What standard governs the maximum distance from dwelling units to exits?

The maximum distance from dwelling units to exits is primarily governed by BP 220, which stands for "Batas Pambansa Blg. 220." This law specifically addresses the requirements for economic and socialized housing in the Philippines and includes provisions for safety measures, such as egress requirements to ensure that residents can quickly and safely exit their homes in case of an emergency. It lays down precise standards for the design and layout of residential buildings, which include specifications on exits and their locations relative to dwelling units.

While other building codes and regulations, such as the International Building Code and the National Building Code, also cover egress and emergency exits, BP 220 is particularly focused on the context of housing development in the Philippines. Local zoning regulations may address land use and density but do not typically provide detailed requirements specifically related to exits from dwelling units. Therefore, BP 220 is the correct standard governing the maximum distance from dwelling units to exits in the context of this question.
