Florida updates its building code on a roughly three-year cycle, and the next update is a big one. The 9th Edition of the Florida Building Code takes effect December 31, 2026, replacing the current 8th Edition (2023). For any project still moving through design, the date on the calendar matters as much as the drawings on the table.
What’s Changing
The 9th Edition brings substantial updates across three areas:
Wind loads. The code adopts ASCE 7-22 for wind load calculations, replacing ASCE 7-16. It also expands the 160 mph impact resistant envelope to new construction within five miles of tidal water, and multistory hotel and apartment or condo buildings of two or more stories will need to meet expanded coastal opening protection requirements.
Energy performance. Glazing U-factor and Solar Heat Gain Coefficient thresholds move closer to the 2024 IECC. Some product specs that are compliant today will need to be upgraded to meet the new standard. On the commercial side, if code equivalency is the target, the energy code will need to catch up to the 2024 IECC, which may bring in energy related changes that the 2023 code left out.
Flood provisions. The 8th Edition references ASCE 24-14. The 9th Edition is expected to reference the newer ASCE 24-24, which expands the regulated flood hazard area and raises requirements for finished floor elevation and flood resistant materials below the design flood elevation.
Product approvals (NOAs) on building materials will also need revalidation under the new code, which adds another round of engineering and documentation work.
The Date That Actually Matters
Here’s the part that gets missed: what determines which code a project falls under isn’t the design date or the construction date. It’s the date the permit application is submitted for review.
A permit application submitted for review before December 31, 2026 generally proceeds under the current 8th Edition. An application submitted on or after that date proceeds under the new, stricter 9th Edition. Any project not yet submitted for review risks falling under the new code, regardless of how far along the design work already is.
Not Ready for a Full Submission? Submit for a Process Number Anyway
Clients don’t need a 100% complete construction document set to get into the queue. If a project is at 80% CD or further, it can be submitted for a process number now. Package will be reviewed by staff and comments will need to be addressed but this secures a place under the current code while the remaining design work is finished.
Who Should Be Paying Attention
Commercial and multifamily developers face materially higher compliance costs under the new code: stricter wind design, expanded flood and freeboard requirements, and tighter energy performance standards on glazing and HVAC systems.
Coastal and flood zone projects see the biggest jump. ASCE 24-24 raises the bar significantly on flood resistant construction and on where equipment can be placed relative to the design flood elevation.
The Bottom Line
This is a real, dated deadline, not a hypothetical one. Projects that submit for review, even at the process number stage, before December 31, 2026 lock in the current code. Projects that wait risk redesign, added engineering, and higher costs under the 9th Edition.
If you have a Florida project in design right now, the question worth asking today is simple: is it far enough along to submit for a process number before the end of the year?
