Building Section Drawing Requirements

A building section shows a view along an imaginary line cut through the building, indicating structural and construction elements.

Use the following checklist to ensure your drawings are complete and provide enough information to verify Building Code requirements. A sample drawing is shown below.

Your building sections must show, as a minimum (other features not listed here should also be identified):

  • Project location
  • Designer’s name and Building Code Identification Number (BCIN), if applicable
  • Scale of drawings
  • Building components (roof, walls, floors, foundation, etc.)
  • Height of building
  • Size of building
  • Materials used in the building
  • Roof slope or pitch
  • Room names
  • Top of top plate elevation
  • Top of floor sheathing elevation
  • Top of finish grade elevation
  • Bottom of footing elevation
  • For additions, relationship to existing building
