Basement ADUs – Affordable Additional Living Space in Sarnia, Windsor, Chatham, and London

​

Unlock the Benefits of the Secondary Suite Loan Program!

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

Why Choose a Basement ADU?

• Lower Construction Costs – Since the structure already exists, a basement conversion is far 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 – 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.

• Private & Self-Sufficient Living Space – A well-designed basement ADU includes a separate entrance, kitchen, bathroom, and living area for complete privacy and comfort.
