How Many People Can Share a Bedroom?

When it comes to determining how many people can share a bedroom, the Canada Mortgage and Housing Corporation (CMHC) provides clear guidelines through its National Occupancy Standard (NOS). These standards are essential for assessing housing suitability, particularly in the context of affordable housing programs. Understanding and applying these guidelines can help ensure safe, comfortable, and legally compliant living arrangements.

The Two-Person Per Bedroom Rule

According to CMHC, suitable housing is defined as having enough bedrooms for the size and composition of the household. The NOS stipulates that a maximum of two persons per bedroom is considered appropriate. However, there are specific exceptions to this rule:

  • Lone Parents: Have a separate bedroom from their children.

  • Adults Aged 18+: Have a separate bedroom, except those living as part of a married or common-law couple.

  • Same-Sex Children Under 18: May share a bedroom.

  • Opposite-Sex Children Under 5: May share a bedroom if it reduces the total number of bedrooms needed.

These guidelines help in determining the number of bedrooms needed to accommodate a household without overcrowding, which is a key factor in assessing housing suitability.

Why It Matters for Landlords and Renters

Understanding how many people can share a bedroom is crucial for both landlords and renters. For landlords, following CMHC standards helps ensure compliance with occupancy regulations, reduces wear and tear on the property, and improves tenant satisfaction. For renters, these guidelines support health and safety by preventing overcrowding, protect legal rights, and ensure privacy and comfort for all household members.
