Modern modular ADUs can include:

Many look like:

beautiful small homes —

NOT backyard sheds.

Why ADUs Are Growing So Fast Nationwide

ADUs exploded because they help solve MANY modern housing problems:

  • high housing costs

Cities and homeowners increasingly realize:

smaller housing solutions make sense.
