Vancouver's new duplex rules explained

On Thursday, Vancouver city council voted 7 to 4 in favour of allowing avast rezoning of the city's low-density, single-family (RS) neighbourhoods to allow duplexes.

Here's what you need to know about the changes.

What's new?

Duplexes are now permitted on 99 per cent of Vancouver's single-family zoned properties.

What does it mean?

Essentially, it means it is now legal to buildas many as four housing units on an RS lot, instead of the maximum of three previously allowed.

How does that work?

Under the old system, a single-family zoned lot was allowed to contain a primary residence, a secondary suiteand a lanewayhouse. With the bylaw amendments, each duplex unit can have its own secondary suite.

Can you build a duplex with a laneway house?

No. This is the current rule, and it hasn't changed.

If you build a duplex, can you sell half of it?

Yes. According to Vancouver's chief planner, Gil Kelly, this is one of the key benefits of the new duplex option.

"One advantage here is that it allows two ownership homes on one parcel," he said. "It doesn't take away from the option to do alaneway instead, but it does allow one more "affordable" if you want to call it that option that isn't there now.

How will this impact the affordabilitycrisis in Vancouver?

It won't impact it much, and the cityacknowledges that. WithVancouver duplexes rangingin price from about $1 million to$2 million, Kelly says the duplexchange wasn't madeto address the "hardcore affordability problem."

"This was really meant to address options for owners, although with the ability to do [secondary] suites which typically are rented out, we could see a bump in the rental supply as well."

How will this impact housing stock in Vancouver?

Not by a significant amount.

According to a planning report by city staff,about 800 houses are demolished and replaced with a new house or house with secondary suite annually. The report states,"if patterns continue and half of the homeowners who are planning to replace a house in the coming year chose to rebuild using the new duplex option, we could see about 400 duplexes built over the course of a year."

How many properties are we talking about?

The city says the new duplex zoning affects 99 per cent of all the single-family lots in the city or about 67,300 of a total of 68,000 lots.

Why are some properties exempt from the change?

According to the city report, the area roughly between West 37th and West 49thavenuesand Granville and Cypress streets is "generally comprised of large, irregular lots with a significant stock of character homes..."

The report says the area requiresmore extensive and complex bylaw amendments which require more time and would have delayed bringing in duplexes on theother 99 per cent of the single-family properties in the city.

Those amendments are expected to be introduced at a later date.
