It is her building and her liability. - 4x4s an only wood and really not that strong, depending on the height.
Your bike may be only 30#, but someone else may try to hang a 1500# moose from it.
The owner has the liability and has no guarantee what will be hung from the hook or if someone slse installs a bigger hook or decides to run a horizontal line where there could be very large horizontal loads.
I am sure you could get permission to do what you want if you provide a guarantee what loads would be applied and assume the liability.
