Impact Window Permit Guide: Broward, Miami-Dade & Palm Beach County 2026
Quick answer: Impact window permits in South Florida typically cost $150–$500 depending on the city and project value, and take 1–3 weeks for approval. You'll need the product's Miami-Dade NOA or Florida Product Approval documents, and in almost every case a licensed contractor pulls the permit for you as part of the installation.
Every impact window replacement in South Florida requires a building permit — no exceptions. But the timeline, documentation requirements, and fees differ significantly between the three major counties. This guide gives you the exact playbook for each jurisdiction so you don't get stuck waiting or fail an inspection.
Updated: July 2026 | Applies to: Broward, Miami-Dade, and Palm Beach Counties
Why You Can't Skip the Permit
Florida Building Code §105.1 requires a permit for any work that alters the building envelope — and swapping a standard window for an impact window qualifies, even if you don't change the opening size. Installing without a permit creates three serious risks:
- Insurance denial: Your carrier can deny a hurricane damage claim if unpermitted work is involved in the loss.
- Lien risk: Without a recorded Notice of Commencement (NOC), the property may be exposed to mechanic's liens from suppliers.
- Resale issues: Unpermitted work triggers title and inspection problems when you sell.
- Code violation fines: County enforcement can issue stop-work orders, require removal, and levy daily fines.
The permit also protects you — it guarantees an independent inspector confirms the installation meets wind-load requirements. A licensed contractor like Vieser Construction handles the entire permit process as part of the project.
County-by-County Quick Comparison
| Factor | Broward County | Miami-Dade County | Palm Beach County |
|---|---|---|---|
| Wind Zone | HVHZ (entire county) | HVHZ (entire county) | WBDR — not HVHZ |
| Product Standard | Miami-Dade NOA required | Miami-Dade NOA required | FL# Product Approval or NOA |
| Review — Incorporated City | 21–25 business days | 5–10 business days | 14–25 business days |
| Review — Unincorporated | 30–50 business days | N/A (all MDPD) | 21–35 business days |
| Total Timeline | 6–10 weeks | 4–6 weeks | 3–6 weeks |
| Permit Fee Range | ~1.5–3% of project value | Varies by municipality | ~1.5–2.5% of project value |
| NOC Required | Yes — projects ≥$2,500 | Yes — projects ≥$2,500 | Yes — projects ≥$2,500 |
| Sealed Engineer Plans | Required | Required | Required |
Broward County: HVHZ Rules Apply Everywhere
Broward County sits entirely inside the High-Velocity Hurricane Zone (HVHZ). Every municipality — Fort Lauderdale, Hollywood, Miramar, Pembroke Pines, Coral Springs, Deerfield Beach, Pompano Beach, Davie — enforces the same HVHZ product standard: your windows must carry a current Miami-Dade Notice of Acceptance (NOA).
Broward Permit Timeline
- Incorporated cities (Fort Lauderdale, Hollywood, etc.): 21–25 business days for first-review approval on complete submittals.
- Unincorporated Broward (governed by Broward County Building Code Services): 30–50 business days.
- Inspection deadline: At least one inspection must pass within 180 days of permit issuance or the permit expires.
- If permit expires: You must re-apply and pay fees again — do not let this happen.
Broward Permit Checklist
- ✅ Contractor's CGC or CBC license copy
- ✅ Contractor's general liability + workers' comp certificate
- ✅ Signed and sealed plans from a Florida-licensed engineer
- ✅ Product NOA pages for every window/door model
- ✅ Miami-Dade NOA — FL# alone is NOT sufficient in Broward HVHZ
- ✅ Notice of Commencement (NOC) recorded with Broward County Clerk
- ✅ Certified copy of NOC posted at job site before first inspection
- ✅ Permit placard posted at site during all work
Broward Permit Fees
Each city sets its own fee schedule, but the general range is 1.5%–3% of total contract value. Example: a $15,000 project generates roughly $225–$450 in permit fees. Additional charges may include plan review fees, technology surcharges, and DCA surcharges.
Expedited review is available in most Broward cities for an additional fee — typically 50%–100% of the base permit fee. Ask your contractor if expedite review is worth it given your project deadline.
Miami-Dade County: Strictest Standards in the State
Miami-Dade is entirely HVHZ and is the origin of the Miami-Dade NOA system — the toughest product-approval standard in the United States. Every window, door, and skylight installed in Miami-Dade must carry a valid, current Miami-Dade NOA. NOAs expire annually and manufacturers must pass annual factory inspections to renew. If a product's NOA has lapsed, it cannot be used on any new permit application.
