Why Palm Beach County Requires a Permit
Palm Beach County enforces Chapter 16 of the Florida Building Code for wind-load design, which means every window opening must be engineered to resist the pressures generated by the design wind speeds in your specific location. Coastal parcels in Palm Beach County carry design pressures of 170+ mph; inland parcels are still subject to 160+ mph design speeds — both well above what non-impact glazing can handle.
The Palm Beach County Building Department administers permits for unincorporated areas. If your home sits within a city's corporate limits — West Palm Beach, Boca Raton, Boynton Beach, Delray Beach, Jupiter, Wellington, or Palm Beach Gardens — that city's building department is your permitting authority, though it enforces the same Florida Building Code standards. City-level review typically runs 14–25 business days; unincorporated county review runs 21–35 business days.
For impact windows installation across all South Florida counties, the governing framework is consistent — but Palm Beach County's WBDR-only (non-HVHZ) status creates one meaningful advantage: Florida Product Approval numbers (FL #) are accepted in addition to Miami-Dade NOAs, giving contractors and homeowners more product options than are available further south.
