Bathrooms not more than _____ in area will not require fire sprinklers.

In the context of the International Residential Code (IRC), bathrooms that do not exceed 55 square feet are exempt from the requirement for fire sprinklers. This exemption is established to consider the size and risk factors associated with smaller areas, which are generally less likely to contribute to fire spread compared to more expansive spaces.

The code aims to balance safety with practicality, recognizing that smaller bathrooms have a reduced risk of fire due to their limited size, which inherently narrows the chance of a fire being sustained or spreading. This regulation helps ensure that requirements are commensurate with the potential hazards, thereby allowing for a more efficient use of resources and compliance efforts for both builders and homeowners. Larger bathrooms, meanwhile, present greater risks and therefore may require additional safety measures such as fire sprinklers to protect occupants and property effectively.
