Sheds, carports, pergolas, and screen enclosures are common accessory projects, and in South Florida many of them require engineered plans to permit, because the structure has to resist wind uplift and pressure for your wind zone.
This guide covers the usual triggers. The requirement depends on size, type, and jurisdiction, which we confirm for your project.
Sheds and accessory structures
Above a certain size, jurisdictions generally require engineered anchorage and tie-down for sheds and similar structures, checked against verified hardware capacity, so the structure resists uplift and overturning.
Screen enclosures
Screen enclosures typically require engineered members and connections showing the aluminum frame resists wind pressure on the screen walls and roof, per the Florida Building Code and aluminum framing standards.
Questions
Is there a size below which I don't need engineering?
Many jurisdictions exempt very small accessory structures, but the threshold varies and HVHZ rules can change it. We confirm whether your specific shed, carport, or enclosure needs sealed engineering before starting.
