Secondary dwelling units (SDUs), also known as accessory dwelling units (ADUs), have gained popularity among homeowners seeking to maximize space and property value. Whether you’re looking to expand living space or explore rental income opportunities, SDUs offer a versatile solution. Here’s everything you need to know about integrating an SDU into your property and how Ottawa Home Contractors can assist you every step of the way.
What is a Secondary Dwelling Unit?

A secondary dwelling unit is a self-contained living space located on the same property as a primary residence. SDUs can take various forms, such as detached backyard cottages, converted garages, basement apartments, or additions above garages. They typically include a kitchen, bathroom, living area, and bedroom(s), offering flexibility in usage.
Benefits of Secondary Dwelling Units
Increased Property Value:

Adding an SDU can significantly enhance your property’s market value. It provides additional living space or rental income potential, making your property more attractive to buyers.
Versatility:
SDUs can serve multiple purposes, such as housing for extended family members, rental income generation, a home office, or guest accommodation. They offer flexibility to adapt to changing family needs or lifestyle choices.
Cost-Effective Expansion:
Building an SDU is often more cost-effective than purchasing a separate property or renovating the primary residence. It maximizes underutilized space on your existing property while maintaining privacy and independence.
