casita

Casita is a Spanish word meaning "small house" or "cottage." It is the diminutive form of casa ("house"), formed with the suffix -ita. In general use, casita refers to a small dwelling, and in English-speaking contexts it often designates a guesthouse or secondary dwelling on a property.

In many Spanish-speaking countries, a casita can be a modest rural dwelling, a servant's quarters on a larger estate, or a small urban home. Historically, casitas appeared as ancillary structures on haciendas or estates; the term emphasizes intimacy or simplicity.

In the United States and other markets, casita commonly describes an accessory dwelling unit (ADU) or standalone guesthouse on a residential lot. A casita typically has a separate entrance and may include basic living facilities such as a kitchen and bathroom, depending on local regulations and design.

Designs range from traditional adobe casitas to modern prefab or modular units, often marketed for vacation properties, long-term rental, or multigenerational living. The term conveys a sense of charm and privacy, distinct from the main residence.
