Can Your Basement Legally Become a Suite in Ottawa?
Thinking your basement could help carry the mortgage? The first question isn’t flooring or paint, it’s whether your lot, ceiling height, and entrance can support a legal secondary dwelling unit, and what it would realistically rent for. We answer both before you commit to a build, so you know from day one that it’s legal, insurable, and worth it.
Four things decide feasibility: ceiling height (and whether underpinning is needed to gain it), a compliant entrance, fire separation between the suite and the rest of the house, and an egress window sized for a sleeping room. A feasibility assessment checks each one against your actual home, not a generic checklist, and tells you plainly whether the suite is straightforward, needs structural work first, or isn’t the right move for your lot.
Legal Suite & SDU Options
Most Ottawa basements become a compact, code-correct one-bedroom or bachelor unit. The right layout depends on your stairs, your windows, and where the plumbing already runs, we design around what your house gives us, not around a template.

How Our Legal Suite Process Works
It runs in plain stages, so you’re never guessing what’s next.
-
Feasibility assessment
We confirm the suite is legal on your lot, ceiling height, entrance, fire separation, and egress, and give you a labelled cost range before you commit.
-
Permit drawings
We prepare and submit the City of Ottawa permit package: fire separation, egress, ventilation, and the lot.
-
The build
Framing, fire-rated separation, egress, kitchen, and bath, inspected at each required stage.
-
Inspection & handover
You finish with a unit that passes inspection, that your insurer will cover, and that you can rent with confidence. Every required permit is pulled, we don’t do off-the-books work.
What a Legal Suite Costs in Ottawa, and What It Rents For
A legal suite costs more than a plain finish because it adds a kitchen, a full bathroom, fire separation, egress, and permits, typically a kitchenette around C$5,000–C$30,000 and a bathroom around C$8,000–C$15,000 on top of the finished space. We give you the full number line by line before any work starts, so there’s no “call for quote” and no surprises.
Here’s the math that earns the cautious yes: a compliant one-bedroom basement suite in much of Ottawa rents in the four figures a month, which can offset a meaningful slice of a typical mortgage payment. We build you a real rent-versus-cost picture tied to your neighbourhood, Orléans, Gloucester, Nepean, Barrhaven, so the decision is made on numbers, not optimism. Done right, you get to say: “I built a legal apartment downstairs, and it pays for a third of my mortgage.”
