Canadian building code question

What are the building code requirements for self-storage facilities in Canada?

Self-storage facilities are typically classified as storage occupancies under the NBC, with requirements for fire separation between units, sprinklering based on building size, construction type limits based on building area and height, and specific access and egress provisions.

Self-storage facilities present unique code challenges because they combine large undivided floor areas with storage of unknown materials by tenants. The building code classifies these as storage occupancies and applies requirements for construction type, fire separation, sprinklering, and means of egress based on building size and occupancy characteristics.

What to check first

  • Self-storage is typically classified as a Group F, Division 3 (low-hazard industrial) occupancy, but contents can change the classification.
  • Sprinklering requirements depend on building area, height, and construction type.
  • Fire separation between individual storage units may be required depending on unit size and building configuration.

Jurisdiction notes

National baseline

The NBC classifies self-storage under industrial occupancy provisions with fire separation and construction requirements based on building size.

Provincial adoption

Some provinces have specific guidance for self-storage facilities that supplements the NBC baseline occupancy classification.

Project variables

Building size, number of storeys, climate-controlled vs. non-climate-controlled units, and tenant access patterns all affect requirements.

Work through it in this order

  1. Confirm the occupancy classification for the self-storage facility under the applicable code.
  2. Determine construction type limits based on building area and height.
  3. Check sprinklering and fire separation requirements.
  4. Verify means of egress, access, and fire department access provisions.

Common questions

What occupancy classification applies to self-storage?

Self-storage is typically classified as Group F, Division 3 (low-hazard industrial) under the NBC, but this can change if hazardous materials storage is permitted.

Are sprinklers required in a self-storage building?

Sprinkler requirements depend on building area, height, and construction type — many self-storage buildings exceed the thresholds that trigger mandatory sprinklering.

Do individual storage units need fire separations?

The requirement depends on building configuration and whether the units are treated as separate suites or open storage areas under the code.
