Buildings taller than 15 feet are required to have an inside means of access to the roof for several important reasons primarily concerning safety and accessibility.

From a safety standpoint, providing proper access to the roof enables firefighters and other emergency personnel to quickly reach the roof in case of fire or other emergencies. This access is crucial because many modern buildings incorporate rooftop equipment such as HVAC systems that require maintenance or emergency shutdowns. Furthermore, adhering to these regulations helps ensure that maintenance personnel can safely conduct routine inspections and repairs, minimizing risks associated with working at heights.

The specification of 15 feet as the relevant height standard comes from various building and fire codes, which recognize this height as a threshold where the risks of access and emergency situations increase. Ensuring that structures above this height are equipped with safe, reliable means of access helps streamline safety protocols and maintain compliance with industry regulations.
