Carport Design — Florida Architect

Designing a carport in Florida necessitates a comprehensive understanding of the Florida Building Code (FBC), particularly its provisions for open-sided structures and the critical aspect of wind load design.

Unlike fully enclosed buildings, carports, by their very nature, are considered open structures, which significantly impacts their wind load calculations. The FBC, 7th Edition (2020), which largely adopts and modifies the International Building Code (IBC) and references ASCE 7-16, 'Minimum Design Loads and Associated Criteria for Buildings and Other Structures,' is the governing document.

For carports, the primary concern is uplift and lateral wind forces.

ASCE 7-16, Chapter 27, specifically addresses 'Wind Loads on Open Buildings and Other Structures.' This chapter defines an 'open building' as a structure where at least 80% of the perimeter walls are permanently open. Carports typically fall under this classification. The design wind speed for a given location in Florida is determined from ASCE 7-16 Figures 26.5-1A, 26.5-1B, and 26.5-1C, which provide 3-second gust basic wind speeds for Risk Category II buildings. For carports, which are generally Risk Category I or II structures, these wind speeds are paramount. Furthermore, the FBC, Section 1609.1.1, mandates that buildings and structures, including carports, shall be designed for wind loads in accordance with ASCE 7. This includes consideration of exposure categories (B, C, or D), topographic factors, and enclosure classifications.

Crucially, ASCE 7-16, Section 27.3, provides specific pressure coefficients for open buildings, which differ substantially from those for enclosed or partially enclosed structures.

These coefficients account for the internal pressures that can build up within an open structure, leading to significant uplift forces on the roof. The FBC also has specific requirements for anchorage and connections to resist these uplift forces. For instance, FBC Section 1604.8.3 requires that the design of connections and anchorage for structural members be capable of resisting the design loads, including wind uplift. This often translates to robust foundation systems, such as concrete footings with embedded anchor bolts, and strong connections between columns, beams, and roof framing.

Beyond wind loads, the FBC also addresses other structural considerations.

For example, FBC Section 1607.1 specifies minimum uniformly distributed live loads, though for carports, these are typically minimal compared to wind loads. Dead loads, comprising the weight of the structure itself, must also be accurately calculated (FBC Section 1606). Furthermore, material specifications and construction methods must comply with FBC Chapters 21-23 for masonry, concrete, and wood, respectively, or FBC Chapter 22 for steel. Any pre-engineered metal carport systems must possess a Florida Product Approval, as mandated by Florida Statute 553.842 and FBC Section 1601.3.1, ensuring they have been tested and certified to meet Florida's stringent wind load and structural integrity requirements. Pineland Engineering meticulously applies these code provisions, ensuring every carport design is not only compliant but also engineered for maximum resilience against Florida's challenging environmental conditions.

Obtaining a permit for a carport in Florida is a multi-faceted process that requires careful attention to detail and adherence to local and state regulations.

The process typically begins with the submission of a comprehensive permit application package to the local building department (e.g., county or city). This package must demonstrate that the proposed carport design complies with all applicable sections of the Florida Building Code (FBC) and local zoning ordinances.

* Foundation Plan: Detailing footing sizes, reinforcement, and anchorage.

* Framing Plans: Showing roof framing, column sizes, beam sizes, and connection details. * Elevations: Depicting the carport from all sides, including heights and finishes. * Sections: Illustrating construction details and material assemblies. * Details: Specific connection details, flashing, and other critical components. * Wind Load Calculations: A separate sheet or section within the drawings explicitly detailing the design wind pressures, uplift forces, and lateral forces, referencing ASCE 7-16 and FBC Section 1609. * Material Specifications: Listing all materials to be used, including their product approval numbers if applicable (e.g., for pre-engineered metal carport components).

Once submitted, the permit application undergoes a plan review process.

Building department staff, including plans examiners, review the drawings and documents for compliance with the FBC, local zoning, and other applicable codes. The timeline for plan review can vary significantly depending on the jurisdiction and the complexity of the project, ranging from a few days to several weeks. During this phase, the building department may issue 'comments' or 'corrections' requiring revisions to the plans. Pineland Engineering proactively addresses these comments, ensuring a smooth and efficient path to permit approval. Our expertise minimizes delays, helping you get your carport project off the ground faster and without costly rework.

Choosing Pineland Engineering for your carport design and permitting needs offers a distinct and invaluable advantage in Florida: our dual licensure as both a structural engineering firm (PE 39202) and an architectural firm (AR102594).

This integrated approach streamlines the entire project lifecycle, from initial concept to final permit approval, providing unparalleled efficiency, cost-effectiveness, and design integrity.

In Florida, many carport projects, especially those of significant size or complexity, require the sealed drawings of both a licensed architect and a licensed structural engineer.

Florida Statute 471.003 defines the practice of engineering, while Florida Statute 481.219 defines the practice of architecture. While there can be some overlap, particularly in structural aspects, each profession brings a unique and essential perspective. An architect focuses on aesthetics, functionality, spatial relationships, and compliance with zoning and accessibility codes (where applicable). A structural engineer, on the other hand, is solely focused on the structural integrity, safety, and resilience of the building against all applicable loads, most critically wind loads in Florida, as per FBC Section 1609 and ASCE 7-16.

When you engage separate firms for architecture and structural engineering, you often encounter communication gaps, potential design conflicts, and increased project timelines.

The architect might design a visually appealing structure that proves difficult or overly expensive to engineer for Florida's wind loads, or the engineer might propose a structurally sound solution that compromises the architectural vision. This back-and-forth can lead to delays, redesign costs, and frustration.

Pineland Engineering eliminates these challenges. Our in-house team of architects and structural engineers collaborates seamlessly from day one.

The architectural design is inherently informed by structural feasibility and code compliance, while the structural engineering is integrated with the aesthetic and functional goals. This means:
