Scaffold Permit Question

We are looking to replace a section of our façade that currently has siding installed with new stucco. It amounts to maybe 1/3 of the total façade, the rest of which will stay intact. We found a reputable contractor who has done all the stucco work in our neighborhood and he is ready to go but he wants us to handle the permits if we need them.

I’ve been researching this and it seems that we are okay with up to 1 inch of stucco according to this link http://home2.nyc.gov/html/dob/html/reference/tppn0199.shtml. However it is unclear to me if we need a permit for the scaffolding. The contractor would not use hanging scaffolding; he will have the base for all the scaffolding within our property line and will use netting. However I can’t seem to find a clear answer as to whether or not the cut off for when you need a permit is if the scaffold is over 40 feet high or the building is over 40 feet high. Our building is 42 feet high but the contract is saying he would not need to build the scaffold that tall since the section to be stucco’ed is not up that high. Does anyone know where this is spelled out on the DoB website? If we do need a permit where do I apply for that? I only see info for hanging scaffolding on the DoB site. Thanks in advance for your help.
