3.1 If an area containing a primary function has been altered without providing an accessible path of travel to that area, and subsequent alterations of that area, or a different area on the same path of travel, are undertaken within three years of the original alteration , the total cost of alterations to the primary function areas on that path of travel during the preceding three year period is to be considered in determining whether the cost of making that path of travel accessible is disproportionate.

Listed conventional battery-operated smoke alarms or listed battery operated low-power radio (wireless) alarms are permitted to be installed in these existing finished areas.
307.1.2Interconnection. Where more than one smoke alarm is required to be installed within an individual dwelling unit in accordance with Section 307.1, the alarm devices are to be interconnected in such a manner that the actuation of one alarm will activate all of the alarms in the individual dwelling unit.
