This is brilliant. When will someone present this to city council as a solution to Edmonton's own sprawl problem?
And so what if single-family developers take their business to bedroom communities, or to other cities entirely? We need to look out for our #1, our Edmonton. We need to fill our surface lots, brownfields, and TOD proposals, all sooner rather than later.
We actually did something similar last year (in fact, beating Minneapolis to it); RF1 zoning, previously limited to SFH, now allows duplexes, and each of those units is allowed a secondary suite on top of that.
Edmonton made a historic move on housing the other day when it allowed duplexes to be built anywhere in the last remaining neighbourhoods.
