Garage door + pedestrian door requirements
LS-GARAGE-DOOR-01Description
Every garage must have exactly one garage_door opening on an exterior wall, plus at least one garage_pedestrian door connecting to an interior room.
Why this exists
A garage needs vehicle access (one garage_door) AND a fire-rated pedestrian connection to the rest of the house. The pedestrian path must be a garage_pedestrian door, not a regular interior door.
