In Florida, home hardening primarily means strengthening your home's roof, walls, windows, doors, and garage door so they can better resist hurricane-force winds and flying debris. It typically involves reinforcing your roof, upgrading windows and doors, and securing anything outside that could become a projectile in a storm.
Florida homeowners may be eligible for state assistance in the form of a free home inspection, a matching construction grant, and a sales tax refund on qualifying purchases. Making specific home improvements could even help you save money on your Florida home insurance through wind mitigation credits insurers are required to offer.
Start with a free wind mitigation inspection
The My Safe Florida Home Program, administered by the Florida Department of Financial Services, provides free home inspections for qualifying homeowners. Funding cycles open and close over time — check the program's site for current application status. If the program isn't accepting applications when you're ready to start, you can still get a wind mitigation inspection from a licensed inspector at your own cost.
Either way, the inspection results in a standardized report — Florida's wind mitigation form — that documents your home's wind-resistant features. This is what insurers use to calculate discounts. Under Florida Statute 627.0629, insurers must discount the windstorm portion of your home insurance when you make specific wind mitigation upgrades.
If you go through My Safe Florida Home, your inspection report will also include recommended improvements and cost estimates. You can share the report with your home insurer to make sure you're currently receiving all eligible discounts.
Harden your roof first
Whether you apply for a free home inspection from the state or not, these improvements can help your roof withstand strong winds and remain intact.
-
Roof deck attachment: Your roof deck is attached to your home using nails. Upgrading to 8D ring-shank nails and spacing them closer together can help increase your roof’s wind resistance.
-
Roof-to-wall connections: Florida Building Code has required hurricane clips or straps on new construction and re-roofing projects statewide since 2002, with stricter standards in high-velocity wind zones like Miami-Dade and Broward counties.
-
Secondary water resistance: Adding a secondary protective barrier beneath your outer roof materials can help prevent water from entering your home if the roof covering gets damaged or ripped away.
-
Gable end bracing (only applies to gable roofs): Gabled roofs have two sloped slides that join together to form a triangle. Installing braces in your attic that press against the gable end and extend at least six feet into the attic can help distribute wind pressure across a larger surface area of the roof, absorbing the impact of high winds.
The shape of your roof (gable vs. hip) affects your home’s wind resistance, but restructuring your roof would be a large, costly project. It's likely better to focus on strengthening the building as it currently exists.
Protect every opening
Reinforcing or replacing your windows and doors can help prevent damage from strong winds or airborne projectiles.
-
Exterior doors: Impact-resistant exterior doors can better withstand wind and windborne debris. For double-entry doors, consider putting in a heavy-duty deadbolt, adding slide bolts for the inactive door, and using longer attachment screws to install hinges.
-
Stronger windows: Impact-resistant windows and hurricane shutters can resist damage from wind and projectiles and prevent water or debris from entering the home. They can also help prevent internal pressure from building up in the home during a windstorm.
-
Garage doors: Because of its size, the garage door may represent the most vulnerable opening of your home, and winds entering the garage can lift your roof clear off the structure. Reinforcing your garage doors can help keep out wind and debris and even protect your roof.
Note: To get the strongest score for opening protection in the My Safe Florida Home inspection report, all doors, garage doors, skylights, windows and other openings must be rated at the highest level. Even one unprotected opening can potentially eliminate the discount.
Handle the yard and the small stuff
Taking care of the areas outside your home can also protect your home during high winds.
-
Trim your trees: Cut off dead or heavy limbs from trees on a regular basis to prevent them from turning into airborne debris.
-
Securing loose items: Tie down or put away furniture, grills, yard toys, equipment, and anything else that could be picked up by strong winds. Even extremely heavy items can tip over, so make sure you’re securing anything that’s loose.
-
Check drainage systems: Clean your gutters and extend downspouts farther away from your home to keep water off your roof and away from your foundation.
How to pay for home hardening with grants
After you get a home inspection from the My Safe Florida Home Program, you may qualify to receive a matching construction grant to help you pay for home hardening improvements recommended by the report.
Matching grants
For eligible homeowners who can pay part of the project cost upfront, the grant provides $2 for every $1 spent on wind mitigation improvements recommended in the inspection report, up to $10,000. Funds are released as a reimbursement once the work is completed and paid for by the homeowner. Homeowners typically need to spend at least $15,000 on the project to receive the full $10,000.
Low-income grants
For low-income homeowners, the grant can provide up to $10,000 for wind mitigation projects recommended in the report, with no out-of-pocket requirement. The invoice does not need to be paid in full for the homeowner to receive the grant.
Who is eligible for grant funding?
Eligibility rules can change between funding cycles, so verify current requirements at mysafeflhome.com before applying — but as of this writing, you must meet the following requirements to qualify for a grant:
-
The homeowner may need to meet a household income limit, depending on the current funding cycle.
