What Are the Florida Building Code Requirements for Commercial Doors?

The Florida Building Code (FBC) adopts the International Building Code (IBC) as its base code but adds Florida-specific amendments that impose additional requirements on commercial door assemblies. The most significant additions are the High Velocity Hurricane Zone (HVHZ) provisions for Miami-Dade and Broward counties, the Florida Product Approval system requiring all doors to carry either a Miami-Dade Notice of Acceptance (NOA) or a statewide Florida Product Approval (FL number), and wind-borne debris region testing standards (TAS 201, TAS 202, TAS 203) that exceed IBC baseline requirements. Fire-rated door assemblies must additionally comply with NFPA 80 as adopted by the FBC. This guide covers the code framework, testing standards, product approval pathways, and fire rating requirements that apply to commercial doors installed in Florida.

About This Guide

This guide is published by CDF Distributors, a commercial door distributor holding Florida Product Approvals. These approvals are issued through accredited testing and certification agencies recognized by the Florida Building Commission. CDF’s Florida-approved product lines cover hollow metal doors, hollow metal frames, and wood doors for both HVHZ and non-HVHZ applications. The information in this guide reflects publicly available provisions of the Florida Building Code and is intended as a reference for architects, specifiers, and contractors. Always verify requirements with the Authority Having Jurisdiction (AHJ) for your project.

How the Florida Building Code Adopts and Amends the IBC

The Florida Building Code is administered by the Florida Building Commission under the Florida Department of Business and Professional Regulation. The FBC adopts the International Building Code as its base code on a three-year cycle, but the Florida legislature and Building Commission add state-specific amendments that override or supplement IBC provisions. For commercial doors, the most consequential amendments involve wind resistance, impact testing, and the mandatory Florida Product Approval system.

The following table summarizes the key differences between the IBC baseline and the Florida-specific amendments as they apply to commercial door assemblies.

High Velocity Hurricane Zone (HVHZ) Requirements

The HVHZ encompasses all of Miami-Dade County and Broward County. These two counties have the most stringent wind and impact requirements in Florida and among the most stringent in the United States. Doors installed in the HVHZ must meet requirements that go beyond the standard FBC provisions that apply to the rest of the state.

HVHZ Door Requirements

Doors installed within the HVHZ must satisfy all of the following conditions. Failure to meet any one condition will result in rejection by the local building official.

• Miami-Dade Notice of Acceptance (NOA). Every door product installed in the HVHZ must hold a current NOA issued by Miami-Dade County. The NOA documents the specific products, configurations, and installation methods that have been tested and accepted. A statewide FL number alone is not sufficient for HVHZ installations.
• Large missile impact testing per TAS 201. The door assembly must withstand impact from a 9-pound 2x4 lumber projectile fired at 50 feet per second (34 mph). This simulates wind-borne debris during a hurricane. The test applies to any door assembly protecting an opening below 30 feet above grade.
• Cyclic wind pressure testing per TAS 203. After the impact test, the door assembly must withstand cyclic positive and negative wind pressure loading without failure. This test simulates the repeated pressure fluctuations that a door experiences during a hurricane.
• Uniform static air pressure testing per TAS 202. The door assembly must resist sustained wind pressure loads at the design pressure rating specified for the installation location.
• Design pressure ratings. The required design pressure is determined by the building’s location, height, exposure category, and the size of the door opening. HVHZ design pressures frequently exceed +/- 50 PSF and can reach +/- 80 PSF or higher for upper floors of tall buildings.

Non-HVHZ Wind Zone Requirements

Outside of Miami-Dade and Broward counties, the remainder of Florida is governed by the standard FBC wind provisions. While these areas do not require a Miami-Dade NOA, they still impose requirements that exceed the IBC baseline. The following table summarizes the non-HVHZ requirements for commercial door assemblies in Florida.

Florida’s wind-borne debris region extends along the entire coastline and covers significant portions of the peninsula. Even projects that are not in the HVHZ may still fall within the wind-borne debris region and require impact-rated door assemblies. The AHJ determines whether a specific project site falls within the wind-borne debris region.

Florida Product Approval System

The Florida Product Approval system is a mandatory certification process administered by the Florida Building Commission. Every building product that is subject to the FBC, including commercial doors, must hold a valid product approval before it can be installed in the state. There are two pathways to product approval, and the pathway determines where the product can be installed.

NOA vs. FL Number

The two product approval pathways serve different geographic scopes within Florida. The following table explains the distinction between a Miami-Dade NOA and a statewide Florida Product Approval.

A Miami-Dade NOA is accepted statewide because it meets or exceeds the testing requirements for the standard Florida Product Approval. However, a statewide FL number is not accepted in the HVHZ because the HVHZ requires the additional testing and review process administered by Miami-Dade County.

Design Pressure Ratings for Florida Doors

Design pressure (DP) is the wind load, measured in pounds per square foot (PSF), that a door assembly must resist without failure. The FBC requires that every exterior door assembly meet or exceed the design pressure calculated for its specific installation location. Design pressure is determined by wind speed, building height, exposure category, and the size of the opening.

