These are self-contained living spaces, often incorporated within or adjacent to a primary residence, designed for independent living. These units typically include a bedroom, bathroom, kitchenette, and a separate entrance. A common example is an apartment connected to a single-family home, suitable for extended family or renters seeking more privacy than a shared living arrangement offers.
Such residences provide benefits such as accommodating aging parents or other relatives while maintaining a degree of autonomy. They can also serve as rental units, generating income for homeowners. Historically, these arrangements reflected multigenerational living patterns, providing support and companionship within family structures. Modern iterations offer increased privacy and independence for all parties involved.
