8% natural light and 4% natural ventilation for each habitab

[Darren Hitz]

I will be calling on Egress company to come in and expand window is basement bedroom. I was reviewing the Ann Arbor code for basement dwelling:

1. 8% natural light and 4% natural ventilation for each habitable room

Point number one is my concern. The egress will cover the bedroom but as you will see by attached picture the living room (at bottom of stairs, doorway from here into bedroom with proposed egress) may be a problem. Now maybe that means that they don't deem the living room in basement as "habitable" which is fine, but if somehow eliminates using the entire bedroom downstairs as living space then is problem. 

I read that you can use an adjoining room but you would need something bigger than a door between them (50% of shared wall)

I want to know before I get egress company to come in. If I wait till Inspection from city it may be too quick a turn around and too big a hassle. My 3 bedroom 2 bath would go to a 2 bedroom 1 bath without basement

Does anyone have any thoughts on this. 

thanks

Darren
