Basement Suite Conversion Calgary
Your Basement Is 80% There. We Finish the Other 20%.
Thousands of Calgary homes have finished basements that function as suites but aren’t legally permitted. This means no legal rental protection, no insurance coverage for tenants, and no eligibility for the SSIP rebate program.
Converting an existing finished basement to a legal suite typically requires: adding or upgrading fire separation (drywall, fire-rated doors), installing a separate entrance, ensuring egress windows meet code, adding smoke and CO detectors, and upgrading electrical to separate panels.
Because the basic structure. Framing, drywall, plumbing. Is already in place, conversion projects cost 30 to 50 percent less than ground-up legal suite development. We assess what you have, identify the gaps, and build only what’s needed.
