Hurricane-Rated Commercial Build-Outs in South Florida: What to Ask Your GC

South Florida commercial construction is governed by some of the most stringent wind load and impact resistance requirements in the country. A commercial build-out in Palm Beach or Broward County must comply with the Florida Building Code’s wind provisions for its specific geographic location – and for coastal and barrier island properties, those requirements are substantial. Understanding what is required – and asking the right questions before you hire a GC – protects your investment and your tenants.

Why South Florida’s Hurricane Code Requirements Are Unique

Florida Building Code wind speed requirements are mapped by location. In Palm Beach County, design wind speeds typically range from 140 to 175+ mph depending on proximity to the coast. Broward County has similar requirements. These are not aspirational targets – they are minimum legal requirements that every new commercial build-out must meet.

For interior commercial tenant improvements, hurricane compliance usually focuses on:

• Impact-rated windows and storefronts (or hurricane shutters with engineering documentation)
• Roof-to-wall connections and roof assembly integrity (if the build-out involves roofing)
• Exterior doors meeting impact and pressure requirements
• Structural attachments for wall framing, mechanical equipment, and roof-mounted HVAC units
• Proper product approvals – Florida Product Approval (FPA) or Miami-Dade NOA – for all impact-rated assemblies

Florida Product Approval: What It Means for Your Build-Out

Every impact-resistant product installed in a Florida commercial building – windows, doors, storefronts, curtain walls, skylights – must carry a valid Florida Product Approval (FPA) number or a Miami-Dade Notice of Acceptance (NOA). These approvals confirm that the product has been tested to meet the wind speed and impact requirements for its intended use.

Your GC must specify, order, and install products with current approvals. Expired approvals or unapproved substitutions are a red flag during inspection and can require removal and replacement. Ask your GC for product approval documentation before materials are ordered.

Questions to Ask Your GC About Hurricane Compliance

Do not assume your GC is managing wind code compliance – ask directly. Here are the key questions:

1. Are all proposed window and door products Florida Product Approved or NOA-certified for our wind zone? Ask to see the approval numbers.
2. Has a Florida-licensed engineer reviewed and stamped the plans for wind loading? This is required for commercial projects above a certain size and for any structural work.
3. How are rooftop HVAC units anchored? Improperly secured rooftop equipment is a common failure point in hurricanes. Equipment must be anchored per engineer-reviewed calculations.
4. What is the installation sequence for impact windows and storefronts, and when do inspections occur? Impact glazing must be inspected before it is covered by drywall or casing.
5. Is there an existing hurricane protection system on the building, and does our build-out require modifications? Some buildings have accordion shutters or panels. Changes to the envelope may require landlord approval and engineering review.
6. How are penetrations through the building envelope detailed? HVAC, plumbing, electrical, and mechanical penetrations through exterior walls must be sealed per Florida Building Code requirements.

Existing Buildings: What the Code Triggers

For commercial tenant improvements in existing buildings, the Florida Building Code’s “substantial improvement” rules are important. Generally, if the cost of improvements exceeds a threshold percentage of the building’s value, more extensive code compliance upgrades may be triggered – including envelope improvements that go beyond your specific tenant space. Your GC and architect should evaluate this threshold before finalizing scope.

In older commercial buildings in Boynton Beach, Delray Beach, and West Palm Beach that were built before the Florida Building Code was adopted after Hurricane Andrew (1992), significant non-compliant conditions may exist in the building envelope. These do not always have to be corrected as part of a tenant improvement, but understanding the existing conditions protects you from liability and from misrepresentation in your lease.

Hurricane Season Timing and Your Construction Schedule

Hurricane season runs June 1 through November 30. If your project has open-air phases – roofing, storefront replacement, or exterior wall work – those phases are higher risk during hurricane season. An experienced South Florida GC will sequence work to minimize exposure and have a clear plan for securing the job site before a storm event. Ask about the site security and weather preparation protocol before construction begins.

Projects with exterior envelope work should have specific provisions in the contract for storm prep – who is responsible, what materials are secured and how, and what happens to the schedule if a named storm requires a mandatory evacuation. These are not hypothetical scenarios in South Florida – they are planning requirements.

Insurance Considerations for Commercial Build-Outs

Builder’s risk insurance during construction and your tenant’s property insurance after occupancy both depend on the wind resistance rating of your improvements. Improperly installed impact products or non-compliant glazing can affect insurance coverage in the event of a loss. Verify with your insurance broker that the construction scope is properly documented and that policy requirements are met.

Your GC should carry commercial general liability insurance and workers’ compensation insurance with coverage limits appropriate for the project size. Ask for certificates of insurance before work begins and confirm your property is listed as an additional insured.

Start Your Build-Out the Right Way

Hurricane code compliance is not a line item you cut to save money. The fines, inspection failures, and liability exposure from non-compliant commercial construction in South Florida far exceed the cost of doing it right the first time.
