Where is a fire-wall specifically required?

A fire-wall is specifically required between the dwelling and any attached structures in order to prevent the spread of fire from one area to another. This type of wall acts as a barrier that can withstand fire for a designated period of time, helping to protect the living space of the dwelling from any potential fire hazards originating from a connected structure, such as a garage or storage area. Building codes outline the need for fire-walls in this context to ensure safety and compliance with fire prevention regulations.

Other locations such as between bedrooms and bathrooms, kitchens and baths, or living rooms and bedrooms do not necessitate the same level of fire resistance or separation as required between a dwelling and attachments. The emphasis on fire-walls in the context of attachments reflects their critical role in maintaining safety in the overall building design by controlling fire risk in interconnected spaces.
