construction permits in NJ

[Rene Bee]

Hi Everyone, 

I'm getting some conflicting info and hoping I can get clarity here.  I am undertaking a gut rehab.  I'm waiting for revised architect drawings.  So will have to submit the drawings, construction permit, building permit, electrical and plumbing permit.  

a. Some are saying I have to prepare an application for all the permits at once.  Basically the contractor will gather all the permits and submit it all to the city of Newark.  That will be a complete packet for the project.

b. I had a advisor tell me today that I don't have to wait to submit all the permits all at once.  The plumber can submit his application and the electrician can submit their application so things can potentially move faster.  Then the contractor submits the plans and construction and building permits.

Which is correct?

Thanks!
