What is the code regarding garages that open directly into sleeping areas?

Garages that open directly into sleeping areas are not permitted due to safety and health concerns. The primary reason for this restriction is to prevent the risk of carbon monoxide poisoning and the infiltration of harmful gases and fumes that can emanate from vehicles parked in the garage. Additionally, any fire hazards associated with garage contents or appliances could pose an increased risk to the inhabitants of the sleeping areas.

Building codes generally require a separation between garages and living spaces, typically enforced through fire-rated walls and doors, venting systems, or other safety measures. This separation ensures that any potential hazardous materials, such as automobile exhaust or flammable materials, do not directly affect the occupants of bedrooms or other sleeping spaces. Thus, the prohibition on having a direct opening from a garage to a sleeping area is crucial for ensuring the safety and well-being of residents.
