A one and two-family dwelling unit refers to structures designed for residential purposes that accommodate either one household or two separate households, each with their own independent living facilities. This definition aligns perfectly with the description of a building containing up to two dwelling units. These units are typically designed to offer the necessary amenities for independent living, such as a kitchen, bathroom, and living space, which distinguishes them from other types of dwellings.

In contrast, the other options describe different types of housing or accommodation: a building housing three or more units pertains to multi-family residences, while a single facility offering rooms for lodging typically refers to hotels or motels, and a facility providing group accommodations for transient guests describes places like hostels or boarding houses. These alternatives emphasize different structures and usage that do not fall within the definition of a one or two-family dwelling.
