How to pull an impact window permit in Martin County (2026 guide)
Every impact window and door installation in Martin County requires a building permit, including a like-for-like replacement. Incorporated addresses permit through their own city, town or village building department; unincorporated addresses permit through Martin County Building Department. Either way the package is the same — Florida Product Approval documentation, a signed and sealed engineering evaluation of design pressures for the specific address, and a window and door schedule keyed to the elevations — and the permit closes on a final inspection your insurer will ask to see.
Martin County is not one permitting jurisdiction but many. Which counter your package goes to depends on whether your address sits inside a municipality or in unincorporated county, and the two are not interchangeable. This guide covers what the permit requires across Martin County, what has to be in the package, and where the process differs by municipality.

Impact window permits in Martin County at a glance
Every figure below comes from the Florida Building Code, Florida Statutes, or the Miami-Dade test protocols, and the source is named so you can check it.
| Requirement | What the code says | Source |
|---|---|---|
| Permit required for a like-for-like replacement | Yes — there is no matching-what-was-there exemption | Florida Building Code |
| Large missile impact test | A 9 lb (4.1 kg) 2x4 fired from an air cannon at 50 or 80 ft/s | Miami-Dade TAS 201 |

Which building department issues your permit in Martin County
If your address sits inside a municipality, that city, town or village building department issues the permit. If it sits in unincorporated Martin County, Martin County Building Department does. The two are not interchangeable and a package filed at the wrong counter simply comes back. Municipal boundaries here are not intuitive from a mailing address — a property with a city postal address can sit outside that city's limits — so we confirm the jurisdiction from the parcel before anything is ordered.
Martin County sits outside the High Velocity Hurricane Zone
Martin County sits outside the High Velocity Hurricane Zone that covers Miami-Dade and Broward, so products qualify under statewide Florida Product Approval rather than requiring a Miami-Dade Notice of Acceptance. That widens the range of qualifying products rather than lowering the standard. The design pressure your openings must hold is still calculated for your specific address, elevation and roof height — and a coastal property in Martin County routinely calculates higher than an inland property inside the HVHZ. "Outside the zone" is a different approval route, not a lighter window, and it is the single thing homeowners here most often misread when comparing quotes.
What the permit package contains
Three things, and the second is where most incomplete applications fail. First, the Florida Product Approval documentation for every product going in. Second, a window and door schedule keyed to your elevations, so each opening on the drawing maps to a specific approved product and size. Third, a signed and sealed engineering evaluation calculating design pressure for your address and roof height, opening by opening, demonstrating the anchor pattern into your specific substrate — concrete block and wood frame anchor differently, and the calculation has to show which it is.
Association approval runs in parallel, not after
Where a property sits in an association, its written approval normally has to be in hand before the building permit will issue. Associations across Martin County vary enormously — approved-product lists, frame colour, grid pattern, glass tint — so we request the architectural review form from yours and prepare that submission alongside the permit package rather than after it. A review that starts once the permit is already filed is the single most common reason a project loses a month.
Inspections, and why the first one matters most
Expect two. An in-progress inspection of the anchoring happens before the perimeter is sealed, and a final follows once the work is complete. The in-progress stage is the one worth scheduling around: once stucco and interior returns close over the anchors, an inspector can require them opened again. Final sign-off is also what your insurer's wind mitigation inspector will want to see before documenting the credit on form OIR-B1-1802.
How long it takes across the county
It varies, and it varies between neighbouring municipalities in the same county — sometimes by weeks, depending on how each department is staffed that month. Anyone quoting a fixed county-wide turnaround is quoting an average of departments that do not behave alike. We file across Martin County regularly, so we will tell you what it currently looks like in your specific jurisdiction at the quote rather than after you have signed. Manufacturing lead time generally runs alongside the permit rather than after it, so the two overlap instead of stacking.
Florida Product Approval vs Miami-Dade NOA
Martin County is outside the High Velocity Hurricane Zone, so the left-hand column applies here. The right is what a homeowner in Broward or Miami-Dade is working to.
| Florida Product Approval | Miami-Dade NOA | |
|---|---|---|
| Where it applies | Statewide, including Palm Beach, Martin and St. Lucie | Required throughout Miami-Dade and Broward |
| Who issues it | State of Florida, under the Florida Building Commission | Miami-Dade County Product Control |
| Impact testing | Large missile testing where windborne debris protection is required | TAS 201 large missile, then TAS 202 and TAS 203 pressure testing |
| Size of the qualifying product list | Wider — more products carry statewide approval than carry an NOA | Narrower, because fewer assemblies pass the HVHZ protocols |
| What the inspector checks on site | The approval covers the product and the size installed | The NOA number against the exact size installed, not the product line |
| Does it change the design pressure you must hold? | No — that is calculated from your address either way | No — that is calculated from your address either way |
Why Martin County impact window permits get rejected
Plan review sends packages back for the same handful of reasons. None of them are surprises to a contractor who files in this department regularly, and all of them cost you time if the contractor does not.
The approval does not cover the size installed
An Florida Product Approval is specific to tested sizes and configurations, not to a product name. A unit ordered wider than the approval covers fails at inspection even though the product line is approved, and the fix is a reorder rather than a resubmittal.
No signed and sealed engineering for this address
A generic manufacturer chart is not a calculation. The evaluation has to be sealed by a Florida engineer and has to show design pressure for your address, elevation and roof height, opening by opening.
The window and door schedule does not key to the elevations
Every opening on the drawing has to map to a specific approved product and size. A schedule that lists products without tying each to a marked opening is the most common reason a package comes back for more information.
The substrate is not identified
Concrete block and wood frame anchor differently, and the calculation has to show which it is. A submittal that does not say what it is anchoring into cannot be approved on its face.
Association approval is missing
Where a community operates architectural review, its written approval normally has to exist before the building permit will issue. Filing the permit first and the ARC form afterwards is how a project loses a month.
The Notice of Commencement was not recorded and posted
Under Florida Statute 713.135 it has to be recorded with the county and posted at the property before the first inspection. An inspector who arrives to find no posted notice cannot pass the inspection.
Egress is not met on a bedroom opening
Replacing an operating window with a smaller operable area can drop a bedroom below the clear opening egress code requires. It is caught at plan review if the schedule is honest and at inspection if it is not.
How we pull a Martin County impact window permit, step by step
Free measurement and jurisdiction check
We measure every opening and establish from the parcel whether your address permits through a municipality or through Martin County Building Department. That determines the submittal format before anything else is decided.
Product selection against the approval route
Products are chosen from those holding Florida Product Approval, within whatever your association's approved list allows, and sized to the design pressure calculated for your address.
Engineering and the permit package
A signed and sealed evaluation calculates design pressure and anchor pattern opening by opening. That goes in with the product approval documents and a window and door schedule keyed to your elevations.
Association submission, in parallel
Where architectural review applies, we request the ARC form and file that submission alongside the permit rather than waiting for one to clear the other.
Permit issued, installation scheduled
We collect the permit and schedule around your calendar. You sign the application as the property owner; that is the only paperwork that needs you.
In-progress inspection, then final
The anchoring is inspected before the perimeter is sealed, then a final inspection closes the permit. We book both and meet the inspector at each.
