Basement Renovation Ottawa
Legalize a Basement Apartment Ottawa: Make Your Existing Unit Legal and Safe
Already have a basement apartment that isn’t legal? We retrofit Ottawa units to code, fire separation, egress, permits, and registration, without a full rebuild. Book an assessment.
Typical Ottawa cost
Scoped after a compliance assessment
Usually a targeted retrofit, not a rebuild, we cost only the items that don’t meet code (fire separation, egress, alarms, permits) after assessing your unit.
Permits
Pulled on every job
We pull every required City of Ottawa permit and manage the inspections, documented, insurable work.
Built to code
Confirmed before we build
We confirm your unit against the City of Ottawa’s current fire-separation, egress, alarm, and ceiling-height requirements, then permit and register the legalized suite.
Is Your Basement Apartment Actually Legal?
Plenty of Ottawa basements are rented out without being fully legal, often the unit came with the house, or was finished years ago before the rules tightened. There’s no judgment here. The good news is that legalizing it usually means a targeted retrofit, not tearing it all out and starting over.
The gaps we see most are the same four: missing or inadequate fire separation between the unit and the rest of the house, an egress window that’s too small (or absent), no interconnected smoke and CO alarms, and work that was never permitted. We start by finding exactly which apply to your unit, so you know the real scope.
What Legalization Involves
Legalization is a checklist, and we work through it: add the required fire-rated separation, enlarge or add an egress window, install interconnected alarms, confirm the ceiling height meets code, then pull the permits and register the unit. Each item is a defined, manageable piece, not a mystery, and most of them protect you directly the moment they’re done.

Retrofit vs Rebuild
In the large majority of cases this is a retrofit, not a rebuild, we upgrade the specific things that don’t meet code and leave the rest of your finished unit intact. That keeps cost and disruption down. Only rarely (usually a serious ceiling-height shortfall) does it make sense to go further, and we’ll tell you plainly if that’s your situation rather than letting you find out mid-project.
