• Provide the owner an opportunity to
evaluate the design in terms of
livability and suitability
• Quickly communicate overall

builder
• Reduce likelihood of errors if they are
easy to read

 Stairs
• Width between 36” and 42”
• Tread/ Run =width
- 10” Minimum
• Riser = height
- 7.75” Maximum
• Spiral stairs must have adequate headroom and all risers must be
equal height and smallest portion may not be smaller than 6”
Stairs on the Floor Plan






DN = Down, UP = Up, R = Risers
Rise is one riser and Run is one tread
Always one less run than rise
Stair length = tread length X number or runs
Landings are at least 36” x 36”
Stairwell opening can cover up to 1 ½ steps without having to angle
Calculating the stairwell opening required:
6’-8” = 80”
Max rise = 7.75”
80/7.75= 10.3 or 11 risers
11 x 10 runs = 110” or 9’-2”
Typical Stair Detail
Hallways on Floor Plans
 Hallways provide access to various areas
• May be long or short
• Length and number should be minimal
• May be a unique part of the design
• Minimum finished width should be 36"

CAD Symbols made easy!
 Floor-plan symbols can be
placed using the AutoCAD
Design Center or Tool
Palettes
 Use correct layers when
inserting symbols
