Duplex infills
With the age of some of the more mature communities approaching 70-80+ years, many houses may be reaching the end of their life span. This is leading to a large increase in the amount of teardown/rebuilds currently under construction. If you’ve thought about doing a teardown and replacing it with a duplex, here is some information you will need to consider:
1) Zoning – there is potential to do a duplex for lots zoned RF4 (the most common designation). RF1, RF2 and Rf3 zoning are also usually acceptable for duplex development.
2) Lot size- needs to be minimum 14.4 m wide, 30 m deep and over 442.2 sq m for duplex.
3) Total site coverage- maximum 40-45% (includes garage) depending on lot and area
4) Application – Here is a link to the form you would need to submit to get approval from the city:

5) Building costs – There is a large range in costs depending on the builder you use, and the quality of product you build. However, I have received estimates in the range of $200-$225/sq foot. The reason it is a bit higher is because of the need for twice as many of the expensive areas (ie. mechanical, electrical, kitchens,etc…)
