Documentation, plans, proof that the plans comply with code, will require a licensed professional (architect or professional engineer.)

You need to find a GC who can recommend an architect and then work with the GC to get it built 

Also do you have an architect or expert I can talk with that can help me through this conversion?

Hi, I am a licensed architect in NYC/NJ.

My architect is working with a client that is attempting to utilize sb9 for a lot split and he is keeping me informed of the process.

One of my friend is looking for a recommendation for an architect in Raleigh.

I’m just trying to net work and further my education in the Realestate industry  In addition to the meetups I recommend you start interviewing agents, lenders, handymen, attorney's, architects, attorneys, insurance agents, property managers,... to build your team. 

I completed some due diligence - I spoke with an architect who gave me a quote for about $12K to close the permit.

Jalen - Some of the best ways to find contractors is to talk to architects, designers, engineers, realtors, property management companies other investors, Facebook groups, supply houses, home builders association and other contractors.Also check MLS for flip properties and new construction specs for sale.

It would be an awesome experience to go through the zoning process, architecting, building etc.Just some thoughts.
