That depends upon what you (and your neighbors) call a "campfire."  A small open-air fire in a pit (no more than 3' wide), distant from a tree line or overhead combustibles (like tree branches) for the purpose of cooking hot dogs and marshmallows is probably all right.  However, upon the complaint of a neighbor or even a passerby, we are required to investigate and possibly order the fire extinguished.  Your best long-term option is to build on outdoor barbeque or let your neighbors know your intentions.
