Cost of drawings to obtain permit

I would like to have an addition done over an existing garage. No change to roofline since there's a big open space over the garage. Though we expect to have to do structural work (new floor support since the existing floor wasn't designed to support living space, and new roof joists since the existing roof supports have to come out), plus we'd like to add a small window for ventilation. Say 400 square feet total, including a bedroom and small bathroom (with some HVAC and plumbing run up through the garage).

What would be the approximate cost of just the drawings and other documents needed to get the permits from the City of Mississauga? I believe I need to get the drawings stamped by a Professional Engineer? Also, any idea what the cost of the permits would be from the City?

I don't want to select a contractor until I have all of the permits in place, so the guy that does the drawings won't necessarily get the actual construction job. I have a really good idea of what I want (plan on copying what a neighbour did years ago), so don't need much 'architectural design'.

Mark,

The cost to produce drawings varies with complexity and the amount of views required by the competent authority. I usually budget between 1 to 5% of project to cover drawings and permits (your actual costs may vary) Most basic projects requiring drawings (decks, sheds, minor additions) would run between $500 to $1,000 including permit.

I've seen municipalities request multiple elevations, lot location, wall cut, foundation plans for outbuildings and freestanding garages, for instance. More drawings = more costs

The permit costs are often based on a basic fee plus a variable component (e.g $25 + $10 per $1,000 of project valuation). Check with your municiplaity for details.They will tell you what kind of drawings and the qualifications that need to be met for the drawings to be accepted.

Hope this helps
