How can we add a driveway to a property? (NJ)

[Carlos Albarracin]

Hey! Currently working on a duplex property in North Jersey and see that it currently does not have a driveway. However, the backyard from what we can see has space to do the paving/blacktop on it to fit 2-4 cars. Currently there is no fence to close off the backyard, just grass and seems like previous owner was parking cars on top. Does anyone know what permits or licenses are required for a project like this? Or any other advice regarding the process? Appreciate the help in advance
