Does an ADU need to meet building and fire codes?

Because an ADU is a distinct dwelling unit, it must have its own utilities and shut-off access, except as the Building Code or Building Official may allow. The creation of an “accessory suite” (an attached ADU) must also have fire and sound separations as required by Building Code and/or Building Official.
