The term “tiny house” is a popular marketing term that can refer to various types of structures and dwellings that range from tiny shelters for the homeless to Park Model RVs for seasonal use to tiny homes built for permanent residence. Within the tiny home industry, a tiny house generally refers to a single dwelling unit of less than 400 square feet in area, built on a permanent or movable foundation. The terms “tiny house,” “movable tiny house,” “tiny house on wheels” (aka THOW), or other similar words may be included in the verbiage of state laws, local zoning ordinances, and local residential building codes. These terms commonly refer to dwellings suitable for full-time habitation. In contrast, the term “tiny shelter” often refers to a detached building without key building elements normally required for full-time residential use (for example, without a full kitchen or sanitary sewer connection). Tiny shelters are usually intended primarily to provide temporary sleeping accommodations and protection from the weather.
