What defines home size? When is a dwelling “tiny”? While tiny homes can come in a variety of shapes and sizes — from a steel container to a yurt to a building on a trailer base — the average size is 100 to 400 square feet. Depending on which sources you consult, some argue vehemently that a residence can’t be considered tiny unless it is 500 square feet or smaller. Others insist on 700 square feet or less. Yet others limit it to under 1000 square feet. There are some limitations depending on the housing base/foundation. Building and transportation regulations dictate height, length, and weight limits for homes built on trailer bases.
To complicate matters, states (and counties and cities) outline different ordinances for shelters based on building and zoning laws. That means one county may allow a small skoolie without plumbing as a primary dwelling while another may require plumbing (that meets building codes) in the dwelling. Some require the housing be on a permanent foundation. Others do not care. Unrestricted areas allow homes of any size. Restricted areas decide minimum home size. Unfortunately, smaller home sizes do not usually find favor. However, that is changing.
In 2022, Census.gov reported the “median size of a completed single-family home was 2,299 square feet”. They also reported the “median size of a new single-family home sold in 2022 was 2,383 square feet.” It’s fair to say then even a tiny home with a larger size of 900 square feet, is still small in comparison to the median size family home.
Size typically dictates the definition as the structure itself will come in a variety of materials, shapes, and mobility options. Take a look at the glossary of home types.
