People have different opinions on what constitutes a “tiny” house. However, most experts agree that a tiny house is any dwelling unit that is 400 square feet or less in size. This includes both traditional houses and RVs (recreational vehicles).
Some people believe that a true tiny house must be 100 square feet or less. Others believe that anything under 500 square feet is considered tiny.
The main point is that a tiny house is significantly smaller than a traditional home. It is usually about one-third the size of a typical home in the United States, which averages around 2,600 square feet.
