What is the requirement for fire-resistant materials in garages attached to houses?

Fire-resistant materials are crucial in the construction of garages that are attached to houses because they provide an essential barrier between the garage and the living spaces of the home. This requirement is rooted in the need to prevent fire from spreading from a garage, which may contain flammable substances, to the rest of the house where people live.

The International Residential Code specifies that walls, ceilings, and floors separating the garage from the living areas must be constructed using fire-resistant materials. This ensures that in the event of a fire, the spread of flames and heat to the living spaces can be significantly delayed, providing occupants with more time to escape and reducing property damage.

The choices that suggest any other material, such as wood paneling or no specific requirements, do not align with safety standards and building codes designed to safeguard residential properties. Therefore, using fire-resistant materials is a critical requirement for maintaining the safety and integrity of homes with attached garages.
