Basement – Egress Access through garage

basementegress

I am looking to finish our basement and add two bedrooms. The basement has one stairway access from the basement to the main level of the home. Additionally, it has another stairway access from the basement to the garage.

I currently have four non-egress windows in the basement. I am hoping to add two bedrooms with two windows each.

Can I do this, without needing to add an egress window in the basement bedrooms? Does having a second stairway access to the garage count as a walk-out? Does having a second stairway access to the garage mean I don't need an egress window in the future finished bedroom?

Basements and every sleeping room shall have at least one operable emergency and rescue opening. Such opening shall open directly into a public street, public alley, yard or court.

IRC R310.1

Egress must be available through a window to the outdoors, such that an adult can be reasonably expected to pass through to escape or to provide rescue. Down a hall, up some stairs, and through a garage or other part of the structure doesn't meet that requirement under most applicable codes, nor is it the kind of "escape route" you'd really want for your loved ones.