-
The home must be a single-family home on an individual parcel of land or a townhome.
-
The home must be built on site and occupied by the owner (no mobile homes, second homes, vacation homes, or rental properties).
-
The homeowner must have a homestead exemption on file.
-
The home must have received an initial inspection through the My Safe Florida Home Program.
-
The home must have an insured value of $700,000 or less.
-
The building permit application for the construction of the home must have been submitted before Jan. 1, 2008.
-
The homeowner must provide information about the contractor selected to perform the wind mitigation work.
-
The homeowner must make the home available for a final inspection once the project is complete.
-
The homeowner must agree to supply information received from their home insurance provider about discounts applied based on the work completed.
Pro tip: Florida is currently running a pilot version of this program for condo owners. For more information, visit the My Safe Florida Condo Pilot Project.
How grant application phases work
Grant availability is prioritized based on the age and income of the applicant. The program starts with the highest priority groups first, before approving applicants of other groups on a phased schedule:
|
Priority 1 (highest) |
Applicants who are low income and are at least 60 years of age |
|
Priority 2 |
Applicants who are low income and are younger than 60 |
|
Priority 3 |
Applicants who are of moderate income and are at least 60 years of age |
|
Priority 4 |
Applicants who are of moderate income and are younger than 60 |
|
Priority 5 (lowest) |
Applicants of all ages who are above the moderate income threshold. These applicants are ineligible to receive a grant but may get an inspection |
As part of the application, you must select at least one recommended home improvement from the report and a licensed contractor to complete the work. If the report did not include any recommended improvements, you cannot move forward with a grant.
How home hardening tax breaks can help Florida homeowners
Separately from the grant program, Florida also offers a sales tax break on some hardening purchases. Starting July 1, 2026 and running through June 30, 2029, Florida homeowners can apply for a refund of the state sales tax paid on qualifying impact-resistant windows, exterior doors, and garage doors. You get reimbursed by submitting a request, along with copies of your receipts and proof of payment, to the Florida Department of Revenue. The total reimbursement caps at $500 per property, and the refund is only available to the homeowner of the property where the products were installed.
What hardening does (and doesn’t) do for your insurance
Hardening your home against wind can save you money on Florida home insurance, but it's worth understanding exactly what that savings covers — and what it doesn't.
How hardening can lower your home insurance costs
Under Florida law, insurers must discount the windstorm portion of your home insurance when you make specific wind mitigation upgrades — this applies only to that part of your bill, not your entire premium.
-
Share your initial inspection report with your insurer: Once your inspection is complete, share the report to check if you're already getting all the policy discounts your home qualifies for.
-
Complete recommended improvements, then submit your final report: Your inspection report tells you which upgrades would unlock additional discounts. Once the work and your final inspection are both done, submit the updated report to your insurer to claim the savings. Submitting before the work is finished won't count.
What hardening doesn't change
-
It doesn't reduce your flood risk. Wind mitigation upgrades protect against wind and windborne debris, not water. If you're in a flood-prone area, you'll need separate flood insurance to cover storm surge and flooding.
-
It doesn't lower your hurricane deductible. Florida hurricane deductibles are typically a percentage of your dwelling coverage limit, and that percentage doesn't change based on how hardened your home is. What hardening does is reduce your odds of needing to file a claim in the first place.
Frequently asked questions
What is the Florida $10,000 grant for homeowners?
Florida provides grants of up to $10,000 for specific upgrades that strengthen your home’s resistance to wind. Depending on your income level, you may qualify for a matching grant, where the state provides $2 for every $1 spent, or a low-income grant, which doesn't require the homeowner to pay a matching amount or submit a paid-in-full invoice.
What is the Florida home hardening tax exemption?
Florida offers a refund of the sales tax paid on qualifying impact-resistant windows, doors, and garage doors — not a point-of-sale exemption, so you'll still pay the tax at checkout. You can apply to the Florida Department of Revenue for reimbursement of up to $500 per property for purchases made July 1, 2026 through June 30, 2029.
Does Florida really have a window replacement program?
There is no standalone window replacement program. Avoid any contractor offering you “free windows” through state funding. However, impact windows may qualify for a grant under the My Safe Florida Home program. You can also apply to get a refund for sales tax paid on impact-resistant window purchases in Florida.
What wind speed are Florida houses built to withstand?
Design wind speeds vary by location, but Florida's building code requires homes to withstand some of the highest wind loads in the country. Inland areas are typically built to around 130 to 140 mph, while coastal regions along the Gulf and Atlantic can require 150 to 170+ mph. The strictest standards apply in Miami-Dade and Broward counties — Florida's High-Velocity Hurricane Zone (HVHZ) — where homes must be built to withstand 175 mph and 170 mph, respectively. Homes built before the 2002 statewide building code went into effect may not meet these current standards.
