A New Florida Building Code. Your Application Date Decides Which One Applies.

The application date matters more than the start of construction.

Florida updates its building and fire codes every three years. The 9th Edition (2026) of the Florida Building Code is published and, according to Pineland Engineering, becomes effective December 31, 2026. Until then, the 8th Edition (2023) remains the code for permit applications. FORUM describes the new code as applying to projects submitted for permit on or after January 1, 2027.

Under Section 553.73 of the Florida Statutes, the code in effect on the permit application date generally governs the permitted work for the life of that permit and its extensions. A project designed in 2026 does not automatically fall under the new edition, and a project that breaks ground in 2027 does not automatically need a redesign. What counts is when the application goes in and how the building department handles intake.

Miami Dade: watch the 4 p.m. cutoff on December 30.

Miami Dade has published a local notice stating that the 9th Edition becomes effective December 31, 2026, and that online submissions after 4 p.m. on December 30 are treated as 9th Edition submissions. If you plan to file in Miami Dade under the current code, that afternoon matters. Pineland notes this is a local rule, not a statewide portal cutoff.

Orlando and Central Florida. Do not assume the same cutoff. Ask the building department how its portal treats submissions near the transition, how resubmittals are handled, and whether phased permits change the answer.

Smoke protection at elevator openings in buildings of four or more stories.

FORUM calls this the most notable change of the cycle. To limit smoke movement through elevator shafts, the code now requires added protection at elevator openings located within corridors of buildings four or more stories tall. FORUM lists three ways to comply:

An enclosed elevator lobby with doors on either side, which may be held open magnetically and released by the fire alarm system.
A door directly outside each hoistway opening.
A recessed, concealed smoke curtain directly outside each hoistway opening.

The requirement does not apply where elevators open directly to the exterior. Protection can also be omitted at the level of exit discharge, typically the ground floor, when the building has a full NFPA 13 sprinkler system rather than NFPA 13R. Where it applies, FORUM expects it to affect both design and construction cost.

Other changes worth a look.

FORUM also points to clarified fire rating continuity where floor assemblies meet exterior walls, and clearer rules on when an occupied roof can be served by a single exit. Pineland notes that the Florida Building Commission analyses cover residential flood provisions, including new definitions for substantial damage and substantial improvement, and energy changes such as removal of the REScheck compliance option for residential work.

Not every 2024 model code change was adopted in Florida, so a national summary is not a reliable checklist. The governing code volume and the local building department decide.

What owners should do now.

Set the target application date before drawings are finalized.
Keep every discipline on one edition: architectural, structural, MEP, energy and flood drawings.
Review elevator options early if the building has four or more stories and elevators opening into corridors.
Confirm portal cutoffs and resubmittal rules with the building department.
Record the submittal date and code basis in the project file.
