Which areas must have at least one emergency escape and rescue opening?

Basements are required to have at least one emergency escape and rescue opening due to safety regulations aimed at ensuring that occupants can safely evacuate in case of an emergency, such as a fire. The presence of such openings is crucial because basements are often below ground level, making it difficult to escape through conventional exits. Additionally, these openings provide a means for emergency personnel to enter and assist individuals who may be trapped or in need of help.

In contrast, attics typically do not require emergency escape openings unless they are habitable spaces, as most attics are not intended for occupancy. Garages are not typically seen as places where people sleep or reside, so they do not have the same requirements for emergency escape. Living rooms, while important for day-to-day activities, generally do not need emergency escape openings if they have direct access to exits that occupants can use in case of an emergency. Thus, basements stand out as an area where safety regulations mandate such openings to ensure occupant safety.
