Just like a home, the cost per square foot for an ADU depends on a variety of factors such as size, site considerations, and your design choices. The larger the total square footage, the smaller the per-square-foot costs. People are often surprised by the cost of an ADU. However, bear in mind that an ADU is essentially a small home, requiring all the same components of a larger house. Kitchens and bathrooms are the most costly elements of a home, and while the footprint of an ADU may be smaller, there’s only so small a toilet or sink can get.
