Florida updates its building code every three years. The 9th Edition is scheduled to take effect December 31, 2026, replacing the 8th Edition that has governed construction since the end of 2023.
For most homeowners this is background noise. For anyone planning a Palm Beach County project that will permit in the next several months, the timing is a real decision.
The Short Answer
The Florida Building Code 9th Edition is scheduled to take effect December 31, 2026, replacing the 8th Edition that has been in force since December 31, 2023. Permits applied for and issued before the effective date are generally processed under the 8th Edition. Projects permitted after it fall under the 9th Edition, which updates wind load standards, energy requirements, roofing provisions, and flood related design. If you are planning a Palm Beach County project for late 2026 or 2027, the permit timing is worth deciding deliberately.
The basic rule
A permit applied for and issued before the effective date is generally processed under the 8th Edition for the life of that permit. A project permitted after it falls under the 9th Edition.
Applications that are in process at the cutoff sit in a gray area handled by local jurisdiction policy. Delray Beach, Boca Raton, West Palm Beach, and unincorporated Palm Beach County can each handle that transition slightly differently, so this is a question for your specific building department rather than a general assumption.
What is changing
The 9th Edition is built on the 2024 International Codes and carries updates across several areas that matter for residential work in South Florida:
**Wind and structural.** Updated load standards and revised design provisions. On coastal parcels this touches structural design and opening protection requirements.
**Energy.** Movement toward the more recent international energy code, which affects envelope, insulation, and equipment specifications.
**Roofing.** Provisions around recovery versus full replacement are being revised, including relaxation of the longstanding rule that pushed many partial roof projects into full tear offs. For some reroof scenarios this reduces cost.
**Flood and site.** Updated flood related design provisions and stormwater requirements that matter on low lying and coastal parcels.
Some of these add cost. Some reduce it. The net effect is project specific, which is why the answer to whether you should rush a permit is not automatic.
What this means for a project in design right now
If you are in design today with a target of permitting this fall, have this conversation with your builder and architect now, not in November.
**Ask three questions:**
- Where do the drawings realistically stand, and can a complete set be submitted with time to be issued before the cutoff?
- For this specific project, which edition produces a better outcome on cost and design?
- What is the local building department's stated policy for applications in process at the transition?
The wrong move is submitting an incomplete set to beat a date. An incomplete submittal costs a full review cycle, and a permit applied for but not issued may not deliver the grandfathering you were counting on. Complete drawings are the fastest path under either edition. Our guide to pre construction covers what a complete set actually requires.
What this means for a project starting in 2027
Nothing to rush. Design to the 9th Edition and budget accordingly. Your design team will be working under it as standard by then.
The one thing worth doing early is confirming product approvals. Windows, doors, and roofing assemblies all carry approvals tied to code provisions, and product availability under a new edition takes time to settle. Locking the window and door package early is good practice regardless, and it is better practice in a transition year. Our guide to impact windows and doors in Palm Beach County covers the specification and lead time issues.
A note on how to read code coverage
Code transitions generate a lot of confident writing, some of it wrong. Two guardrails:
The Florida Building Commission and floridabuilding.org are the authoritative source for the adopted text and effective dates. Everything else, including this article, is a summary.
Your local building department determines how the transition is applied to your permit. Their answer is the one that governs your project.

Review My Permit TimingWe are building through this transition on active jobs and pricing projects on both sides of it. For most of our clients the honest answer has been that the code edition is a smaller variable than lot conditions, design decisions, and selection timing.
But if your project is close to the line, it is worth ten minutes to decide deliberately rather than letting the calendar decide for you.

Frequently Asked Questions
When does the Florida Building Code 9th Edition take effect?
It is scheduled to take effect December 31, 2026, replacing the 8th Edition that has been in force since December 31, 2023. Florida updates the code on a three year cycle. Confirm the final adopted dates with floridabuilding.org and with your local building department, since local interpretation of transition rules can vary.
Will my project be grandfathered under the current code?
Generally, a permit applied for and issued before the effective date is processed under the 8th Edition for the duration of that permit. Applications in process at the cutoff are handled according to local jurisdiction policy, so confirm with the specific building department rather than assuming.
Does the new code make building more expensive?
Some provisions add cost and some reduce it. Updated wind load and energy provisions can raise structural and envelope costs, while changes to roofing provisions such as partial roof recovery can reduce cost on certain reroof projects. The net effect depends on the specific project.
Should I rush to permit before December 31?
Only if the drawings are genuinely ready. Submitting an incomplete set to beat a deadline usually costs more in review cycles than it saves, and a permit that is applied for but not issued may not get you what you were hoping for. Decide this with your design team based on where the drawings actually stand.
Does this affect renovations or only new construction?
It affects permitted work generally, including renovations, additions, and reroofs, though the specific provisions that apply depend on the scope. Routine maintenance that does not require a permit is not affected.
