In which of the following types of buildings is it permitted to have a bathroom containing one water closet, one lavatory, and one bath or shower accessible to the public hallway every 10 occupants?

In hotel buildings, it is typically permitted to have a bathroom that contains one water closet, one lavatory, and one bath or shower accessible to the public hallway for every ten occupants. This arrangement is based on the understanding that hotel guests generally do not require the same level of private bathroom access that is often expected in residential settings. Hotels are designed with a transient population in mind, where shared facilities encourage efficient use of space while still maintaining necessary hygiene standards.

This approach allows hotels to manage costs and maximize occupancy, as guests are usually accustomed to using shared facilities, particularly in situations where they expect basic amenities without the necessity of an en-suite bathroom in every room. The restroom accessibility allows for functional use without sacrificing comfort.

Other types of buildings, however, may adhere to different regulations regarding bathroom access due to the varied needs of their occupants and the intended use of the facilities. For instance, apartment buildings prioritize residential comfort, while commercial and office buildings typically provide separate facilities to accommodate the needs of more significant numbers of staff or clients, often leading to a different standard for the number of restroom fixtures required.
