Small backyard homes could offer both housing and climate relief

Small backyard homes could offer both housing and climate relief

From CBC News:

Change is taking root in the Toronto housing scene.

In February, city council voted to allow homeowners to build a garden suite, or secondary residence, in their backyards. It’s part of a housing strategy that aims to address Toronto’s rental crunch.

Proponents say garden suites, along with laneway suites (which were approved in 2018), are a much-needed tool to gently add density to existing residential neighbourhoods — an alternative to highrises or car-dependent sprawl and part of the city’s broader sustainability goals.

Other cities in Ontario (BarrieKitchener) and across the country (like Vancouver, Calgary and Edmonton) already allow garden suites. Toronto looked closely at some of those plans to see what worked best to address zoning issues.

Karen Chappele, director of the University of Toronto’s School of Cities, has studied garden suites extensively and says 60,000 were built in California, mostly in Los Angeles, over the last three years alone. She says the concept “takes pressure off of the rest of the housing market.”

“Even if it’s not an affordable unit for a low-income family, [a garden suite is] accommodating somebody who’s not going to displace a low-income family in an affordable unit.”

Proponents of garden suites say the benefits are many. Homeowners can use the rent to help pay off their mortgage, or as a residence for their adult children, who might not be able to afford to buy in the same area. Some want a residence for elderly parents or a caregiver for themselves.

In terms of sustainability, the small size means less building material and the location allows it to tap into existing amenities in the main house, like electrical or plumbing infrastructure.

François Abbott, an architect and owner of Toronto’s Fabrication Studio, says that in general, garden suites promote a more climate-friendly lifestyle. “There’s less consumerism because you’re in a small space. You’ve got to just pick and choose your objects carefully,” he said.

Craig Race, architect and co-founder of Toronto firm Lanescape, agrees.

“They can be as sustainable as you want them to be. Passive house, off grid, you name it — those opportunities are there.”

Race says garden suites alone won’t fix everything, but adds that “Toronto has a huge ‘tall and sprawl’ problem — highrises and single-family homes and not much else.”
