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"
