Every so often a contractor suggests that the homeowner pull the permit, usually framed as a way to save time or money. It is worth understanding what that actually means before agreeing to it. When your name is on the permit, you are the one the township holds responsible for the work meeting code. If an inspection fails, it is your problem to solve. If the contractor stops showing up, the open permit is attached to your address, not theirs.
There is also a quieter reason it gets suggested. A contractor who is not licensed or insured in the way the work requires may not be able to pull the permit themselves. That is worth knowing before the first check clears, not after.
A normal addition or remodel in this area means filing with the township, then a sequence of inspections as the job progresses: footing, framing, rough electrical, rough plumbing, insulation, and final. Someone has to schedule each of those, be on site when the inspector arrives, and fix whatever gets flagged before the next trade can cover it up. That coordination is a real part of the job and it belongs to the contractor.
It also protects the value of the work. Permitted, inspected work is documented, and that documentation shows up when you sell, when you refinance, and when you file an insurance claim. Unpermitted work that looks fine can still cost you at closing, when a buyer's attorney asks why there is a finished basement that the township has no record of.
