What is prohibited between a dwelling and the garage?

Openings between a dwelling and the garage are prohibited to enhance fire safety and minimize the risk of fire spreading from the garage to the living space. Garages often contain vehicles and equipment that may pose higher fire dangers due to flammable liquids and materials. Having openings, such as doorways or windows, could allow smoke and heat to move more easily into the living areas in case of a fire.

In contrast, solid walls are acceptable as they provide a fire-resistance barrier. Access doors can be installed, but they must be specifically designed and constructed to resist fire, ensuring safe egress from the garage if needed. Windows could be present in some dwellings, but they are typically not recommended in garage walls due to the same fire safety concerns.
