I have a garage that I'm looking to convert to a living quarters. There is a 10' by 10' overhead door that I'd like to remove and replace with a framed 2" by 6" x 10' wall complete with exterior vinyl siding, Tyvek, sheathing, insulation, vapor barrier, and drywall (outside to inside).

My question really is around the requirements for ground contact with the concrete flooring and how to prevent moisture, cold, heat, etc. on the perimeter framing.

If this was new construction you'd be required to have rigid insulation under the concrete and inside or outside of the garage grade beam plus an HVAC system, coarse granular under the concrete c/w sealed vapor barrier, radon/soil gas pipe embedded, interconnected smoke alarm, other electrical requirements, etc. This project should require a building permit (change in use of the space with a value over $5K) + electrical permit. The local authority would then advise you on these and other Code requirements. If you're going without permits best of luck!

Did you get a development permit yet?, Edmonton is not going to grant you one for the build as shown. They do not just allow people to turn their garage into a living quarters like that. The compliance is very extensive both for what is considered a secondary suite, as well as the sizing/zoning of your lot. The utility services installs/permits alone to meet codes & compliance are going to cost you a small fortune. If you just live in a garage personally as homeowner, it is illegal but unless someone reports you not a issue. However if you attempt to rent out as is it is? this is quite illegal and you risk complete shutdown by city and fines. Contact City Planning and Development to get more information on zoning and requirements for secondary suite remodeling.
