You can build .9 multiplied by the lot square footage. for example a standard lot is 25x125 which is 3125sf. multiply this by .9 and you get 2812sf. If you are building a typical 2 story house with a basement that is more than 50% below grade then you divide the 2812sf by 2 floors to get a typical floor plate of 1406sf. you would also have to double check the setbacks and rear yard open space. I suggest consulting an architect such as myself to take this further. I can also help you find a lot that will best suit your design needs.

This is a good question for a zoning attorney. RS districts were created in Chicago to accommodate the development of detached homes on individual lots. Each district is differentiated by the minimum lot area standard. I don't know the set back requirements or on how many square feet you may build.
