Can 2 bedrooms share an egress window? Both bedrooms have separate entrances. They will share a door that leads to each room. Only 1 bedroom has egress window.
The International Building Code and the International Residential Code both state that you only need a single clear egress path. However, if your maximum occupancy is more than 10 (in an R-1 structure), you are required to have two egress exits.
Two bedrooms with dedicated entry doors and a conjoining doorway should be sufficient. The additional window is a bonus in the one bedroom.
You can also call your local building inspector office for clarification.
