New construction home insurance Florida buyers ask us about almost always costs less to insure than an older home of the same size and value, and yes, a brand-new house typically qualifies for the strongest wind-mitigation credits available in the state. The reason is simple: homes built to the current Florida Building Code are engineered to resist hurricane-force wind, and carriers price that resilience in. The catch most builders and lenders gloss over is that those credits are not truly “automatic” the way they sound at closing. You still have to obtain and file the right wind-mitigation paperwork, and the price for insuring the exact same new home can swing widely from one carrier to the next. Here’s exactly how it works.
Short answer: new construction usually costs less to insure — here’s why
A newly built Florida home generally insures for less than a comparable older home because it is the lowest-risk version of itself it will ever be: new roof, new wiring, new plumbing, new HVAC, and construction that meets today’s wind standards. Insurers reward all of that. But “cheaper” is relative — Florida is still a high-cost property market, and a new home in a coastal or high-growth area is not automatically inexpensive to insure. What new construction does is stack the deck in your favor across every rating factor a carrier looks at. The savings are real, but you have to make sure they actually land on your policy.
Florida Building Code and wind mitigation: the credits new homes qualify for
Florida’s statewide building code took effect March 1, 2002, born directly out of Hurricane Andrew’s 1992 destruction, which exposed a patchwork of more than 400 inconsistent local codes. Every home built since then has been required to include hurricane-resistant features — reinforced roof-to-wall connections (straps and clips), stronger roof-deck attachment, and impact or pressure-rated openings in many areas. After Hurricanes Helene and Milton struck in 2024, post-code homes dramatically outperformed older construction in surveys of storm damage.
Because your home was built to the modern code, it qualifies for wind-mitigation credits — discounts on the windstorm portion of your premium that reflect how well the structure resists uplift and water intrusion. These credits are documented on the state’s Uniform Mitigation Verification Inspection Form, OIR-B1-1802, which every Florida property insurer is required to accept. The form records seven construction features, including which version of the building code applied when the permit was pulled. A new home typically scores at or near the top of that form — but the credit only applies once the form is on file. (We break the form down in detail in our guide on the difference between a 4-point and a wind mitigation inspection.)
You still need the paperwork: wind-mit form, certificate of occupancy, builder docs
This is where new buyers get tripped up. The building-code credit is not magic — a carrier has to see proof before it discounts your premium. To capture the full credit on a new build, you’ll generally need:
- A completed wind-mitigation inspection (OIR-B1-1802), signed by a qualifying professional — a licensed home inspector, general/building/residential contractor, professional engineer, or architect. On new construction, the builder or a third-party inspector usually produces this. The form is valid for five years.
- The certificate of occupancy (CO), which confirms the home is finished and permitted for habitation. Carriers often won’t bind a final homeowners policy on a vacant, unfinished structure under the same terms as a completed home.
- Builder documentation — the permit date, plans, and any impact-glass or shutter specifications. The permit date matters because the wind-mit form ties your credit to the code edition in force when construction began.
Note that a fresh form effective April 1, 2026 updates which construction techniques qualify, reflecting a 2024 wind-loss study, so make sure your inspector uses the current version. Without the form, you can pay the same rate as a 20-year-old house sitting right next door — even though your home earned the credit the day it was framed.
Discount categories carriers commonly offer on newer homes
Beyond wind mitigation, newer homes tend to qualify for several discount categories. We frame these by type rather than by a fabricated percentage, because the actual dollar amount varies by carrier and address:
- New-home / age-of-home credit — many carriers apply a discount tied to year built that decreases as the home ages.
- Wind-mitigation credit — the building-code and roof-feature credits described above, applied to the windstorm portion of the premium.
- Roof-related credit — a brand-new roof with a documented age and shape can improve your rating (more on the roof clock below).
- Protective-device / system credits — newer wiring, plumbing, and sometimes monitored alarm or water-leak sensors.
- Bundling — pairing home and auto with one carrier, where available.
The takeaway: a new home doesn’t get one discount, it gets a stack of them — but only the ones you and your agent actually document and request.
Why quotes still vary widely between carriers on the same new home
Here’s the part single-carrier websites won’t tell you: two A-rated carriers can quote meaningfully different premiums on the identical new home, same address, same wind-mit form. That happens because each insurer has its own appetite, reinsurance costs, territory rules, and how aggressively it weighs each mitigation feature. One carrier may be hungry for new construction in your county; another may be capping its exposure there that quarter. This is exactly why shopping a new build across many carriers matters — the “code-built discount” is only as good as the carrier that prices it most favorably for your specific home. As an independent agency, we compare 15-20+ A-rated carriers on one application so the credits land with the company that rewards them most.
The builder’s insurance referral vs. shopping independently
Most production builders have a preferred insurance partner, much like a preferred lender. It’s convenient, and sometimes it’s competitive — but a referral is one quote from one source, and convenience at the closing table is not the same as the best price or the right coverage. We frequently see builder-referred quotes that miss available wind-mit credits, carry coverage limits that don’t match the home’s replacement cost, or simply aren’t shopped against the broader market. There’s nothing wrong with getting the builder’s quote — just treat it as one option, not the only option, and have it compared independently before you bind. You can start an independent quote here and put the builder’s number side by side with the rest of the market.
When to bind coverage during the build — and the hurricane-season catch
Your lender will require homeowners insurance in force at closing, so timing matters — especially during Florida’s June-through-November hurricane season. The catch: once the National Hurricane Center names a storm that threatens Florida, carriers impose a binding moratorium and stop writing or changing wind coverage until the threat passes, often staying in place until 24-78 hours after the storm clears. If your closing lands inside that window and you haven’t bound yet, you can be stuck unable to get a policy and unable to close on schedule. The fix is to lock your quote and bind early — well before the closing date — rather than the day of. We cover the timing rules and what to do if a storm is already named in our piece on buying home insurance during a hurricane in Florida.
What happens as your new home ages (the roof clock starts now)
The discounts that make a new home cheap to insure don’t last forever, and the most important one to track is your roof. Florida’s roof rules under statute reward newer roofs and get stricter with age: for a roof 15 years or older, a carrier can decline to renew based on age unless an inspection shows the roof has five or more years of useful life left. In other words, the clock on your brand-new roof starts the day it’s installed. The same goes for the new-home age credit, which steps down over time. The practical move is to keep your wind-mit form current (re-inspect before it expires every five years), document any roof or system upgrades, and re-shop your policy periodically as the original new-build discounts fade. We explain the age thresholds in detail in our guide to roof age and home insurance in Florida, and you’ll find new-home buying tips throughout our flagship Florida homeowners insurance guide.