Miami-Dade Permit Timeline
- Plan review: 1–10 business days (Miami-Dade BORA offers expedite options).
- Total timeline (application to final inspection): 4–6 weeks for typical residential jobs.
- Key rule: Even replacing a single window in Miami-Dade requires a permit with a current NOA product. There is no "small project" exemption.
Miami-Dade NOA: What You Must Verify
⚠️ NOA Expiration Is a Real Risk
- ✅ Confirm NOA expiration date before ordering product — expired NOAs cannot be used on new permits
- ✅ PGT WinGuard, ESW, and Mr. Glass all carry current Miami-Dade NOAs as of 2026
- ✅ Some smaller brands have let NOAs lapse — always verify at miamidade.gov/building
- ✅ NOA pages must be submitted with permit application
- ✅ Inspector will verify NOA on site
Miami-Dade Permit Checklist
- ✅ Contractor's CGC or CBC license copy (Florida-licensed)
- ✅ Liability + workers' comp insurance certificates
- ✅ Signed and sealed structural plans by Florida PE
- ✅ Current Miami-Dade NOA pages for each product — check expiration dates
- ✅ Notice of Commencement recorded with Miami-Dade Clerk before work begins
- ✅ Certified copy of NOC posted at job site before first inspection
- ✅ Permit placard posted visibly at site
- ✅ For threshold buildings (3+ stories): Special Inspector required per 2026 binding interpretation
Threshold Building Rule — New for 2026
A January 2026 Binding Interpretation of the 8th Edition FBC (ratified by the Florida Building Code Commission on January 26, 2026) now requires that window and door installations in threshold buildings (generally 3+ stories or buildings over 50,000 sq ft) must use a State of Florida certified Special Inspector in addition to the standard permit inspection process. This adds cost and scheduling complexity to high-rise condo work across all three counties.
Palm Beach County: WBDR — Different Rules, Same Rigor
Palm Beach County is not in the HVHZ, but it is entirely within Florida's Wind-Borne Debris Region (WBDR). This distinction matters: instead of requiring a Miami-Dade NOA, Palm Beach allows the broader Florida Product Approval (FL#) certification — though NOA-certified products are also accepted.
With the 9th Edition Florida Building Code taking effect December 31, 2026, the WBDR boundary will expand significantly — eliminating the 1-mile coastal restriction at 130 mph design wind speed. Many Palm Beach County addresses that are currently unregulated will be pulled into the WBDR under the new code.
Palm Beach Permit Timeline
- City-level review (West Palm Beach, Boca Raton, Delray Beach, Boynton Beach, etc.): 14–25 business days.
- Unincorporated Palm Beach County (Palm Beach County Building Division): 21–35 business days.
- Total timeline: 3–6 weeks from application to final inspection — fastest of the three counties.
FL# vs NOA: Know Your Address
| Certification | HVHZ (Broward/Miami-Dade) | WBDR (Palm Beach) |
|---|---|---|
| Miami-Dade NOA | ✅ Required & sufficient | ✅ Accepted (exceeds FL#) |
| Florida Product Approval (FL#) | ❌ Not sufficient alone | ✅ Accepted |
| PGT WinGuard | ✅ Has current NOA | ✅ Has FL# + NOA |
| ESW Impact | ✅ Has current NOA | ✅ Has FL# + NOA |
| Mr. Glass | ✅ Has current NOA | ✅ Has FL# + NOA |
Palm Beach Permit Checklist
- ✅ Contractor's CGC or CBC license copy
- ✅ Liability + workers' comp insurance certificates
- ✅ Signed and sealed plans with Chapter 16 wind-load calculations
- ✅ Current FL# product approval sheets or NOA pages for each product
- ✅ Notice of Commencement (NOC) recorded with Palm Beach County Clerk — projects ≥$2,500
- ✅ Certified copy of NOC posted at job site before first inspection
- ✅ Confirm whether address is incorporated city or unincorporated county — determines which portal to use
Notice of Commencement (NOC): Required on Nearly Every Job
A Notice of Commencement (NOC) is required for any construction project in Florida with a total cost of $2,500 or more — including labor and materials. Since almost any impact window job exceeds this threshold, assume the NOC is required.
| NOC Requirement | Details |
|---|---|
| Threshold | Project cost ≥$2,500 (labor + materials) |
| Who records it | Property owner or contractor, at the county Clerk's office |
| Timing | Before work begins; certified copy must be at job site before first inspection |
| Why it matters | Protects the owner from mechanic's liens from subcontractors or material suppliers |
| Expiration | 1 year from recording date (can be extended) |
| Cost to record | Typically $10–$30 depending on county Clerk fees |
Vieser Construction handles NOC preparation and recording as a standard part of every permitted job. You never have to navigate this yourself.
