Boca Raton Impact Windows: Permit, Cost & 25% Rule (2026)

What Is Boca Raton's Wind Zone, Exactly?

Boca Raton is not part of the High Velocity Hurricane Zone — that designation only covers Miami-Dade and Broward. But all of Boca Raton falls inside the Wind-Borne Debris Region under the Florida Building Code. The practical implications for Boca homeowners:

Design wind speed: 160–170 mph (varies by exposure category and proximity to the Atlantic)
Florida Product Approval (FPA) acceptable, or Miami-Dade NOA — both work
Permits required for replacement through City of Boca Raton Building Division
25% rule applies for existing homes permitted before March 1, 2002 (see below)
Coastal A1A-adjacent neighborhoods (Boca Beach, Spanish River, Royal Palm Yacht Club, Por la Mar) see the highest design pressures

The City of Boca Raton runs its own building department separate from Palm Beach County. Permits for projects inside city limits go through the city's online portal, Boca eHub (myboca.us/ehub).

How the 25% Rule Actually Works in Boca Raton

This is where Boca homeowners get tripped up. Read carefully: The rule: This exemption (Florida Building Code — Existing Building §707.4) only applies to one- and two-family homes permitted before March 1, 2002. For those homes, if you replace more than 25% of the glazed opening area within a rolling 12-month period, every replacement window must be impact-rated (or paired with approved shutters). Stay at or under 25% and the replacements can skip impact protection — though they still must meet the design wind pressures for your site. Homes permitted under the 2002 Florida Building Code or later don't get the exemption: replacement windows there need impact protection regardless of how many you swap. What "glazed opening area" means: It's measured in square feet, not in window count. A single 8 ft × 6 ft sliding glass door (48 sq ft) can equal six 4 ft × 2 ft single-hung windows. The trap: Homeowners replace 5 windows in March, then another 4 in October "because the contractor was already in the area." That second project pushes them past 25%, and now both projects are subject to retroactive code review. What this means in practice: If you're planning to do windows in phases for budget reasons, calculate the total area you'll replace within 12 months before starting. If you're going past 25%, every window in the project must be impact-rated from the start. → Talk to a licensed Boca Raton window installer free

FAQ: The Questions Boca Raton Homeowners Actually Ask

Q: Do I need impact glass if I have hurricane shutters?

No. Florida Building Code accepts either impact-rated glass or approved hurricane shutters as opening protection in the WBDR. Many Boca homeowners keep older non-impact windows behind shutters and only upgrade to impact glass when a window fails or they renovate. The trade-off: shutters need deployment before every storm, no daily benefits, and some insurers offer lower wind-mit credits for shutter-protected vs. impact-protected openings.

Q: My HOA limits window frame color. Does that override Florida Building Code?

No — code is the floor; the HOA can be more restrictive but not less. Many Boca communities (Boca West, Royal Palm Yacht & Country Club, St. Andrews, Boca Pointe, The Polo Club) have strict architectural review requirements. You'll likely need both HOA written approval and a permit through Boca's eHub. Sort the HOA question before signing any contract.

Q: Are impact windows worth it if I have shutters that work?

For pure code compliance: no, shutters are sufficient. But the math typically favors impact windows in 5–10 years because of:

15–45% wind mitigation insurance discount on the windstorm premium portion (Boca Raton average premium runs higher than the Palm Beach County average due to coastal proximity — $5,500–$7,500/year is common — so $825–$3,375/year savings)
Energy savings — laminated impact glass with low-E coating typically reduces cooling costs 8–15%
No deployment — older homeowners and snowbirds can't always be there to put up shutters
Property value — impact-rated homes sell faster and at higher prices in Boca's affluent market
Daily UV/noise/security benefits

Q: What's the permit process in Boca Raton?

The City of Boca Raton Building Division at 201 W. Palmetto Park Rd. handles all city permits. Hours: Monday, Tuesday, Thursday, Friday 8:00 AM–4:00 PM; Wednesday 8:00 AM–3:00 PM. The basic flow:

Application through Boca's eHub portal with completed forms, project details, and product approval numbers
Initial fee — typically a percentage of total permit cost upfront
Plan review — checks WBDR product approval, fastener schedule, sealed engineering for openings over a certain size
Pre-installation inspection (in some cases)
Final inspection and Certificate of Completion (Inspection 002 in Boca's system)

Note on insurance verification: Palm Beach County now handles Certificate of Insurance verification for Boca, so make sure your contractor's COI is addressed as "Palm Beach County."

Q: What does it actually cost in Boca?

Window	Installed range
Single-hung impact (vinyl)	$800–$1,400
Single-hung impact (aluminum)	$1,000–$1,600
Casement impact	$1,250–$1,900
Slider impact (6 ft)	$4,000–$6,800
Picture window impact	$1,400–$2,800

A typical 12-window Boca Raton home runs $12,000–$23,000 all-in. Coastal A1A-adjacent properties typically run 12–18% higher because of higher DP requirements and salt-rated hardware. Boca permit fees range $150–$500 depending on project scope. → Get exact pricing — 3 free quotes

Q: My insurance carrier just non-renewed me. Will impact windows fix this?

Possibly. Many Florida carriers have hardened underwriting since 2020:

Roof age limits (15 years for shingle, 20–25 for tile)
Required wind mitigation features
4-point inspection requirement on homes 20+ years old

If your carrier non-renewed citing wind exposure, impact glass + a wind-mit inspection often reopens the door — either with the same carrier (sometimes) or with a competing carrier. Boca's affluent market means carriers scrutinize coverage tightly; documented impact glass with proper permits helps significantly.

Q: How do I verify my installer is licensed?

Search FloridaContractorCheck.com by the contractor's name, business name, or license number. Look for:

Active CGC, CBC, CRC, or specialty Window/Door license
Future expiration date
No open disciplinary actions
Liability insurance + workers' comp (request the certificate of insurance directly from the contractor)

A "general handyman license," a county business tax receipt, or an "occupational license" is not a contractor license. Florida Statute § 489.127 makes unlicensed contracting a third-degree felony for repeat offenders — and a homeowner who hires an unlicensed contractor loses access to the Florida Homeowners' Construction Recovery Fund.

Boca Raton Neighborhood Considerations

Boca Beach, Boca Raton (East), Spanish River, Royal Palm Yacht & Country Club, Por la Mar — direct Atlantic exposure; highest DP requirements; engineered fastener schedules common
Boca West, St. Andrews, The Polo Club, Boca Grove, Woodfield Country Club — strict HOA architectural review; specific frame profiles and colors mandated
Mizner Park area, Old Floresta, Boca Square — historic considerations for some properties; older glazing systems
Boca Pointe, Boca Falls, Logger's Run, Saturnia, Mission Bay — large family-home developments; standard installs most common
Highland Beach (separate municipality just south of Boca) — separate building department; different permit timeline

What Inspectors Check

When the building inspector comes out for the final on a Boca window replacement (Inspection 002):

✅ Window assembly matches the approved product approval (model, glazing thickness, framing material)
✅ Fasteners match the manufacturer's installation schedule (type, length, spacing)
✅ Sub-sill flashing properly installed and integrated with weather-resistive barrier
✅ Caulking and sealing meets manufacturer specifications
✅ Window operates correctly (locks, opens, drains)
✅ All glazed openings in the project pass — no exceptions for "we'll do that one later"

For multi-family or multi-home projects, fire inspections must be performed before the final inspection, smoke detectors must be interconnected, and child safety locks are required where applicable. The Certificate of Completion is what your insurance carrier wants for wind mitigation credit. Don't accept any contractor handoff that skips this step.
