This type of property is characterized by a small area and is suitable for single-family living.

This accessory dwelling unit has such a name because, most often, homeowners build it as housing for elderly family members. However, friends, visiting colleagues, or fellow students of your child can also live in it.

  4. Getting rental income. A granny flat can act as a renting space that you can provide to a young man or girl. It is not suitable for large families; however, this space is adequate enough for the comfortable housing of a single person or a young couple. You will receive money as passive income and will cover construction costs faster.
  5. Low reconstruction cost. Granny flats are very small buildings, the area of which rarely exceeds 300 square feet, and sometimes you can find options for 70 square feet. Accordingly, their construction will not require large investments that will hit your budget. However, any costs for the granny flat are guaranteed to pay off soon.
