Lauren - Electrical code requirements are generally enforced by the authority having jurisdiction (AHJ) for the region. This individual determines what requirements apply (in accordance with local legislation), and what exceptions may be possible or acceptable. The general rule is adherence to the code, because you plan for general deployment. The risk of not following code can mean prevention of equipment connection by the AHJ until compliance is achieved.
