Which of the following locations does not require fire sprinklers?

The linen closet measuring 3 ft x 8 ft is exempt from requiring fire sprinklers due to its small size and the fact that it is not classified as an area with high fire risk or occupancy. According to fire safety codes, fire sprinklers are typically mandated in larger, higher-risk areas where the potential for fire spread is more significant and where occupants might be present for longer durations.

In contrast, areas such as kitchens, bathrooms, and basements are often subjected to different fire safety standards due to their specific risks. Kitchens, for instance, have a higher likelihood of fire hazards due to cooking activities. Bathrooms, while generally smaller, may also have regulations depending on their size and proximity to other living spaces. Basements, depending on their use, can contain electrical appliances and storage that may increase fire risks, thus requiring sprinkler systems.

The specific exemption for the linen closet is a recognition of its limited size and function, making it less likely to contribute to a fire hazard in comparison to larger or more complex spaces.
