Basement Development & Remodeling in Calgary

Unfinished-to-finished basement development runs $50–$120 per square foot, so most Calgary basements land in the $60,000–$140,000 range. Adding a legal suite (separate kitchen, full bath, egress, fire separation) bumps the upper end.

Allow 8–14 weeks of construction once permits are issued, plus 4–8 weeks for permit application and design. Legal suites trend toward the upper end because of the inspection sequence.

Yes — any basement with a new bathroom, bedroom, or kitchen needs a City of Calgary building permit. Adding a secondary suite also needs a development permit. We file both and handle the inspections.

Calgary requires a separate entrance, an egress window in the bedroom, a fire-rated separation between the suite and main dwelling, a working smoke + CO alarm system, sound attenuation, and minimum ceiling height (typically 6′5″).

Only if the development permit allows it and the suite passes Safety Codes inspection. We build to the standard from day one so you can register the suite with the City after final inspection.
