The Rise of Secondary Dwellings: Unlocking Housing Potential in Kawartha Lakes and Peterborough County
After attending a recent economic development event and speaking directly with the mayor of the City of Kawartha Lakes, one thing became crystal clear: our region’s housing landscape is evolving, and homeowners have an unprecedented opportunity to be part of the solution.
The demand for more housing options is rising, and secondary dwellings—also known as Additional Residential Units (ARUs) or Accessory Dwelling Units (ADUs)—are a key piece of the puzzle. Whether you’re looking to generate rental income, create multi-generational living spaces, or boost your property’s value, recent policy changes have made it easier than ever to add a secondary unit to your home.
But why is this shift happening now, and how can you take advantage of it? Let’s dive into the opportunities, the latest regulations, and why now is the perfect time to invest in an ADU.
What Are Secondary Dwellings?
A secondary dwelling is a self-contained residential unit located within, or in addition to, a primary residence. These units provide independent living spaces with their own kitchen, bathroom, and sleeping areas. Depending on your property and needs, secondary dwellings can take several forms, including:
- Basement apartments – Converting an underutilized basement into a legal rental unit.
- Garden suites or granny flats – A separate structure on the same lot as the main home.
- Coach houses – Living spaces above a garage or in a detached building.
- Garage conversions – Turning an existing garage into a livable unit.
- Standalone tiny homes – Small, fully functional homes built on the same property as the main house.
In the past, adding a secondary dwelling was a complicated process with restrictive zoning laws and red tape. However, with recent policy changes in Ontario, homeowners now have more flexibility than ever before.
Why Now? The Policy Shift in Ontario
Housing affordability and supply challenges have pushed Ontario to rethink its residential zoning laws. The passage of Bill 23: More Homes Built Faster Act, 2022 introduced major reforms designed to accelerate housing development. In areas like Kawartha Lakes, Trent Lakes, and Peterborough County, these changes mean:
✔ Homeowners can add up to two additional residential units per lot—one inside the main house and another in an accessory structure.
✔ Minimum unit size restrictions have been removed, making it easier to build smaller, more affordable spaces.
✔ Relaxed parking requirements, with only one parking space required per unit in many cases.
These changes open new doors for property owners, making it easier than ever to add rental units, create housing for extended family, or increase the value of their property.
Local Opportunities in Kawartha Lakes and Peterborough County
While the province has set the foundation for increased housing flexibility, each municipality has its own guidelines for implementation. Here’s what you need to know about secondary dwelling regulations in your area:
Kawartha Lakes
- Allows up to two additional residential units per lot—one in the main house and one in a detached structure.
- Units must be self-contained with a separate entrance, kitchen, bathroom, and living space.
- Local zoning and building codes still apply, and homeowners must register their additional units with the city.

Peterborough County
- Permits secondary units in urban and rural residential zones.
- Units must comply with the Ontario Building Code, Ontario Fire Code, and municipal regulations.
- The county emphasizes sustainable development, meaning septic capacity and well water supply may need to be assessed for rural properties.

Why Consider Building an ADU?
Adding a secondary dwelling isn’t just about increasing housing availability—it’s also a smart financial and lifestyle decision. Here’s why:
✔ Rental Income – A legal secondary unit can provide a steady stream of passive income, helping offset mortgage costs or other expenses.
✔ Multigenerational Living – Keep aging parents or adult children close while maintaining privacy and independence.
✔ Increased Property Value – Additional units can significantly boost resale value, making your property more attractive to future buyers.
✔ Flexible Use – Use the space for a home office, guest house, or future rental unit.
Homeowners who invest in ADUs today are future-proofing their properties while also contributing to the solution for Ontario’s housing crisis.
