Miami-Dade Building Code Changes

Florida's new state code begins December 31, 2026, and Miami-Dade portal filings sent after 4:00 p.m. on December 30 must follow it.
Projects needing permits include expansions, major renovations, structural work, some window and door changes, electrical or plumbing installations, and many roof or hurricane upgrades.
The shift does not make all repairs subject to permits, and incomplete applications submitted early still may require revisions before approval by authorities.
In Miami-Dade, roof projects deserve extra attention because High Velocity Hurricane Zone rules, updated underlayment standards, and product approvals can affect materials.
Before hiring, ask which agency will issue the permit, which code edition applies, whether products are approved, and what inspections and revisions may follow.
