A cross-section presents a view of the structure as if cut like a cake. It illustrates the relationship between various building components which are hidden in walls, floors and ceilings. Additional sections may be necessary at other locations to provide further detail. The location and perspective of each cross-section should be shown on the plans. A cross-section should include:

• Title of section
• Scale
• Size and type of footings and foundation walls
• Exterior and interior wall construction, including all components and finishes
• Roof, floor and ceiling construction, including all components and finishes
• Exterior ground levels
• Distance from grade to floor and to underside of footing
• Attic and crawl space ventilation
