Aging-in-place design is about preserving independence while creating a living environment that prioritizes accessibility, safety and comfort. However, for some seniors, modifying their existing home may not always be the most practical solution due to a need to be close to family members for healthcare assistance. Structural limitations, cost, or space constraints can also play a part in the decision process. This is where Accessory Dwelling Units (ADUs) offer an innovative and adaptable alternative.

ADUs, also known as in-law suites, garden suites, or secondary dwellings, provide a self-contained, accessible living space that allows older adults to remain close to family and essential support networks while maintaining autonomy. Whether built as a standalone unit in a backyard, a converted basement suite, or an extension of the main home, ADUs are designed to accommodate aging-related needs with features such as step-free entryways, wider doorways, accessible bathrooms, and open-concept layouts that enhance mobility.
Beyond convenience, ADUs nurture intergenerational living, strengthening family connections while offering a safe and manageable space that has the potential to evolve with changing health needs. They provide a cost-effective solution for families looking to support aging relatives while avoiding the financial and emotional challenges of long-term care facilities.
Accessory Dwelling Units (ADUs) as a Practical Aging-in-Place Solution
Aging-in-place housing is about adapting living spaces to support mobility, safety, and accessibility as needs evolve. For some seniors, modifying their existing home may not be the best or most feasible solution. Accessory Dwelling Units (ADUs) offer a flexible alternative, providing a private, self-contained living space designed with aging-in-place principles in mind.
ADUs support aging in place by incorporating:
Barrier-free access – Step-free entryways, wider doorways, and open floor plans allow for easier movement especially if using a mobility aid.
Safety enhancements – Non-slip flooring, brighter lighting and grab bars all help prevent falls, the leading cause of injury for older adults.
User-friendly design – Lever-style handles on doors, walk-in showers with zero clearance entry and accessible kitchen storage reduce strain and improve functionality.
Beyond accessibility, ADUs allow seniors to stay close to family and support networks, reducing social isolation and providing peace of mind. Whether attached to an existing home or built as a separate unit, an ADU creates a comfortable, manageable space that prioritizes independence while offering the reassurance of nearby assistance if needed.
Key Design Considerations for ADUs for Seniors
To maximize comfort and functionality, an ADU designed for Aging- in-Place should include:
Open-Concept Layouts: These enhance mobility and make navigation easier for those using mobility aids.
Step-Free Entry and Wider Doorways: Essential for a walker or wheelchair access and minimizing tripping hazards.
Non-Slip Flooring: A crucial safety feature in all areas, especially the bathroom and kitchen.
Deep rollout drawers and Pull-Out Pantries: These provide easy access to everyday essentials without excessive bending or reaching.
Walk-In Showers with Grab Bars: Offering safety and ease of use for all levels of mobility.
Good Lighting: Adequate illumination enhances visibility and reduces fall risks.
Flexible Multi-Use Spaces: A well-designed ADU can serve as a comfortable living area, a guest suite, a home office, or a caregiver space as needs change.
Financial Assistance: The Multigenerational Home Renovation Tax Credit (MHRTC)
The Government of Canada recognizes the need for flexible housing solutions for seniors and offers financial support through the Multigenerational Home Renovation Tax Credit (MHRTC).

Homeowners can claim up to $50,000 in qualifying renovation expenses to create a self-contained unit for a senior or an adult eligible for the disability tax credit.
The tax credit covers 15% of the renovation costs, providing up to $7,500 in financial relief per eligible project.
This initiative makes ADUs a more financially viable option for families looking to invest in long-term, accessible housing solutions.
The Benefits of Sourcing Canadian
Sourcing materials locally can offer long-term benefits when building an Accessory Dwelling Unit (ADU). While online retailers may provide convenience, Canadian-made products often deliver higher quality, faster turnaround times, and fewer supply chain disruptions.
Avoid Tariffs & Delays – With ongoing trade discussions, Canadian-made materials help avoid unexpected import costs and shipping delays.
Superior Craftsmanship – Many local manufacturers specialize in high-quality cabinetry. Canadian fixtures are readily available & designed to last.
Sustainable & Ethical – Choosing Canadian-made products supports environmentally responsible sourcing and reduces the carbon footprint of long-distance shipping.
Since 2018, we have prioritized working with Canadian suppliers when possible, ensuring your renovation enhances your home and supports the local economy. Whether it’s custom cabinetry, kitchen finishes, or bathroom fixtures, sourcing Canadian-made materials means investing in durability, quality, and sustainability.
