Florida’s 9th Edition Building Code takes effect Dec. 31, 2026, and it contains some significant changes that will affect bids for new jobs, material takeoff and, potentially, timelines and expenses for jobs you’ve already won.
The building code is updated every three years. While design professionals will need to incorporate the new code into their work, for the construction side of the business it’s a planning issue. Permits issued before Dec. 31 are generally grandfathered under the current 8th Edition — which means the next six months offer an important opportunity to schedule the projects you’ll source and build under familiar rules, and decide which ones will be subject to the new rules.
Biggest Changes for Builders
The 9th Edition brings at least two changes with direct consequences for contractors — one affecting what products you can use and where, and one affecting the building envelope.
The first change — a provision still moving through the Florida Legislature (HB 911/SB 1218) — is expansion of the requirement for impact-resistant windows and doors in High Velocity Hurricane Zones (HVHZ). It would apply to multistory R-1 and R-2 residential structures.
Under the 8th Edition, HVHZ areas were limited essentially to Miami-Dade and Broward counties, according to Safeguard, a provider of impact-resistant windows and doors. In the 9th Edition, the requirement would be expanded to all new construction within five miles of tidal waters.
“That change is driven by ASCE 7-22 wind-hazard mapping. The mapping reflects updated storm-track data from the last 30 years of Atlantic hurricane seasons. In practical terms, coastal communities that previously designed to 130 or 140 mph criteria may now need glazing rated to 160 mph or higher,” Safeguard’s blog notes, overlooking the fact that the change has yet to be finalized. “The 9th Edition [would be] one of the most consequential envelope changes since Hurricane Andrew forced the original HVHZ into existence.”
For builders and contractors, the change would mean an increase in the number of projects that will require impact-rated windows, doors and other glazing. These items already carry longer lead times than standard products and systems. As demand increases for these materials, contractors who wait until a project is permitted to have the sourcing conversation may find they’re competing for a tighter supply — meaning higher prices and/or a longer wait.
The second change is alignment of the energy code with 2024 IECC, notes the blog of St. Petersburg-based Revolution Contractors. While the specifics are still being finalized, the 9th Edition will emphasize better-insulated building envelopes and more efficient mechanical systems.
For contractors who are pre-purchasing insulation, HVAC equipment or window packages for projects that might not break ground until next year, it’s worth confirming which code the project will be permitted under before the order goes in.
Product Approvals: Verify Before You Order
Florida’s product approval system requires that windows, doors, roofing materials and other regulated products carry a Florida Product Approval valid under the applicable code edition. When the 9th Edition takes effect, products will need to comply with the updated requirements — and not every product currently on the market will have updated approvals in place on Day One.
This is the kind of gap that shows up mid-project when a shipment arrives and the inspector wants to see paperwork that doesn’t exist yet. The conversation to have with your supplier before the deadline is simple: For any project that will be permitted under the 9th Edition, confirm that the products you’re specifying will carry valid Florida Product Approvals. It’s an easier conversation to have in advance than at the jobsite.
The Homeowne Insurance Upside
There’s a financial case to be made for building to the 9th Edition standard — even before it’s required. Construction that meets the hardened-building criteria — impact-rated glazing, sealed roof decks, secondary water barriers — qualifies for wind mitigation credits of up to 45% on homeowners insurance in Florida, according to Tampa-based Mesa Insurance.
For clients weighing the added cost of impact glass or a secondary water barrier on a project that could still be permitted under the 8th Edition, the insurance savings are worth considering. A structure that qualifies for mitigation credits carries lower ongoing insurance costs — which can offset some or all of the upfront premium for the upgraded products. Builders risk policies in Florida run between $1.20 and $4.50 per $100 of construction value, with coastal projects at the high end; hardened construction can shift that calculus meaningfully at the permanent policy stage.
What To Do Now
Here are some practical steps to take now:
-
Review your pipeline for projects that might not be permitted until 2027 and build code-version language into those bids.
-
For any project within five miles of tidal water that you’re planning to permit under the 8th Edition, make sure the timeline is realistic. If the change is finalized by the Legislature, a permit application submitted late in the year may not be approved in time to allow the 8th Edition standards.
-
Start supplier conversations now on impact-rated windows and doors. Lead times aren’t going to get shorter as more projects move into the expanded impact zone, and the contractors who’ve already had the conversation will be in better shape than the ones who haven’t.
