A Quick Guide to Palm Beach County Window Replacement Code

Living in Florida is unlike anywhere else in the United States. With its beautiful beaches, thrilling theme parks, dense national parks, and lively orange orchards, the State boasts an array of attractions.

However, its location along the volatile Atlantic Ocean means it's been on the receiving end of more hurricanes than any other state. Consequently, the prevalence of impact windows, especially in places like Palm Beach County, is not surprising. If you reside in Miami-Dade County, the looming danger of hurricanes might have pushed you to consider installing hurricane-impact windows.

However, before leaping into the installation process, it's crucial to understand the building regulations in Palm Beach. Here's a rundown on what you need to know:


The Florida Building Code

The Florida Building Code outlines precise standards for construction methodologies and materials. No matter where you're located in Florida, any modifications to your structure necessitate proper authorization. As articulated in section 104.1.1 of the Florida Building Code:

"Any individual, agent, or contractor aiming to construct, expand, modify, repair, move, or dismantle a building or its occupancy, or modify any electrical, gas, or plumbing system regulated by technical codes, must first seek approval from the building official and acquire the essential permit."

However, the code recognizes that certain areas are more affected than others when it comes to hurricanes.


Wind-Borne Debris Zones

As the name suggests, these maps show the kinds of wind speeds you can expect during the Atlantic Hurricane Season. They are usually split into four categories:

  • Wind Zone 1 – with expected wind speeds of 100 to 119 mph
  • Wind Zone 2 – ranging from 120 to 129 mph
  • Wind Zone 3 – accounting for speeds of 130 to 139 mph, typically within a mile of the coastline
  • Wind Zone 4 or the High-Velocity Hurricane Zone (HVHZ) – where wind speeds can surpass 140 mph

Regions designated as HVHZs, such as Palm Beach or Broward counties, adhere to more rigorous building codes compared to areas like Wind Zone 1 or 2. In HVHZs, structures must ensure the entire exterior, including windows and doors, meets wind-resistant design standards verified through laboratory testing.

Since Hurricane Michael hit the panhandle and caused devastation to the northern region, there is speculation that these standards should be made consistent across the State.

HVHZs and Impact Window Testing

To acquire a permit for impact window installation in HVHZs, you must provide relevant information about those windows. This includes the manufacturer's name, approval numbers, and appropriate materials.

Impact window testing in HVHZs comprises The Large Missile Debris Test and the Small Missile Debris Test.


Large Missile Debris Testing

Windows positioned 30 feet or below from the ground are evaluated under the Large-Missile Debris Test. Windows must withstand a 9-pound 2×4 lumber missile at 34 mph, followed by 9,000 cycles of wind testing to pass this test.


Small Missile Debris Testing

On the other hand, windows elevated 30 feet or above are assessed through the Small-Missile Debris Test. Windows must repel ten ball bearings traveling at 50 mph, then undergo wind tests for 9,000 cycles to meet this criteria.

The Importance of Impact Windows in Coastal Regions

Let's take a moment to address a pressing concern for all coastal dwellers - the sheer power of Mother Nature. If you live near the coast, you've likely witnessed the forceful gusts and turbulent weather patterns typical of hurricane season. That's why it's crucial to understand the significance of impact windows in coastal areas.

Impact-resistant windows are designed to withstand the high winds and flying debris commonly associated with hurricanes. Without these windows, homes in coastal regions are at risk of shattered glass, water damage, and the potential compromise of a home's structural integrity during a storm.
