I own a gutted house and I want to GC the rehab myself

[Anthony Theokary]

Hi all I have a few questions and hope you can help me along the way. I own a 2 story house in South Philly and it’s fully gutted. I am putting a 3rd floor on and already have my zoning permits and waiting on construction plans. I DO NOT have my GC license. I want to know what I can do as the homeowner as far as pulling permits for all the work? Do I need my license?  If anyone can help me with this question please let me know.
