How Many Windows Can You Replace Before Code Requires Impact Glass in Florida?

The trigger is not really about window count alone. It is about how much of the home is being altered, where the home sits, and whether the work crosses the threshold that brings current code into play. In Redington Beach, that question matters because coastal wind and debris exposure can change the rules fast.

The 25% Rule And Why It Matters In Redington Beach

Florida homeowners usually hear about the "25% rule" when they start replacing windows, doors, or other openings.

What counts is the scope of the work, not a casual tally of frames. One large picture window can matter more than several small ones.

If the project stays under the threshold and the existing opening does not otherwise require impact protection, standard code-compliant windows may still be allowed, subject to local approval.

That is the point where a straight glass swap can turn into a bigger hurricane upgrade.

How To Decide If You Need Impact Windows Now

Once a project starts approaching the code threshold, the next decision is whether to use impact windows, shutters, or a mix of products.

For Redington Beach owners, the safest approach is to treat every replacement as a code question first and a style choice second.
