Step 3: Add Your Openings

Step 5: Submit with Your Permit Application

Attach the calculation sheet to your building permit application. Verify each product's Florida Product Approval (FL#) or Miami-Dade NOA meets the calculated design pressures.

Zone 4 vs Zone 5

Zone 4 (interior wall) applies to windows and doors away from building corners — the correct zone for most openings. Zone 5 (corner zone) applies when any part of the opening is within distance 'a' of a building corner. Distance 'a' equals 10% of the building's shortest side, with a minimum of 3 ft. For a 30 ft wide building, a = 3 ft.
