How high are you allowed to build a scaffold that is 5 feet wide by 7 feet long before you have to tie guy or brace the scaffold?

In general, scaffolds that are 5 feet wide and 7 feet long must be braced or tied when they exceed a height of 4 times their minimum base dimension. For this scaffold, that means it can be built up to 20 feet high before requiring bracing or guying. However, local regulations and safety standards may vary, so it's essential to consult specific guidelines and regulations applicable to your location.
