Tiny House Friendly: 3⁄10
- Tiny house regulations and codes vary by city, town, or county.
- Madison defines tiny houses on wheels that are no more than 150 square feet as “portable shelters.”
- Dane County allows accessory dwelling units (ADUs) that are no more than 800 square feet.
Tiny houses on foundations can be classified as ADUs in most instances; while tiny houses on wheels may find the process far more difficult.
