Generally speaking permits and the associated inspections are required in most municipalities if you are adding to or modifying the structure or any of the systems. Think about it this way....if you want to change out a light fixture using the current wires you do not need a permit. If you are adding a light fixture with new wiring, then you need a permit. Replacing a window? Same thing....replacing the window does not require a permit as long as you do not modify the size of the opening in the wall. Make sense?
As to adding a receptacle yes you are adding to or modifying the electrical system. There are many code issues associated with this type of work some of which have already been mentioned such as when/if GFCI protection is required. Another thing not mentioned is the load being added to the existing circuit and knowing what is already wired to the same circuit. A convenience outlet used every once in a while is one thing but an outlet to handle for example a pump for a water feature would be an entirely different situation. Pay for the permit, explain what you are doing and get some free advice from the inspection department before you start or better yet pay a professional to do the work and be safe!
