Building Permits - is there anyone who can provide advice?

[Kimberly Roth]

Hi, I have a trusted contractor that I am bringing in from out of state for a flip in Lakewood and we want to make sure we follow the right permit requirements. He has submitted his information to Lakewood for licensing but we haven't been able to get much info on permits.  Is there anyone who can shed some light on the process?  We are considering taking out a wall in the kitchen/living room but realize that will require a permit.  What do we need to do to get that approved? What is the turnaround time? Do we need architectural drawings? Who would I go to for this (first time flipper)?

Besides this, most of the changes are purely cosmetic to the house - removing wallpaper, replacing carpet, sanding hardwood floors, replacing bathroom tub and vanity. 

Thanks so much for your help!
