What Are ADUs and Why Are They Gaining Popularity?

ADUs, also known as in-law suites or granny flats, are secondary housing units located on the same lot as a primary residence. They can be detached structures, garage conversions, or basement apartments. The rise in their popularity can be attributed to several factors:
