Learn about the Secondary Suite Loan Program!

A basement ADU is one of the most cost-effective ways to add a fully functional additional dwelling unit (ADU) to your property. By converting an underutilized basement into a separate living space, homeowners in Chatham, Sarnia, Windsor, London, Leamington, and Belle River can unlock new income potential and maximize their home’s value.

Benefits of Basement ADUs

• Lower Construction Costs – Since the structure already exists, a basement conversion is more affordable than building a new addition or detached unit.

• Rental Income Potential – A self-contained basement apartment provides a steady stream of passive income, helping homeowners offset their mortgage or expenses.

• Multigenerational Living – A basement ADU is perfect for elderly parents, adult children, or extended family, offering independence while keeping them close.

• Increased Property Value – Homes with legal secondary units are more attractive to buyers and can command higher resale prices.

• Separate & Private Living Space – A well-designed basement ADU has a private entrance, kitchen, bathroom, and living area, making it a comfortable and self-sufficient unit.
