How Do I Determine The Amount Of Light Required In A Residential Building ? Is There A Code For This , If So What Is It ? The Info That I Was Told Is , 3 Watts Per Square Foot ( Thats A Lot Of Bulbs )

With the exception of staircases, I have never heard of a minimum lighting requirement. There is a requirement for switched outlets in all habitable rooms but I don't recall anything about what size bulb you have to put in them.
Why would this be of any concern? Most people today want enough light to keep their waffles warm.

Ask your architect. That's what you pay him for. You do have an architect, right?

That's what lighting designers are for now adays.

But there are simple 'rules' that most people apply, such as the can lights spread light over a 5 foot radius, to help you figure it out. Experience is your best friend in something like this if you are doing it yourself. It comes down to each individual light and what it is going to do, unless you are just trying to come up with a service panel load to determine your panel.
