Almost every Florida county requires a building permit for window replacement. The permit fee is small relative to the project cost, but the process matters — improperly permitted windows can cause home-sale closings to fail and trigger expensive after-the-fact permitting and engineering.
This guide breaks down realistic FL window permit costs by county, what the permit process involves, and how to avoid the common mistakes.
Why FL requires window permits
Three reasons:
- Hurricane code compliance — windows must meet Florida Building Code R609 for wind load and impact resistance. The permit process verifies that the installed product has a valid Florida Product Approval (FPA) number and is rated for your county's design wind speed.
- Insurance documentation — your homeowners insurance carrier will ask for the OIR-B1-1802 Wind Mitigation Form, which requires permit documentation to verify the install. Without permits, you cannot claim the impact-window discount on your insurance.
- Home-sale documentation — at closing, the buyer's lender or inspector will check for permits on visible improvements. Unpermitted windows in the public records can hold up closings.
Permit costs by FL county (2026)
Costs vary by county and HVHZ designation:
| County | Permit fee | HVHZ? | Process time |
|---|---|---|---|
| Miami-Dade | $150–$400/window | Yes | 7–14 business days |
| Broward | $130–$350/window | Yes | 5–12 days |
| Palm Beach | $100–$250/window | No (most) | 5–10 days |
| Hillsborough (Tampa) | $75–$175/window | No | 5–10 days |
| Pinellas | $75–$175/window | No | 5–10 days |
| Orange (Orlando) | $70–$150/window | No | 5–10 days |
| Duval (Jacksonville) | $65–$150/window | No | 7–14 days |
| Lee (Fort Myers) | $85–$180/window | No | 5–10 days |
| Collier (Naples) | $90–$200/window | No | 7–14 days |
| Sarasota | $85–$180/window | No | 5–12 days |
These are the permit fee ranges per window. Most FL window contractors include permit handling in their installed price; verify it's in scope before signing.
What the permit process involves
For a typical FL window replacement permit:
- Application submission — contractor or homeowner submits permit application to county/city building department with:
- Window product Florida Product Approval (FPA) numbers
- Installation drawings
- Fastener specifications
- For HVHZ counties: engineer-stamped drawings showing wind load calculations
- Plan review (5–14 business days depending on county) — building department verifies FPA numbers are current, fastener pattern meets code, structural attachment is appropriate
- Permit issuance — typically $0.50–$1.20 per sqft of glass area, plus base permit fee
- Installation — windows installed per the approved drawings
- Inspection (1–3 business days after install) — inspector visits to verify install matches approved drawings
- Final certificate — permit closes, becomes part of the home's public record
HVHZ counties have additional requirements
In Miami-Dade and Broward (the HVHZ — High Velocity Hurricane Zone):
- Windows must have Miami-Dade County Notice of Acceptance (NOA), not just standard FPA
- Engineer-stamped installation drawings are required (adds $400–$900 to engineering cost)
- Fastener pattern is stricter — typically 6 fasteners per side instead of 4
- Permit review can take 10–14 business days versus 5–10 in non-HVHZ counties
The total HVHZ permit + engineering cost typically adds $300–$700 to a typical multi-window project — a meaningful but unavoidable expense.
What HOA requires
In addition to the building permit, many FL HOAs require:
- Architectural review approval — the HOA confirms the window style, color, and visual impact are consistent with neighborhood standards
- Pre-installation notification — typically 30 days before install
- Post-installation inspection — HOA verifies the install matches the approved style
HOA review typically costs $50–$200 in administrative fees but cannot proceed until the building permit is in place. Allow an additional 2–4 weeks for HOA review on top of the building permit timeline.
When you do NOT need a permit
A handful of cases:
- Same-size, same-style replacement in non-HVHZ counties — some counties allow exemption for like-for-like replacement with no structural changes
- Repair (single broken pane) — typically does not require a permit, just a glass company service call
- Storm-related emergency replacement — most FL counties have expedited or waived permit processes for FEMA-disaster-area repair
Check with your specific county; rules vary.
Cost of skipping permits
The most common mistake is installing without a permit to save the fee. Costs of this mistake:
Home-sale closing problems
When you sell the home, the buyer's lender or inspector will check the county records for permits on visible improvements. Unpermitted windows show up as:
- Closing delay (typical: 4–8 weeks while permits are obtained after the fact)
- After-the-fact permit fees (typically 2–3x the original permit cost)
- Engineering review (if windows are installed and require structural verification)
- Possible window removal and reinstall if installation doesn't meet code
Total cost of unwinding an unpermitted install: typically $1,500–$5,000 per window plus 4–8 weeks of closing delay.
Insurance discount loss
Without permit documentation, your insurance carrier will not credit you for the impact-window discount on the wind mitigation form. That is potentially $200–$1,500/year in lost insurance discount depending on county and policy.
Code-compliance risk
If your windows are installed without permits and a hurricane causes water intrusion or structural failure, insurance claim adjusters can deny coverage based on uncertain code-compliance. We see this in the post-Ian (2022) insurance landscape — adjusters are more aggressive about denying claims on unpermitted work.
Permit timing realities
The honest timeline for FL window replacement:
- Get 3 contractor quotes: 1–2 weeks
- Pick contractor and order windows: 2–4 weeks for vinyl, 4–8 weeks for custom/impact
- Contractor pulls permit: 1–3 weeks (longer in HVHZ)
- HOA review (if applicable): 2–4 weeks
- Window installation: 1–3 days
- Inspection scheduling: 3–7 business days
- Final certificate: 1–2 weeks after inspection
Total elapsed time from initial quote to permit-closed install: 8–16 weeks for typical FL projects, 12–20 weeks for HVHZ projects.
The verdict
FL window permits cost $75–$400 per window depending on county and HVHZ status. They typically take 5–14 business days to obtain. The process is straightforward if your contractor handles it (most do).
Skip the permit at your own risk — the cost of unwinding unpermitted installs at home sale is typically 2–5x the permit fee, and you also lose the insurance discount and code-compliance documentation.
