This proposal only applies to parapet walls at the perimeter that are less than 30 inches.
Ibc roof parapet height.
The ice barrier should extend from the lowest edges of all roof surfaces and extend at least 24 inches inward from the exterior wall line of the building.
The height of the parapet shall not be less than 30 inches.
Where the vasd as determined in accordance with section 1609 3 1 is 110 mph 177 km h or greater or the mean roof height exceeds 33 feet 10 058 mm drip edges shall be mechanically fastened a maximum of 4 inches 102 mm on center.
Many manufacturers limit the use of the ice barrier to 24 inches maximum from the exterior wall line or require special ventilation if the ice barrier extends inward for more than 24 inches.
Drip edge shall be mechanically fastened a maximum of 12 inches 305 mm on center.
This language will allow a greater variety of options for waterproofing the parapet wall.
If a reinforced concrete beam is provided at the top of the wall the minimum height above the wall anchor may be 6 inches 152 mm.
However when a roof slopes down toward an exterior wall and parapet with a slope greater than 2 12 further analysis is required to determine if a taller parapet is necessary.
Osha guardrail height requirements osha also requires a top rail at 42 above the working working surface but allows for some flexibility of 3 inches from the 42.

Ibc guardrail height requirements ibc guardrail is required to be a minimum of 42 above the leading edge of the tread or walking surface.
The international code council icc is a non profit organization dedicated to developing model codes and standards used in the design build and compliance process.
Section 705 11 1 of the ibc for parapet construction requires that parapet walls be not less than 30 inches.
Unfortunately many buildings get close to this height without quite meeting the height required by osha to provide fall protection.
The minimum height of a parapet above any wall anchor shall be 12 inches 305 mm.
Parapet corrective work must be performed in conjunction with the installation of tension roof anchors.
The international codes i codes are the widely accepted comprehensive set of model codes used in the us and abroad to help ensure the engineering of safe sustainable affordable and resilient structures.
