Quick Answer
For a Florida building permit, the required drawings typically include architectural, structural, mechanical, electrical, and plumbing plans, along with a site plan and energy calculations. The specific submittals depend on the project's scope and complexity, as outlined in the Florida Building Code (FBC 2023) and local amendments. For instance, structural drawings must adhere to ASCE 7-22 for load determination, and often require sealed plans from a Florida-licensed engineer or architect for new construction or significant alterations. These drawings ensure compliance with safety and performance standards. For expert guidance on your specific project's permit drawing requirements, contact Pineland Engineering at (239) 233-5133.
One of the most common reasons Florida permit applications are rejected or delayed is incomplete construction documents. Every Florida building department requires a specific set of drawings and documents before a permit can be issued, and the requirements vary by project type, scope, and jurisdiction. This guide explains what drawings are typically required for residential and commercial permit applications in Florida, and what each document must contain.
The Florida Building Code (FBC) sets minimum requirements for construction documents, but individual building departments may require additional information. Always check with your local building department for jurisdiction-specific requirements before submitting your permit application.
Pineland Engineering prepares complete permit sets for projects throughout Florida — from simple residential additions to complex commercial buildings. We know what each building department requires and how to prepare documents that pass plan review with minimal comments.,,
Site Plan Requirements
A site plan (also called a plot plan or survey) is required for virtually all permit applications in Florida. The site plan must show the property boundaries and dimensions; the location of all existing and proposed structures on the lot; setbacks from property lines, easements, and rights-of-way; the location of utilities (water, sewer, electric); drainage and stormwater management features; and the flood zone designation and Base Flood Elevation (BFE) if the property is in a FEMA Special Flood Hazard Area.
For simple projects (like a shed or minor addition), a hand-drawn site plan based on a survey may be acceptable. For larger projects, a survey-based site plan prepared by a licensed surveyor is typically required. In some jurisdictions, a boundary survey must accompany the permit application.
Coastal and flood zone projects have additional site plan requirements, including the location of the Coastal Construction Control Line (CCCL), setback from mean high water, and any required coastal armoring or erosion control measures.
Architectural Drawings
For most residential projects above a certain threshold and all commercial projects, architectural drawings sealed by a licensed Florida architect are required. Architectural drawings typically include floor plans showing room layout, dimensions, door and window locations, and square footage; exterior elevations showing all four sides of the building; building sections showing interior heights and construction assembly; roof plan; reflected ceiling plans (for commercial projects); door and window schedules; finish schedules; and energy code compliance documentation (Florida Energy Code).
For simple residential projects — like a small addition or a garage — some building departments will accept drawings prepared by a licensed engineer rather than an architect, or may accept owner-prepared drawings for very minor work. However, for new residential construction and most commercial work, a licensed architect is required.
Architectural drawings must comply with the Florida Building Code and any local amendments. They must show compliance with accessibility requirements (ADA and Florida Accessibility Code) for commercial projects and must coordinate with the structural and MEP drawings.
Structural Drawings and Calculations
Structural drawings sealed by a licensed Florida professional engineer (PE) are required for any project involving structural systems — new construction, additions, structural modifications, and projects in flood zones. Structural drawings typically include a foundation plan showing the type, size, and location of all foundation elements; a framing plan showing all structural members (beams, columns, joists, rafters); connection details showing how structural members are connected; and structural notes specifying materials, grades, and construction requirements.
For projects in Florida's high-wind zones, structural drawings must include wind load calculations demonstrating compliance with ASCE 7 and the Florida Building Code. The design wind speed varies by location — from 130 mph in inland areas to over 185 mph in the Florida Keys. Structural drawings must also address uplift loads on the roof, which are critical in Florida's hurricane-prone environment.
For projects in FEMA Special Flood Hazard Areas, structural drawings must demonstrate compliance with flood-resistant construction requirements, including the elevation of the lowest floor above the Base Flood Elevation, flood-resistant materials, and flood opening requirements for enclosed areas below the BFE.

MEP Drawings (Mechanical, Electrical, Plumbing)
Mechanical, electrical, and plumbing (MEP) drawings are required for projects involving these systems. The level of detail required varies by project scope and jurisdiction.
Mechanical drawings show the HVAC system layout, equipment specifications, ductwork routing, and ventilation calculations. For commercial projects, mechanical drawings must demonstrate compliance with the Florida Mechanical Code and energy code requirements. Residential HVAC permits often require a Manual J load calculation to verify that the equipment is properly sized for the building.
Electrical drawings show the electrical panel schedule, circuit layout, outlet and fixture locations, and load calculations. Commercial electrical drawings must comply with the National Electrical Code (NEC) as adopted by Florida. For large commercial projects, electrical drawings must be prepared by a licensed electrical engineer.
Plumbing drawings show the water supply and drain-waste-vent (DWV) systems, fixture locations, and isometric diagrams. For commercial projects, plumbing drawings must comply with the Florida Plumbing Code and may require calculations for pipe sizing and fixture unit counts.
For simple residential projects, MEP drawings may not be required — the contractor's license and permit application may be sufficient. For commercial projects and complex residential work, full MEP drawings are typically required.
Additional Documents and Special Requirements
In addition to the drawings described above, Florida permit applications may require additional documents depending on the project type and location. Common additional requirements include: product approvals for windows, doors, and roofing materials (especially in the HVHZ); a Notice of Commencement (NOC) for projects over a certain value; contractor license and insurance certificates; owner authorization (if the contractor is applying on behalf of the owner); HOA approval letters (some jurisdictions require proof of HOA approval before issuing a permit); and environmental permits for projects near wetlands, waterways, or protected species habitat.
For projects in the Coastal Construction Control Line (CCCL) zone, a separate CCCL permit from the Florida Department of Environmental Protection (FDEP) may be required in addition to the local building permit. CCCL permits have their own drawing requirements and review process.
For commercial projects, additional documents may include a fire protection plan (for buildings with sprinkler systems), a food service plan (for restaurants), an accessibility compliance statement, and a stormwater management plan.
Frequently Asked Questions
Do I need an architect for a residential addition in Florida?
For most residential additions in Florida, a licensed architect is required to prepare and seal the architectural drawings. However, for simple additions under a certain threshold, some building departments may accept drawings prepared by a licensed engineer. Check with your local building department for the specific requirements in your jurisdiction.
What is a permit set?
A permit set is the complete package of construction documents submitted to the building department for permit review. It typically includes the site plan, architectural drawings, structural drawings, and MEP drawings, along with any required calculations and supporting documents. A complete, well-prepared permit set is the key to a smooth and fast permit approval.
Do I need structural drawings for a simple room addition in Florida?
Yes, in most cases. Any addition that involves new structural elements — a new foundation, new framing, a new roof — requires structural drawings sealed by a licensed Florida PE. The structural drawings must demonstrate compliance with the Florida Building Code's wind load requirements for your location.
What is a Manual J calculation and when is it required?
A Manual J calculation is a heat load and cooling load calculation that determines the proper size of HVAC equipment for a building. In Florida, Manual J calculations are required for new construction and HVAC replacements in many jurisdictions. The calculation ensures that the HVAC system is properly sized — an oversized system wastes energy and creates humidity problems, while an undersized system cannot maintain comfort.