The positive value represents inward pressure (wind pushing against the door), and the negative value represents outward pressure (suction pulling the door away from the frame). Both conditions must be tested. The design professional of record calculates the required DP for each opening, and the specified door assembly must have a tested DP rating that meets or exceeds that value.

Impact Testing Standards: TAS 201, TAS 202, TAS 203

The Florida Building Code references three Testing Application Standards (TAS) that govern how door assemblies are tested for wind and impact resistance. These standards were developed by the Florida Building Commission and are specific to Florida. The following sections describe each standard and its role in the product approval process.

TAS 201: Large Missile Impact Test

TAS 201 tests a door assembly’s ability to resist penetration by wind-borne debris. The test involves firing a 9-pound 2x4 lumber projectile at the door assembly at a specified velocity. For the large missile test, the projectile speed is 50 feet per second (34 mph). The projectile is aimed at the most vulnerable points of the assembly, including the center of the door panel, near the lock, and near the edges. After impact, the assembly must remain intact with no through-penetration that would allow wind and rain to enter the building.

TAS 202: Uniform Static Air Pressure Test

TAS 202 tests the structural capacity of a door assembly under sustained wind pressure. The door is mounted in a test chamber, and air pressure is applied uniformly across the entire surface to simulate wind loading. The test applies both positive pressure (inward) and negative pressure (outward) to the assembly. The door must resist the design pressure without structural failure, excessive deflection, or loss of operability.

TAS 203: Cyclic Wind Pressure Test

TAS 203 tests a door assembly’s ability to withstand repeated pressure cycling that simulates the fluctuating wind loads during a hurricane. The test is performed after impact testing (TAS 201) on the same specimen. The assembly is subjected to thousands of pressure cycles at increasing loads. This test is critical because it verifies that a door assembly that has already absorbed an impact can continue to resist wind pressure throughout the duration of a storm.

Wind-Borne Debris Regions in Florida

The FBC defines wind-borne debris regions as areas where exterior building components, including doors, must be impact-rated. Understanding whether a project falls within a wind-borne debris region is critical for specifying the correct door assembly. The following criteria determine wind-borne debris region boundaries.

• Within 1 mile of the coast where the basic wind speed is 130 mph or greater (per the FBC wind speed map)
• Anywhere in Florida where the basic wind speed is 140 mph or greater, regardless of distance from the coast
• All of the HVHZ (Miami-Dade and Broward counties) regardless of distance from the coast

In wind-borne debris regions, exterior door assemblies protecting openings below 30 feet above grade must pass the large missile impact test (TAS 201 at 50 fps). Openings at or above 30 feet must pass the small missile impact test (TAS 201 at 50 fps with smaller projectiles, or as specified by the design professional). Interior doors separating conditioned space from unconditioned space may also require impact ratings depending on the building’s wind design.

NFPA 80 Compliance in Florida

NFPA 80 governs the installation, inspection, testing, and maintenance of fire door assemblies. The FBC adopts NFPA 80 and the AHJ enforces it. Key NFPA 80 requirements that apply in Florida include the following.

• Labeling. All fire door components must bear labels from an accredited testing laboratory (UL, Intertek/WHI, or equivalent).
• Annual inspection. NFPA 80 requires that fire door assemblies be inspected and tested annually. The FBC reinforces this requirement through its fire prevention code provisions.
• Clearances. NFPA 80 specifies maximum clearances between the door and frame: 1/8 inch at the hinge edge and top, 1/8 inch at the strike edge (3/16 inch for pairs without an astragal), and 3/4 inch maximum at the bottom.
• Self-closing and self-latching. Fire doors must close and latch automatically without human intervention. Door closers and latching hardware are mandatory on all fire-rated openings.
• Field modifications prohibited. Fire door assemblies cannot be modified in the field (e.g., cutting, adding hardware holes, removing labels) without authorization from the original listing agency.

Specifying Doors for Florida Projects

When specifying commercial doors for a Florida project, the following checklist ensures compliance with the FBC. Each item must be addressed during the design and submittal phase.

1. Determine whether the project is in the HVHZ (Miami-Dade or Broward County) or in the standard FBC jurisdiction.
2. Determine whether the project is in a wind-borne debris region by checking the FBC wind speed map and the distance from the coastline.
3. Calculate the required design pressure (DP) for each exterior opening per ASCE 7 and the FBC wind speed maps.
4. Verify that the specified door assembly holds the appropriate product approval: NOA for HVHZ installations, FL number for non-HVHZ installations.
5. Confirm that the product approval covers the specific configuration (door size, frame type, hardware, glazing) being specified.
6. For fire-rated openings, verify that all components (door, frame, hardware, glass, louvers) carry matching fire labels at the required rating level.
7. Include the FL number or NOA number in the project specifications and submittal documents for building official review.
8. For HVHZ projects, include the Miami-Dade NOA and all referenced installation details in the permit application.
