What Is a Secondary Dwelling Unit (SDU)?

Modern Living Space - Haven Renovations

An SDU is a self-contained apartment within a single-detached, semi-detached, or townhouse dwelling. It includes its own kitchen, bathroom, sleeping area, and private entrance.

In Ottawa, many homeowners know SDUs by another name: basement apartments. Haven Renovations Inc. specializes in turning underutilized basements into fully legal, income-generating secondary dwelling units.

Benefits of an SDU

  • Earn passive rental income
  • Increase property value
  • Help solve housing shortages
  • Accommodate multi-generational families
