Bill,
NJ requires CO's before you can move in. Plus as someone said, the Zoning dept. will make sure about the grass, driveway, etc. We also have something we call CCO's which only applies to commercial buildings when one tenant moves out and another tenant moves in. The building Dept. will send out a 4 trades, to just double check the building. We look for safety issues and somethimes the building inspector will look for new work that was done since the last CCO.