7 Things That Delay Permit Approval
Most permit rejections and delays come from the same avoidable mistakes:
Expired NOA on the product spec sheet
Fix: Always verify NOA expiration date at miamidade.gov/building before submitting
Sealed plans don't match the NOA installation details
Fix: Engineer's plans must reference the exact NOA number and follow the approved installation drawings
Contractor license not active at time of submission
Fix: Verify contractor DBPR license status at myfloridalicense.com before starting
NOC not recorded before first inspection request
Fix: Record NOC at county Clerk and bring certified copy to job site before scheduling any inspection
Wrong jurisdiction — filed with city when address is unincorporated (or vice versa)
Fix: Confirm your parcel's jurisdiction using the county property appraiser's website
Missing insurance certificate
Fix: Both general liability and workers' comp certificates must be current and name the county/city as certificate holder
Incomplete site plan — no existing window schedule or opening dimensions
Fix: Include a window schedule listing every opening, its dimensions, DP rating, and corresponding NOA/FL# product
Start Your Permit Before December 31, 2026
The Florida Building Code 9th Edition takes effect on December 31, 2026. Projects permitted before that date are governed by the 8th Edition requirements in force at the time of permit application. This matters because the 9th Edition brings significant changes — including WBDR boundary expansion and new multifamily requirements.
Deadline Math by County
- Palm Beach County (3–6 week review): Submit permit application by November 1, 2026 to receive permit under 8th Edition rules
- Broward County — incorporated cities (21–25 business days): Submit by October 15, 2026
- Broward County — unincorporated (30–50 business days): Submit by September 1, 2026
- Miami-Dade County (4–6 weeks total): Submit by October 15, 2026
Note: "Governed by 8th Edition" typically means the code in effect when the permit is issued — confirm with your local building department, as timing rules can vary.
If you're in a WBDR-adjacent area of Palm Beach County that will be pulled into the new WBDR boundary under the 9th Edition, installing impact windows now — before December 31, 2026 — lets you comply at today's product standard rather than potentially stricter future requirements.
Inspection Types: What to Expect
| Inspection | When | Inspector Checks |
|---|---|---|
| Rough-in / Framing | After old windows removed, new frames set — before finishing | Buck framing, anchor pattern, flashing, NOA compliance |
| Final Inspection | After installation complete, sealant applied | Hardware function, glazing labels, sealant, screen/hardware, NOA label on product |
| Special Inspection (threshold buildings) | Required per 2026 binding interpretation for 3+ story buildings | Performed by FL-certified Special Inspector per special inspection plan |
The NOA label must remain on the glass until after the final inspection. Do not allow your crew to peel labels before the inspector has signed off — this is a common cause of failed finals.
Frequently Asked Questions
Do I need a permit to replace impact windows in South Florida?
Yes. Any window replacement that alters the building envelope requires a permit in Broward, Miami-Dade, and Palm Beach County — including impact window swaps even if the opening size stays the same.
What is the difference between a Miami-Dade NOA and a Florida Product Approval (FL#)?
A Miami-Dade NOA meets the strictest HVHZ standard and is required in both Miami-Dade and Broward counties. A Florida Product Approval (FL#) is a statewide certification acceptable in non-HVHZ areas like Palm Beach County. All NOA-approved products also carry a FL#, but not vice versa.
How long does a Broward County impact window permit take?
Incorporated Broward cities (Fort Lauderdale, Hollywood, Coral Springs, Miramar) typically run 21–25 business days for first-review approval. Unincorporated Broward County takes 30–50 business days. Total project timeline from application to final inspection is usually 6–10 weeks.
When is a Notice of Commencement (NOC) required for impact windows in Florida?
A Notice of Commencement is required for any impact window project with a total cost of $2,500 or more. It must be recorded with the county Clerk before work begins, and a certified copy must be posted at the job site before the first inspection.
How much does an impact window permit cost in South Florida?
Permit fees are calculated as a percentage of project value — typically 1.5%–3% of total contract value, plus plan review fees. A $15,000 impact window project would typically generate $225–$450 in permit fees, not including expedite fees or special inspection fees for threshold buildings.
Is Palm Beach County in the HVHZ?
No. Palm Beach County is in the Wind-Borne Debris Region (WBDR) but NOT in the High-Velocity Hurricane Zone (HVHZ). This means Florida Product Approval (FL#) numbers are acceptable — Miami-Dade NOA is not required, though NOA products are also permitted.
