In today’s housing landscape, the concept of “home” in Kingston is evolving quickly. As a local realtor, I’ve seen a clear shift toward multi-generational living and the growing demand for secondary suites—also known as Additional Residential Units (ARUs). What was once considered a niche feature is now becoming a mainstream solution to affordability, lifestyle changes, and long-term planning.
At the heart of this shift is affordability. With rising home prices and limited rental inventory, many buyers are seeking creative ways to offset costs. Secondary suites—self-contained units within or on the same property—are increasingly seen as a practical way to generate income and make homeownership more attainable. In fact, the City actively encourages ARUs as a way to increase rental supply, support homeowners financially, and diversify housing options.
But beyond economics, there’s a strong lifestyle component driving this trend. Multi-generational living—where parents, adult children, or extended family share a property—is on the rise across Ontario. In Kingston, this is especially relevant given the city’s aging population and strong ties to institutions like healthcare and the military. Many families are choosing to bring aging parents into the home, allowing them to “age in place” while maintaining independence through a private suite.
Modern secondary suites are designed with this balance in mind. Whether it’s a basement apartment, in-law suite, or detached garden suite, today’s units typically include separate entrances, kitchens, bathrooms, and living spaces. This allows for privacy while still keeping family close—a key factor for buyers navigating caregiving responsibilities or looking to support adult children entering the housing market.
Legislation has also played a major role in accelerating this trend. Ontario’s recent planning changes now allow up to three units on many residential properties “as-of-right,” removing much of the red tape that previously discouraged homeowners. Locally, Kingston has embraced this direction with zoning allowances, permit pathways, and even financial incentives to encourage the creation of new units.
Of course, there are still important considerations. Secondary suites must meet building code and fire safety requirements, including proper exits, fire separations, and adequate parking in many cases. Buyers should also be aware of the difference between legal and non-conforming suites, as this can significantly impact financing, resale value, and insurance.
From a real estate perspective, homes with legal secondary suites are some of the most sought-after properties in Kingston today. They appeal to a wide range of buyers—from investors looking for rental income to families planning for long-term flexibility. A well-designed suite can significantly enhance a property’s value and marketability, especially when it offers true self-containment and privacy.
Looking ahead, this trend shows no signs of slowing down. Innovative housing models, such as proposed multi-generational cohousing communities in Kingston, highlight a broader shift toward shared living and community-oriented design.
The “new reality” is clear: housing is no longer just about a single household under one roof. In Kingston, it’s about adaptability, sustainability, and making smart use of space. For buyers and homeowners alike, embracing multi-generational living and secondary suites isn’t just a trend—it’s a strategic move for the future.
As someone who has personally gone through the process of adding a secondary unit to a property, and who has experience as a landlord in Kingston, I understand both the opportunities and the challenges that come with designing a home for intergenerational living. This firsthand experience allows me to help clients not only find suitable properties, but also evaluate renovation potential, understand secondary suite considerations, and think through how a home can function well for multiple generations – whether that means accommodating family members or creating rental income to offset mortgage costs. I would be happy to help!
