Question

in a building with both commercial and residential areas, which standard applies to door widths of habitable rooms to ensure compliance?
bp 344 mandates a minimum clear width of 0.90 meters for all doors regardless of function.
nbcp requires a minimum clear width of 0.90 meters for habitable spaces and main exits.
nbcp allows 0.80 - meter doors in residential occupancies with fewer than 10 units.
the fire code limits egress doors to a minimum of 0.85 meters across occupancy types.

Explanation:

Among the options, NBCP (National Building Code of the Philippines) regarding minimum clear - width for habitable spaces is a common and relevant standard for a building with both commercial and residential areas. The other options either have incorrect mandates (like BP 344's blanket statement), or are too specific to a certain condition (NBCP allowing 0.80 - meter doors in limited residential cases) or are about egress doors (Fire Code) rather than general habitable room doors.

Answer:

B. NBCP requires a minimum clear width of 0.90 meters for habitable spaces and main exits.
