OFM Notes Providing Additional Design/Installation Details

Note 1: (see NFPA 13 for additional information)

  • Bathrooms do not require sprinklers if area ≤ 55 sq. ft. and walls are noncombustible or limited combustible providing a 15-minute thermal barrier rating. Exception does not apply in care occupancies and care and treatment occupancies, and in bathrooms that open directly onto public corridors.
  • Closets/pantries do not require sprinklers if area ≤ 24 sq. ft., least dimension ≤ 3 ft. and walls/ceilings are surfaced with noncombustible or limited combustible materials.
  • Sprinklers needed below exterior balconies if of combustible construction and the width exceeds 4 ft.

Note 2: (see NFPA 13R for additional information)

  • Bathrooms do not require sprinklers if area ≤ 55 sq. ft.
  • Closets/pantries do not require sprinklers if area ≤ 24 sq. ft., least dimension ≤ 3 ft. and walls/ceilings are surfaced with noncombustible or limited combustible materials.
  • Design criteria for areas outside dwelling units shall comply with NFPA 13, except that system demand is permitted to be limited by compartment area. System demand does not have to be greater than the demand for 4 heads where the area is compartmented into areas of 500 sq. ft. or less by 30-minute fire-rated construction.
  • Attached garages are not exempt from requiring sprinklers.
  • Attached open porches, open balconies, and exterior corridors/stairs do not require sprinklers.

Note 3: (see NFPA 13D for additional information)

  • Bathrooms do not require sprinklers if area ≤ 55 sq. ft.
  • Closets/pantries do not require sprinklers if area ≤ 24 sq. ft., least dimension ≤ 3 ft. and walls/ceilings are surfaced with noncombustible or limited combustible materials.
  • Attached garages or carports, open porches, open balconies, and exterior corridors/stairs do not require sprinklers.

Note 4: Section 9.7 of the Ontario Fire Code requires 20 minute water supply duration
