standard than one built in 2005.
The numbers back this up. According to Hippo Insurance's New Homes Insights Report, new construction homes in Florida carry premiums that run 42% lower than comparable existing homes — one of the largest gaps of any state in their data.
Florida law also requires carriers to factor building code compliance directly into wind mitigation pricing. Under Florida Statute 627.0629, mitigation credits must reflect features that meet Florida Building Code standards, and the state is required to reevaluate those standards every five years to keep pace with construction science.
What this means for you: if you're comparing a new build to a resale, expect the new build to come in meaningfully cheaper to insure — before any other factor is even considered.
2. Wind Mitigation Credits
This is the most underused lever homeowners have. Florida law requires insurers to offer real, mandatory discounts for specific wind-resistant features, verified through a wind mitigation inspection. The inspection checks things like:
- Roof covering and how it's rated for wind
- Roof deck attachment — how the deck is fastened to the trusses
- Roof-to-wall connection — clips and double wraps vs. just nails
- Roof shape (more on this below)
- Secondary water resistance — a sealed roof deck that keeps water out even if shingles fail
- Opening protection — impact-rated windows, doors, and code-approved shutters
A wind mitigation inspection typically costs $75–$150, and most homeowners come out ahead — savings commonly run $100 to $600 a year, and homes with strong features across the board can see considerably more. Opening protection tends to be the largest single credit, but it's all-or-nothing: if even one window or door isn't protected, you don't get the discount for that category.
The report is good for several years and is transferable — if you're buying a home, ask the seller for their current wind mitigation report before you get your own quotes.
3. Roof Shape: Hip vs. Gable
Roof geometry alone can move your windstorm premium. A hip roof slopes inward on all four sides, leaving no large, flat vertical wall section for wind to catch. A gable roof has triangular end walls, which create more surface area for wind to push against and can be more prone to uplift in a hurricane.
Citizens Property Insurance — Florida's state-backed insurer — explicitly lists hip roofs as a qualifying wind mitigation feature, alongside opening protection and reinforced roof-to-wall connections. Most private carriers follow a similar framework, though the exact discount varies by company. The direction is consistent across the board: an all-hip or mostly-hip roof is rated more favorably than a gable roof, all else equal — which is largely why newer Florida subdivisions are dominated by hip roofs. Builders are designing around the credit from the start.
4. Masonry (Block) vs. Wood Frame Construction
Construction type is one of the first things an insurer asks about, and it's a bigger factor than most buyers expect. Concrete block (often called CBS — concrete block stucco) construction is generally cheaper to insure than wood frame for a few compounding reasons: it doesn't burn, it doesn't attract termites, and it holds up better structurally over time.
According to First Coast House Plans, a Jacksonville-based design firm, concrete block homes often qualify for "superior construction" discounts that can save homeowners 15–30% annually compared to a wood frame home without additional mitigation features. Modern wood frame construction built to current code with hurricane straps, reinforced decking, and impact windows can close some of that gap — but typically not all of it.
One technical note if you're buying a home with mixed construction: most insurers require masonry to make up at least two-thirds of the structure for the home to be rated as masonry. Fall short of that, and the whole home gets rated as frame construction, regardless of how much block is used.
Putting It Together
None of these factors work in isolation — they stack. A new-construction, hip-roofed, concrete block home with full opening protection is about as cheap as Florida property insurance gets. An older, gable-roofed, wood frame home with original single-pane windows sits at the other end of the spectrum, even in the same neighborhood.
If you're buying, ask for the current wind mitigation report and find out the construction type before you fall in love with a house — it changes the insurance math more than people expect. If you already own your home, a wind mitigation inspection is one of the few times spending $100–150 has a real shot at paying for itself in the first year.
