REQUEST A QUOTEA Basement Suite Built to Code
A legal secondary suite is a construction project with real requirements — ceiling heights, egress, fire separation, sound control and moisture management. We handle the full build: framing, insulation, drywall, bathrooms, kitchenettes and finishing, constructed to meet code requirements.
An honest note: permits and final approval are issued by your municipality, and no contractor can guarantee them. What we guarantee is construction done properly, to the approved plans, with documentation of the work.

Common Questions
Can you guarantee my basement will be approved as a legal suite?
No — and you should be wary of any contractor who promises that. Approval is issued by your municipality. What we do is build to code requirements and to your approved plans, with proper documentation.
What does a legal basement suite typically need?
Requirements vary by municipality, but generally: adequate ceiling height, egress windows, fire separation between units, sound control, a separate entrance, and code-compliant heating, plumbing and electrical.
How long does a basement suite take to build?
Most full basement suite builds take 6–10 weeks depending on size, bathrooms and kitchenette scope. We confirm your timeline in the written proposal.
Can you work from my architect’s or designer’s drawings?
Yes. If you have approved plans, we build to them. If you’re still planning, we can tell you what’s realistically involved during the site visit.
