Do we need to get a permit to rehab houses if my partner is a contractor?

Hi BP community, I have a quick question about permits and licensing. Me and my partner are looking for rundown properties in Jersey City to rehab and renovate. He is a contractor in NY but not licensed in NJ. I'm just wondering if we need to get a permit or license to do the job or can we just go in and do the work ourselves? Thank you.
