Second Dwelling Unit Ottawa designs, permits, and builds Additional Dwelling Units across the entire city, not just in a handful of neighbourhoods. The 15 areas below are where we field the most questions, each with its own mix of lot sizes, housing age, and zoning quirks that shape what fits on a given property – but the underlying process, and our coverage, is citywide.
Why area matters, even though zoning is really about the lot
Two houses on the same street can qualify for different Additional Dwelling Unit types once you factor in lot coverage already used, setback distances, and whether the property is on municipal or private services. What an area page gives you is context – the kind of lot sizes, housing stock, and local rules that are common in that part of the city – not a substitute for a feasibility review of your specific address, which is still the first real step in every project.
Coverage questions
My neighbourhood isn't listed by name – do you still cover it?
Very likely, yes. These 15 pages cover the areas we get asked about most, but zoning applies property by property across the entire city, not just in named neighbourhoods. Contact us with your address and we will confirm.
Does the ADU type available to me depend on which area I'm in?
Not directly – what matters is your specific lot's zoning, size, and servicing, which varies within every area on this list, not by neighbourhood name alone. The area pages describe general patterns (lot size, housing age, servicing) that are common locally, not a fixed rule for every property there.
