Impact Windows in Fort Lauderdale

If you own a home in Fort Lauderdale, impact protection is not a premium upgrade you are being upsold. It is a code requirement — and understanding exactly what the code says is the difference between buying well and overpaying.

Every glazed opening in Fort Lauderdale must be protected — that is the law

Fort Lauderdale sits in Broward County, one of only two Florida counties (with Miami-Dade) designated a High-Velocity Hurricane Zone. Under the HVHZ provisions of the Florida Building Code, every exterior glazed opening — every window, every glass door, every skylight — must either be impact-rated or protected by a permanent, code-approved shutter system. There is no third option, and there is no exemption for being a few miles inland.

This is why the conversation in Fort Lauderdale is never “do I need protection.” It is “impact glass or shutters,” and that is a genuine trade-off worth thinking through rather than being sold on.

What an HVHZ-rated window actually survives

The certification bar here is meaningfully higher than the rest of the state, and the tests are not abstract:

• Large-missile impact (TAS 201). A nine-pound 2×4 is fired at the glass at roughly 50 feet per second. The assembly has to take the hit.
• Cyclic pressure loading (TAS 203). After being struck, the window is then subjected to on the order of 9,000 pressure cycles simulating the sustained push-and-pull of a hurricane's pressure field.
• Water and air resistance (TAS 202). And it has to still keep water out afterwards.

Critically: in the HVHZ, a product must carry a Miami-Dade Notice of Acceptance (NOA) or an HVHZ-rated Florida Product Approval. A statewide Florida Product Approval on its own is not sufficient in Fort Lauderdale. This is the most common and most expensive misunderstanding in the entire category — a window can be genuinely “hurricane rated” and still be illegal to install on your house.

Ask for the NOA number. Any legitimate installer will hand it over without hesitating, because it has to go on the permit anyway.

Impact glass vs. shutters — an honest comparison

Both satisfy code. They are not equivalent products.

• Impact windows are always on. No deployment, no storing panels, no climbing a ladder in a rising wind. They also cut exterior noise, block the large majority of UV, and improve the thermal envelope year-round. They cost considerably more up front, and installation means replacing the actual window unit.
• Shutters cost far less up front and satisfy the same requirement. But they only work if someone deploys them, and they do nothing for noise, UV or energy efficiency for the other 51 weeks of the year. For an owner who travels, or an older homeowner, “only works if deployed” is a real limitation and not a theoretical one.

Insurers frequently price the two differently as well, which belongs in the calculation.

The money: wind mitigation and My Safe Florida Home

Two things can reduce what this actually costs you.

Wind mitigation credits. Once every opening on the home is protected, a wind mitigation inspection can document full opening protection — one of the features Florida insurers weight most heavily. In the Broward market that can move a premium in a way that compounds over the years you hold the home.

My Safe Florida Home. The state program provides a free wind-mitigation inspection to eligible homeowners and a 2:1 matching grant — the state contributes $2 for every $1 the homeowner puts in — up to $10,000. Eligibility is income-based, and applicants aged 60 and over have been prioritized in the queue. The program has been funded in successive cycles and the Legislature reappropriated substantial additional funding in 2026 to work through a backlog of homeowners who completed an inspection but had not yet received an award.

Funding cycles open and close, and the queue moves.

Fort Lauderdale specifics

Fort Lauderdale is the most architecturally mixed city on this list. Post-war ranch homes east of Federal Highway sit a few blocks from new construction, and the canal network means a large number of properties are within a short distance of salt water. That proximity matters: airborne salt accelerates corrosion on fasteners, flashing, condenser coils and mounting hardware, and it is the single biggest reason identical components fail faster here than they do ten miles inland.

The eastern neighborhoods carry a lot of 1950s and 1960s housing stock, which frequently means original or lightly updated building envelopes that predate every modern wind provision.

Permits, and how to vet an installer

Window and door replacement in Fort Lauderdale requires a permit, and the NOA numbers for the specific products go on the application. Installation matters as much as the product: an NOA-approved window fastened into the opening incorrectly is not a code-compliant assembly, and the anchoring schedule in the approval document is the part that inexperienced installers get wrong.

Before you sign: verify the contractor's license at myfloridalicense.com (look for Current/Active with no open discipline), ask for a certificate of insurance, and ask to see the NOA for the exact product being quoted — not the manufacturer's brochure.

Frequently asked questions

Are impact windows actually required in Fort Lauderdale?

Protection is required. Fort Lauderdale is in the High-Velocity Hurricane Zone, where every exterior glazed opening must be impact-rated or covered by a permanent code-approved shutter system. You may choose which route, but you may not choose neither.

Is a 'hurricane rated' window automatically legal here?

No — and this is the costly mistake. In Broward and Miami-Dade, a product needs a Miami-Dade NOA or an HVHZ-rated Florida Product Approval. A statewide Florida Product Approval alone is not enough. Always ask for the NOA number.

How much can My Safe Florida Home cover?

The program offers a 2:1 match — $2 of state money per $1 you contribute — up to $10,000, plus a free wind-mitigation inspection for eligible homeowners. Eligibility is income-based and funding runs in cycles, so check mysafeflhome.com for current status.

Will impact windows lower my insurance?

They can. Full opening protection is one of the features a wind mitigation inspection documents, and Florida insurers weight it heavily. The size of the credit depends on your carrier and the rest of the home's mitigation features, so ask your agent to price it before you commit.
