What is a Casita?

A casita is a separate structure constructed on the grounds of another house. The term "casita" means “little house” in Spanish. The building style first appeared in the dorms for migrant workers in the southwest. You'll typically find casitas in cities like Phoenix, Santa Fe, Las Vegas, and other areas of the southwest. However, the trend has exponentially grown in many forms across the US as cities and counties relax the building laws to provide much needed additional housing. These structures are also known as mother-in-law suites, carriage houses, guest houses, pool houses, and so on. However, the concept is the same: a semi-detached or smaller detached unit constructed on the grounds of a larger estate.
