Looking to build an addition onto my house above the garage which is attached to the house. It's a single car garage (12x20). We are are thinking of two options: 1. Turning the garage into a suite with a loft bedroom and 2. building an additional 12x20 space beside the existing garage as the bedroom and turning the 2nd story space (total 24x20) into the living room, kitchen, bathroom space. We'll do the majority of the finishings on the lower end (Ikea or equivalent cabinets, etc). Before I contact contractors I'm just trying to get a ballpark figure for both options.

You really do not have enough information to even give a ballpark. I recommend you contact a draftsmen to draw plans which you will need for City Hall for permits and would give your contractors a good idea to quote from. I suggest you call a trusted pro professional in your area to give you a free quote. Secondary Suites have additional costs to them for instance separate Heating electrical and you need to follow your local city bylaws regarding secondary Suites. Sorry I could not give you a price on your project

Tyler, we need more information before even a "ball-park" figure. "Number one" - is that both ideas need to med standard building codes, which include: structural capabilities, egress windows, electrical and, perhaps, plumbing, and, in the case of an addition, foundation requirements. You'll probably require the assistance of a structural engineer, then send off your application for a building permit. Once that is done, the estimating will follow. Estimates depend on type of material, quality, and time-frame. Hope this helps.

I would recommend working with a professional Architect in your area, so they can review your zoning regulations along with any other restrictions & assess whether your options are possible, or other opportunities that may present themselves.

Once you have addressed those items, you will be better informed on what is, and is not possible and can then assign suitable estimates to your project.

If you have deep pockets, hire a designer and go back and forth between them and a contractor that can build from the designs for your budget. The problem with that is you may discover your dreams are more than your budget if you get my point.

Cheaper & better way would be to find and hire a "design & build" renovator/contractor that can 1) build for your budget with a list of your priorities 2) inform of you what's practical for critical decision making & 3) work with the designer. There are contracts out there that layout a good project format for pricing and arranging this so it doesn't get messy with changes for example.

Otherwise, prepare to get into something that could involve huge costs because designs & engineering are unknowns at this point.
